Why is regular washing of photovoltaic panels crucial?
The cleanliness of photovoltaic panels has a direct impact on their energy efficiency. Even minor dirt can significantly reduce the amount of sunlight reaching the cells, resulting in a decrease in system productivity. Regular cleaning of the panels not only increases their efficiency, but also contributes to prolonging their life, providing owners with a better return on investment. Mansser offers professional cleaning services for photovoltaic panels, using the latest technologies and methods to maximize their efficiency and protect them from damage due to dirt accumulation.
How does dirt affect the performance of photovoltaic panels?
Dirt, dust, leaves, bird droppings and other contaminants deposited on the surface of photovoltaic panels can significantly reduce their performance. These contaminants block sunlight, preventing it from effectively reaching the solar cells. Studies have shown that even a light layer of dust can reduce the efficiency of panels by 5-10%, and in extreme cases, such as heavy dirt or leaf accumulation, the drop in efficiency can be as high as 25%. Regular and thorough cleaning of the panels is essential to maintain their maximum efficiency and ensure optimal energy production.


Professional cleaning methods for photovoltaic panels in Mansser
At Mansser, we use only specialized techniques to wash photovoltaic panels to ensure safety and efficiency without risking damage to delicate surfaces. We use demineralized water that does not leave streaks or lime deposits, which is key to keeping the panels clean and effective. Our teams use soft brushes and special eco-friendly cleaners that are safe for solar surfaces and the environment.
In addition, we work with telescopic systems, which makes it possible to thoroughly clean the panels even in hard-to-reach areas without having to climb onto the roof. Thanks to these methods, cleaning is not only effective, but also fast and does not interfere with normal plant operation. Regular professional cleaning of panels increases their life and efficiency, maximizing energy yields.
Optimal times of the year to wash panels
when and why?
Cleaning of photovoltaic panels should be carried out at least twice a year to ensure maximum energy efficiency. The best times to perform this service are early spring and late autumn.
Early spring is the ideal time to remove dirt that has accumulated over the winter, such as dirt, road salt and plant debris. Cleaning at this time prepares the panels to take advantage of the increase in sunlight in spring and summer.
Late autumn is the time when it's a good idea to remove leaves, small branches and other debris after the summer season, which can restrict sunlight during the shorter winter days.
In addition, it is worth remembering to avoid washing the panels in full sunlight, especially in summer afternoons when the panels are very hot. Washing hot panels can damage them due to the thermal shock caused by contact with cold water. The best time of day to wash is early morning or late afternoon, when the sun is less intense.

Washing of photovoltaic panels
Why is regular washing of photovoltaic panels essential?
Photovoltaic panels are an investment that can reduce electricity bills and contribute to environmental protection. However, in order for the installation to operate at maximum efficiency, regular maintenance is necessary, including washing the photovoltaic panels. Did you know that even a thin layer of dust, pollen or bird droppings can reduce the efficiency of the panels by 20-25%?
Natural precipitation, such as rain, can remove some of the light dirt, but will not deal with more stubborn deposits, such as soot or greasy stains. Lack of proper care for the panels can lead to the formation of so-called hot-spots - places where dirt causes the modules to overheat, which can result in permanent damage.
That's why it's worth taking care of regular cleaning of the installation, preferably with the help of professionals. At Mansser we specialize in comprehensive and safe cleaning of photovoltaic panels throughout Poland. Thanks to the use of demineralized water and modern equipment, we ensure not only excellent visual effect, but also maximum efficiency of your installation.
Invest in the cleanliness of your panels today and enjoy the benefits of optimal performance!

Can photovoltaic panels be washed by themselves?
Technically, it is possible, but is it worth the risk? Without experience and the right equipment, cleaning on your own can be time-consuming and ineffective. What's more, the cost of repairing damage caused by improper washing far exceeds the price of a professional service.
Advantages of professional cleaning
- Safety: Mansser professionals have the right equipment and training to minimize the risk of accidents.
- Efficiency: With specialized tools and demineralized water, we remove even the toughest dirt.
- Save time and effort: by outsourcing your cleaning to Mansser, you can focus on your daily chores while we take care of the performance of your plant.

Seasonal cleaning of photovoltaic panels - the key to efficiency
Regular seasonal cleaning of PV panels is a simple way to keep them operating at maximum efficiency throughout the year. PV panels are exposed to different types of contaminants depending on the season - from pollen in spring, to dust and rain in summer, to leaves in autumn and snow in winter. Therefore, properly planned PV panel cleaning is not only an investment in cleanliness, but also in the efficiency of your installation.
When is the best time to wash photovoltaic panels?
- Early spring - removal of pollen, dust and residual dirt after winter prepares the panels for the busy energy production season.
