The BALTICSOLAR solar installation in Wankendorf was a real challenge due to the east/west orientation of its rooftop and a low tilt of only 10°. Solar Frontier CIS thin-film modules were the perfect solution as they offer the owner optimal energy output even under these non-ideal conditions.

BALTICSOLAR Scaffolding Company

This commercial rooftop installation by BALTICSOLAR is evidence of efficient power generation with optimal output, even on east or west oriented roofs.

Based in Northern Germany, BALTICSOLAR is an innovative and leading company, founded in 2004 by solar energy specialists with deep experience in developing and marketing photovoltaic facilities. From consulting to purchasing and planning by its engineers, right up to installation by the experienced BALTICSOLAR construction team – all theses services are delivered by the same company.


In November 2010, BALTICSOLAR planned and installed a rooftop mounted solar power plant for a small business scaffolding company in Wankendorf (Schleswig-Holstein). The system consists of 1,197 CIS thin-film modules with a total capacity of 98.75 kWp.


The challenge of this installation was to compensate for the low tilt angle of the modules on an east-west oriented rooftop. The installed Solar Frontier CIS thin-film modules, generate a higher overall output compared to crystalline solar modules, especially under low light conditions common to east- and west-aligned roofs. An additional decisive purchase factor was the aesthetic uniform black appearance of the modules, which integrates well with the surrounding environment.


The output data from January to the end of June outperformed expectations with an output of 48,000 kWh. This increases the expected system output from 784 kWh/kWp to 967 kWh/kWp annually.
