How to Clean and Care for Your Solar Panels

If you’ve recently acquired solar panels or are interested in potentially adding them to your home or business, you may wonder about the care and upkeep of them.


The truth is, there is very little maintenance needed to clean and care for your panels. That’s just one more perk to owning solar panels! Solar panels are generally maintenance-free.


Even if you leave your panels without any cleaning, the efficiency rating of our panels is still so high (with dirt and debris) that you may not even notice a difference.


However, if simple rainstorms don’t do the trick -- and you begin to see a sticky film still left behind after the rain -- you may need to rethink cleaning. Many times panels become dirty through:

  • Pollen
  • Dust
  • Bird droppings
  • Leaves
  • Ash 


And while the coastal regions see rain more regularly, many parts of California don’t see rain as often as they like. Over time, dust builds up to the point that even consistent rain -- or a heavy downpour -- has trouble completely eradicating the dust.


While cleaning your panels doesn’t need to be expensive, you need to be patient, thorough, and careful. Below are some simple tips you can use to keep your panels in tip-top shape.


Normal buildup: If your panels aren’t too high up on your roof, then try spraying them off with your garden hose. Sometimes, all the panels need is a little water to wash over them and free them from dust and debris. Use a low-pressure nozzle, nothing that can damage the panels and scratch them. Do not use a pressure washer as that may void the warranty. 


Medium-to-high buildup: You will need a bucket of soapy water, a soft sponge, and a squeegee (if panels are at a distance from you, you may use a long pole to reach your panels for the scrubber and squeegee). 


  1. Fill the bucket with water and a gentle soap
  2. Rinse panels with the hose to clear away excess debris
  3. Wash panels gently with the sponge
  4. Rinse panels with hose water again
  5. Squeegee panels dry


Of course, there is another option: if you don’t want to wash them yourselves, the next best thing to do is hire out this cleaning service. Why do it if you don’t have to?


Cleaning your panels, if they need to be cleaned, only has to be done once a year at most. It’s a simple but effective way to keep your panels in their optimal condition, all while giving you the efficiency they are rated at.

Bright Planet consulting does an awesome job from start to finish. Paul Chojnacky did magic not once but twice - yes 2 homes we had owned - he consulted and worked with us. He gets involved from the beginning to the end until we were satisfied. First - we wanted to go green and at the same time we wanted to reduce our electricity bill. In 2015 - He got us a system designed, installed, configured and not only we went green energy, our bills saved over 60% of electricity bills. I had him install a 240V connector in garage and install the Electric car charger. It was a great system and we all enjoyed green energy. Not knowing much of Solar panels we went first time on a lease basis which has 20year free maintenance. Mostly to cover $0 cost maintenance. In May of this year he helped us transfer our lease to the buyer when we sold this home. Basically he went all his way to help us and have a smooth transition. Second time in June/July 2018 - when we purchased a new home, we wanted to go green again. This time we purchased the Solar panels and also have Tesla Wall charger installed. We purchased as we had experience for the last 3 years and took his recommendations. The purchase comes with 20 year worry free warranty. Paul is great and so are his staff members who communicated with me during the initial phase, design, installation and configuration. His staff kept me updated even though I was out of country, but work at home progressed. They do all the work for you from getting inspections, design, permits, approvals from City and PG&E and follow up until we were satisfied. Our system even though producing electricity it was not showing the production on the app or website. He diligently worked with the Solar panel company got it sorted in short while. I highly recommend using Bright Planet Consulting for all your Solar needs and they do an amazing job from start to finish. His staff does excellent work and update the progress. Thanks Paul and team for wonderful work.
