NANJING, China, August 30, 2011 -- ET Solar Group Corp. ("ET Solar"), a China-based vertically integrated producer and provider of solar modules and related PV solutions to the global solar market, today announces linear power performance warranty for its solar module products.

ET Solar 25-year linear power performance warranty guarantees no less than 97% of the nominal power output in the first year and then a maximum annual output degradation of 0.65% thereafter. By the end of the 25th year, the actual power output will be no less than 81.4% of the nominal power output. This warranty applies to both mono and multi-crystalline modules of ET Solar.

Dennis Shaw, Chief Executive Officer of ET Solar, commented, “The linear power performance warranty is a result of our continuous R&D and quality control efforts. This new warranty program, together with the 10-year workmanship warranty program that we launched in this May for our module products, will provide stronger assurance to our customers on quality of our modules and the financial returns they bring.”
