TORONTO and GUELPH, Canada, Dec. 28, 2012 /PRNewswire-FirstCall/ --Canadian
Solar Inc. (the "Company", or "Canadian Solar")(NASDAQ: CSIQ), one of the
world's largest solar companies, and SunEdison Power Canada Inc.
("SunEdison"), a subsidiary of MEMC Electronic Materials, Inc., today
announced that they have completed a purchase and sale transaction wherein
Canadian Solar's direct subsidiary Canadian Solar Solutions Inc. has acquired
a majority interest in two utility-scale solar power projects in Ontario with
a total capacity of approximately 24 MW DC. Subject to certain contractual
conditions, Canadian Solar has the ability to complete a purchase of two
additional utility-scale solar power projects in Ontario with a total capacity
of approximately 22.5 MW DC, and an option to purchase a fifth solar project
at a later date from SunEdison. Each of the five solar power projects was
awarded a 20-year power purchase contract (a "FIT Contract") by the Ontario
Power Authority under Ontario's Feed-In-Tariff Program (FIT version 1.0). The
two projects purchased have each received Renewal Energy Approvals and are
expected to commence construction in early 2013 and be fully operational by
late 2013. The remaining solar energy projects are in the advanced permitting
stage and are expected to commence construction in early to mid-2013 and be
fully operational by late 2013 and early 2014.

The aggregate transaction price is approximately C$37 million (US$ 38 million)
payable in accordance with certain milestones. The completion of the
transaction also brings a settlement to litigation proceedings between
Canadian Solar and SunEdison commenced in the Ontario courts in October 2011.

"We are very pleased to announce this transaction with SunEdison which further
demonstrates Canadian Solar's ongoing investment and commitment to the Ontario
solar energy market, and continues Canadian Solar's growth of its global solar
project portfolio and higher margin total solutions business," said Dr. Shawn
Qu, Chairman and Chief Executive Officer at Canadian Solar. "Each of these
four solar projects will create and sustain green jobs in Ontario and will
generate clean, renewable energy for decades to come."
