To prevent dirt from accumulating on the panels, when studying the solar installation, the installation company must consider the proximity of trees, roads, and other factors that may harm production. It is necessary to clean the panels at least once a year to ensure their optimal performance. Generally, the rain keeps them clean the rest of the time except in specific cases.

8 Solar panel cleaning tips anyone can do

Cleaning the solar panels is a task with greater importance than it may seem and should be done by following a few simple tips. If you already have a self-consumption installation or you’re thinking about putting solar panels on your house’s roof, surely you have already realized that, with time, a layer is deposited on the surface of the glass of dirt. It is important to know how to clean solar panels. This occurs due to the suspended dust in the environment, which the further south, the more frequent it is. Also, bird droppings, pollen from flowers, tree leaves, and so on… Also, it can significantly reduce the performance of solar panels.

In accumulated dirt situations, such as the one in the previous image, losses of 50% can occur over the expected production of a solar panel. So, as you can see, removing the dirt accumulated on the solar panels is very important. To clean solar panels, you will need three simple tools:

  1. A bucket of water, if it can be warm better, with a drop of soap (very little soap to avoid foam).
  2. A cloth or a polyester brush with thick bristles to avoid scratching the panel glass.
  3. If they are somewhat inaccessible, you can help yourself with a pole and placing the brush at one end.

With only those materials, you are ready to clean, and that your installation of solar panels for self-consumption produces energy at its maximum capacity, which is recommended to do at least 3 or 4 times a year, with each change of season, for example.

  4. Wipe the dirt off the rag or brush and start over.

Don’t use abrasive soaps or liquids as they could damage the surface of the panel. Also, try not to use any cleaning utensil that could scratch the glass of the solar panel.
