PRODUCT HIGHLIGHTS
N-Type TOPCon Monofacial Solar Module. 625–645 W of front-side rated power, with the construction and operating characteristics detailed below.
The 625-645 W range uses N-type TOPCon cells, with five STC power classes and maximum module efficiency of 23.07%.
The monofacial module uses 156 half-cells arranged 6 × 26. STC and NMOT electrical tables describe its front-side output.
3.2 mm coated tempered front glass is supported by an anodized aluminum frame. The 30.0 kg module lists 2400 Pa wind and 5400 Pa snow loads.
The IP68 junction box includes three bypass diodes. Module operation spans -40°C to +85°C, with a -0.30%/°C Pmax temperature coefficient.
