Estimate your solar output in Namur from local irradiance (1050 kWh/m²/year) and compare quotes from certified installers. Free, no obligation.
Any surplus you do not consume is fed into the grid, according to the scheme in force in your region.
Payback time depends on your consumption, roof orientation and the subsidies in force: we calculate it for your address.
A photovoltaic installation improves the property's energy performance certificate (EPC), which is mandatory information when selling or renting.
In Wallonia there is no longer any regional grant for a new residential photovoltaic installation: the Region stopped supporting this sector on 1 July 2018 (end of Qualiwatt).
The prosumer tariff is a network cost, not a subsidy: it has been charged to producers since 1 October 2020 and lengthens payback. The reverse-running meter only remains for installations fitted before 31/12/2023.
