Below is the average daily output per kW of Solar PV installed for each season, along with the ideal solar panel tilt angles calculated for various locations in Belgium. Click on any location for more detailed information.

Explore the solar photovoltaic (PV) potential across 184 locations in Belgium, from Turnhout to Arlon. We have utilized empirical solar and meteorological data obtained from NASA's POWER API to determine solar PV potential and identify the optimal panel tilt angles for these locations.

Feel free to contact us if you wish for us to include a general Solar PV Analysis for a certain city or location not already listed here for Belgium. We will be more than happy to manually add it for you.

Solar Panel Tilt Angle in Belgium

So far based on Solar PV Analysis of 184 locations in Belgium, we've discovered that the ideal angle to tilt solar PV panels in Belgium varies between 44° from the horizontal plane facing South in Turnhout and 42° from the horizontal plane facing South in Arlon.

These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).

Depending on where you are based in Belgium, the ideal angle to tilt your solar panels will vary by approx 2 degrees (between 44° from the horizontal plane facing South and 42° from the horizontal plane facing South).

Belgium solar PV Stats as a country

Belgium ranks 19th in the world for cumulative solar PV capacity, with 6,585 total MW's of solar PV installed. This means that 6.60% of Belgium's total energy as a country comes from solar PV (that's 10th in the world). Each year Belgium is generating 569 Watts from solar PV per capita (Belgium ranks 5th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Belgium?

Yes, there are several incentives for businesses wanting to install solar energy in Belgium. The Belgian government offers a range of financial support measures for businesses that invest in renewable energy sources such as solar power. These include tax deductions, grants and subsidies, as well as access to low-interest loans. Additionally, the Flemish Energy Agency (VEA) provides free advice and guidance on how to make the most of these incentives.
