The costs for professional PV cleaning usually range between €1 and €3 per square meter for commercial and industrial systems.
However, the price alone is not the decisive factor, but rather the loss of performance due to soiling: In many cases, cleaning is economically viable from a yield loss of around 10–15%.
For typical systems, this means:
Since commercial systems are often cleaned once or twice a year, the question of economic efficiency arises regularly.
The decisive rule of thumb is: Cleaning is always worthwhile if the annual yield loss is higher than the cleaning costs.
Photovoltaic systems are permanently exposed to environmental influences. Particularly in agriculture, commerce, and on large roof areas, deposits are caused by:
This soiling reduces the light transmittance of the modules and leads to:
The problem: Performance drops gradually and often remains unnoticed for a long time, while the economic loss increases continuously.
The central decision rule is:
PV cleaning is worthwhile if the yield loss is higher than the cleaning costs.
Practical example:
Additional benefits:
Whether PV cleaning is economically viable depends directly on the ratio between yield loss and cleaning costs. Even with soiling of around 10–15%, cleaning can pay off in many cases – especially for large commercial systems.
With typical costs and potential performance losses of up to 30%, practice often shows that the additional electricity yield exceeds the cleaning costs.
The actual costs depend on several factors:
Especially for large commercial and agricultural areas, the price per square meter drops significantly.
For farmers, medium-sized companies, and industry, the following applies:
PV cleaning is not a pure cost factor, but an investment in the system’s yield.
Those who ignore soiling lose performance continuously.
Those who clean systematically secure the long-term economic efficiency of their photovoltaic system.
