Installation of storage batteries paired with your solar system in Brussels (1000) and across the 19 municipalities, from the Pentagon to the residential districts of Uccle and Ixelles. A Brussels-based team, a free self-consumption study scheduled within 48 hours and installation in a single day. We size the battery to maximise your self-consumption and add a back-up function in case of an outage — on new installations as well as on existing photovoltaics.
We install storage batteries in Brussels across the 19 municipalities, with a team that knows the capital’s building stock — from the townhouses of the Pentagon to the flat-roofed buildings of the Louise district, by way of the villas of Uccle and the terraced houses of Ixelles. Most of our projects pair the battery with an already installed photovoltaic system.
The self-consumption study is carried out at your home, with no call-out fee and scheduled within 48 hours : we analyse your solar production and your consumption profile, then size the most cost-effective battery capacity. The same team then installs the battery in a day, configures the back-up function and handles commissioning.
We know Brussels buildingsBeyond the Pentagon, we also install storage batteries in Laeken, Saint-Gilles, Etterbeek and Forest, as well as towards Uccle, Ixelles and Schaerbeek — same team, same lead times across the whole Region.
Brussels relies on the incentives of the Brussels-Capital Region. Here are the levers we leverage to make your battery pay off, paired with your solar production.
In Brussels, green certificates are granted on the production of your photovoltaic system. The battery does not generate certificates on its own, but by storing your surplus it makes every kWh produced and paired more valuable. We handle the solar application with Brugel.
For a home over 10 years old, VAT drops from 21 % to 6 % on the supply and installation of the battery paired with your system. Applied directly to your quote.
We calculate the ideal battery capacity based on your consumption and your solar production : neither too large (needless extra cost), nor too small (surplus fed back to the grid). The goal is to maximise your self-consumption and cut your bill.
The details of amounts, capacities and payback assumptions can be found on our storage price & payback page. We price the battery and its solar pairing in a clear quote, with no obligation.
A few recent battery installations in Brussels and its municipalities. Each project is handled by the same team, from the self-consumption study to commissioning.
Addition of a 10 kWh battery to an existing 5 kWp photovoltaic system. The daytime surplus is now stored and consumed in the evening : self-consumption raised from 35 % to over 70 %.

« Ajout d'une batterie à notre installation solaire existante. Le dimensionnement était juste, on consomme désormais le soir notre propre énergie. »
From the home battery to solar storage and lithium modules, we tailor the solution to your production and your consumption. Explore each range :
Modular residential batteries, sized to your consumption to maximise self-consumption. Discreet installation in a cellar, garage or utility room, with real-time monitoring.
Discover the batteries →Pairing the battery with your photovoltaic system, new or existing, to store the daytime surplus and consume it in the evening. The heart of payback in the city.
See solar storage →High-density lithium technology : compact capacity, long lifespan and many charge cycles. The best compromise for Brussels homes where space is at a premium.
Explore lithium →It depends on your daily consumption and your panels’ production. For an average Brussels household with a 4 to 6 kWp system, a 5 to 10 kWh battery is often enough to cover the evening. Our free self-consumption study measures your real profile and proposes the most cost-effective capacity, without oversizing.
In the vast majority of cases, yes. We add a battery compatible with your already installed photovoltaic system, whether recent or older, adapting the inverter if needed. It is in fact our most common project in Brussels : the study checks compatibility before any quote.
Yes, if you wish. We configure the battery in back-up mode : during a grid outage, it automatically powers your essential circuits (lighting, fridge, internet box). It is a valuable asset in the dense urban fabric of Brussels. This function is defined together at the time of the study.
A battery clearly increases your self-consumption : instead of feeding your daytime surplus back to the grid, you store it to consume in the evening, when electricity is most expensive. The more your consumption falls outside production hours, the more cost-effective the battery is. The study calculates your payback before any commitment.
Yes, completely : the visit to your home in Brussels, the analysis of your solar production and your consumption, the battery sizing and the costed quote are free and with no obligation. You pay nothing until you have approved your project.
