The BE Netz AG, headquartered in Lucerne, Switzerland, is a competent partner in building service technologies. The company is specialized in generating energy and heat from solar energy. The services of BE Netz AG include engineering services, planning and realization of photovoltaic and solar thermal systems and replacement of heating systems with renewable energies. With their experience from numerous solar systems, BE Netz AG provides its customers with individual and customized solutions in renewable energies.

The 22 kWp system with CIS thin-film modules was installed at the end of 2011 on the roof of an art gallery, which is on the grounds of the state broadcaster Beromünster. The area, containing a broadcasting building and the 215 m high transmission mast de-commissioned in 2008 was acquired by the Swiss artist Wetz for a symbolic 5 Swiss francs, and has now been converted into an arts center. In collaboration with BE Netz AG, the Energy Academy was established, which advocates for the promotion of renewable energies.

The 171 thin-film modules on the roof of the Art Gallery 4 supply the area with electricity and heat from renewable energy sources, along with a solar thermal plant and a wood chip heating plant, the area with electricity and heat from renewable energy sources. Installed on the southeast side of the building, the PV system will generate over 20,000 kWh of energy annually and will avoid almost 12 tons of CO2 emissions. The Solar Frontier modules convinced the customer, in addition to their high performance even under non-optimal irradiation angles, especially by their black appearance, which additionally upgrades the overall look of the building.
