How often should solar panels be cleaned?

We recommend cleaning solar panels at least 1-2 times a year. In areas with heavy pollution (near motorways, industrial sites or under trees), more frequent cleaning may be needed.

How much output can dirt reduce?

Dirty solar panels can generate up to 25-30% less energy. Dust, pollen, bird droppings and leaves form a layer that blocks sunlight. Professional cleaning makes an immediate difference to your output.

Can cleaning damage solar panels?

Not with professional cleaning! We use only demineralised water without chemicals and soft brushes. Our method is completely safe and recommended by panel manufacturers.

Do you also clean solar panels on flat roofs?

Yes, we clean solar panels on all roof types: pitched roofs, flat roofs and carports. Our equipment suits a wide range of situations.

Do I need to be home during cleaning?

Not necessarily, as long as we can access the panels. We agree on arrangements in advance and let you know when the work is complete.

Why have your solar panels cleaned?

Solar panels are a smart investment, but only when they perform at their best. Dirt, dust, pollen and bird droppings block sunlight and reduce output. In Belgium, dirty panels can generate up to 25-30% less energy.
