Canadian Solar Expands Product Warranty On PV Modules


Canadian Solar Inc. says it has introduced a new product and performance warranty for its solar modules. Effective Aug. 1, the warranty now provides a linear performance guarantee for the PV module power output over a 25-year period.

Under the terms of the new performance warranty, Canadian Solar guarantees that the actual power output of its modules will be no less than 97% of the labeled power output during the first year of operation, and will decline by no more than 0.7% annually; thus, by the end of year 25 the actual power output will be no less than 80% of the module's labeled power output.

In addition, under this new policy, Canadian Solar has expanded its product warranty covering workmanship and material defects to 10 years. The warranty will continue to be backed by a 25-year, non-cancelable insurance policy issued by A.M. Best-rated, investment-grade insurance underwriters, the company notes.
