Different types of dirt get on the underside of the solar panel. So we can carry out the process ourselves to clean such impurities.

The roof under the solar panel deteriorates due to bird droppings, tree leaves, dust, etc., so it must be cleaned periodically.

Use a broom or soft-bristle brush with a light detergent and water to clean it yourself.

Ensure the cleaning solution is completely removed by giving the cleansed area a vigorous water rinse.

Before turning the solar panel system back on, give the roof time to dry out completely.

By cleaning under the panels, you minimize the risk of corrosion or Damage, ensuring they operate efficiently for years.


Can I clean under the solar panels while they are producing electricity?

No, cleaning under solar panels while they generate electricity is not advised. Before cleaning or maintaining the solar panel system, turn it off to minimize electric shock or Damage.

Can I clean under the solar panels by spraying water with a pressure washer?

Yes, you can clean the region beneath the solar panels with a pressure washer on a low setting. Avoid using too much water pressure, though, since this could harm the panels or their connections.

How often should I clean under my solar panels?

Clean under your solar panels twice a year or when energy production drops significantly. Location, weather, and environment affect cleaning frequency.

Can I clean under solar panels without professional help?

Yes, homeowners can clean underneath solar panels. However, it’s advised to use a professional solar panel maintenance service if you are uncomfortable working at heights or around electrical components.

Are there any alternative methods for cleaning under solar panels?
