Drenthe: specific conditions for solar panels

Drenthe is known for its open agricultural landscape, vast heathlands and growing numbers of solar parks. That context means that solar panels in this province have to deal mainly with agricultural dust, pollen from forests and heathland, and, increasingly, birds perching on solar farms.

Local factors affecting returns

Agricultural dust and crop protection: arable and dairy farming in the Hondsrug and the Drentse Plateau release soil dust, ammonia and spray residues into the air.
Heather and forest pollen: the forestries of Schoonloo, Gees and the Dwingelderveld yield plenty of pine, oak and heather pollen in spring and summer.
Bird droppings on solar farms: large solar farms attract seagulls, crows and pigeons, with localised patches on low-pitch modules.
Manure and barn emissions: intensive livestock farming around Coevorden and Emmen spreads ammonia and particulate matter that adheres to the glass.

What that means for your installation

In Drenthe, one annual cleaning is sufficient for most roofs, while solar parks and roofs near intensive livestock farming benefit from two turns per year. We tailor the schedule to the orientation and yield dates of your installation.

For homes in Drenthe, one thorough cleaning per year is usually sufficient. For solar parks and roofs near intensive livestock farming or large arable areas, we recommend two cleanings per year.

Rain washes off loose dust but leaves ammonia and manure precipitation plus fine pollen. That layer builds up just between showers and is responsible for the creeping yield loss we often measure.

Yes. We clean private roofs throughout Drenthe and large solar parks in Borger-Odoorn, Emmen and Coevorden, among others, plus company roofs on industrial estates in Assen, Hoogeveen and Meppel.
