By using rooftops, Belgium could increase its PV installations sixteenfold

The Belgian institute EnergyVille has just compiled a list of Belgium's rooftop photovoltaic and onshore wind power potential. It arrives at a total volume of 118 GW (99.6 GW solar + 18.2 GW wind). Flanders has the largest rooftop solar potential with 65 MW; Wallonia has 30 GW and Brussels has 4 GW. At the end of 2020, Belgium had an installed capacity of 6 GW, almost exclusively residential and commercial solar.

These figures require the use of photovoltaic panels of 226 Wp per m², with a specified tilt and orientation per building type, while Belgium has between 930 and 1,060 hours of full load sunshine. This would produce 99.3 TWh per year.

Editor's note: This means that Belgium could install more than 16 times the current solar capacity by using only the roofs. This would leave the ground surfaces untouched
