Solar Panels: Produce and Use Your Own Electricity
Every day, your roof gets free sunshine. With well-designed solar panels, you turn it into electricity you use at home: less electricity to buy, and less worry every time energy prices go up. Add a home battery for the evening and a heat pump for heating and hot water, and your home runs largely on your own sun. Survey, installation, connection and follow-up: one point of contact from A to Z.

Why go solar now?
Solar panels are not just good for the planet: above all, they are a way to take back control of your electricity bill.
Use it at home
Every kilowatt-hour you produce and use on site is one you do not have to buy. What you send back to the grid earns you much less than bought-in electricity costs: the real gain is using it yourself.
Less exposed to price rises
Energy prices go up and down without asking you. The electricity from your own roof does not depend on the markets.
Sized for your home
We start from your actual consumption and your plans (heat pump, electric car) to install the right output, not too much and not too little.
The winning pair
Solar panels + heat pump: your sun heats your home
A heat pump heats your home and your water with electricity. With solar panels on the roof, a good share of that electricity comes from your own roof: heating and hot water become cheaper to run, and your production is used on site instead of going to the grid.
This is where solar really pays off. The heat pump can heat your hot water during the day, while the panels are producing, and warm the house up before the evening. In winter the sun produces less: that is why we design the whole system over the full year, so each appliance is the right size.
The same office surveys, installs and follows up your panels and your heat pump. No two companies passing the buck: one point of contact, one system designed as a whole.
What your sun can power
Heat pump
Heating and hot water partly powered by your panels. We design both together so neither one is oversized.
See heat pumps →Heat pump water heater
It heats your hot water while the sun shines: your production stored as hot water, ready for the evening.
EV charging point
Your car runs on electricity from your roof, especially at weekends or when working from home, with a charger that follows production.
Reversible air conditioning
It cools precisely when the panels produce most, and heats in spring and autumn.

A survey designed around your home
A good system is calculated before it is installed. The technician looks at the orientation and pitch of the roof, the shade from the chimney, a tree or the house next door at different times of day, the condition of the roof covering and the space available. A south-facing roof is not a must: an east-west roof produces earlier in the morning and later in the evening, which often suits family life better.
He then starts from your electricity bills: how much you use, when, and what is about to change, such as a heat pump, an electric car or a heat pump water heater. The aim is not to fill the roof, but to install the right output so you use as much of your own production as you can.
You receive a clear, itemised quote: panels, inverter, mounting, cabling, connection and paperwork. And if your roof is not suitable, we tell you plainly.
A careful installation, in one to two days
Installation starts with the roof, because keeping the roof watertight comes first. On tiles, hooks are fixed into the rafters and the tiles trimmed if needed; on slates, we use parts made for slate; on a flat roof, panels go on frames suited to what the roof can take.
Rails are lined up, panels clamped with the right clamps, cables tied and protected. Connectors are crimped with the tool made for their brand: a detail that prevents tomorrow's breakdowns. The job is done with safety equipment suited to your roof, and the site is left clean.
For a house, installation usually takes one to two days. Before leaving, the technician shows you where the cables run and where the inverter and isolators are.
Inverter, connection and commissioning
The inverter turns the current from the panels into electricity for the house. Depending on the roof, we choose a string inverter, optimisers on panels that get shade, or micro-inverters. With a hybrid inverter, a home battery can be added straight away or later.
It is connected to the consumer unit on a dedicated circuit with its own protection. Before commissioning, the system passes a conformity inspection by an inspection body and is registered with your grid operator (Sibelga, Fluvius, ORES or Resa depending on the region). We prepare the diagram and documents and help you with the paperwork.
At start-up, the technician sets up the monitoring app with you: you see what your roof produces day by day, and learn to run your big appliances at the right time.
Home battery: your sun, in the evening too
Around midday, your panels often produce more than the house uses. A home battery keeps that surplus for the evening, when the family comes home, dinner is cooking and the heat pump or electric car needs energy. The result: you use more of your own electricity instead of sending it to the grid.
The technician works out the usable capacity from your consumption, not from the biggest battery in the catalogue. It can be planned from the start or added later: we first check whether your inverter allows it, and tell you honestly whether it makes sense for you.
Some systems keep part of the house powered during a power cut: we tell you whether that is possible with your installation.
Solar panel and inverter repairs
Has your production dropped, is the inverter showing an error code or a red light, has the app stopped receiving data, or does the RCD trip when it rains? Every day it is down is electricity you have to buy back. Write down the message and the inverter brand, take a photo and call us.
On site, the technician checks the protection devices in the consumer unit, the inverter and its error log, then the panel strings one by one. He explains what he found and gives you the price of the repair before doing it.
We also repair systems installed by another company, all brands. If the inverter is too old, we suggest a replacement that suits your panels, with a home battery if the time is right.
Servicing and cleaning: keep all your production
Solar panels need little maintenance, but not none. Next to a field, a road, trees or under pigeons, a layer builds up and production drops without you noticing. Cleaning is done with soft water and a soft brush, never with a pressure washer.
During a service, the technician also checks the mounting, cables and connectors, the inverter and the protection devices in the consumer unit, and compares production with previous years. A slow decline often goes unnoticed without this check.
For your safety, do not climb onto the roof or touch the cables: a panel in the sun produces voltage even when the inverter is switched off.

Frequently asked questions
Are solar panels still worth it?
Yes, especially if you use the electricity you produce yourself: every kilowatt-hour used on site is one you do not have to buy. That is why we size the system from your consumption.
Do solar panels and a heat pump work well together?
Yes. A heat pump runs on electricity: with panels, part of that electricity comes from your own roof, and your production is used at home. We design both together, over the full year.
Is my roof suitable for solar panels?
It depends on the orientation, pitch, shade and condition of the roof. A south, east or west-facing roof can work. The technician comes to look and tells you honestly whether it is worth it.
How many panels do I need?
The number is worked out from your consumption and your plans (heat pump, electric car). The idea is to use as much of your own production as possible, not to fill the roof.
Do I need a home battery?
Not always. It is useful if you mostly use electricity in the evening, or have a digital meter, a heat pump or an electric car. We work out whether it makes sense for you; it can also be added later.
Are there grants for solar panels?
Support may exist depending on your region (Brussels, Wallonia or Flanders) and your situation, and the rules change often. We explain the steps and the documents you need, without promising any amount.
Does the installation need to be inspected?
Yes. Before commissioning, a solar PV system passes a conformity inspection by an inspection body and is registered with the grid operator. We prepare the documents and guide you.
Do solar panels need cleaning?
Rain is often enough. If a layer of dirt builds up, cleaning with soft water and a soft brush brings production back up. Never use a pressure washer or harsh products.
Do you repair panels installed by another company?
Yes, all brands. Write down the inverter message and brand, and call us on 0477 03 88 98: we will tell you when a technician can come.
How long does installation take?
For a house, installation usually takes one to two days. The final connection follows the conformity inspection and the registration with the grid operator.
