Polysilicon PV modules produced by Canadian Solar Inc., a global solar power company, achieved the highest PTC ratings amongst all major poly module manufacturers.

Established by California Energy Commission (CEC), the PVUSA Test Conditions (PTC) ratings program is a universally recognized standard for assessing real-world solar panel performance. In the latest PTC Rating , Canadian Solar's flagship poly solar energy module, the CS6P-P modules (60 cell poly) with 255 Wp, received a PTC Rating of 91.88%, and the CS6X-P modules (72 cell poly) with 305 Wp received a PTC Rating of 91.90%. The higher the PTC power rating, relative to the module's STC power nameplate, the higher the actual on-site solar energy production per watt installed, leading to faster returns on investment.

"The PTC Rating is widely recognized as one of the most realistic, credible measures of PV module output due to its strict definition and calculation criteria and ability to reflect real-world solar and climate conditions,” said Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar Inc. “Consistently ranking at the top of the PTC ratings is added validation and makes the decision to use Canadian Solar modules even easier for customers worldwide, when combined with our leading global brand, bankability, scale and industry leading balance sheet."
