ASTRO N7 CHSM66RN(DG)/F-BH Bifacial Series 615W

The ASTRO N7 CHSM66RN(DG)/F-BH Bifacial Series 615W is engineered for higher bifacial gain, stable outdoor performance, and long-term energy production using n-type TOPCon 4.0 technology. At STC, it delivers Voc 48.89V, Vmp 41.43V, Isc 16.02A, and Imp 14.84A, achieving 22.8% efficiency with improved behavior under weak-light and high-temperature conditions. Its SMBB design minimizes resistive losses, while the 2.0+2.0 mm dual-glass structure ensures durability with 5400Pa front and 2400Pa rear load capability. With industry-leading degradation—1% first year, 0.4% annually—and strong warranty coverage (15-year product, 30-year power), the 615W model is ideal for C&I and utility-scale systems needing consistent high yield.
