Suntech Power Holdings today announced a new generation of its 72-cell module for commercial and utility-scale electricity generation in Europe.
The SuperPoly STP305-24/Ve, with 15.7% efficiency, is suited for large-scale commercial projects seeking a low levelized cost of energy (LCOE). In addition, the new Ve-Series modules feature a slim frame design lowering storage and shipment costs by up to 16%, according to Suntech.
The SuperPoly STP305-24/Ve solar module will be on display during PVSEC 2012 (hall 3.1, booth H13) in Frankfurt 24-28 September.
The new modules will be available throughout Europe starting in November 2012.
Suntech's SuperPoly technology achieves high efficiency by utilizing an advanced ingot casting process, which combines the benefits of mono-crystalline silicon wafers (high efficiency) and poly-crystalline silicon wafers (square wafers and better temperature performance) into one product. With 72, 6-inch cells, the new 1956x992x40mm module has a high fill factor and low project installation costs.
An improved design reduces frame thickness from 50mm to 40mm, providing a 1.2kg reduction in total module weight, without compromising module stability or durability. The module is certified to withstand extreme wind (3,800 Pascal) and snow (5,400 Pascal) loads.
This frame design also allows for more modules to be installed on rooftops with tight weight constraint, highly relevant for many industrial projects.
In addition, a new texturing process has changed the cell appearance of the SuperPoly Ve-Series. Whereas former SuperPoly cells showed both mono- and poly-silicon parts, the new cell’s appearance is similar to standard polycrystalline cells while maintaining the SuperPoly advantages such as higher efficiency.
The new product line also features Suntech’s 25-year power output warranty, with positive power tolerance, and a workmanship warranty of 10 years.
