JA Solar 550W Solar Panel JAM72S30-550/GR

The JA Solar 550W Solar Panel JAM72S30-550/GR is a high-efficiency monocrystalline half-cell module engineered for strong, reliable performance in commercial and utility installations. Built with 11BB PERC cell and gapless ribbon technology, it offers higher output, reduced shading losses, and better temperature-dependent behavior. At STC, it delivers Voc 49.90V, Vmp 41.96V, Isc 14.00A, and Imp 13.11A, achieving a solid 21.3% efficiency. Enhanced weak-light response and lower resistive loss ensure stable energy yield throughout the day, while the module’s robust mechanical load tolerance and 25-year linear power warranty with 0.55% annual degradation guarantee long-term durability and consistent performance.
