During the cloudy winter months, you rarely see the sun, but the sun offers enormous potential for energy generation over the entire year. In the municipality of Kirchseeon, they no longer want to let this go unused in the future, but instead want to upgrade as many municipal properties as possible with photovoltaic systems (PV). However, a feasibility study has now shown that this is not easily possible everywhere. Some roofs are even completely unsuitable for solar systems.
This applies to the new ATSV home, for example. Although this is a very pretty building, as electrical engineer Konrad Bräu said at the most recent meeting of the municipal council, considerable structural work would be necessary to install a PV system there. This is primarily due to the fact that the solar modules cannot be properly attached to the round seam roof – and a conversion would simply be too expensive. “The costs incurred here are only in small proportion to the benefit,” said Bräu, who had inspected the roofs of various properties on behalf of the municipality.

The electrical engineer also encountered obstacles in the building next door to the clubhouse. Although the ATSV hall has a very large roof, which would actually be well suited for PV, it would have to be extensively renovated beforehand for structural reasons. In this case, too, the use of solar energy would not pay off, according to Bräu. The same applies to the fire station in Kirchseeon-Dorf. Here, however, the cabling is more of a problem. In order to be able to draw electricity from the roof, the old school building next door, from where the power supply is controlled, would have to be converted. “Here, too, very high costs would arise,” said Bräu.

On the other hand, things are looking a little better at the town hall, according to the expert, a smaller PV system would be theoretically possible here – albeit with one restriction. “The installation is not very easy, just like the cable route,” explained Bräu. The building is quite high due to its tower shape, which does not exactly make the work easier. Upgrading with solar modules would therefore be significantly more expensive here than elsewhere.
For example at the house for children on Spannleitenberg or the building yard, where smaller systems are already installed. The Spatzennest kindergarten or the primary and secondary school in Kirchseeon would also be suitable for the use of solar energy. According to Bräu, the latter building could even have “a giant system” that could generate more than 130 kilowatts peak.
It remains to be seen on which of the roofs solar energy will actually be tapped later. According to Konrad Bräu, the municipality must now seek dialogue with the energy supplier and have a grid compatibility check carried out. “After that you can start planning the individual projects.”
