	The condensed consolidated balance sheet, financial information and related disclosures as of December 31, 2012 have been derived from our consolidated financial statements, which have been audited as of that date. The condensed consolidated balance sheet as of September 29, 2013 and the related condensed consolidated statements of operations and comprehensive loss for the three and nine months ended September 29, 2013 and September 30, 2012 are unaudited. The condensed consolidated statement of stockholders’ equity and consolidated statements of cash flows for the nine months ended September 29, 2013 and September 30, 2012 are unaudited. In the opinion of management, all adjustments necessary for the fair presentation of such financial statements have been included. Such adjustments consisted only of normal recurring items. Interim results are not necessarily indicative of results for any other period or for the full year. These financial statements do not include all disclosures associated with annual financial statements and, accordingly, should be read in conjunction with the footnotes contained in the Company’s consolidated financial statements as of and for the year ended December 31, 2012, together with the auditors’ report, included in the Company’s Annual Report on
	Form 10-K, as filed with the Securities and Exchange Commission (SEC).

	(2) Summary of Significant Accounting Policies
	The accounting policies underlying the accompanying unaudited condensed consolidated financial statements are those set forth in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the SEC.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, that requires entities to disclose items reclassified out of Accumulated Other Comprehensive Income (AOCI) and into net income in their entirety, the effect of the reclassification on each affected net income line item and for AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This consolidated standard is effective for annual periods beginning after December 15, 2012 and interim periods within those years. The application of this standard did not have a material impact on the Company’s consolidated financial statements.
	Subsequent Events - The Company evaluated subsequent events through the time of issuance of these condensed consolidated financial statements. On October 4, 2013, the Company settled previously disclosed litigation regarding allegations made by one of its overseas customers that furnaces such customer had purchased from the Company in 2006 had not functioned properly. The settlement constitutes a full and final settlement and release of all rights and obligations of each party. The $1.5 million payable as a result of the settlement has been recognized in the Company’s consolidated statement of operations for the three months ended September 29, 2013.
	We are not aware of any other events that occurred subsequent to the balance sheet date, but prior to the filing of this report that would have a material impact on the Company’s condensed consolidated financial statements.

	Warranty
	The Company provides standard warranty coverage for labor for 12 months and special extended material-only coverage on certain products. The Company estimates and records an accrual for anticipated warranty claims based on sales. The accrual for warranty claims covers the estimated costs of material, labor and travel. Actual warranty claims incurred are charged to the accrual. Factors that affect the Company’s product warranty accrual include the number of installed units, the anticipated cost of warranty repairs and historical and anticipated rates of warranty claims.
	The following table reflects changes in the Company’s accrued warranty account during the nine months ended September 29, 2013 (in thousands):

	Restructuring
	In April 2013, the Company eliminated 12 positions. Accordingly, the Company recorded a restructuring charge of $176,000 in the three months ended June 30, 2013. The decision to eliminate 12 positions was taken due to the continued slowdown in the solar industry. The Company eliminated 31 positions and recorded restructuring charges of $424,000 in the year ended December 31, 2012.

On September 9, 2010, the Company signed a First Loan Modification Agreement relating to the mortgage note, which reduced the annual interest rate from 6.84% to 5.50% and the monthly payment from $76,280 to $69,000.
	On September 26, 2013, the Company signed a Second Loan Modification Agreement relating to the mortgage note, which extended the maturity date from December 23, 2015 to September 26, 2023. The modification also reduced the annual interest rate from 5.50% to 4.43% through September 26, 2018, at which time the interest rate will be adjusted to a per annum fixed rate equal to the aggregate of the FHLB Five Year Classic Advance Rate plus two hundred forty basis points. The current monthly payment was reduced from $69,000 to $57,997. All outstanding principal and accrued and unpaid interest will be due and payable on the maturity date.
	On August 31, 2009, the Company entered into a pledge and assignment agreement with a bank. The bank agrees, at the Company’s request, to issue letters of credit in the bank’s name and the Company agrees to cash collateralize letters of credit via restricted cash deposits at the bank. As of September 29, 2013, the value of the outstanding letters of credit issued by the bank for the Company and cash collateralized by the Company was $252,566. This restricted cash value is included in the Company’s balance sheet in other current assets.

Earnings Per Share [Abstract]	'
Net Loss Per Share	'
	(6) Net Loss Per Share
	Basic EPS is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed using the weighted-average number of common shares and potentially dilutive securities outstanding during the period, using the treasury stock method. Potentially dilutive securities include outstanding stock options and unvested restricted stock units. Due to their anti-dilutive effect, approximately 1,315,670 and 1,291,326 options to purchase common stock were excluded from the calculation of diluted loss per share for the nine months ended September 29, 2013 and September 30, 2012, respectively. However, these potentially dilutive securities could become dilutive in future periods.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]	'

	(7) Accounting for Stock-Based Compensation
	Stock Options
	The Company’s stock option compensation expense was $140,027 and $436,984 for the three and nine months ended September 29, 2013, respectively, and $180,321 and $678,577 for the three and nine months ended September 30, 2012, respectively. These amounts do not include expense related to restricted stock awards or the employee stock purchase plan.
	The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free market interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The Company is also required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data is used to estimate pre- vesting forfeitures and record stock-based compensation expense only for those awards that are expected to vest. Accordingly, awards ultimately expected to vest have been reduced by an annualized estimated forfeiture rate of 4%.
	Calculation of Fair Value - Assumptions Used:
		Nine months ended
		September 29, 2013			September 30, 2012
	Expected Volatility		66.84	%		66.85	%
	Expected Life (in years)		4.21			4.21
	Risk-Free Interest Rate		0.79	%		0.59	%
	Expected Dividend Yield		—			—
	Expected volatilities are based on the historical volatility of the Company’s common stock. The Company used significant historical data to help evaluate the expected lives of options in developing its assumption. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities with a term approximating the expected life of the options. The expected dividend yield is based upon the Company’s long-standing history of not issuing dividends and management’s current expectation of the same.
	The following table summarizes the stock option activity during the nine months ended September 29, 2013:
		Shares			Weighted-			Average		Aggregate
					Average			Remaining		Intrinsic
					Exercise			Contractual		Value
					Price			Term
	Options

	Exercisable at September 29, 2013		862,852		$	6.29			2.7	$	5,543
	The weighted-average grant date fair values of options granted during the nine-month periods ended September 29, 2013 and September 30, 2012 were $1.21 and $1.54, respectively. The aggregate fair values of options exercised during the nine-month periods ended September 29, 2013 and September 30, 2012 were $0 and $6,179, respectively.
	As of September 29, 2013, there was $622,685 of total unrecognized compensation cost related to non-vested options granted under the Company’s option plans. That cost is expected to be recognized over a weighted-average period of 1.43 years. The total fair value of options vested during the nine-month period ended September 29, 2013 was $326,401.
	Restricted Stock Units
	In June 2013, the Company granted 20,250 restricted stock units to various employees. The fair value of the restricted stock units at the date of the grant was $2.35. These stock units vest over a two-year term. The Company has recorded compensation expense of $27,913 and $4,633 during the nine-month period ended September 29, 2013 and September 30, 2012, respectively, related to restricted stock units. As of September 29, 2013, there was $60,610 of unrecognized compensation costs related to these grants. These grants have a remaining life of 1.38 years.

	(9) Fair Value of Financial Instruments
	In accordance with the requirements of the Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification (ASC), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
		•	Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.
		•	Level 2 - Valuation is based on quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
		•	Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.
	In accordance with the requirements of the Fair Value Measurements and Disclosures Topic of the FASB ASC, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, the Company uses quoted market prices to measure fair value. If market prices are not available, the fair value measurement is based on models that use primarily market based parameters including interest rate yield curves, option volatilities and currency rates. In certain cases, where market rate assumptions are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. Changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.
	The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short-term nature. Long-term debt is also reported at carrying value and approximates fair value as the interest rate on the mortgage note payable of 4.43% approximates the current market interest rate.

	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, that requires entities to disclose items reclassified out of Accumulated Other Comprehensive Income (AOCI) and into net income in their entirety, the effect of the reclassification on each affected net income line item and for AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This consolidated standard is effective for annual periods beginning after December 15, 2012 and interim periods within those years. The application of this standard did not have a material impact on the Company’s consolidated financial statements.
Subsequent Events	'
	Subsequent Events - The Company evaluated subsequent events through the time of issuance of these condensed consolidated financial statements. On October 4, 2013, the Company settled previously disclosed litigation regarding allegations made by one of its overseas customers that furnaces such customer had purchased from the Company in 2006 had not functioned properly. The settlement constitutes a full and final settlement and release of all rights and obligations of each party. The $1.5 million payable as a result of the settlement has been recognized in the Company’s consolidated statement of operations for the three months ended September 29, 2013.
	We are not aware of any other events that occurred subsequent to the balance sheet date, but prior to the filing of this report that would have a material impact on the Company’s condensed consolidated financial statements.
