PV module manufacturer Senersun says it has upgraded its power output warranty to a linear performance warranty.
Under the new warranty, Senersun guarantees that its solar panels will produce at least 97% of the rated power output during the first year. For the following 25 years, Senersun guarantees that its panels' power will not decrease by more than 0.7% of the rated power per year.
The new warranty applies to all Senersun products delivered to customers from Aug. 1, 2012, onward and produced after July 21, 2012.
