Solar panel cleaning: everything you need to know to improve efficiency

We have already mentioned that one of the fundamental parts of a good maintenance of any photovoltaic panel installation is the correct cleaning of the equipment.

It should be remembered that any solar panel installation is highly exposed to all kinds of climatic phenomena, so a proper cleaning, as long as it is carried out by a specialized professional, will undoubtedly help to prolong the useful life of the installation and, consequently, maximise the levels of energy efficiency.

Dust, environmental dirt, pollution or other elements such as leaves, branches, etc. are usually removed thanks to the natural action of rainfall. However, this does not always happen, especially for installations located in dry or arid areas.

From RDS we want to share some tips that will keep your solar panels as the first day.

Aspects to take into account for a correct cleaning of solar panels

There are many users who try to clean solar panels by themselves, however, from RDS we always recommend that a professional technician performs this task.

Below, we review the essential aspects to take into account for cleaning solar panels correctly:

• Do not use chemicals that can damage photovoltaic cells and modules.
• Maintain safety at all times. Do not climb onto the roof where the installation is located without the appropiate equipment.
• Do not clean the solar panels during the hottest hours of the day to avoid breakage due to the temperature contrast.

If we talk about tools for cleaning a photovoltaic installation, we can see that there is a wide variety. Here are some tips for effective cleaning:

• Use a broom or brush carefully to remove debris that has been placed on the solar panel.
• Try to avoid using pressurized water systems that may damage the installation.
• Try to avoid thermal contrast by using lukewarm water if we clean the solar panels during the hottest hours of the day.
• Always try to use sponges that do not scratch the surface of the modules.
