The nursery extension surrounds the older building, which houses the kindergarten, on three sides (south, south-east, east). This means that the system, which consists of three parts distributed parallel to the roof, has an ideal orientation for self-consumption: the eastern part already supplies solar energy in the early morning. Then the south-east part takes over and finally the south side, which supplies power until late afternoon when the facility closes. "However, self-consumption is not an issue until the subsidies expire," says Dipl.-Ing. Beatrice Küttner.
The civil engineer is the property manager in charge in Steinberg and responsible for looking after the photovoltaic system. "The former mayor who initiated the plant in 2010 was a master electrician and chairman of the electrical guild. He already had a lot of experience with photovoltaic systems back then and has really done the community good with the system," says Küttner. The technically trained eye can see at first glance that not only the available space has been optimally used, but also that all distances to the roof edge are correct.
