Regional subsidies up to €1,500 + green certificates
Belgium benefits from an average solar irradiance of 1050 kWh/m2/year, making solar investment profitable within a few years.
With 1,050 kWh/m²/year of solar irradiance, Belgium offers higher solar potential than many realize. Flanders, Wallonia, and Brussels regions receive sufficient radiation for a payback period of 5 to 8 years. Modern technologies capture diffuse light effectively, performing well in cloudy weather.
The average electricity price in Belgium is €0.28/kWh in 2026, rising steadily for 5 years. Producing your own electricity protects you from these increases and reduces your grid dependency. Every kWh produced is a kWh you don't pay for.
By installing solar panels, you produce up to 70% of your annual consumption. With a home battery, self-consumption can reach 90%. You reduce your exposure to market fluctuations and contribute to Belgium's energy security.
A standard 4,000 kWh/year installation avoids approximately 0.7 tonnes of CO2 per year in Belgium. Over 25 years, that's the equivalent of planting more than 700 trees. Every installed panel contributes to national and European climate goals.
