RE:   SOLARFUN POWER HOLDINGS CO., LTD.
      REGISTRATION STATEMENT ON FORM F-1
      FILED ON DECEMBER 11, 2006
      FILE NO. 333-139258

Dear Messrs. Mumford and Hindin:

     Solarfun Power Holdings Co., Ltd. (the "Company") has requested us to
respond to the Staff's comment letter, dated December 18, 2006, relating to the
Company's registration statement on Form F-1 publicly filed on December 11, 2006
(the "Registration Statement") File No. 333-139258. In addition, the Company is
publicly filing today Amendment No. 1 to the Registration Statement, which
consists primarily of a revised Exhibit 4.2 (specimen ordinary share
certificate) and Exhibit 5.1 (Cayman Islands counsel opinion). The revised pages
of Amendment No. 1 to the Registration Statement (including the revised
exhibits) are attached hereto as Annex A for the Staff's reference.

                                                               December 18, 2006

     The Company's responses to the Staff's comments are set forth below. The
numbered paragraphs below correspond to the numbered paragraphs of the Staff's
comment letter, which have been retyped herein in bold for your ease of
reference.


EXHIBIT 5.1

1.   WE NOTE YOU RESPONSE TO COMMENT 12; HOWEVER, PARAGRAPH (III) AND THE
     FOLLOWING LANGUAGE FROM THE NEXT PARAGRAPH, "... AND WE HAVE ASSUMED THAT
     THERE IS NOTHING UNDER ANY OTHER LAW THAT WOULD AFFECT OR VARY THE
     FOLLOWING OPINIONS" IMPLIES THAT YOU HAVE NOT YET FILED AN OPINION THAT
     ADDRESSES ALL LEGAL ISSUES UNDERLYING THE QUESTION OF WHETHER THE SHARES
     BEING OFFERED ARE LEGALLY ISSUED, FULLY PAID AND NON-ASSESSABLE. PLEASE
     FILE AN OPINION FROM APPROPRIATE COUNSEL THAT ADDRESSES THE LEGAL QUESTIONS
     CARVED OUT BY THIS LANGUAGE.

     The language cited by the Staff in the comment above has been deleted from
     Exhibit 5.1, as requested. See the revised Exhibit 5.1 being filed on the
     date hereof as an exhibit to Amendment No. 1 to the Registration Statement
     on Form F-1. See also Annex A hereto.

2.   WE NOTE YOUR RESPONSE TO COMMENT 13. AT WHAT POINT IN TIME IS THE ENTRY
     MADE? CAN IT BE MADE BEFORE EFFECTIVENESS OF THE REGISTRATION STATEMENT? IF
     SO, PLEASE DO SO AND DELETE THE CONDITION IN THE LEGALITY OPINION.

     Maples and Calder can only update the register of members to show the
     Ordinary Shares have been issued on December 26, 2006 (the Closing Date).
     This is because the commercially agreed terms of this transaction are that
     the Ordinary Shares are being issued as fully-paid and non-assessable,
     which means that the subscribers for the Ordinary Shares are only entitled
     to those shares if the Company has first been paid the issue price for the
     Ordinary Shares in full.

     Cayman Islands law requires the Company to maintain a register of members
     containing (amongst other things) the names and addresses of each
     shareholder and the date on which the name of any person was entered on (or
     removed from) such register. Cayman Islands law also permits a person whose
     name is, without sufficient cause, entered in or omitted from such
     register, to apply to a Cayman Islands court to apply for that register to
     be rectified. The Cayman Islands court has power, if satisfied of the
     justice of the particular case, to compel the Company to pay all of the
     costs of and any damages to, a party who has suffered loss as a result of
     any improper entry or omission of entry in a company's register of members.

     A subscriber for shares is only entitled to have his/her name entered on a
     register of members if he/she has performed his/her side of the bargain and
     done all things agreed

                                                               December 18, 2006

     with a company in respect of a share issue. On this particular transaction,
     that means payment in full in advance on the date that has been agreed as
     the date of Closing - i.e., December 26, 2006.

     A Cayman Islands company may issue shares as partly-paid or as nil-paid, in
     which case the person who subscribed for such shares on such terms is
     entitled to have his/her name entered on the register as the legal owner of
     such shares; in such circumstances however, the registered holder of the
     shares remains liable to the Company to pay to the Company from time to
     time, amounts that remain unpaid in respect of such shares.

     It has not been agreed in this transaction that the Ordinary Shares are to
     be issued as partly-paid or as nil-paid however, and so it would not be
     permissible to enter a person's name on the Company's register of members
     as the owner of shares if payment for the Ordinary Shares had only been
     made in part.

     On December 26, 2006, when the Company confirms that it has received
     payment in full for the Ordinary Shares, Maples and Calder will be
     authorized by the Company to update the Company' register of members to
     show that these Ordinary Shares have been issued.
