Suntech Introduces New High-Efficiency 250W BlackPearl™ Module

The BlackPearl™ 250W product is a 60 cell module comprised of 6-inch black square cells that delivers one of the highest power per weight ratios in the industry. The module features a +0 to +5% positive power tolerance and exceptionally low oxygen content leading to strong resistance to light-induced degradation. In addition, the modules are built to withstand all weather conditions including 3.800 N/m² (~270 km/h) wind load and 5.400 N/m² (~55 kg/m²) snow loads, well above IEC standard requirements. The product is ideally suited to rooftop installations where weight, power, and aesthetics are key customer considerations.

"The new BlackPearl™ module delivers 10% more power than conventional polycrystalline products leading to lower balance-of-system and installation costs per watt," said Dr. Zhengrong Shi, Suntech's Chairman and CEO.

Utilizing different technology than Pluto products, the BlackPearl™ module is comprised of 6-inch square cells that contain minimal oxygen content and achieve 18% conversion efficiency at cell level. Suntech's in-house R&D and wafer production team developed the technology based on a wafer manufacturing process that combines the high efficiency of monocrystalline wafers with the reliability of polycrystalline wafers. All Suntech BlackPearl™ modules also feature an anti-reflective surface trapping the sunlight into the cells combined with a hydrophobic self-cleaning surface structure.

Suntech will start shipping the new products to Europe starting in June 2011. Suntech will display the STP250S-20/Wd+ BlackPearl™ modules and other latest products at booth A2 #380, at the Intersolar Exhibition, New Munich Trade Fair Centre, Germany from 8-11 June, 2011.
