Trina Solar has updated its warranties in regards to product quality and performance. The PV module manufacturer said that products delivered from June 20, 2011, will include product workmanship warranty of ten years and a shift to a new 25-year linear performance warranty guarantee that module power output would not decrease by more than approximately 0.7% per year after the initial year of service.
The warranty updates are in-line with some of the major European PV module manufacturer’s warranties. Previously, Trina offered a standard 5-year product quality warranty and a two-step performance warranty. The new warranties apply to Trina Solar's entire product offering portfolio, including both monocrystalline and multicrystalline modules.
“We are proud to take a leadership position to extend our workmanship warranty and provide a linear power performance assurance,” commented Mark Kingsley, Trina Solar's Chief Commercial Officer. “This improvement will allow us to work closer with our customers and large scale utility projects by allowing better estimates of power output throughout the system life. This development is based on our confidence and history of quality manufacturing and reflects our commitment to continuous innovation to lower the cost of solar provided power through higher cell and module efficiencies, timing saving installation, and system performance.”
