Gelderland: specific conditions for solar panels

Gelderland stretches from the Veluwe and the Rivierengebied to the Arnhem-Nijmegen urban axis. This diversity explains why solar panels there face very different pollution sources: forest pollen on the Veluwe, river mist along Waal and IJssel and industrial precipitation around Arnhem-Nijmegen.

Local factors affecting returns

Veluwe poles: vast coniferous and deciduous forests yield significant amounts of pine, oak and birch pollen in spring and summer.
River fog Waal and IJssel: river valleys cause frequent morning fog that leaves dirt on the panel for longer and promotes algae formation.
A12, A50 and A15 traffic: these busy connections create continuous exhaust fine dust, especially on rooftops in Ede, Zevenaar, Tiel and Nijmegen.
Horticulture and greenhouse farming: in the Rivierengebied and around Bemmel-Huissen, greenhouses and fruit crops release pollen, crop protection and soil dust into the air.

What that means for your installation

In Gelderland, we recommend one annual cleaning for most roofs, with a second turn for installations close to highways, in the Liemers region or in horticultural areas. We plan the schedule according to your orientation and monitoring data.

Frequently asked questions about solar panel cleaning Gelderland

For homes on the Veluwe and in urban centres, one annual turn is usually sufficient. Roofs in the Rivers region, near highways or in horticultural areas usually benefit from two cleanings per year.

Rain washes away loose dust but the fine mix of forest pollen, paraffin precipitation and crop protection remains. River mist in the IJssel valley further enhances that effect by keeping dirt moist for longer.

Yes. We clean homes throughout Gelderland and large company roofs at the logistics parks Park15 and Westas, on the campuses around Wageningen, and at horticultural companies in Bemmel, Huissen and Tiel.

Customers in Gelderland typically see 8 to 22% yield recovery after a thorough cleaning, with outliers in horticultural areas and near the A12 and A50. We compare those gains using your monitoring data.

We work throughout Gelderland, including in Arnhem, Nijmegen, Apeldoorn, Ede, Tiel, Doetinchem, Zutphen, Harderwijk, Wageningen, Zevenaar, Culemborg, Winterswijk and Lochem.
