High-quality A-grade solar cells from SunPower. Very high module efficiency of up to nearly 24%. The surface is made of tempered ESG solar glass with a weather-resistant coating. It features a corrosion-resistant black aluminum frame for extended outdoor use, complete with pre-drilled mounting screws. The IP68 junction box contains a 90 cm long 4 mm² double-insulated solar cable and a solar connector. Two integrated bypass diodes minimize power loss in shaded conditions. A special anti-reflective coating allows for higher light absorption. The white back minimizes heat effects and energy losses. This product is lighter and smaller than conventional solar modules.
