Co2Pro is a Danish wholesaler for photovoltaic systems, located in the town of Ikast. The company supplies high quality photovoltaic systems to a nationwide network of installers. Co2Pro offers their customers all photovoltaic components including modules, inverters and mounting systems, which are selected only from well-known manufacturers.

This 6.96 kWp installation in the Danish town of Silkeborg was installed by the Co2Pro partner Free Energy Limited, which is one of the most experienced installers in Denmark. The installation on the residential rooftop, consisting of 48 CIS thin-film modules, was connected to the grid in December 2011. All modules were mounted on the flat roof of the house with north-east orientation and a very low tilt angle of zero degrees. Despite these challenging conditions, the system is expected to produce 5,500 kWh of energy per year and can thus satisfy the energy needs of the homeowner. The installation will additionally offset three tons of CO2 emissions per year.

The Solar Frontier modules are well suited for flat rooftop installations because of their good low light behavior, which is typical of non-optimal low tilt angles. An additional factor for the homeowner was the discreet integration of the solar installation into the overall appearance of the roof. The black appearance of the modules works appealingly with the overall look of the house.
