Flemish Brabant: specific conditions for solar panels

Flemish Brabant stretches from the Brussels periphery with Zaventem to the Hageland and Pajottenland. As a result, solar panels here combine the influence of Brussels Airport, the Ring R0 and intensive arable farming in a relatively limited area.

Local factors affecting returns

Brussels Airport Zaventem: air traffic and associated ground operations spread paraffin deposits and particulate matter in a radius around Zaventem and Steenokkerzeel.
Ring traffic R0 and E40: the Brussels Ring Road and the E40 together form one of Belgium's busiest traffic axes with continuous exhaust deposition.
Hageland farming: vineyards, fruit growing and arable farming in the Hageland bring soil dust and pollen into the air, especially in spring and autumn.
Pollen Sun Forest: the vast Sonian forest and the forests around Tervuren and Overijse yield large quantities of beech and oak pollen.

What that means for your installation

For Flemish Brabant roofs, we recommend one to two cleanings per year. Installations close to Zaventem, along the Ring or in the middle of arable land usually see the highest yield gains after a second cleaning.

Frequently asked questions about solar panel cleaning Flemish Brabant

In the Brussels periphery and around Zaventem, we recommend one to two cleanings a year due to the combination of aviation and road traffic. In the Hageland and Pajottenland, one thorough cleaning is usually sufficient, with a second cleaning after an intense spraying or blossoming season.

Rain dissolves loose dust but leaves paraffin deposits, fine soot particles and crop protection residues. This mix is typical of Flemish Brabant and gradually builds up between showers.

Yes. We clean private roofs throughout Flemish Brabant and large commercial installations at Zaventem airport park, in Drogenbos, Diegem, Machelen and at logistics parks in Tienen, Aarschot and Halle.

Customers in Flemish Brabant typically see 9 to 23% yield recovery immediately after cleaning, with the biggest gains around Zaventem and on industrial roofs near the Ring. We link those gains back to your monitoring data.

We work throughout Flemish Brabant, including in Leuven, Vilvoorde, Tienen, Aarschot, Diest, Halle, Asse, Zaventem, Tervuren, Overijse, Grimbergen, Machelen, Liedekerke and Boortmeerbeek.
