Our local presence

Wendows in Brussels

We install solar panels in Brussels across the 19 municipalities, with a team of installers who know the capital’s building stock — from the master houses of the Pentagon to the flat-roofed buildings of the European Quarter, from the terraced rows of Schaerbeek to the villas of Uccle.

The solar survey takes place at your home, with no travel charge and scheduled within 48 hours ; we calculate the expected output, size the system and prepare your green certificate file. The same team then follows the whole project, from survey to installation and commissioning.

We know Brussels rooftops
Master houses with pitched roofsSloped roofs of traditional Brussels townhouses: we favour the south and south-west pitches to maximise output on surfaces that are sometimes narrow.
Flat-roofed buildingsOn the flat roofs of apartment blocks and extensions, we install panels on tilted ballasted trays, without piercing the waterproofing, oriented for the best yield.
Listed zones & street-facing façadesWithin protected perimeters and the historic centre, street-side panels are often restricted : we then install on the rear pitch, discreet and compliant with planning rules.

Beyond the Pentagon, we also install solar panels in Laeken, Ixelles, Saint-Gilles and Etterbeek, as well as towards Uccle, Schaerbeek and Anderlecht — same team, same timelines across the whole Region.

Grants & incentives

Your incentives for solar panels in Brussels

Brussels relies on the support schemes of the Brussels-Capital Region. Here are the levers we set up and leverage to make your installation pay off, with nothing for you to do.

Green certificates

Brussels green certificates

In Brussels, green certificates are granted for around ten years based on the output of your photovoltaic system. We prepare the entire file and handle the declaration with Brugel.

6 %VAT

Reduced VAT for renovation

For a home over 10 years old, VAT drops from 21 % to 6 % on the supply and installation of the panels. Applied directly to your quote.

Self-consumption

Maximising self-consumption

We size the system to match your needs and offer an optional storage battery, so you consume as much of your own production as possible and cut your bill.

2026 benchmarks — indicative amounts, to be confirmed based on your file.

The details of amounts, conditions and output assumptions are on our solar panel price & incentives page. We prepare the entire green certificate file : you fill in no forms.

Frequently asked questions

Solar panels in Brussels — your questions

Are solar panels worth it in Brussels?

Yes. Despite the dense urban fabric, Brussels rooftops deliver good yields when well oriented and lightly shaded. Our free solar survey precisely measures the expected output at your home, taking neighbouring buildings into account, before any commitment. Combined with green certificates and good self-consumption, the installation pays for itself within a few years.

How do green certificates work in Brussels?

In Brussels, green certificates are granted for around ten years based on the electricity produced by your photovoltaic system. They are an extra income that helps make the project pay off. We prepare the entire file and handle the declaration with Brugel : you fill in no forms.

My roof is listed or north-facing, is that possible?

It’s our daily routine in Brussels. In listed zones and the historic centre, street-side panels are often restricted : we then install on the rear pitch, discreet and planning-compliant. For an unfavourably oriented roof, the survey determines whether a south-east or south-west pitch, or a flat-roof installation with tilted trays, remains profitable.

Is a storage battery useful in Brussels?

A battery is not essential but it clearly increases your self-consumption : you store the surplus produced during the day to use it in the evening. It is especially worthwhile if you are rarely home during the day. We size the battery to your consumption profile and price the option in the quote, with no obligation.

Are the solar survey and the quote really free?

Yes, completely : the visit to your home in Brussels, the analysis of your roof, the output calculation and the priced quote are free and without obligation. You pay nothing until you have approved your project.
