KfW's flagship renewable energy loan (programme 270) has been updated for 2026 with an individual, credit-dependent rate (market-tracking) for 10-year terms. The loan now explicitly covers home battery storage paired with solar, up to €150 million per project. Applications are made through the homeowner's bank, not directly through KfW.
