Suntech Power, one of the world’s largest solar module manufacturers, has extended the product warranty period for its photovoltaic modules as it exhibited confidence in product quality and strengthened after-sale service.

The new warranty policy took effect on January 1, 2016. All modules made by Suntech are now under a 12-year product warranty, extending from the previous 10-year period. Customers of Suntech, benefiting from the extended warranty period, are exempt from paying warranty fees for the extra 2 years.

While most products offered by other brands are covered under a 10 year product warranty, the extension made Suntech one of the few solar module manufacturers around the world, whose products are provided with a 12 year warranty.

“Quality is the key to our success, and Suntech hopes to send a strong message to our customers and the market: We are highly confident of the product quality and we will continue to strengthen our after-sale service,” said Tang Jun, president of Wuxi Suntech Power. “The decision to extend the product warranty period is a result from our commitments to better serving our customers and we will spare no efforts to deliver the best products and services to our customers.”
