KfW 270 is a loan (not a grant) for private individuals, companies and municipalities for renewable systems, including PV with storage. The rate depends on risk class and collateral (sources quote 3.3–11.6%). Apply through your bank before buying or extending the system.
State programmes: only a few remain active in 2026 (Bavaria, Lower Saxony, Thuringia and Saxony-Anhalt ended theirs); check the local programme before quoting.
