Solaxis, located in the Nordrhine-Westphalian town of Kamp-Lintfort (Western Germany), is an experienced partner in the distribution, planning and installation of photovoltaic and solar thermal systems. Founded in 2007, the firm’s goal is to accompany its customers on the way to using renewable energy solutions. Solaxis, a company of seven employees, has installed about 4.2 MW as of 2012.

The installation, consisting of 198 Solar Frontier CIS modules, has a total capacity of 29.7 kWp and has been installed on the east-facing roof of a wastewater treatment plant. Connected to the grid in December 2011, the installation is expected to produce 24,660 kWh of energy and save about 22 tons of CO2 emissions. The customer and operator is the local utility company of Kamp-Lintfort. The utility services 21,000 households and owns 400 kWp of photovoltaic capacity.

The Solar Frontier CIS modules were compelling because of their higher output compared to conventional crystalline silicon modules, especially in non-optimal conditions. This is the result of the modules’ higher shadow tolerance and low light behavior, which ensures higher output even under non-optimal, but sometimes unavoidable, conditions, such as eastern orientation and the installation´s low tilt angle of only 10°. Additional compelling factors for the Solar Frontier modules included its ease of mounting and high tolerance against dust.
