Canadian Solar Receives QC 080000 Hazardous Materials Management Certification

August 20, 2007

    JIANGSU, China, Aug. 20 /Xinhua-PRNewswire/ -- Canadian
Solar Inc. ("the Company", or "CSI", or
"we") (Nasdaq: CSIQ) today announced that its
Changshu factory has completed its audit for the QC 080000
IECQ Hazardous Substance Process Management (HSPM)
qualification, which the Company believes makes it one of
the first solar module manufacturing companies to receive
the certification.    
    QC 080000 IECQ HSPM is the international technical
specification for an organization's processes to manage and
minimize, or eliminate hazardous substances. The
qualification confirms that CSI has a process-oriented
quality management system (QMS) in place, compliant with
ISO 9001:2000.  The distinguished qualification carries
with it the potential for reduced testing and supplier
management costs, and the reduced risk of violating laws in
a changing regulatory landscape.
    The audit was conducted by the internationally
recognized certification body TUV, a leading international
safety testing and certification services company.
    Meanwhile, CSI's newly built solar cell factory in
Suzhou and its recently built module factory in Luoyang has
passed ISO 9001:2000 certification audits by TUV last week.
As a result, all of CSI production facilities are now
certified to ISO 9001:2000 standard.
    Dr. Shawn Qu, Chairman and CEO of CSI, said, "The
qualification demonstrates CSI's high standard and industry
leadership on product safety. It also demonstrates our
technical competence and operational skill with regards to
the ability to manufacture high quality products, while
maintaining our devotion to environmentally friendly
manufacturing processes.  We are fully prepared to move
into lead-free module production if required to by
regulatory bodies, which further highlights the ability of
CSI's management team to respond to changes in the
regulatory landscape for renewable energy.  This
recognition of our operational efficiency and integrity
will further bolster our global reputation, and will help
raise our profile with potential new customers."
