Cleaning Solar Panels

Updated: Jun 30, 2023



When investing in solar panels, it’s important to maintain their cleanliness to ensure that they operate to the best of their ability. Keeping solar panels clean is an easy and low-cost way to ensure maximum efficiency. In this blog, we’ll go over the basics of how to keep your solar panels clean on a regular basis.

The first step towards solar panel cleaning is to recognize when maintenance is needed. During the summer, rainfall should be enough to keep your panels clean. In the case of mild dust storms or accumulation of small particles such as bird droppings or leaves, regular cleaning may be necessary. However, it is advised not to clean solar panels too frequently as this can impact their efficiency. Cleaning them every few months is generally sufficient.


Once you’ve determined that your panels need some form of cleaning, the best way to go about it is to hire a local solar panel cleaning company. Keep in mind, you do not want to use mild solutions like dish soap or detergents (water works well). Installers may also recommend specialized solar panel cleaners in the area. Using your garden hose puts the dirt that is carried in your water right back onto your solar panels, causing more dirt debris residue to sit after. It is recommended that you find a solar panel cleaning company to assist.

It is also important to note that panels can be damaged from too much scrubbing or using harsh materials as well. Therefore, it’s best to avoid abrasive sponges, hard brushes, or chemical cleaners as these can create scratches or discolor the panels.


Finally, it’s important to note that the best way to keep your solar panels clean is to regularly inspect them. This includes checking for any signs of dirt or buildup of debris and, if necessary, taking action to clean the panels. By keeping your solar panels clean, it will help to maintain efficiency and lifespan of the system.
