Each solar panel is subjected to two times of EL (Electroluminescent) tests for semi-finished and finished products before shipment, in order to prevent the crack and black core defects on the solar panel from affecting its output power and lifespan, to ensure its perfectionism. MTTP technology (MPPT- Maximum Power Point Tracking) help the system capture the power
generated by the solar panel more efficiently and dynamically, which make the conversion efficiency 15%-20% higher than the PWM controller. The surface of the solar panel use etch-treated and anti-reflective coating process to enhance the absorption of light and increase the output power of the cell. The conversion efficiency is ≥20%. The solar panel uses high-quality EVA adhesive to be not aged and turning yellow in long-term outdoor working, to ensure high light transmittance and long lifespan. The solar panel uses 3.2mm ultra-white cloth tempered glass, which perfectly protects the solar panel from wind and snow and hail impact. The light transmittance is >91%, achieving perfect balance in preventing dust adsorption and light transmittance.
