Overijssel: specific conditions for solar panels

Overijssel stretches from the IJsselmeer and Hanseatic city of Kampen to the industrial cities of Twente and the Salland Ridge. That geography means that solar panels there face a distinct combination of machine industry, agricultural activity and forest foliage.

Local factors affecting returns

Twente machinery industry: in Hengelo, Almelo and Borne concentrates metalworking, mechanical engineering and chemistry, with fine metal particles as a by-product.
Agricultural activity Salland: arable and livestock farming around Raalte and Hardenberg spread ammonia, manure residues and soil dust.
Pollen Sallandse Heuvelrug and Twente forests: the vast natural areas produce significant amounts of pine and oak pollen in spring and summer.
Traffic A1 and N35: the main axis from the Randstad towards Germany creates exhaust fine dust on roofs in Deventer, Wierden and Hellendoorn.

What that means for your installation

For Overijssel roofs, we recommend one to two cleanings per year, with a second turn for installations on Twente industrial estates or close to intensive livestock farms. We tailor the schedule to your orientation and monitoring dates.
