Canadian Solar and China's Luoyang Polysilicon Company Complete the First BIPV Solar Glass Roof System in Henan Province

October 02, 2007

    JIANGSU, China, Oct. 1 /Xinhua-PRNewswire/ -- Canadian
Solar Inc. ("the Company," "CSI," or
"we") (Nasdaq: CSIQ) today announced that it has
completed the first BIPV solar glass roof system, with
glass-on-glass solar modules, in Henan Province in
collaboration with China's Luoyang Polysilicon Company. CSI
was the sole supplier of the solar glass technology, the
specialty BIPV modules, and acted as the integrator of the
complete solar power system.  

    The BIPV solar glass system, covering approximately 293
square meters of roof space, was installed on the
three-story building in Luoyang of Henan Province, which
houses the Research Department of Luoyang Polysilicon and
the China National Silicon Materials Engineering Research
Center. This research center facility is designed and built
by ENFI engineering group, a leading design institute for
polysilicon production plants and the majority owner of
Luoyang Polysilicon, currently the largest polysilicon
manufacturer in China. The project was financially
sponsored by the Technology Development Fund of Luoyang
Municipality Government.  

    In August 2007, China's National Development &
Reform Commission (NDRC) published its national development
strategy for renewable energy. According to this strategy,
China targets to install 300 MW cumulative solar generation
capacity by 2010 and 1.8 GW by 2020. 

    Mr. Guohong He, Deputy General Manager of China Luoyang
Polysilicon commented: "CSI is a world class PV module
maker and lived up to its reputation as a leader in
specialty solar module products.  We are pleased with the
superior workmanship CSI demonstrated in the BIPV solar
glass roof system. The project has successfully passed our
performance tests. We look forward to opportunities to
collaborate with CSI in many other areas of solar
applications, given the recent announcement by China's
National Development & Reform Commission (NDRC) of its
national development strategy for renewable energy.  We are
confident that China will be a major solar power market in
the near future."

    Dr. Shawn Qu, Chairman and CEO of Canadian Solar Inc.
commented: "BIPV combines solar technology with
architecture, which is a fast growing area of solar
applications. This is a perfect area for us given CSI's
years of experience in specialty solar modules and
customized solar system design.  We are able to take an
unusable space and transform it into an environmentally
friendly, energy generating, cost saving structure.  The
completion of this project marks one of many potential
high-profile, showcase projects, which the two companies
expect to pursue together."
