Intelligent module design 36 PowerMax� solar cells form the heart of the module. These cells make optimum use of the module surface area. Thanks to their square shape, they are highly efficient and still provide the maximum power possible even under low light level conditions. The specially hardened front glass has excellent light transmitting properties and protects the module against most adverse environmental conditions such as hail or ice. The solar cells are laminated in EVA (ethylene-vinyl acetate) between a multilayer rear film and the front glass. This permanently laminated assembly protects the cells against moisture and ensures electrical insulation. A torsion-resistant module frame made of anodized aluminum guarantees particularly high mechanical strength. |
