JA Solar Closes Concurrent Offerings of $400 Million of Senior Convertible Notes
and Up to 13,125,520 Borrowed American Depositary Shares

JA Solar Holdings Co., Ltd. ("JA Solar") (Nasdaq:JASO) today announced the
closings on May 19, 2008 of its public offerings of $400 million aggregate
principal amount of senior convertible notes due 2013 and up to 13,125,520
American depositary shares, or ADSs, which ADSs were borrowed by affiliates of
the joint book-running managers of the notes offering pursuant to ADS lending
agreements with JA Solar. The notes sold include $50 million aggregate principal
amount of notes issued pursuant to the underwriters' exercise in full of their
option to purchase additional notes.

The notes will pay interest semi-annually at the annual rate of 4.50%, and
mature on May 15, 2013. Prior to February 15, 2013, the notes will be
convertible upon specified events and, thereafter, at any time, based on an
initial conversion rate of 32.8138 ADSs per $1,000 principal amount of notes,
which represents an initial conversion price of approximately $30.475 per ADS.
The initial conversion rate, and thus the initial conversion price, will be
subject to adjustment under certain circumstances. Upon conversion, JA Solar
will have the right to deliver (i) ADSs or (ii) cash and, if applicable, ADSs.
JA Solar currently intends to satisfy its conversion obligation upon any
conversion of notes by delivering cash, and, if applicable, ADSs.

Holders of the notes may require JA Solar to repurchase the notes upon certain
fundamental changes. On or after May 15, 2011, JA Solar may redeem all or a
portion of the notes if the closing sale price of its ADSs has been at least
130% of the then applicable conversion price for at least 20 trading days during
any period of 30 consecutive trading days, including the last trading day of
such period, ending on the trading day preceding the date on which JA Solar
provides notice of redemption.

JA Solar intends to use the net proceeds of the notes offering for the purchase
and construction of manufacturing equipment and facilities, the purchase and
prepayment of raw materials, working capital and other general corporate
purposes.

In connection with the notes offering, JA Solar has entered into capped call
transactions with financial institutions that are affiliates of the joint
book-running managers of the notes offering (the "counterparties"). Pursuant to
the capped call transactions, JA Solar purchased capped call options from the
counterparties with a strike price equal to the conversion price of the notes
and a cap price of $37.375 per ADS, which is 62.5% higher than the offer price
of the borrowed ADSs initially offered by the concurrent offering. The capped
call transactions are expected to reduce the potential dilution upon conversion
of the notes.

In connection with hedging the capped call transactions, JA Solar has been
advised by the counterparties that they or their affiliates expect to enter into
various over-the-counter cash settled derivative transactions with respect to
the ADSs concurrently with or shortly after the pricing of the notes and to
purchase ADSs in secondary market transactions shortly after the pricing of the
notes. These activities could have the effect of increasing or preventing a
decline in the price of the ADSs or the notes concurrently with or following the
pricing of the notes. In addition, JA Solar has been advised by the
counterparties that they or their affiliates expect to modify or unwind their
hedge positions by purchasing or selling ADSs in secondary market transactions
and/or entering into or unwinding various derivative transactions prior to
maturity of the notes (including during any conversion period related to the
conversion of the notes). These activities could have the effect of increasing,
preventing a decline in or adversely impacting the price of the ADSs or the
notes.

In connection with the notes offering and the entry into the capped call
transactions, JA Solar entered into ADS lending agreements with affiliates of
the joint-book running managers of the notes offering (the "ADS borrowers"),
pursuant to which JA Solar on May 19, 2008 loaned 13,125,520 ADSs to the ADS
borrowers. Concurrently with the offering of notes, the ADS borrowers sold
borrowed ADSs pursuant to a separate prospectus supplement (the "ADS prospectus
supplement"). 6,590,312 of the borrowed ADSs were sold on May 19, 2008 at $23.00
per ADS and the remaining borrowed ADSs will be subsequently sold at prevailing
market prices at the time of sale or at negotiated prices.

The ADS borrowers will receive all of the proceeds from the sale of the borrowed
ADSs. JA Solar will not receive any of the proceeds from the sale of the
borrowed ADSs, but received a nominal lending fee for the use of the borrowed
ADSs. The sale of the borrowed ADSs is intended to facilitate privately
negotiated transactions or short sales by which investors in the notes will
hedge their investment in the notes and/or by which the counterparties will
hedge the capped call transactions.

While the borrowed ADSs will be considered issued and outstanding for corporate
law purposes, JA Solar believes that under U.S. GAAP currently in effect, the
borrowed ADSs will not be considered outstanding for the purpose of computing
and reporting earnings per ADS because the ADSs borrowed pursuant to the ADS
lending agreements are required to be returned to JA Solar by May 15, 2013.

Lehman Brothers Inc. and Credit Suisse Securities (USA) LLC acted as joint
book-running managers for the notes offering and the ADS offering, and Needham &
Company, LLC and Piper Jaffray & Co. served as co-managers for the notes
offering.

The concurrent offerings were made under JA Solar's shelf registration statement
filed with the Securities and Exchange Commission on May 12, 2008. This press
release does not constitute an offer to sell, or the solicitation of an offer to
buy, securities, and does not constitute an offer, solicitation or sale in any
