Optimized balance of system value for utility and commercial customers

CHICAGO, Oct. 21, 2013 -- Suntech Power Holdings Co., Ltd. (NYSE: STP), ("Suntech" or the "Company"), one of the world's largest solar companies, will showcase its 1,500V frameless photovoltaic module at the Solar Power International (SPI) Exhibition in Chicago, Illinois. This higher voltage module, engineered for utility-scale and commercial applications, lowers balance of system costs. Suntech's 1,500V frameless PV module will be on display at booth #243.

The 60-cell IEC-rated 1,500Vdc module achieves lower balance of system costs by allowing longer cable runs and longer strings, fewer combiner boxes and smaller wire sizes. Because there is no frame around the modules, equipment grounding is not required. Labor and materials are reduced, saving money for the installer and for the customer.

The frameless construction is a "glass-on-glass" structure which replaces the backsheet with heat-strengthened glass. Its IP67-rated junction box greatly reduces the possibility of water or dirt ingress. Eliminating the frame removes a key mechanism for Potential Induced Degradation (PID). The new module is backed by the Company's 25-year linear power warranty.

Aesthetically, the glass-only module presents a clean look. Its low profile is only 6mm thick. Effective wire management with no grounding lugs contributes to the sleek aesthetics as well.

"Suntech continues its commitment to develop solutions to better meet the requirements of our customers throughout the value chain," said Mick McDaniel, Managing Director of Suntech America. "This new higher voltage module incorporates the most recent advances in solar technology to enable our partners to install ever more efficient and durable utility and commercial power plants."

The introduction of this new module extends the Suntech portfolio of photovoltaic products. The new 1500V frameless 255W (STP255-20/Wdj) and 250W (STP250-20/Wdj) modules will be available for installation beginning in the first quarter of 2014.
