The new self-consumption framework in force since 14 September 2026 (Government Gazette B' 5573/14.09.2026) regulates so-called balcony solar for the first time: small systems mounted on a balcony or another surface of the building and plugged into a socket.
The basics
They may feed at most 800 W into the home installation and the energy is for your own use only, with no export to the grid. They can be combined with a battery. Limits apply per supply point, so you cannot add several systems to exceed them. Registration is online, on a HEDNO (ΔΕΔΔΗΕ) portal expected by the end of 2026.
When they can be installed
Installation is allowed once HEDNO publishes its safety specifications, due by 31 October 2026. Before buying a system, ask us whether all steps are in place.
Who it suits
People in apartment blocks without roof access, tenants who cannot make permanent changes, and anyone with steady daytime consumption. We check the circuit and socket, recommend proper equipment and help with the registration.
