Perc cell technology: By passivating the rear side, a PERC module can utilise more red sunlight and the module efficiency increases by up to 1 %. Perc modules achieve better performance, particularly in weak or diffuse light conditions in the morning and evening hours. Elegant design with silver frame, but without heat generation or loss of performance due to white backsheets. High-quality class A solar cells, higher efficiency thanks to 210 mm cells even in poor light conditions. Surface made of tempered ESG solar glass with weatherproof coating. Corrosion-resistant aluminium frame for prolonged outdoor use with pre-drilled mounting holes. IP68 junction box with 90cm long 4mm² double insulated solar cable and MC4 plug. Integrated bypass diode - minimised power drop when shaded. SGS-TÜV Saar tested in accordance with applicable standards. Guaranteed plus tolerance (0~ + 3%).
