Solar panels are generally low-maintenance, but depending on the location, weather conditions, etc., some places may require more maintenance than others.

In this blog, we’ll look at the general expectations of solar panel maintenance, touching on topics such as:

Do Solar Panels Require Any Maintenance?

Yes, solar panels need maintenance. Solar panel maintenance companies will typically recommend no more than two to four visits annually. These visits are for cleaning and inspecting the system. The number of recommended maintenance visits is based on how well your panels are working, placement, regional climate patterns, and if they need to be monitored for any issues.

How Do You Maintenance a Solar Panel?

Solar panel maintenance services will inspect the solar panel installations to determine if any repairs or replacements are needed and the expected amount of electricity being generated. During this time, solar panels are also cleaned to increase efficiency. To maintain solar panels, the solar company will look at the exterior and interior of the system to search for any damage, cracks, or scratches. They’ll also look at the mounting system to ensure it’s secure and remove debris and recommend trimming nearby trees that block sunlight.

How Often Do Solar Panels Need to be Cleaned?

Solar panels typically should be cleaned every six months to a year. It will depend on the area you live in, the amount of dirt pollution, weather conditions, and the angle of your panels. In regions with dirt pollution, you’ll likely see a more frequent build-up of leaves and dust. While it’s recommended that solar panels sit at a slight angle, the exact degree can impact the amount of debris that builds up instead of sliding off.

What Happens if You Don't Clean Your Solar Panels?

Because solar panels sit outdoors, typically on roofs, they’re prone to building up debris due to weather and pollution. Being covered in leaves, dirt, twigs, etc., impacts the amount of sunlight reaching the panels.  It’s essential to wipe down the exterior and remove debris. 

If you don’t clean your solar panels regularly, you’ll see a decrease in the amount of energy output. While you can do this yourself, there are risks, such as climbing onto the roof and accidentally damaging parts of the panels. Panels have many moving parts, and it’s best to hire regular maintenance professionals to provide optimal cleaning.

Do I Need to Turn off Solar Panels to Clean?

Another reason it’s recommended to hire a professional cleaning is that you have to alter the solar panels directly. Turning off solar panels while cleaning minimizes the risk of electrical shock due to using water-based solutions.

When cleaning solar panels, the following steps should be taken:

  • Turn off the inverter
  • Wait for the panels to cool down
  • Use a soft brush or sponge
  • Avoid using too much water at a time
  • Avoid harsh chemicals, use soapy water or small amounts of detergent
  • Rinse thoroughly to remove soap residue

How Long Do Solar Panels Last Without Maintenance?

Without maintenance, solar panels may or may not last as long. Even if they’re correctly installed and in a sun-exposed location, without cleaning and inspections, their efficiency may decrease without cleaning and inspections. A lack of maintenance could put your solar panel system at risk of undetected damage and repairs or cluttered debris. Maintenance is important and should be utilized to ensure you’re receiving a total return on your investment.
