Maximum efficiency and durability are key to every solar system, because only the combination of both elements guarantees a return-on-invest. LG has managed to take out the maximum of the available area with its new modules. In addition, the elegant modules are extremely resistant against any harm, e.g. can take pressure up to 5,400 pa. With less than 17 kilos, they are easy and thus cheap in installation, another positive aspect for the overall economic calculation.
