Why cleaning solar panels in Harmelen is worthwhile
Cleaning solar panels in Harmelen immediately ensures maximum yield. Did you know that a thin layer of dust, pollen, or bird droppings can reduce the efficiency of your PV panels by tens of percent? In practice, the effect of pollution is significant. According to Google's Knowledge Graph, pollution blocks sunlight, reducing its conversion into energy. In Harmelen, with its mix of urban areas, abundant green spaces, and agricultural businesses, every panel will eventually be exposed to deposits such as algae, moss, smog, or even local industrial particles. By keeping solar panels clean, you optimize their lifespan and performance.

Cleaning company Groene Hart uses reverse osmosis water and soft brushes, using techniques established by industry organizations like the Cleaning Research Association (VSR).
We know how to guarantee safety and are familiar with the installation and warranty conditions. Damage caused by cleaning yourself is often excluded from the manufacturer's warranty. Professional cleaning ensures clean and optimally performing panels, thanks to the use of skilled personnel and scientifically proven methods.
Do clean solar panels actually increase your returns?
Absolutely! Various studies, including those by TNO and Utrecht University, show that contamination on your panels can cause a loss of efficiency of up to 20 percent. Dust, pollen, and moss form a thin layer, which reduces the amount of sunlight your panels absorb.
After a professional cleaning, you will see results on your energy meter almost immediately. Every summer, our customers notice that an annual cleaning makes a big difference in yield. Would you like more tips for better solar power usage? Visit our experts in Woerden for additional advice.
