Solar Panel Cleaning Q&A

Do solar panels need to be cleaned?

Yes. Solar panels need to clean at least every 6 months.

Will a good rain clean my panels?

No, after rainwater evaporates, grime accumulates and forms a film of dirt. Which, in turn, reduces the light getting into the solar panels.

Do solar panels lose efficiency when they are dirty?

Yes. Over time, dust, dirt, residue, and most recent ash particles have accumulated and are reducing your solar panel's efficiency output by 25%.

When is the best time to clean my solar panels?

The spring is the best time to wash your solar panels leading up to June's summer solstice, the longest day of the year!

Should I skip washing them in the fall and winter months?

No. Washing your panels during the fall is just as important. Washing off the accumulated filth that settles during the summer months allows the optimal conditions to absorb what little sunlight is available, leading up to winter solstice, the shortest day of the year.

How does "Return on Investment" play into this?

Your solar system design was based on your solar panel's ability to offset your electric consumption. Consequently, neglecting your solar panel's routine cleaning can interfere with your "Return on Investement" time frame.

The Process

We start the cleaning process by connecting your tap water directly to our deionizer tank. Deionization (DI) is the process of removing dissolved impurities, such as iron and calcium from water. A consistent spotless finish!

After the water is filtered, the water is plumbed through our drought friendly rotating extension brush, the P.V. Cyclone 1,000(single head). Your solar panel count and arrangement may require the use of the P.V. Cyclone 2,000(double head brush) in order to achieve a consistent wash.  

The P.V. Cyclones are soft bristles “no-scratch” brushes and are used to clean the surfaces of the solar panels. The long extension bars allows us to reach any difficult arrangements. 

Solar Panel Wash finishes each project on schedule and with the highest level of quality. With a focus on personalized service, competitive rates and customer satisfaction, we’re always striving to meet and exceed expectations.
