Randstad: specific conditions for solar panels

The Randstad includes the urban core of the Netherlands: Amsterdam, Rotterdam, The Hague and Utrecht and the areas in between. With the highest traffic density in the country, two major ports and Schiphol airport, solar panels there receive an exceptionally high load.

Local factors affecting returns

Motorway network A2, A4, A12 and A20: the Randstad motorway network is among the busiest in Europe and emits exhaust particulates quasi continuously.
Ports of Rotterdam and Amsterdam: petrochemicals, container transhipment and refineries in Pernis, Westpoort and the Maasvlakte produce dense industrial output.
Schiphol: the airport and the approach routes put paraffin precipitation and exhaust particles on a large part of Randstad's rooftops.
Westland greenhouse construction: the Westland and Aalsmeer area deliver pollen, crop protection residues and lint that adhere to a damp panel.

What that means for your installation

In the Randstad region, we recommend two cleanings per year for most roofs, and even monthly servicing for large solar parks in industrial zones. We plan the rhythm according to your location and monitoring data.

Frequently asked questions about solar panel cleaning Randstad

Due to exceptionally high urban loads, we recommend two cleanings per year in the Randstad. On large commercial roofs in ports or close to Schiphol Airport, a quarterly maintenance rhythm can be cost-effective.

Rain washes off loose dust but leaves the typical Randstad mix of paraffin, petrochemical precipitation and exhaust particulates. So that layer is exactly what we thoroughly remove with osmosis water.

Yes. We clean private roofs in all Randstad cities as well as large industrial installations in the ports of Rotterdam and Amsterdam, at Schiphol Airport, at Shell Pernis, on the campuses in The Hague and Leiden and at greenhouse growers in Westland.

Customers in the Randstad typically see 12 to 28% yield recovery immediately after a thorough cleaning, with the highest gains on roofs in port areas or near Schiphol Airport. We link those figures back to your monitoring data.

We work throughout the Randstad, including in Amsterdam, Rotterdam, The Hague, Utrecht, Haarlem, Leiden, Delft, Zoetermeer, Almere, Schiedam, Vlaardingen, Capelle aan den IJssel, Amstelveen and Hoofddorp.
