Excludes 4,534,756 ordinary shares issuable upon the exercise of options outstanding, 1,569,636 issued but unvested restricted shares and 1,084,842 ordinary shares reserved for future issuance under our 2006 stock incentive plan as of March 31, 2009.

Includes a restricted reserve of RMB145.0 million, which may not be distributed as cash dividends under PRC regulations.

     In January 2009, Yingli China entered into a credit agreement with ADM Capital, which provided Yingli China with a three-year loan facility of US$50.0 million. The loan facility was drawn down in full in April 2009. As of the date of this prospectus supplement, we had approximately RMB 341.1 million (US$50 million) outstanding under the loan facility.

     In June 2009, we issued 2,000,000 ordinary shares to Trustbridge in exchange for the conversion of approximately US$8.7 million of our outstanding senior secured convertible notes.

     Renminbi amounts in this “Capitalization” section have been translated into U.S. dollar amounts at the rate of RMB 6.8329 to US$1.00, the noon buying rate in New York for cable transfers of Renminbi per U.S. dollar as set forth in the H.10 weekly statistical release of the Federal Reserve Board, as of March 31, 2009. No representation is intended to imply that the Renminbi amounts could have been, or could be, converted, realized or settled into U.S. dollar amounts at such rate, or at any other rate.

DILUTION

     The “Dilution” section on page S-22 of the Preliminary Prospectus Supplement is being amended as follows:

     If you invest in our ADSs, your interest will be diluted to the extent of the difference between the public offering price per ADS and our net tangible book value per ADS after this offering. Dilution results from the fact that the public offering price per ordinary share is substantially in excess of the book value per ordinary share attributable to the existing shareholders for our presently outstanding ordinary shares.

     Our net tangible book value as of March 31, 2009 was approximately RMB 3,995.2 million (US$584.7 million) or RMB 31.23 (US$4.57) per ordinary share and per ADS. Net tangible book value represents our total consolidated assets, minus the amount of our total consolidated intangible assets, total consolidated liabilities and noncontrolling interests. Our net tangible book value per share as of March 31, 2009 is calculated as our net tangible book value as of March 31, 2009, without taking into account any other changes in such net tangible book value after March 31, 2009 divided by the number of ordinary shares outstanding at March 31, 2009.

     Without taking into account any other changes in such net tangible book value after March 31, 2009 except for the issuance and sale of ordinary shares in the form of ADSs offered by us in this offering, at the assumed public offering price of US$13.76 per ADS, based on the last trading price of our ADSs on June 12, 2009, and after deduction of underwriting discount and estimated aggregate offering expenses of this offering payable by us, our pro forma net tangible book value as of March 31, 2009 would have increased to US$747.8 million or US$5.32

per ordinary share and per ADS, assuming no exercise of the underwriters’ over-allotment option to purchase additional ADSs from us. This represents an immediate increase in net tangible book value of US$0.75 per ordinary share and per ADS to the existing shareholder and an immediate dilution in net tangible book value of US$8.44 per ordinary share and per ADS to investors purchasing ADSs in this offering.

     The following table illustrates such per share dilution:

Assumed Public Offering Price per Ordinary Share		US$
Net tangible book value per ordinary share as of March 31, 2009		US$4.57
Increase in net tangible book value per ordinary share attributable to this offering		US$0.75
Net tangible book value per ordinary share after giving effect to this offering		US$5.32
Dilution per ordinary share to new investors		US$8.44
Dilution per ADS to new investors		US$8.44

     A US$1.00 increase (decrease) in the assumed public offering price of US$13.76 per ADS would increase (decrease) our pro forma net tangible book value after giving effect to this offering by US$0.09 per ordinary share and per ADS and the dilution in pro forma net tangible book value per ordinary share and per ADS to new investors in this offering by US$0.91 per ordinary share and per ADS, assuming no exercise of the underwriters’ over-allotment option to purchase additional ADSs from us.

     The following table summarizes, on a pro forma basis as of March 31, 2009, the differences between existing shareholders and the new investors with respect to the number of ordinary shares in the form of ADSs purchased from us, the total consideration paid and the average price per ordinary share and per ADS. In the case of the ordinary shares purchased by the new investors, the total consideration paid and amounts per share paid are before deducting underwriting discount and estimated aggregate offering expenses, assuming a public offering price of US$13.76 per ADS, based on the last trading price of our ADSs on June 12, 2009, assuming no exercise of the underwriters’ over-allotment option to purchase additional ADSs from us.

     The discussion and table above excludes unvested restricted shares and also assumes no exercise of any outstanding options under the 2006 stock incentive plan. As of the date of this prospectus supplement, we have granted 4,829,213 options and 2,621,060 restricted shares.

     A US$1.00 increase (decrease) in the assumed public offering price of US$1.00 per ADS would increase (decrease) total consideration paid by new investors, total consideration paid by all shareholders and the average price per ADS paid by all shareholders by US$12.5 million, US$12.5 million and US$0.09, respectively, assuming no exercise of the underwriter’s over-allotment option to purchase additional ADS from us.

     The pro forma information in this section is illustrative only. Our net tangible book value following the completion of this offering is subject to adjustment based on the actual public offering price of our ADSs.

     Renminbi amounts in this “Dilution” section have been translated into U.S. dollar amounts at the rate of RMB 6.8329 to US$1.00, the noon buying rate in New York for cable transfers of Renminbi per U.S. dollar as set forth in the H.10 weekly statistical release of the Federal Reserve Board, as of March 31, 2009. No representation is intended to imply that the Renminbi amounts could have been, or could be, converted, realized or settled into U.S. dollar amounts at such rate, or at any other rate.
