Medium-sized systems provider green solar AG is headquartered in Winhöring (Altötting), Germany. The company offers its customers turnkey photovoltaic systems for rooftop and free-field plants, taking over the complete support for projects from planning and installation to associated services. As a service provider for renewable energy, the company has experience of more than 1,500 completed projects.

The installation of this private rooftop in the Bavarian town of Erlbach with 125 Solar Frontier CIS thin-film modules took place in January, 2012. Due to the excellent low-light behavior of the CIS technology, which plays an important role especially on roofs with an east-west orientation, the customer chose the CIS thin-film modules from Solar Frontier. CIS Solar Frontier modules begin working earlier and continue working longer before the sun sets and thus achieve a higher output compared to crystalline silicon modules.

Despite non-optimal conditions for PV as an East/West oriented rooftop, the plant has achieved a yield of 17,179 kWh according to green solar AG, exceeding the output forecast of 16,022 kWh by about 7 %. The annual CO2 savings of just over 14 tons are a welcome contribution to climate protection. Another reason to choose the lead- and cadmium-free Solar Frontier CIS modules was their aesthetics. The black design of the modules fits very well with the modern architecture of the private house.
