N-type Solar Panel, 25% High Efficiency The Callsun 100 watt solar panel is built with advanced N-type solar cells, delivering an impressive conversion efficiency of 25%. N-type solar cells provide higher power output compared to conventional solar panels (which typically achieve a maximum of 23.5%) of the same design. 16BB Solar Cell Design Compared with traditional 9BB/10BB solar cells, the Callsun 100W 16BB solar panel utilizes advanced 16BB technology to enhance photoelectric conversion efficiency, while reducing hot spot risks and mitigating the impact of micro-cracks. This ensures a longer service life and superior module performance. Compact Size & Easy Installation Each 100W solar panel measures 31.1 x 22.7 x 1.1 inches and weighs 11.4 lbs, 15% smaller than traditional panels. With pre-drilled holes for quick, easy mounting, this 12V monocrystalline solar panel is ideal for easy installation in applications like RVs, boats, cabins, off-grid systems, and backup power setups, offering versatility and convenience for all your solar power needs.
