Cleaning balcony power plants and PV systems - How to keep your modules clean and powerful

Regular cleaning of your solar system is an important factor in ensuring the maximum performance and efficiency of your system. Regardless of whether it is a small balcony power plant or a larger PV system, the cleanliness of the solar modules plays a crucial role in the energy yield. Dust, pollen, leaves, bird droppings and other debris can build up on the panels over time and block sunlight. This can result in a significant loss of performance.

Why is cleaning important?

The surface of the solar modules is crucial for converting sunlight into electrical energy. Any type of pollution, be it dust, pollen or bird droppings, can reduce light absorption and therefore affect the efficiency of the modules. It has been proven that dirty panels can produce up to 20% less energy than clean panels.

How often should you clean?

The frequency of cleaning depends on your location and environmental conditions. More frequent cleaning is required in areas with a lot of dust, pollen or industrial emissions. As a rule of thumb, however, you should clean your solar system at least once a year.

Cleaning tips:

Regular visual inspection: Check your solar modules regularly for dirt. Dirt particles can stick, especially after storms or rain.

  1. Gentle cleaning: Do not use aggressive or abrasive cleaning agents to clean the modules. Water combined with a soft sponge or microfiber cloth is often enough.
  2. Timing of cleaning: The best time for cleaning is in the morning or evening when the sun is not shining directly on the modules. Hot water on hot modules can cause voltage differences.
  3. Consider safety: If your solar system is difficult to access, make sure you stand securely when cleaning and do not pose a danger to yourself or others.
  4. Professional cleaning: In some cases it may make sense to hire a professional cleaning company. They have the right equipment and know how to carry out the cleaning without causing any damage.
  5. Avoid high-pressure cleaners: High-pressure cleaners can damage the sensitive surfaces of solar panels. Therefore, avoid using high-pressure cleaners.
  6. Increased efficiency: Clean modules generate more electricity. Through regular cleaning, you can increase the yield of your solar system and thus make your investment more profitable.


Regular cleaning of your solar system is an easy way to maintain the performance of your system and maximize its yield. Keep your modules clean and benefit from efficient and powerful power generation.
