The solar modules are of the type CIGS, produced using thin-film technology. The electricity-generating layer is enclosed between two sheets of glass with a total thickness of 7,3mm which makes them long-term protected against all weather, wear and tear influences. Thanks to the low temperature coefficient (-0.32% / K), these modules have an efficiency advantage even up to 12.5% compared to standard solar modules. The modules are less sensitive to shade and produce even in diffuse light electricity so they can even be applied on two roof sides, ideal for a more even power output throughout the day. The system has been tested for a long time on physical properties. Because of the sophisticated air gap behind the solar modules, the cooling and vapor diffusion, are arranged in a proper manner.
The water tightness from ridge to rain gutter is achieved by the patented fastening system in such a way that the modules lay over each other. Between the modules-columns are vertical gutters which discharge the excess water into the rain gutter. Sound tests according EN ISO 717-1 show that the Lociⓟ solar roof has excellent acoustic properties. Example: RC9 insulation, with roof tiles = 38 dB, RC9, with Loci = 40 dB
