IMPACT OF COVID-19

IMPACT OF COVID-19	6 Months Ended

Extraordinary And Unusual Items [Abstract]
IMPACT OF COVID-19	NOTE 2 — IMPACT OF COVID-19 The COVID-19 pandemic has disrupted business, trade, commerce, and financial and credit markets in the U.S. and globally. Orion’s business has been adversely impacted by measures taken by government entities and others to control the spread of the virus beginning in March 2020, the last month of its fiscal 2020 year. As a deemed essential business, Orion provides products and services to ensure energy and lighting infrastructure and Orion therefore continues to operate throughout the pandemic. Orion has implemented a number of safety protocols, including limiting travel, restricting access to our facilities along with monitoring processes, physical distancing, physical barriers, enhanced cleaning procedures, and requiring face coverings. Nonetheless, Orion did experience a material adverse effect from the COVID-19 pandemic due to the curtailment of activity in the last few weeks of the 2020 fiscal year and during the first half of fiscal 2021, including the delay of project installations for a major national account customer. This project resumed during the second quarter of fiscal 2021. As part of Orion’s response to the impacts of the COVID-19 pandemic, during the fourth quarter of fiscal 2020, Orion implemented a number of cost reduction and cash conservation measures, including reducing headcount. Orion recognized $0.4 million in restructuring expense during the fourth quarter of fiscal 2020. As of September 30, 2020, all of the restructuring accrual had been paid. While certain restrictions began to initially lessen in certain jurisdictions during the first half of Orion’s fiscal 2021, stay-at-home, face mask or lockdown orders remain in effect in others, with employees asked to work remotely if possible. Certain areas of the country have seen a spike of COVID-19 cases (including in Manitowoc, Wisconsin), which could result in renewed restrictions and lockdown orders. Some customers and projects are in areas where travel restrictions have been imposed, certain customers have either closed or reduced on-site activities, and timelines for the completion of multiple projects have been extended. At this time, it is not possible to predict the overall impact the COVID-19 pandemic will have on Orion’s business, liquidity, capital resources or financial results. However, Orion does expect that the economic and regulatory impacts of COVID-19 will materially and adversely impact revenue and profitability in fiscal 2021. If there is prolonged adverse impact, Orion’s business, liquidity, capital resources, financial results, and the carrying values of Orion’s property, plant and equipment and intangible assets may be impacted negatively. Orion will continue to actively monitor the situation and may take further actions that alter business operations. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law and includes certain income tax provisions relevant to businesses. Orion is required to recognize the effect on the consolidated financial statements in the period the law was enacted, which is the period ended March 31, 2020. For the fiscal year ended March 31, 2020, and three and six months ended September 30, 2020, the CARES Act did not have a material impact on Orion’s consolidated financial statements. See Note 14 – Income Taxes.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of Orion Energy Systems, Inc. and its wholly owned subsidiaries. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Orion have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2021 or other interim periods. The Condensed Consolidated Balance Sheet at March 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in Orion’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020 filed with the SEC on June 5, 2020. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, inventory obsolescence and allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates. Concentration of Credit Risk and Other Risks and Uncertainties Orion's cash is deposited with two financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including ballasts, lamps and LED components, from multiple suppliers. For the three months ended September 30, 2020, one supplier accounted for 10.3% of total cost of revenue. For the six months ended September 30, 2020, no supplier accounted for more than 10% of total cost of revenue. For the three months ended September 30, 2019, two suppliers accounted for 17.2% and 10.0% of total cost of revenue, respectively. For the six months ended September 30, 2019, one supplier accounted for 15.5% of total cost of revenue For the three months ended September 30, 2020, one customer accounted for 60.7% of total revenue. For the six months ended September 30, 2020, two customers accounted for 44.4% and 14.9% of total revenue, respectively. For the three months ended September 30, 2019, one customer accounted for 81.1% of total revenue. For the six months ended September 30, 2019, one customer accounted for 79.2% of total revenue. As of September 30, 2020, one customer accounted for 70.9 % of accounts receivable. As of March 31, 2020, two customers accounted for 37.3% and 13.0% of accounts receivable, respectively. Recent Accounting Pronouncements Issued: Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Since the issuance of ASU 2016-13, the FASB released several amendments to improve and clarify the implementation guidance. The provisions of ASU 2016-13 and the related amendments are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Orion is currently evaluating the impact of adoption of this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general rules of Topic 740. The provisions of ASU 2019-12 are effective for Orion for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Orion is currently evaluating the impact of adoption on this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures.

REVENUE

REVENUE	6 Months Ended
	Sep. 30, 2020
Revenue From Contract With Customer [Abstract]
REVENUE	General Information Orion generates revenues primarily by selling commercial LED lighting fixtures and components, including controls and integrated IoT capabilities, and by installing these fixtures in its customer’s facilities on a turnkey basis via a dedicated installation and support team. Orion recognizes revenue in accordance with the guidance in ASC 606 when control of the goods or services being provided (which Orion refers to as a performance obligation) is transferred to a customer at an amount that reflects the consideration that management expects to receive in exchange for those goods or services. Prices are generally fixed at the time of order confirmation. The amount of expected consideration includes estimated deductions and early payment discounts calculated based on historical experience, customer rebates based on agreed upon terms applied to actual and projected sales levels over the rebate period, and any amounts paid to customers in conjunction with fulfilling a performance obligation. If there are multiple performance obligations in a contract, the contract’s total sales price is allocated to each individual performance obligation based on their relative standalone selling price. A performance obligation’s standalone selling price is the price at which Orion would sell such promised good or service separately to a customer. Orion uses an observable price to determine the stand-alone selling price for separate performance obligations or a cost-plus margin approach when one is not available. The cost-plus margin approach is used to determine the stand-alone selling price for the installation performance obligation and is based on average historical installation margin. Revenue derived from customer contracts which include only performance obligation(s) for the sale of lighting fixtures and components is classified as Product revenue in the Condensed Consolidated Statements of Operations. The revenue for these transactions is recorded at the point in time when management believes that the customer obtains control of the products, generally either upon shipment or upon delivery to the customer’s facility. This point in time is determined separately for each contract and requires judgment by management of the contract terms and the specific facts and circumstances concerning the transaction. Revenue from a customer contract which includes both the sale of fixtures and the installation of such fixtures (which Orion refers to as a turnkey project) is allocated between each lighting fixture and the installation performance obligation based on relative standalone selling prices. Revenue from turnkey projects that is allocated to the sale of the lighting fixtures is recorded at the point in time when management believes the customer obtains control of the product(s) and is reflected in Product revenue. This point in time is determined separately for each customer contract based upon the terms of the contract and the nature and extent of Orion’s control of the light fixtures during the installation. Product revenue associated with turnkey projects can be recorded (a) upon shipment or delivery, (b) subsequent to shipment or delivery and upon customer payments for the light fixtures, (c) when an individual light fixture is installed and working correctly, or (d) when the customer acknowledges that the entire installation project is substantially complete. Determining the point in time when a customer obtains control of the lighting fixtures in a turnkey project can be a complex judgment and is applied separately for each individual light fixture included in a contract. In making this judgment, management considers the timing of various factors, including, but not limited to, those detailed below: • when there is a legal transfer of ownership; • when the customer obtains physical possession of the products; • when the customer starts to receive the benefit of the products; • the amount and duration of physical control that Orion maintains on the products after they are shipped to, and received at, the customer’s facility; • whether Orion is required to maintain insurance on the lighting fixtures when they are in transit and after they are delivered to the customer’s facility; • when each light fixture is physically installed and working correctly; • when the customer formally accepts the product; and • when Orion receives payment from the customer for the light fixtures. Revenue from turnkey projects that is allocated to the single installation performance obligation is reflected in Service revenue. Service revenue is recorded over-time as Orion fulfills its obligation to install the light fixtures. Orion measures its performance toward fulfilling its performance obligations for installations using an output method that calculates the number of light fixtures removed and installed as of the measurement date in comparison to the total number of light fixtures to be removed or installed under the contract. Most products are manufactured in accordance with Orion’s standard specifications. However, some products are manufactured to a customer’s specific requirements with no alternative use to Orion. In such cases, and when Orion has an enforceable right to payment, Product revenue is recorded on an over-time basis measured using an input methodology that calculates the costs incurred to date as compared to total expected costs. There was no over-time revenue related to custom products recognized in the three and six months ended September 30, 2020 and September 30, 2019. Orion also records revenue in conjunction with several limited power purchase agreements (“PPAs”) still outstanding. Those PPAs are supply-side agreements for the generation of electricity. Orion’s last PPA expires in 2031. Revenue associated with the sale of energy generated by the solar facilities under these PPAs is within the scope of ASC 606. Revenues are recognized over-time and are equal to the amount billed to the customer, which is calculated by applying the fixed rate designated in the PPAs to the variable amount of electricity generated each month. This approach is in accordance with the “right to invoice” practical expedient provided for in ASC 606. Orion also recognizes revenue upon the sale to third parties of tax credits received from operating the solar facilities and from amortizing a grant received from the federal government during the period starting when the power generating facilities were constructed until the expiration of the PPAs; these revenues are not derived from contracts with customers and therefore not under the scope of ASC 606. When shipping and handling activities are performed after a customer obtains control of the product, Orion has elected to treat shipping and handling costs as an activity necessary to fulfill the performance obligation to transfer product to the customer and not as a separate performance obligation. Any shipping and handling costs charged to customers are recorded in Product revenue. Shipping and handling costs are accrued and included in Cost of product revenue. See Note 11 – Accrued Expenses and Other for a discussion of Orion’s accounting for the warranty it provides to customers for its products and services. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Contract Fulfillment Costs Costs associated with product sales are accumulated in inventory as the fixtures are manufactured and are transferred to Cost of product revenue at the time revenue is recorded. See Note 6 – Inventories, Net. Costs associated with installation sales are expensed as incurred. Disaggregation of Revenue Orion’s Product revenue includes revenue from contracts with customers accounted for under the scope of ASC 606 and revenue which is accounted for under other guidance. For the three and six months ended September 30, 2020, Product revenue included $0.9 million and $1.4 million, respectively, derived from sales-type leases for light fixtures, $0.1 million and $ million, respectively, derived from the sale of tax credits generated from Orion’s legacy operation for distributing solar energy, and $19 thousand and $38 thousand, respectively, derived from the of federal grants in 2010 and 2011 as reimbursement for a portion of the costs to construct the legacy solar facilities which are not under the scope of ASC 606. For the three and six months ended September 30, 2019, Product revenue included $0.6 million and $1.0 million, respectively, derived from sales-type leases for light fixtures, $0.1 million derived from the sale of tax credits generated from Orion’s legacy operation for distributing solar energy, and $19 thousand and $38 thousand, respectively, derived from the amortization of federal grants received in 2010 and 2011 as reimbursement for a portion of the costs to construct the legacy solar facilities which are not under the scope of ASC 606. All remaining Product revenue, and all Service revenue, are derived from contracts with customers as defined in ASC 606. The primary end-users of Orion’s lighting products and services are (a) commercial or industrial companies and (b) the federal government. Commercial or industrial end-users obtain Orion products and services through turnkey project sales or by purchasing products either direct from Orion or through distributors or energy service companies ("ESCOs"). Revenues associated with commercial and industrial end-users are included within each of Orion’s segments, dependent on the sales channel. The federal government obtains Orion products and services primarily through turnkey project sales that Orion makes to a select group of contractors who focus on the federal government. Revenues associated with government end-users are primarily included in the Orion Engineered Systems Division segment. See Note 18 – Segments, for additional discussion concerning Orion’s reportable segments. The following tables provide detail of Orion’s total revenues for the three and six months ended September 30, 2020 and September 30, 2019 (dollars in thousands): Three Months Ended September 30, 2020 Six Months Ended September 30, 2020 Product Services Total Product Services Total Revenue from contracts with customers: Lighting revenues, by end user Federal government $ 85 $ 26 $ 111 $ 135 $ 26 $ 161 Commercial and industrial 18,816 5,995 24,811 27,525 7,105 34,630 Total lighting 18,901 6,021 24,922 27,660 7,131 34,791 Solar energy related revenues 20 — 20 42 — 42 Total revenues from contracts with customers 18,921 6,021 24,942 27,702 7,131 34,833 Revenue accounted for under other guidance 1,339 — 1,339 2,259 — 2,259 Total revenue $ 20,260 $ 6,021 $ 26,281 $ 29,961 $ 7,131 $ 37,092 Three Months Ended September 30, 2019 Six Months Ended September 30, 2019 Product Services Total Product Services Total Revenue from contracts with customers: Lighting revenues, by end user Federal government $ 166 $ 52 $ 218 $ 824 $ 298 $ 1,122 Commercial and industrial 34,758 12,698 47,456 65,942 22,491 88,433 Total lighting 34,924 12,750 47,674 66,766 22,789 89,555 Solar energy related revenues 22 — 22 41 — 41 Total revenues from contracts with customers 34,946 12,750 47,696 66,807 22,789 89,596 Revenue accounted for under other guidance 626 — 626 1,104 — 1,104 Total revenue $ 35,572 $ 12,750 $ 48,322 $ 67,911 $ 22,789 $ 90,700 Cash Flow Considerations Customer payments for material-only orders are due shortly after shipment. Turnkey projects where the end-user is a commercial or industrial company typically span between one week to three months. Customer payment requirements for these projects vary by contract. Some contracts provide for customer payments for products and services as they are delivered, other contracts specify that the customer will pay for the project in its entirety upon completion of the installation. Turnkey projects where the end-user is the federal government typically span a three to six-month period. The contracts for these sales often provide for monthly progress payments equal to ninety percent (90%) of the value provided by Orion during the month. Orion provides long-term financing to one customer who frequently engages Orion in large turnkey projects that span between three and nine months. The customer executes an agreement providing for monthly payments of the contract price, plus interest, over a five-year period. The total transaction price in these contracts is allocated between product and services in the same manner as all other turnkey projects. The portion of the transaction associated with the installation is accounted for consistently with all other installation related performance obligations. The portion of the transaction associated with the sale of the multiple individual light fixtures is accounted for as sales-type leases in accordance with the guidance for leases. Revenues associated with the sales-type leases are included in Product revenue and recorded for each fixture separately based on the customer’s monthly acknowledgment that specified fixtures have been installed and are operating as specified. The payments associated with these transactions that are due during the twelve months subsequent to September 30, 2020 are included in Accounts receivable, net in Orion’s Condensed Consolidated Balance Sheets. The remaining amounts due that are associated with these transactions are included in Other long-term assets in Orion’s Condensed Consolidated Balance Sheets. The customer’s monthly payment obligation commences after completion of the turnkey project. Orion generally sells the receivable from the customer to an independent financial institution either during, or shortly after completion of, the installation period. Upon execution of the receivables purchase / sales agreement, all amounts due from the customer are included in Revenues earned but not billed on Orion’s Condensed Consolidated Balance Sheets until cash is received from the financial institution. The financial institution releases funds to Orion based on the customer’s monthly acknowledgment of the progress Orion has achieved in fulfilling its installation obligation. Orion provides the progress certifications to the financial institution one month in arrears. The total amount received from the sales of these receivables during the three and six months ended September 30, 2020, was $2.1 million and $2.3 million, respectively. Orion’s losses on these sales were $9 thousand for the three and six months ended September 30, 2020 and are included in Interest expense in the Condensed Consolidated Statements of Operations. The total amount received from the sales of these receivables during the three months ended three and six months ended September 30, 2019 was $0.9 million and $3.7 million, respectively. Orion’s losses on these sales were $23 thousand and $70 thousand for the three and six months ended September 30, 2019, respectively and are included in Interest expense in the Condensed Consolidated Statement of Operations. Practical Expedients and Exemptions Orion expenses sales commissions when incurred because the amortization period is one year or less. These costs are recorded within Sales and marketing expense. There are no other capitalizable costs associated with obtaining contracts with customers. Orion’s performance obligations related to lighting fixtures typically do not exceed nine months in duration. As a result, Orion has elected the practical expedient that provides an exemption to the disclosure requirements regarding information about value assigned to remaining performance obligations on contracts that have original expected durations of one year or less. Orion also elected the practical expedient that permits companies to not disclose quantitative information about the future revenue when revenue is recognized as invoices are issued to customers for services performed. Other than the turnkey projects which result in sales-type leases discussed above, Orion generally receives full payment for satisfied performance obligations in less than one year. Accordingly, Orion does not adjust revenues for the impact of any potential significant financing component as permitted by the practical expedients provided in ASC 606. Contract Balances A receivable is recognized when Orion has an enforceable right to payment in accordance with contract terms and an invoice has been issued to the customer. Payment terms on invoiced amounts are typically 30 days from the invoice date. Revenue earned but not billed represents revenue that has been recognized in advance of billing the customer, which is a common practice in Orion turnkey contracts. Once Orion has an unconditional right to consideration under a turnkey contract, Orion typically bills the customer accordingly and reclassifies the amount to Accounts receivable, net. Revenue earned but not billed as of September 30, 2020, and March 31, 2020, includes $21 thousand and $39 thousand, respectively, which was not derived from contracts with customers and therefore not classified as a contract asset as defined by ASC 606. Deferred revenue, current as of September 30, 2020, and March 31, 2020, includes $0.1 million and $31 thousand, respectively, of contract liabilities which represent consideration received from customers prior to the point that Orion has fulfilled the promises included in a performance obligation and recorded revenue. Deferred revenue, long-term consists of the unamortized portion of the funds received from the federal government in 2010 and 2011 as reimbursement for the costs to build the two facilities related to the PPAs. As the transaction is not considered a contract with a customer, this value is not a contract liability as defined by ASC 606. The following chart shows the balance of Orion’s receivables arising from contracts with customers, contract assets and contract liabilities as of September 30, 2020 and March 31, 2020 (dollars in thousands): September 30, 2020 March 31, 2020 Accounts receivable, net $ 17,019 $ 10,427 Contract assets $ 3,260 $ 1,082 Contract liabilities $ 141 $ 31 There were no significant changes in the contract assets outside of standard reclassifications to Accounts receivable, net upon billing. There were no significant changes to contract liabilities.

LEASES

Leases [Abstract]
LEASES	NOTE 9 — LEASES From time to time, Orion leases assets from third parties. Orion also leases certain assets to third parties. Whether it is the lessee or the lessor, Orion’s determination of whether a contract includes a lease, and assessing how the lease should be accounted for, is a matter of judgment based on whether the risks and rewards, as well as substantive control of the assets specified in the contract, have been transferred from the lessor to the lessee. The judgment considers matters such as whether the assets are transferred from the lessor to the lessee at the end of the contract, the term of the agreement in relation to the asset’s remaining economic useful life, and whether the assets are of such a specialized nature that the lessor will not have an alternative use for such assets at the termination of the agreement. Other matters requiring judgment are the lease term when the agreement includes renewal or termination options and the interest rate used when initially determining the right of use (“ROU”) asset and lease liability. ROU assets represent Orion’s right to use an underlying asset for the lease term and lease liabilities represent Orion’s obligation to make lease payments arising from the lease. Under ASC 842, both finance and operating lease ROU assets and lease liabilities for leases with initial terms in excess of 12 months are recognized at the commencement date based on the present value of lease payments over the lease term. When available, Orion uses the implicit interest rate in the lease when completing this calculation. However, as most of Orion’s operating lease agreements generating ROU assets do not provide the implicit rate, Orion’s incremental borrowing rate under its line of credit, adjusted for differences in duration and the relative collateral value in relation to the payment obligation, at the commencement of the lease is generally used in this calculation. The lease term includes options to extend or renew the agreement, or for early termination of the agreement, when it is reasonably certain that Orion will exercise such option. ROU assets are depreciated using the straight-line method over the lease term. Orion recognizes lease expense for leases with an initial term of 12 months or less, referred to as short term leases, on a straight-line basis over the lease term. One of Orion’s frequent customers purchases products and installation services under agreements that provide for monthly payments, at a fixed monthly amount, of the contract price, plus interest, typically over a five-year period. While Orion retains ownership of the light fixtures during the financing period, the transaction terms and the underlying economics associated with used lighting fixtures results in Orion essentially ceding ownership of the lighting fixtures to the customer after completion of the agreement. The portions of the transaction associated with the sale of the light fixtures is accounted for as a sales-type lease. The total transaction price in these contracts is allocated between the lease and non-lease components in the same manner as the total transaction price of other turnkey projects containing lighting fixtures and installation services. Orion leases portions of its corporate headquarters to third parties; all such agreements have been, and continue to be, classified as operating leases under the applicable authoritative accounting guidance. The assets being leased continue to be included in Property and equipment, net. Lease payments earned are recorded as a reduction in administrative expenses. Assets Orion Leases from Other Parties On January 31, 2020, Orion entered into the current lease for its approximately 266,000 square foot primary manufacturing and distribution facility in Manitowoc, WI. The lease has a 10-year term, with the option to terminate after six years. Orion is responsible for the costs of insurance and utilities for the facility. These costs are considered variable lease costs. The agreement is classified as an operating lease. The prior lease agreement for this facility provided the lessor the right to terminate the lease agreement at any time with 12 months’ notice to Orion. As a result, the agreement was previously classified as a short-term lease. In February 2014, Orion entered into a multi-year lease agreement for use of approximately 10,500 square feet of office space in a multi-use office building in Jacksonville Florida. The lease has since been extended, most recently during the first quarter of fiscal 2021, and presently terminates on June 30, 2023. The agreement is classified as an operating lease. Orion has leased other assets from third parties, principally office and production equipment. The terms of our other leases vary from contract to contract and expire at various dates throughout 2020. A summary of Orion’s assets leased from third parties follows (dollars in thousands): Balance sheet classification September 30, 2020 March 31, 2020 Assets Operating lease assets Other long-term assets $ 2,830 $ 2,745 Liabilities Current liabilities Operating lease liabilities Accrued expenses and other $ 611 $ 691 Non-current liabilities Operating lease liabilities Other long-term liabilities 2,966 2,830 Total lease liabilities $ 3,577 $ 3,521 Orion had operating lease costs of $0.2 million and $0.4 million for the three and six months ended September 30, 2020. Orion had operating lease costs of $0.1 million and $0.3 million for the three and six months ended September 30, 2019. The estimated maturity of lease liabilities for each of the next five years is shown below (dollars in thousands): Maturity of Lease Liabilities Operating Leases Fiscal 2021 (period remaining) $ 393 Fiscal 2022 798 Fiscal 2023 820 Fiscal 2024 746 Fiscal 2025 735 Thereafter 628 Total lease payments $ 4,120 Less: Interest (543 ) Present value of lease liabilities $ 3,577 Assets Orion Leases to Other Parties Orion provides long-term financing to one customer who frequently engages Orion in large turnkey projects that span between three and nine months. The customer executes an agreement providing for monthly payments, at a fixed monthly amount, of the contract price, plus interest, over typically a five-year period. The total transaction price in these contracts is allocated between product and services in the same manner as all other turnkey projects. The portion of the transaction associated with the installation is accounted for consistently with all other installation related performance obligations under ASC 606. While Orion retains ownership of the light fixtures during the financing period, the transaction terms and the underlying economics associated with used lighting fixtures results in Orion essentially ceding ownership of the lighting fixtures to the customer after completion of the agreement. Therefore, the portions of the transaction associated with the sale of the multiple individual light fixtures is accounted for as a sales-type lease under ASC 842. Revenues, and production and acquisition costs, associated with sales-type leases are included in Product revenue and Costs of product revenues in the Condensed Consolidated Statement of Operations. These amounts are recorded for each fixture separately based on the customer’s monthly acknowledgment that specified fixtures have been installed and are operating as specified. The execution of the acknowledgement is considered the commencement date as defined in ASC 842. The following chart shows the amount of revenue and cost of sales arising from sales-type leases during the three and six months ended September 30, 2020 and September 30, 2019 (dollars in thousands): Three Months Ended September 30, Six Months Ended September 30, 2020 2019 2020 2019 Product revenue $ 938 $ 606 $ 1,382 $ 1,002 Cost of product revenue $ 813 $ 541 $ 1,251 $ 901 The Condensed Consolidated Balance Sheets as of September 30, 2020 and March 31, 2020 includes an immaterial amount related to the net investment in sales-type leases as amounts due from the customer associated with lighting fixtures that were acknowledged to be installed and working correctly prior to period end were not transferred to the financing institution prior to the respective balance sheet dates. Other Agreements where Orion is the Lessor Orion has leased unused portions of its corporate headquarters to third parties. The length and payment terms of the leases vary from contract to contract and, in some cases, include options for the tenants to extend the lease terms. Annual lease payments are recorded as a reduction in administrative operating expenses and were not material in the three and six months ended September 30, 2020 or September 30, 2019. Orion accounts for these transactions as operating leases.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER COMMON SHARE	NOTE 12 — NET INCOME (LOSS) PER COMMON SHARE For the six months ended September 30, 2020, Orion was in a net loss position; therefore, the Basic and Diluted weighted-average shares outstanding are equal because any increase to the basic shares would be anti-dilutive. Basic and Diluted net income (loss) per common share was calculated based upon the following: For the Three Months Ended September 30, For the Six Months Ended September 30, 2020 2019 2020 2019 Numerator: Net income (loss) (in thousands) $ 1,914 $ 6,721 $ (305 ) $ 10,689 Denominator: Weighted-average common shares outstanding 30,669,272 30,189,067 30,511,611 29,957,541 Weighted-average common shares and common share equivalents outstanding 31,170,139 30,830,381 30,511,611 30,757,863 Net income (loss) per common share: Basic $ 0.06 $ 0.22 $ (0.01 ) $ 0.36 Diluted $ 0.06 $ 0.22 $ (0.01 ) $ 0.35 Orion uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires Orion to compute total proceeds as the sum of the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributable to future services. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on net income per common share during periods with net income, and accordingly, Orion excludes them from the calculation. Due to the net loss incurred during the six months ended September 30, 2020, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, was not included in the diluted loss per common share calculation for those periods.

On June 3, 2019, Orion and certain of its subsidiaries entered into an amendment to the Credit Agreement, which increased the maximum borrowing base credit available for certain of the customer receivables included in Orion’s borrowing base and provided for a borrowing base credit of up to $3.0 million based on inventory, in each case, subject to certain conditions. On August 2, 2019, Orion and certain of its subsidiaries entered into a second amendment to the Credit Agreement, which established a rent reserve in an amount equal to three months’ rent payable at any leased location where Orion maintains inventory included in its borrowing base and provided for a reduction of the borrowing base credit that Orion may receive for inventory if Orion defaults under the lease for any such location. On November 21, 2019, Orion and certain of its subsidiaries entered into a third amendment to the Credit Agreement, which extended the maturity date from October 26, 2020 to October 26, 2021; increased the sublimit under the Credit Agreement for advances under business credit cards from $1.5 million to $3 million; created a new $2 million sublimit permitting entry into foreign currency forward contracts with the lender; expanded Orion’s ability to make capital expenditures and incur other debt from time to time; and permitted the lender to amend the financial covenant included in the Credit Agreement (which requires the maintenance of a certain amount of unrestricted cash on deposit with the lender at the end of each month) upon receipt of Orion’s annual projections. The Credit Agreement, as amended, provides for a revolving credit facility (the “Credit Facility”) maturing on October 26, 2021. Borrowings under the Credit Facility are currently limited to $20.15 million, subject to a borrowing base requirement based on eligible receivables and inventory. The Credit Agreement, as amended, includes a $2.0 million sublimit for the issuance of letters of credit. As of September 30, 2020, Orion’s borrowing base was $16.4 million, and Orion had $7.9 million borrowings outstanding. Orion had no outstanding letters of credit leaving total borrowing availability of $8.5 million. While Orion’s borrowings under the Credit Agreement are currently recorded as a long-term liability on our balance sheet, Orion expects this characterization to change to a current liability during the third quarter as the Credit Agreement will then mature in less than 12 months. The Credit Agreement is secured by a security interest in substantially all of Orion's and its subsidiaries’ personal property. Borrowings under the Credit Agreement generally bear interest at floating rates based upon the prime rate (but not less than 5.00% per year) plus an applicable margin determined by reference to Orion’s quick ratio (defined as the aggregate amount of unrestricted cash, unrestricted marketable securities and, with certain adjustments, receivables convertible into cash divided by total current liabilities, including the obligations under the Credit Agreement). As of September 30, 2020, the applicable interest rate was 5.25%. Among other fees, Orion is required to pay an annual facility fee equal to 0.45% of the credit limit under the Credit Agreement, which was paid at commencement (October 26, 2018) and is due on each anniversary thereof. The Credit Agreement requires Orion to maintain nine months’ of “RML” as of the end of each month. For purposes of the Credit Agreement, RML is defined as, as of the applicable determination date, unrestricted cash on deposit with the lender plus availability under the Credit Agreement divided by an amount equal to, for the applicable trailing three-month period, consolidated net profit before tax, plus depreciation expense, amortization expense and stock-based compensation, minus capital lease principal payments, tested as of the end of each month. As of September 30, 2020, Orion was in compliance with this RML requirement. The Credit Agreement also contains customary events of default and other covenants, including certain restrictions on Orion’s ability to incur additional indebtedness, consolidate or merge, enter into acquisitions, pay any dividend or distribution on Orion’s stock, redeem, retire or purchase shares of Orion’s stock, make investments or pledge or transfer assets. If an event of default under the Credit Agreement occurs and is continuing, then the lender may cease making advances under the Credit Agreement and declare any outstanding obligations under the Credit Agreement to be immediately due and payable. In addition, if Orion becomes the subject of voluntary or involuntary proceedings under any bankruptcy or similar law, then any outstanding obligations under the Credit Agreement will automatically become immediately due and payable. Equipment Debt Obligations In June 2015, Orion entered into an agreement with a financing company in the principal amount of $0.4 million to fund the purchase of certain equipment. The debt was secured by the related equipment. The debt incurred interest at a rate of 5.94% and matured in June 2020. In February 2019, Orion entered into additional debt agreements with a financing company in the principal amount of $44 thousand and $30 thousand to fund the purchase of certain equipment. The debts are secured by the related equipment. The debts bear interest at a rate of 6.43% and 8.77%, respectively, and both debts mature in January 2024.

INCOME TAXES

INCOME TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 14 — INCOME TAXES Orion’s income tax provision was determined by applying an estimated annual effective tax rate based upon the facts and circumstances known to book income (loss) before income tax, adjusting for discrete items. Orion’s actual effective tax rate is adjusted each interim period, as appropriate, for changes in facts and circumstances. For the three month period ended September 30, 2020 and 2019, Orion recorded income tax expense (benefit) of $(72) thousand and $19 thousand, respectively, using this methodology. For the six month period ended September 30, 2020 and 2019, Orion recorded income tax expense of $1 thousand and $27 thousand, respectively, using this methodology. As of September 30, 2020 and March 31, 2020, Orion had a full valuation allowance recorded against its deferred tax assets. Orion considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that Orion determines that the deferred tax assets are able to be realized, an adjustment to the valuation allowance would increase income in the period such determination is made. The CARES Act includes significant business tax provisions that, among other things, temporarily eliminate the taxable income limit for certain NOLs, allow businesses to carry back tax year 2018-2020 NOLs to the five prior tax years, accelerate refunds of corporate AMT credits, and generally decrease the amount of disallowed business interest expense. Because of Orion’s loss carryforwards, Orion does not anticipate the income tax provisions of the CARES Act to result in a material cash or financial statement impact during fiscal 2021. Uncertain Tax Positions As of September 30, 2020, Orion’s balance of gross unrecognized tax benefits was approximately $0.3 million, $0.2 million of which would reduce Orion’s effective tax rate if recognized. Orion has classified the amounts recorded for uncertain tax benefits in the balance sheet as Other long-term liabilities to the extent that payment is not anticipated within one year. Orion recognizes penalties and interest related to uncertain tax liabilities in Income tax expense. Penalties and interest are included in the unrecognized tax benefits.

COMMITMENTS AND CONTINGENCIES	NOTE 15 — COMMITMENTS AND CONTINGENCIES Litigation Orion is subject to various claims and legal proceedings arising in the ordinary course of business. Orion does not believe the final resolution of any of such claims or legal proceedings will have a material adverse effect on Orion’s future results of operations or financial condition. State Tax Assessment During fiscal 2018, Orion was notified of a pending sales and use tax audit by the Wisconsin Department of Revenue for the period covering April 1, 2013 through March 31, 2017. Although the final resolution of Orion's sales and use tax audit is uncertain, the ultimate disposition of this matter is not expected to have a material adverse effect on Orion's future results of operations or financial conditions.

Stockholders Equity Note [Abstract]
SHAREHOLDERS' EQUITY	NOTE 16 — SHAREHOLDERS’ EQUITY Shareholder Rights Plan On January 3, 2019, Orion entered into Amendment No. 1 to the Rights Agreement, which amended the Rights Agreement dated as of January 7, 2009 and extended its terms by three years to January 7, 2022. Under the amendment, each common share purchase right (a “Right”), if exercisable, will initially represent the right to purchase from Orion, one share of Orion’s common stock, no par value per share, for a purchase price of $7.00 per share. The Rights will not be exercisable (and will be transferable only with Orion’s common stock) until a “Distribution Date” occurs (or the Rights are earlier redeemed or expire). A Distribution Date generally will occur on the earlier of a public announcement that a person or group of affiliated or associated persons (“Acquiring Person”) has acquired beneficial ownership of 20% or more of Orion’s outstanding common stock (“Shares Acquisition Date”) or 10 business days after the commencement of, or the announcement of an intention to make, a tender offer or exchange offer that would result in any such person or group of persons acquiring such beneficial ownership. If a person becomes an Acquiring Person, holders of Rights (except as otherwise provided in the Rights Agreement) will have the right to receive upon exercise that number of shares of Orion’s common stock having a market value of two times the then-current purchase price, and all Rights beneficially owned by an Acquiring Person, or by certain related parties or transferees, will be null and void. If, after a Shares Acquisition Date, Orion is acquired in a merger or other business combination transaction or 50% or more of its consolidated assets or earning power are sold, proper provision will be made so that each holder of a Right (except as otherwise provided in the Rights Agreement) will thereafter have the right to receive upon exercise that number of shares of the acquiring company’s common stock which at the time of such transaction will have a market value of two times the then-current purchase price. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of Orion. At any time prior to a person becoming an Acquiring Person, the Board of Directors of Orion may redeem the Rights in whole, but not in part, at a price of $0.001 per Right. Unless they are extended or earlier redeemed or exchanged, the Rights will expire on January 7, 2022. Employee Stock Purchase Plan In August 2010, Orion’s Board of Directors approved a non-compensatory employee stock purchase plan, or “ESPP”. In the three months ended September 30, 2020, Orion issued 151 shares under the ESPP plan at a closing market price of $7.57. Shares Issued Under ESPP Plan Closing Market Price Quarter Ended June 30, 2020 458 3.46 Quarter Ended September 30, 2020 151 7.57 Total issued in fiscal 2021 609 $ 3.46 - 7.57

STOCK OPTIONS AND RESTRICTED SHARES	NOTE 17 — STOCK OPTIONS AND RESTRICTED SHARES At Orion’s 2019 annual meeting of shareholders held on August 7, 2019, Orion’s shareholders approved the Orion Energy Systems, Inc. 2016 Omnibus Incentive Plan, as amended and restated (the “Amended 2016 Plan”). Approval of the Amended 2016 Plan increased the number of shares of Orion’s common stock available for issuance under the Amended 2016 Plan from 1,750,000 shares to 3,500,000 shares (an increase of 1,750,000 shares); added a minimum vesting period for all awards granted under the Amended 2016 Plan (with limited exceptions); and added a specific prohibition on the payment of dividends and dividend equivalents on unvested awards. The Amended 2016 Plan authorizes grants of equity-based and incentive cash awards to eligible participants designated by the Plan's administrator. Awards under the Amended 2016 Plan may consist of stock options, stock appreciation rights, performance shares, performance units, common stock, restricted stock, restricted stock units, incentive awards or dividend equivalent units. Prior to the 2016 Omnibus Incentive Plan, Orion maintained its 2004 Stock and Incentive Awards Plan, as amended, which authorized the grant of cash and equity awards to employees (the “2004 Plan”). No new awards are being granted under the 2004 Plan; however, all awards granted under the 2004 Plan that are outstanding will continue to be governed by the 2004 Plan. Forfeited awards originally issued under the 2004 Plan are canceled and are not available for subsequent issuance under the 2004 Plan or under the Amended 2016 Plan. The Amended 2016 Plan and the 2004 Plan also permit accelerated vesting in the event of certain changes of control of Orion as well as under other special circumstances. Certain non-employee directors have from time to time elected to receive stock awards in lieu of cash compensation pursuant to elections made under Orion’s non-employee director compensation program.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of Orion Energy Systems, Inc. and its wholly owned subsidiaries.
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Orion have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2021 or other interim periods. The Condensed Consolidated Balance Sheet at March 31, 2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in Orion’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020 filed with the SEC on June 5, 2020.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, inventory obsolescence and allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes, impairment analyses, and certain equity transactions. Accordingly, actual results could differ from those estimates.
Concentration of Credit Risk and Other Risks and Uncertainties	Concentration of Credit Risk and Other Risks and Uncertainties Orion's cash is deposited with two financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including ballasts, lamps and LED components, from multiple suppliers. For the three months ended September 30, 2020, one supplier accounted for 10.3% of total cost of revenue. For the six months ended September 30, 2020, no supplier accounted for more than 10% of total cost of revenue. For the three months ended September 30, 2019, two suppliers accounted for 17.2% and 10.0% of total cost of revenue, respectively. For the six months ended September 30, 2019, one supplier accounted for 15.5% of total cost of revenue For the three months ended September 30, 2020, one customer accounted for 60.7% of total revenue. For the six months ended September 30, 2020, two customers accounted for 44.4% and 14.9% of total revenue, respectively. For the three months ended September 30, 2019, one customer accounted for 81.1% of total revenue. For the six months ended September 30, 2019, one customer accounted for 79.2% of total revenue. As of September 30, 2020, one customer accounted for 70.9 % of accounts receivable. As of March 31, 2020, two customers accounted for 37.3% and 13.0% of accounts receivable, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued: Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Since the issuance of ASU 2016-13, the FASB released several amendments to improve and clarify the implementation guidance. The provisions of ASU 2016-13 and the related amendments are effective for Orion for fiscal years (and interim reporting periods within those years) beginning after December 15, 2022. Entities are required to apply these changes through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Orion is currently evaluating the impact of adoption of this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general rules of Topic 740. The provisions of ASU 2019-12 are effective for Orion for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Orion is currently evaluating the impact of adoption on this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures.
