Why solar panel cleaning is important
Many people think that rain washes the panels clean by itself, but stubborn dirt often gets stuck. Think of bird droppings, fine dust, leaves and algae. This causes shadow spots and has a direct impact on the energy yield.
“On average, a clean solar panel provides 10-20% more energy than a dirty panel.” - Hendrik (Solarco)
Regular cleaning also helps prevent premature wear and tear and extend the life of your installation. In other words, cleaning is not a “cost” but an investment in return.

Is solar panel cleaning financially interesting?
A 4.8 kWp installation produces an average of 4,500 kWh per year.
5% yield loss = 225 kWh loss.
At €0.35/kWh, that means €78 loss per year.
So a €125 cleaning will quickly pay for itself.

How Often Do Solar Panels Need Cleaning?
The frequency of cleaning depends on the location and surroundings of the panels. Here are some guidelines:
- In urban areas: once a year (due to air pollution and dust)
- In agricultural areas: 2 times a year (due to dust, mud and manure)
- In coastal areas: 2 times a year (due to salt accumulation)
- At solar farms and industry: Every 3 to 6 months (due to heavy soiling)
Regular cleaning prevents yield loss and extends the life of your solar panels.
