Balcony solar for Athens apartments
Cut your electricity bill from your balcony. Balcony solar is now legal in Greece (Gazette B 5573/2026). Reservations are open, and Athens installs start once DEDDIE publishes its safety specifications (due by 31 October 2026).
Short answer
Balcony solar in Athens lets apartment owners and tenants generate electricity directly from the balcony, without needing a rooftop. Sunrail is built for urban apartments, with ready Basic, Smart, and Max packages, Athens installation, and compliance review under Greek rules. With Smart, savings are about €245–315 a year at €0.22/kWh, depending on orientation, shade and usage.

Check before installation
The decision requires an engineer's or installer's declaration, an active YDE on your supply and a notification to DEDDIE. Before we move ahead, we check your balcony, your supply and whether your area accepts new connections.
Athens installation for €99. Before the final quote, we review the balcony photo, shade, mounting space, and cable route so we can recommend the right setup.
Reserve the package you want
Send your details and, if you want, a balcony photo. We review the space, estimate likely payback, and send you a quote with the setup that fits your balcony.
- Reservation is refundable if the balcony is not suitable.
- Final price and equipment are confirmed in the quote.

Questions, answered
Yes. Ministerial decision YPEN/DAPEEK/102876/1958/2026 (Government Gazette B 5573, 14 Sep 2026) allows balcony solar up to 800 W output and 1,000 W installed, for self-consumption. Installs are allowed once DEDDIE publishes its safety specifications, due by 31 October 2026.
After DEDDIE publishes its safety specifications (due by 31 October 2026). The notification goes through a DEDDIE digital portal whose start date is due by 31 December 2026. If you reserve now, we review your balcony so you are ready.
No. Sunrail is designed for apartment balconies and terraces.
Not always. A battery is more useful when you are away during the day or use more power in the evening.
Usually yes, because the system is portable. If it changes the exterior, requires drilling, or your building rules require approval, get written permission before ordering.
Shade reduces output, especially around midday. That is why we ask for a balcony photo and orientation before recommending a package.
The packages are estimated for self-consumption: the value comes from power you use at home. We do not count unused surplus as income in the savings estimate.
A typical balcony installation is completed in one day once the space, mounting route, cable path, and process have been confirmed.
