What Is the Best Time of Year for Cleaning Solar Panels?

Oct 10, 2020

Solar panels always work best when they’re clean. Dirty buildup prevents sunlight from striking your panels and limits their productivity. Regular maintenance from Energy Saving Pros will ensure that your system operates at peak performance. We offer solar panel cleaning in Sacramento and throughout northern California. Whether it’s removing springtime pollen or urban pollution, cleaning your solar panels will improve their efficiency and make them last longer. 

How Often Do Solar Panels Need Cleaning?

How often you need to clean your solar panels will depend on your location. Surface buildup varies greatly between sites, and it’s not just about geography. Sites that are only a few miles apart can have very different requirements, depending on their proximity to forests and pollinating plants or exposure to pollution. Energy Saving Pros offers maintenance contracts for twice a year or four times a year, according to your needs.

What Is the Best Time of Year for Cleaning Solar Panels?

Trees and plants can create a lot of debris. Cleaning your solar panels after the spring pollen season will help them soak up more summer sunshine. A second cleaning in autumn after the leaves have fallen will help keep them productive during the shorter days of winter.

Spring and fall are also the best times to clean up messes from birds, insects, and animals. Bugs and critters are most active in the spring and summer and least active during the winter. If your solar panels get frequent visits from wildlife, ask us about Critter Guard—it’s the ultimate barrier to pests, birds, and rodents.

Dust, smoke, soot, and pollution can build up during any season. The best time for cleaning solar panels to get rid of soot from forest fires is usually late autumn. Urban air pollution can also affect the output of your solar panels. Depending on the local air quality, your panels may need cleaning several times a year.  

Solar Panel Cleaning in Sacramento

It’s always best to hire a professional for solar panel cleaning. Ordinary detergents leave a residue that blocks sunlight and attracts more dirt. Hard water can also leave mineral deposits that block sunlight. Pros have the tools and expertise required to get the job done right. When you hire Energy Saving Pros for solar panel maintenance, you get a lot more than clean panels. Our maintenance contracts include regular solar panel cleaning with a full 6-point inspection.
