Solar panels in Belgium: what do I get for the power I feed in?

The short answer

If you produce more than you use, the surplus goes into the grid. How you are paid for it depends on the national scheme.

📜 The rules in Belgium

Solar panels

There is no national feed-in tariff. Solar owners sell surplus power through an injection contract with a supplier; in Flanders the reverse-running meter has been replaced by the digital meter. Wallonia and Brussels have their own prosumer and green-certificate rules.
