When should solar panels be cleaned?

Many people who depend on this type of energy wonder how to clean solar panels and when is the right time.

The first thing we should do is check the level of dirt on the solar panels to see if they need cleaning. To do this, you can physically inspect them to see if they have dust, bird droppings or other types of dirt, such as haze, and dust that has stained so many buildings, streets or solar panels in recent months.

Another way is to detect if there are losses of 50% over the normal production of the solar panel. This will indicate that the solar panels have to be cleaned so that they are capable of producing energy to the maximum of their capacity.

As for the frequency, we recommend it to clean solar panels between 3 or 4 times a year. However, in winter they do not need to be cleaned as often because the rain contributes to their cleaning. But, we remind you to avoid cleaning on rainy, snowy or windy days to avoid falls and physical damage.

Of course, during the summer they may need more because it rains less, but I recommended it to do it during the first or last hours of the day so that the temperature is lower.

If we clean in the middle of the day, we run a greater risk of getting hurt by burns if we touch the high temperatures of the panel and, furthermore, if we pour water when the plate is hot, a thermal shock occurs that can result in deterioration of the photovoltaic modules.

How to properly clean solar panels?

Materials you will need

  • Bucket of warm water with a small drop of soap, preventing it from generating foam so that no traces of soap remain on the solar panel when it dries.
  • Use a cotton cloth or polyester brush with thick teeth and only wet with water and a little soap, so that the plate does not suffer any scratches or damage.
  • If the panel that needs cleaning is inaccessible, you can use a pole and attach a brush, sponge or cloth to reach more height.
  • If you live in an area where there is a lot of vehicle or plane traffic, it is recommended to use isopropyl alcohol to remove the remains of oily stains.

And remember, abrasive soaps or liquids along with non-corresponding cleaning tools should not be used to clean solar panels as they could damage and deteriorate the surface.
