Greece approves balcony solar panels and revises net‑billing rules

Greece has adopted a new regulatory framework that permits households to install small‑scale photovoltaic systems on balconies, limited to 800 W and operating on a zero‑export basis. The measures also simplify collective self‑consumption arrangements in apartment buildings and introduce a Digital Self‑Consumption Registry to streamline procedures.

In parallel, the Ministry of Environment and Energy is revising its net‑billing and virtual net‑billing scheme. Under the draft rules, batteries paired with self‑consumption installations may export stored electricity but are prohibited from charging directly from the grid, creating a clear separation from merchant storage. Stand‑alone batteries are allowed provided they do not feed electricity into the grid and their capacity does not exceed the consumer’s contracted connection capacity. The reforms aim to address the limited growth of Greece’s distributed solar market by reducing complexity and improving the financing outlook for rooftop solar and storage projects.

The consultation on both the balcony‑panel rules and the net‑billing amendments will close on 20 July 2026.
