Self-consumption vs selling back: what to choose in 2026?
By KlimaGrid Energy Desk · January 2, 2026 · 7 min read
Should you consume your solar electricity or sell it back to the grid? In 2026, the answer leans clearly towards self-consumption, but context matters.
Self-consumption, the most profitable
Every kilowatt-hour consumed directly saves you from buying electricity at the retail rate, often around €0.20/kWh. That is far more than the feed-in tariff.
Selling back the surplus
Unconsumed surplus can be fed into the grid at the feed-in tariff (about €0.1374/kWh). Worthwhile, but less advantageous than avoiding a purchase.
The role of the battery
A battery raises your self-consumption rate to 70-80% by storing daytime production for the evening. With the €2,250 premium, it becomes a sensible choice for many households.
