It’s comforting to know that MAGE POWERTEC Plus modules can handle the toughest demands
with regard to stability and corrision resistance. This is due to their engineered hollow-section frame and 3,2 mm (0,13 in) special solar glass. We also use high-quality EVA foil, which is ideal for embedding solar cells, while the weatherproof foil on the back of the modules protects against humidity. As a final security measure, we place a junction box with bypass diodes on the back of the module to avoid overheating of the individual solar cells (hot-spot effect). Our extremely robust modules resist a maximum pressure of 5,400 Pa (= 113 psf).
