Astronergy ASTRO N7 625W n-type TOPCon Bifacial Dual Glass Module - CHSM66RN(DG)/F-BH

The Astronergy ASTRO N7 CHSM66RN(DG)/F-BH is a 625W n-type TOPCon bifacial dual glass module delivering 23.1% efficiency across 132 half-cells, built for utility-scale plants and large commercial rooftops. TOPCon 4.0/5.0 cell technology with SMBB design improves current collection and cuts resistive loss, while a low Voc design allows more modules per string — directly reducing the number of strings, combiner inputs and cable runs needed per megawatt. Bifaciality of 80±5% is among the highest available. Under bifacial nameplate conditions with 135W/m² rear irradiance the module produces 689.1W, a 10% gain over the front-side rating. A -0.29%/°C Pmax temperature coefficient holds output through hot afternoons. Dual 2.0+2.0mm glass in a silver anodized aluminium frame withstands 5400Pa front and 2400Pa rear loading. The IP68 junction box carries HCB40 connectors as standard with MC4-EVO2A optional, and 4mm² cable. Rated for 1500V DC systems (IEC and UL) across -40°C to +85°C with a 35A maximum series fuse. Degradation is under 1% in year one and 0.4% annually thereafter, retaining 87.40% at year 30. Backed by a 15-year product warranty and 30-year linear power warranty, and listed Tier 1 in the 2026 PV Module Reliability Scorecard with performance underwritten by an international insurer.
