On both sides of a roof of a semi-detached house in Ennepetal, North Rhine-Westphalia, three Solar Frontier PowerSets in total were installed. The east-facing roof provides space for two 6.9 kWp PowerSet of 42 modules each and on the small west-facing roofside a 3 kWp PowerSet of 18 modules. The plant of 16.8 kWp total capacity is expected to produce 14,600 kWh of electricity annually and thus offset about 12,000 kg of CO2 emissions per year.

Thanks to the precisely matched components of the PowerSets, consisting of inverters, modules, connecting cables, DC-Cables, plugs and sockets – the installation of PowerSets was very easy. Each PowerSet can be installed in many different ways including in places where nearby objects partially shadow the panels. The challenge of this roof was in the east-west orientation. Thanks to good low-light behavior, the CIS thin-film modules also work in the early morning and the late evening hours, leading to a higher output generation compared to other modules.
