Canadian Solar Modules Continue to Be Recognized for Top PV USA Ratings

CS6P-230P Module Leads the Ratings for Highest Quality and Efficiency
ONTARIO, Canada, Feb 11, 2010 /PRNewswire via COMTEX/ -- Canadian Solar Inc. ("the Company," "Canadian Solar" or "we") (Nasdaq: CSIQ) today announced that five of its solar module series, CS6P- 220P, 225P, 230P, CS5P-240M and CS5A- 180M, rank amongst the highest performing in last month's PV USA (PTC) ratings. PTC ratings are quickly becoming universally accepted standards for measuring real-world module power and performance.

"Canadian Solar is pleased to have received some of the industry's highest PTC rankings for our high-quality solar products. Canadian Solar modules power critical energy projects around the world, and are selected for their efficiency and long-term reliability," said Dr. Shawn Qu, Chairman and CEO of Canadian Solar. "The PTC rankings validate what our partners and customers have come to know -- that Canadian Solar modules are amongst the best performing modules in real-world conditions."

The PTC measurement, a mandatory test in the State of California, measures a PV system's power output at atmospheric conditions that closely resemble true solar and climatic variable conditions. A higher PV rating indicates higher actual production on-site per-watt installed, which translates directly into higher rebates for system owners.

About Canadian Solar High Power CS Series

The Canadian Solar CS series leads the industry in PV USA testing. According to CEC listing data(1), Canadian Solar ranks amongst industry's highest per Watt PTC ratings (CS6P-230P for 91.74%, CS6P-225P for 91.69%, CS6P-220P for 91.64%, and CS5P-240M for 91.13% and CS5A-180M for 91.11%) among key module manufacturers with mainstream P-type silicon technology. PTC ratings more closely simulate real-world solar and climatic conditions than Standard Test Condition (STC) ratings for a more accurate indication of performance and a PV system's power output. All ratings in the list are in DC (direct current) watts.
