Greece has proposed allowing 800-watt solar systems on apartment balconies as part of a wider overhaul of self-consumption rules. The plan would limit balcony PV to on-site use only, allow home batteries solely for self-consumption, and simplify collective schemes in apartment blocks. The package also proposes a faster smart-meter rollout and an electronic registry to streamline administration.
Greece Proposes Legalising 800W Balcony Solar in Major Self-Consumption Reform

Greece’s Ministry of Environment and Energy has proposed reforms that would allow small photovoltaic (PV) systems to be mounted on apartment balconies for the first time, part of a broader overhaul of the country’s self-consumption rules.
What the Proposal Would Do
Under the draft rules reported by PV Magazine, residents could install compact, 800-watt solar-panel systems on balcony areas. Power produced by those systems would be restricted to on-site use only — no electricity could be exported back to the public grid — and the units would need to meet defined safety standards to protect local electrical installations.
Battery Storage, Collective Schemes and Administration
The proposal also permits home battery storage, but only when the battery is used exclusively for self-consumption. The reform package aims to simplify rules for collective self-consumption in apartment buildings and residential complexes, making it easier for neighbors to share generation within a building or community.
Officials say the package is intended to clear up administrative and regulatory gaps that have hindered uptake under the current framework. Measures include a faster rollout of smart meters for owners of self-consumption systems and the creation of an electronic self-consumption registry to move procedures online, improve data sharing and reduce paperwork.
“Strengthening energy democracy through self-consumption remains a key priority for the Greek government,” the ministry told PV Magazine.
Why It Matters
Rooftop PV has often been inaccessible to apartment dwellers who do not control their building’s roof. Allowing balcony-mounted systems could open the door to lower electricity costs for renters and others without roof access, especially in dense urban areas where shared living is common. The changes also support wider efforts to broaden access to clean energy options in Greece.
Adoption So Far
Data highlighted in reporting shows fast growth in small-scale self-consumption installations: between 2015 and 2019 Greece commissioned 1,772 systems totaling 36 MW, while since 2020 that number has risen to 37,407 systems with combined capacity of about 1,070 MW (source: CEEnergyNews).
The reforms are currently at the proposal stage after a recent public consultation. If adopted, they would combine technical rules (safety and non-export provisions) with administrative reforms (smart meters and an electronic registry) intended to streamline adoption and monitoring.
