Solar panels · Cleaning
More sunlight captured.
More power produced.
Dust, pollen, pollution, bird droppings: dirt builds up and rain alone won't wash it off. A dirty panel captures less light and produces less electricity. Regular cleaning maintains output and extends the system's lifespan.

How often
Depending on your roof pitch.
1×/year
Roof pitched at 15% or more, in a fairly wet area. Rain helps, but leaves pollution residue and fine particles.
2×/year
Pitch under 15% or a dry area. Ideally in early spring, after the snow, and in autumn, after the pollen season.
For large systems and business installations, more frequent cleaning can be scheduled.
The environment matters
Every roof gets dirty differently.
In town
Near busy roads: fine particles and pollution.
In the countryside
Ploughing and harvests: pollen and farm dust.
In the mountains
Melting snow leaves residue and marks.
