For operators of commercial and agricultural PV systems
Whether you should clean your PV system yourself or have it professionally cleaned depends primarily on the size, accessibility, and degree of soiling of the system. For small, easily accessible systems, self-cleaning may be sufficient. For commercial, industrial, or hard-to-reach systems, professional cleaning is usually the safer and more economically sensible solution. Clean solar modules are crucial for high energy yield. Contaminants such as dust, pollen, or bird droppings can significantly reduce performance and impair the system’s efficiency in the long term.
In principle, self-cleaning is possible if certain requirements are met:
In these cases, careful cleaning with suitable equipment can be a cost-effective solution.
Self-cleaning
Professional cleaning
The decision depends on several factors:
The cleaning interval also plays an important role: systems that need to be cleaned regularly benefit particularly from efficient, professional solutions.
→ How often should a solar system be cleaned?
In addition, cost-effectiveness should be considered: whether cleaning is worthwhile depends heavily on the costs and the potential additional yield.
“Whether a PV system can be cleaned by the operator depends primarily on its size, accessibility, and the on-site safety conditions. For larger or hard-to-reach systems, safety should always take priority over potential cost savings.”
The decision between self-cleaning and professional cleaning depends heavily on the system’s individual conditions.
For small, easily accessible systems, self-cleaning may be sufficient. In most commercial, industrial, and agricultural applications, however, professional cleaning is the significantly more efficient, safer, and more economically sensible solution.
Our recommendation: Have your system assessed individually. Factors such as location, sources of soiling, and system size determine which cleaning strategy delivers the best results in the long term. Sound advice helps avoid risks and sustainably improve the system’s cost-effectiveness.
Whether it’s an agricultural rooftop system, a commercial roof or a large solar park—the economically optimal cleaning solution depends on system size, location and degree of soiling. Together, we analyze your system and recommend the right cleaning concept.
