Why choose Avenir Renovations?
Why choose solar energy today?
More and more households want to face rising energy prices while participating in the ecological transition.
A growing dependence on the electrical grid
Electricity prices keep increasing. Producing your own energy becomes an effective way to control long-term expenses, especially for high-consumption households (electric vehicle, heat pump, appliances).
Thanks to self-consumption, you reduce the impact of price increases while improving your energy autonomy.
A desire to reduce carbon footprint
Solar panels can cover a significant part of your energy needs without CO₂ emissions while increasing your property's value upon resale.
A home equipped with solar panels benefits from a better energy performance score and becomes more attractive on the real estate market.
An underutilized roof
Many homes have a well-oriented but unused roof. Installing solar panels transforms a passive surface into a profitable production tool, even without complete self-consumption.
Even a roof oriented east or west can produce satisfactory yields, thanks to efficient inverters or a multi-oriented system.

FAQ – solar panels in Belgium
Are solar panels profitable in Belgium?
Yes. Even with the evolution of the compensation system (end of the reverse meter), solar panels remain profitable on average in 6 to 9 years. In Wallonia, green certificates and an investment grant can reduce the purchase cost. In Brussels, a grant (Renolution) and resale of surplus allow for a quick return on investment. Additionally, your property increases in value.
Can I consume the energy produced immediately?
Yes. With a self-consumption system, you directly use the electricity produced in the house: appliances, electric heating, heat pump, etc. You can also install a storage battery to extend autonomy in the evening or during cloudy days.
Is a building permit required to install panels?
Generally, no. Installation on a sloped or flat roof, outside classified areas, does not require a permit. However, in some cases (facade, protected area, classified property), a declaration may be required. We check these points with you during the technical visit.
What happens in case of a power outage?
Without a battery, the panels do not provide electricity during an outage, as they are connected to the grid. With a backup battery or a hybrid system, you can continue to power certain circuits. We advise you on the best options based on your setup.
