Schirra Solar Consulting GmbH, located in Wasserburg on Lake Constance, is a professional solar energy partner particularly for small and mediumsized crafts enterprises. Founded in 2009, Schirra Solar plans and installs turnkey solar systems.

Schirra Consulting GmbH has several sales offices and collaborates with a number of other solar energy specialist firms.

In July 2011, a roof-mounted solar installation with Solar Frontier CIS thin-film modules was installed by Buch Solar GmbH and was connected to the grid on a private rooftop in Trier, in Rhineland-Palatinate. The 65 installed CIS modules have a total installed capacity of 8.45 kWp. The residential rooftop installation is expected to produce 5,113 kWh annually and reduce polluting CO2 emission by 4,510 kg per year.

The challenge of this installation was to use a north-east oriented rooftop with a tilt angle of 35°. Under these suboptimal conditions, Solar Frontier CIS thin-film modules showed especially better performance characteristics than conventionally used crystalline modules. In addition to the high efficiency of the modules even under partial shadowing and low-light conditions, the lead and cadmium free content of Solar Frontier CIS modules were also compelling factors.
