China’s DAS Photo voltaic presents an all-black n-type bifacial photo voltaic panel with 54 M10 PV cells and a double-glass design for residential rooftop functions. It’s licensed in accordance with IEC61215 and IEC61730 requirements.
The sequence labeled Black-Through contains 5 completely different panels with energy scores of 410 W to 430 W, and efficiencies from 21.0% to 22.0%. The open-circuit voltage ranges from 37.73 V to 38.49 V and the short-circuit present is between 13.91 A and 14.23 A. Every module measures 1,722 mm x 1,134 mm x 30 mm and weighs ours is 24.7 kg.
The panels have a junction field with an IP 68 ranking and a body made from anodized aluminum alloy. Each side of the modules are coated with 2 mm glass. They’ve an working temperature between -40 C and 85 C, and the temperature coefficient is -0.3% per diploma Celsius.
“The Black-Through module is extra superior in weight load / m2 as a result of mild dual-glass construction, which is 3 kg lighter than the identical model of the traditional dual-glass module and 0.7 kg lighter than monofacial module,” the producer. stated in an announcement.
The panels can be utilized in PV programs with a most voltage of 1,500 V. DAS Photo voltaic provides a 30-year assured energy output for 87.4% of the preliminary yield and a 15-year product guarantee.
The producer claims a bifaciality issue of as much as 80%. The ability positive aspects vary from 10% to 30% for the 410 MW and 430 MW modules, respectively.
