Plug-in Solar Panels Now Legal and Easy to Use in Flanders
Since April 17, 2025, plug-in solar panels are officially legal in Flanders. Residents with a digital meter can now use plug-in solar panels and home batteries without registering them with the grid operator, Fluvius. This follows Belgium’s recent decision to approve these compact and user-friendly systems for sale and use.
Plug-in Solar Panels: A Simple Solution for Renters and Apartment Dwellers
Already popular in Germany and the Netherlands, plug-in solar energy is ideal for people who can’t install traditional rooftop systems. Renters and apartment residents now have access to clean energy at home. These systems require no tools or professional installation—just plug them into a standard socket and you’re good to go.
Rules and Limits in Flanders
To protect the power grid, households in Flanders can only install up to two plug-in units. Each inverter must stay under 800 watts. Fluvius will monitor this rule. If a household goes over the limit, they risk a fine starting at €92.79.
Earlier, authorities said these systems might need to be registered, just like larger solar installations. But the Flemish Energy and Climate Agency confirmed: no registration is required for plug-in systems. This differs from Wallonia, where residents still need to report them.
Larger solar setups must still be declared. Fluvius needs this data to manage electricity flow and keep the network balanced.
