New self-consumption rules: what changes for rooftop solar in Greece

On 14 September 2026 (Government Gazette B' 5573/14.09.2026) a new ministerial decision on self-consumption came into force in Greece. It replaces the previous framework and aims to make it easier for households and businesses to produce and use their own electricity.

What changes

For home solar systems up to 10.8 kW, the value of surplus energy is credited to your electricity bill. Contracts with the supplier are signed through a faster, less bureaucratic process, so systems can start operating sooner.

Batteries and apartment buildings

Standalone batteries, without solar panels, are now allowed to store grid energy for your own use, with simpler licensing. Shared self-consumption, for example in apartment buildings, becomes easier. Projects that already had a grid connection offer but could not start get a new deadline.

What it means for you

Under net billing you gain most from the power you use while it is being produced. Correct sizing matters, and for many homes and holiday rentals so does a battery. We can study your consumption and tell you what pays off.
