More efficiency with the right brush
For operators and professional PV cleaners
The PV brush width significantly determines how efficiently and thoroughly you clean your solar system. At the same time, it directly influences the surface performance and the quality of the cleaning. In this article, you will therefore learn which brush width is best suited for your system and how to make your cleaning more efficient. Further technical details and background information can be found in our specialist article “The perfect PV cleaning device – The right solution for your solar surface”.
PV brush width determines how efficiently, evenly, and with how much control you clean your system.
With the right brush width, you not only clean large areas faster but also maintain the necessary precision. Furthermore, you improve control over the brush and reduce the physical effort required. If, on the other hand, you choose a brush that is too wide, you lose control more quickly and have to use more force. If the brush is too narrow, you increase the time required because you have to perform more cleaning passes.
Only when you optimally coordinate working width and handling will you achieve a uniform cleaning result with minimal effort. Especially with different types of systems, it becomes clear how much the brush width influences your efficiency.
If you choose the wrong PV brush width, you not only lose time but also reduce the cleaning quality.
If the brush is too narrow, you have to clean significantly more lanes to cover the entire module area. This not only increases the time required but also the physical strain, as more movements are necessary. Especially with larger systems, this additional effort adds up considerably and thus directly affects the cost-effectiveness of the cleaning.
If, however, the brush is too wide, you lose control, especially on rooftop systems, edge areas, or angled surfaces. This increases the risk of areas being cleaned unevenly or even missed. In addition, the greater weight and stronger leverage increase the physical effort, making handling more difficult and further reducing precision.
In practice, an unsuitable brush width often means you have to compromise between speed and quality – resulting in neither efficiency nor cleaning results being optimal.
"When it comes to brush width, it's not automatically a case of: the wider, the better. The crucial factor is the balance between surface performance, control, and handling – and thus the question of which brush suits the respective system."
| Brush Width | Typical Benefit |
|---|---|
| Narrow Brush | Enables precise work and maximum control, especially for small or angled rooftop systems |
| Medium Brush | Offers a balanced combination of efficiency and handling and can be used flexibly for different types of solar systems |
| Wide Brush | Maximizes surface performance while saving time, especially for large and easily accessible systems |
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.
