German module manufacturer Bauer Solar has introduced a new back-contact solar panel to its product lineup, according to a report from pv magazine Germany. The initial offering is a full-black glass-glass version with a power output of 480 watts.
The panel is constructed using 108 bifacial half-cells and has dimensions of 1,800 by 1,134 by 30 millimeters, with a weight of 24.8 kilograms. The company states the module achieves a power conversion efficiency of 23.52 percent.
Specifications include front and rear glass panes that are each 2 millimeters thick and feature anti-reflective coatings. The module frame is constructed from anodized black aluminum alloy. The product is rated for operation in temperatures ranging from -40 to 85 degrees Celsius and can handle a maximum system voltage of 1,500 volts. It is designed to withstand static loads up to 5,400 pascals and carries an HW3 hail resistance rating, alongside fire protection class A certification.
Bauer Solar is providing a 30-year product and performance warranty for the new module. The linear performance guarantee ensures a minimum of 88.85 percent of the original output after three decades. The manufacturer indicated plans to increase the output of its back-contact modules to 500 watts later this year with additional variants.
Alongside the new back-contact technology, the company will continue its focus on TOPCon products, with an expansion of that portfolio planned for the coming summer. The new TOPCon variants are expected to reach an output of 465 watts. Bauer Solar targets the residential rooftop market with these modules, positioning them as an economical solution, though specific pricing was not disclosed.
