Solar panels that truly produce, fitted everywhere in Belgium

Everything to understand before going solar

Installing photovoltaic panels means producing part of your own electricity and taking back control of your bill. On a well-exposed Belgian home, the roof becomes a small power plant working for you on every day of light — and even under cloudy skies, the yield stays real. But a good installation cannot be improvised: it all comes down to sizing and to the share you consume yourself.

“The smart move is no longer to sell back to the grid, but to consume as much of what you produce as possible — that is where the real savings are made.

The ideal capacity is not the biggest one possible, but the one that matches your usage. Too small and you stay dependent on the grid; too big and it produces a surplus that is poorly rewarded. Here are the options to consider depending on your profile:

• Monocrystalline Most common

  Excellent yield even under cloudy skies. The Belgian standard today.

  Panel types →
• With a battery More independence

  Use in the evening what you produce by day. Ideal under the prosumer tariff.

  See storage →
• Plug-and-play kit Small budget

  A reduced upfront outlay to produce your first kWh without a big job.

People often look at the panels, but it is the inverter that turns direct current into usable power and runs the whole system. Central inverter or micro-inverters: the choice depends on the shading on your roof and how the panels are laid out. We explain the concrete impact on your production.

A wendows adviser helps you weigh up capacity, storage and budget — without needless jargon, just as our one stop shop approach intends.

With the gradual end of the meter that runs backwards and the prosumer tariff, storing your energy makes sense. A home battery lets you use in the evening the electricity produced in the afternoon, instead of feeding it back at a low price. Not everyone needs one: we compare both costed scenarios before deciding.

Residential installations benefit from reduced 6% VAT for homes more than ten years old, and depending on your region further grants may apply. The return on investment depends above all on your self-consumption.

A well-fitted installation is watertight, correctly oriented and connected to standard. Monitoring shows you production day to day, and our after-sales service stays reachable over time for the smallest adjustment.

If you are electrifying your heating too, solar pairs perfectly with a heat pump: you heat with your own energy. Live in a big city? Our solar panels in Brussels, in Liège or in your municipality pages detail local grants and references.
