Solarever 410W 72-Cell MONO Perc Framed Solar Panels. Multi Busbar Solar Cells adopts new technology to improve modules’ efficiency and offer a better aesthetic appearance. Higher module conversion efficiency (up to 20.38%) benefits from half cell structure (low resistance characteristic), advanced glass and cell surface textured design to ensure excellent performance in low-light environments, and excellent Anti-PID performance guarantee limited power degradation for mass production all make these panels ideal for installations in regions of high temperature and high humidity.
