Consider a plug-in balcony solar panel
Since 17 April 2025, plug-in solar panels are allowed in Flanders; the government advises keeping the inverter below 800 W. They suit tenants who cannot install a full system.

Rules from the Flemish government: keep the inverter below 800 W, use an inverter on the Synergrid approved list, plug directly into a wall socket (no extension cord or power strip) on a circuit without other heavy appliances, and mount the panel securely. With a digital meter and under 800 W you don't need to register; Fluvius detects it. With an analogue meter, register with Fluvius within 30 days. From 800 W upwards you must always register within 30 days, whatever meter you have. No permit is needed for balconies or façades, except on protected heritage.
To see what a panel could produce on your balcony, enter its direction and tilt in the EU's free PVGIS tool. It shows production only, not how much of it you will use yourself.
Ask your landlord before fixing anything to the façade or balcony, and check your home insurance. No citation The panel is a loose, movable device, so you can take it with you when you move.
