EPDM Daken Slopen

1. Before Conditions:
Jeroen contacted us regarding reduced energy output from the solar panels on his apartment roof in Amsterdam. Upon inspection, we found a thick layer of dirt, bird droppings, and moss buildup that had accumulated over time, significantly blocking sunlight.

2. Our Calculation:
We conducted a site survey and estimated 12 panels needed a thorough cleaning. Based on our transparent pricing model, we calculated the total service cost at €25 per panel, including access equipment and safety measures, totaling €300.

3. How We Did:
Our expert team used demineralized water and soft-bristle brushes to clean the panels without damaging the surface. Safety was prioritized throughout, using roof harnesses and weather-appropriate scheduling.

4. Conclusion:
After cleaning, the panels were restored to optimal performance, increasing efficiency by an estimated 15–20%. Jeroen was highly satisfied with the professional service and noticeable improvement in output.
