What changed
The Bundesnetzagentur published the EEG remuneration values that apply to solar installations commissioned from 1 August 2026 through 31 January 2027. The published values differ by installation size and whether the system uses partial feed-in (surplus export) or full feed-in.
One headline tariff is not enough
For building-mounted systems up to 10kW, the regulator lists 8.10 ct/kWh for partial feed-in and 12.62 ct/kWh for full feed-in for this commissioning window. Larger power bands use different values. A payback model therefore needs the system size and operating mode, not simply “the German feed-in tariff.”
Self-consumption can still dominate household economics
Electricity used directly in the home can have a different value from exported electricity. Battery storage can shift solar generation into later consumption, but its economics depend on battery cost, usable capacity, losses and the household’s actual load shape.
Registration and grid steps remain separate
Germany’s Marktstammdatenregister and grid-connection requirements should be checked independently of the remuneration table. A system does not become compliant merely because the tariff assumption is correct.
How to use the update
When comparing quotes, write down commissioning date, array size, expected annual generation, self-consumption assumption, export mode and the exact remuneration band. Continue with the Berlin guide or the Melnti payback guide.
