JA Solar N-type 590W Bifacial Solar Panel JAM72D40-590/LB

The JA Solar 590W JAM72D40-590/LB is a high-efficiency N-type bifacial double-glass module designed for superior long-term performance and lower LCOE. Featuring SMBB N-type cells, it offers ultra-low LID, a stronger low-irradiance response, and improved temperature behavior for consistent generation across all conditions. At STC, it delivers Voc 52.00V, Vmp 43.41V, Isc 14.35A, and Imp 13.59A, reaching an impressive 22.3% module efficiency. The bifacial design provides up to 80% ±10% rear-side gain, boosting overall energy yield for utility-scale and commercial projects. Backed by a 30-year linear power warranty, with only 1% first-year degradation and 0.4% annual degradation, this module ensures durable, high-output solar performance.
