Sonnenkraft, an Austrian solar module manufacturer, has introduced a new back-contact TOPCon panel for rooftop applications, according to a report from pv magazine Germany.
The product, designated 480GG2RNE, is a glass-glass module built with 108 TOPCon half-cells. It delivers a power output of 480 watts and achieves a conversion efficiency of 23.52 percent.
The module measures 1,800 millimeters by 1,134 millimeters by 35 millimeters and weighs 24.5 kilograms. It is designed to handle a maximum system voltage of 1,500 volts and can operate in temperatures ranging from minus 40 degrees Celsius to 85 degrees Celsius. The temperature coefficient for the module is minus 0.26 percent per degree Celsius.
Sonnenkraft includes a 15-year product warranty for the module. The company guarantees that the module will retain 99 percent of its original power output in the first year, with an annual linear degradation rate of 0.4 percent over 30 years.
The back-contact design relocates all electrical contacts to the rear side of the cells, a configuration the company says improves efficiency, shade tolerance, and aesthetics. This creates a busbar-free front surface that increases the active cell area exposed to sunlight and gives the module a uniform black appearance.
According to the company, the module is suited for residential rooftop installations, building-integrated photovoltaics, and other design-oriented applications. It is certified under several IEC standards, has passed the HW3 extended hail test, and is resistant to salt mist and ammonia exposure. The module also includes an integrated shading management system intended to reduce power losses under partial shading conditions.
