Astronergy 620W N-Type Bifacial Solar Panel

The Astronergy 620W N-Type Bifacial Solar Panel is a high-performance solar module engineered to provide excellent energy generation, high module efficiency, and reliable long-term operation. It belongs to Astronergy’s ASTRO N7 CHSM66RN(DG)/F-BH Bifacial Series and uses advanced N-Type monocrystalline TOPCon 4.0/5.0 cell technology.

Its bifacial double-glass construction allows the panel to produce electricity from both the front and rear surfaces. Under standard test conditions, the module delivers a rated output of 620W with an efficiency of 23.0%. Under Astronergy’s bifacial test conditions, using 1000W/m² front irradiance and 135W/m² rear irradiance, its rated bifacial output reaches 683.6W.

The module features 132 half-cut cells, SMBB technology, low open-circuit voltage design, and an IP68-rated junction box. Its low-voltage design allows more modules to be connected in each string, helping reduce balance-of-system costs in commercial, industrial, and utility-scale solar projects.

With a temperature coefficient of only -0.29%/°C, the Astronergy 620W panel maintains dependable performance during high-temperature conditions. Its double-glass structure, anodized aluminium frame, and mechanical load resistance provide additional durability for demanding outdoor solar installations.
