HIGH MODULE conversion efficiency. Ideal output for single panel: 200W per day (depending on the availability of sunlight). Bypass diode minimizes power drop caused by shade and ensures excellent performance in low-light environments work with all weather even when there is mist and rain EL tested solar modules; no hot-spot heating guaranteed. Advanced encapsulation material with multilayered sheet laminations to enhance cell performance and provide a long service life. Corrosion-resistant aluminum frame for extended outdoor use, allowing the panels to last for decades as well as withstand high winds (2400Pa. Anti-reflective, high transparency, TPT back sheet ensures smooth performance over a long period of time SOLAR POWER has long time lasting than any other source of power
