Greece to Allow Balcony Solar Panels for Cheaper Home Electricity

Greece is set to make it easier for citizens to generate their own electricity with new regulations for "self-consumption" of energy. The Ministry of Environment and Energy is launching a public consultation for a ministerial decision that will allow individuals to install small photovoltaic systems, commonly known as solar panels, on their balconies.

These new systems will have a capacity of up to 800 watts for home use and can include battery storage. Crucially, the energy generated is strictly for personal consumption and cannot be fed back into the national grid. This initiative aims to promote the development of renewable energy sources and provide access to cheaper electricity for households.

To ensure safety and grid stability, the new framework includes stringent safeguards. Consumers must declare the installation details to their supplier or installer, who will then inform the grid operator. A digital portal, accessible via government credentials, will be used for registration at least five days before installation. The system will require an installer's declaration, a direction sensor to prevent energy injection into the grid, and a telemetry system to monitor production and consumption.

Notably, these installations will not require a connection agreement with the grid operator or any additional permits or fees. The maximum installed capacity per consumption point is capped at 800 watts, or 900 watts for the system itself. The grid operator will also publish specific technical requirements for installation and operation in collaboration with the Hellenic Organization for Standardization.
