For many private homeowners, having their own solar system on the roof is an attractive prospect. Be it due to the rise in electricity prices or a growing environmental awareness. With various measures such as the increase in the tax exemption limit from 10 kWp to 30 kWp (as of June 2023) in Germany, politicians are promoting the construction of new solar systems on private homes. In Austria, 100,000 applications for subsidies were approved in a first round (PV magazine Germany) and Switzerland plans to abolish the basic contribution for small PV systems in 2024 (PV magazine Germany).
