The federal government may also provide additional funding for the expansion of solar systems and other renewable energies.
The European Commission, which is responsible for ensuring compliance with competition rules in the EU, approved corresponding measures on Tuesday.
According to the Brussels authority, these are necessary to expand renewable energy sources and reduce emissions of climate-damaging greenhouse gases.
Specifically, subsidies for solar systems on private roofs are to be expanded in order to feed additional electricity into the general grid.
The EU Commission also approved additional state tenders for photovoltaic systems on open and roof areas and an adjustment of a market premium for electricity producers in the area of innovation.
The federal government recently launched numerous measures to promote the expansion of renewable energies.
For example, expansion volumes for wind power and solar systems have increased significantly.
By 2030, at least 80 percent of gross German electricity consumption should come from renewable sources.
It's currently just under 50 percent.
