Prima Solar, located in Neuruppin, Brandenburg, offers its customers full package photovoltaic solutions for small residential rooftops up to bigger commercial installations. They cover all related areas starting from planning to finance and installation. So far the company has completed more than 800 solar installations for residential and commercial customers as well as for investors.

Within only three weeks, 11,496 Solar Frontier CIS thin-film modules of the type SF 150-L were installed on several rooftops of agricultural buildings in Sonneberg. The installation mounted on several cowsheds has a total capacity of 1,724.4 kWp and is expected to generate 1,538,165 kWh of electricity per year. Thus about 340 four-person households can be supplied with solar energy and consequently 824 tons of CO2 are avoided yearly.

Thanks to its unique CIS technology, Solar Frontier modules show good performance even under circumstances considered to be less than optimal, such as low tilt angle of only 14 degrees or an east-west orientation. Due to their good low light behavior and high shadow tolerance, Solar Frontier’s CIS thin-film modules generate higher output levels than crystalline modules. In addition, Solar Frontier’s modules have passed all ammonia resistance tests, certifying their suitability for installation in corrosive environments, typically found in agricultural plants hosting cow and hen farming. The CIS modules are free of cadmium and lead and due to their black appearance integrate well in the surrounding environment.
