Why You Should Clean Your Solar Panels?

Your need to clean your solar panels will depend on where you live. Some areas have a lot of loose dirt that gets blown around, others can have a pollen count so high that it leaves a yellow film on every outdoor surface. Areas with high rainfall will have the least amount of difficulty with dust, dirt, and pollen, but might develop hard water spots. In cold areas, precipitation might turn into snow or ice that can block the collector.

How to Clean

Solar panels come is a wide variety of types and styles. The most common are the glass-fronted panels that are installed either on roofs or on ground-level frames. Ground-mounted panels are often used for large installations where there simply will not be enough roof space.

They are, in many ways, the easiest to clean and maintain because no ladders or scaffolds are involved. You should, however, check for breaks or leaks around the edges of your panels to avoid getting water on the electrical parts.

Checking the panels to see that they are in proper working order is a good idea for roof installations, as well. But the big issue with a roof is its accessibility. “Roof” can mean all sorts of shapes, materials, and different degrees of access risk.

If you’ve not worked in a rooftop environment before, it is a good idea to study up on safety precautions for working in elevated environments.

Keep in mind that the information provided here is for your information. It is just to give you some ideas about what is possible and to make suggestions. When in doubt, call in the professionals.

Best Solar Panel Cleaning Tools

How to judge the “best” in best solar cleaning tools? It isn’t always the most expensive or the fanciest tool that will work well for you.

  1. Brushes and Poles

One of the main components of your solar panel cleaning tool is the pole. You want a pole that is sturdy but that is light enough to handle from the ground or from a ladder or scaffolding. It needs to either collapse or come apart for storage or for work that is closer to the ground.

The other main component is the cleaning head, which will often be a soft-bristle brush. You want a brush that is sufficiently stiff to brush away loose dirt and to scrub stuck-on bits like the little presents that birds like to leave for you.

  1. Water Pumps

If you are a modern homesteader who is doing back to the land effort, a pressurized well might not be available. In such cases, you can purchase a small water pump from your local hardware that can be battery-driven or run off a small generator.

  1. Water Purification Equipment

Hard water is tough on solar panels. It can cause spotting and create mineral deposits. If you know that your water is too hard to do laundry easily or your soap won’t lather up in the shower, you might want to invest in a water filtering/purification system. You might even be able to make your water purifier part of your passive solar system. If that is not an option, you can purchase a stand-alone water filter/purifier that will clean the excess minerals from your water.

If you are collecting rainwater or if you have soft water in your area, then mineral deposits on your solar collectors won’t be a problem. Just go easy on the cleaner so you don’t develop a soap film.

  1. Ladders

Extra tall roofs and similar situations are sometimes out of reach of even the best solar panel cleaning equipment. In such cases, you will need to use a ladder or even scaffolding to reach your collectors. OSHA provides a safety manual for roof workers, which can apply to home DIY roof projects as well. Remember, clean is good, but keep safe by following the best practices precautions.


By using the best solar panel cleaning equipment you can keep your photovoltaic charging panels in excellent condition. There are a lot of things about solar panels that cannot be easily cured, such as browning with age. But keeping dust and dirt off them will increase their efficiency to an amazing degree.

You don’t need every tool listed on this page; just the one that will work well for you. But this selection will help you select the one that is your “just right” solution for clean solar panels, windows, and other hard-to-reach surfaces.
