Do I Need to Clean My Solar Panels?

Yes—and if you care about performance, savings, and protecting your system, regular professional cleaning isn’t optional—it’s essential.

Solar Panels Don’t Stay Clean

Here in the Imperial Valley, panels get covered fast. Dust, sand, pollen, bird droppings, ash, and grime build up layer by layer—blocking sunlight and reducing your system’s output by as much as 15–30%. That’s lost power, month after month, and higher electric bills for you.

Cleaning = Real Savings

When panels are clean, they work at full capacity. That means lower bills, faster return on investment, and maximum efficiency—especially during peak sun months. In some cases, our customers have seen immediate improvements in performance and production after a single cleaning.

Warranties Require It

Most panel manufacturers require regular, documented cleanings to keep your warranty valid. Skipping this simple step can cost you big later if a panel fails or output drops unexpectedly. Regular maintenance protects not only your system, but your long-term peace of mind.

Rain Won’t Do the Job

Rain leaves behind mineral deposits, water spots, and dust streaks—especially in the dry desert climate. Just like your car windshield, panels need professional cleaning to stay clear and effective. A rinse isn’t enough. It takes the right tools, purified water, and proper technique to get the job done right.

Protect Your Investment

Solar is a long-term investment, and like anything valuable, it needs care. Built-up grime causes panels to run hotter, which adds wear and reduces lifespan over time. With proper cleaning, you can help your system last longer, perform better, and save more.

How Often Should You Clean?

For most homes, we recommend cleaning twice a year—once in the spring and once in the fall. Homes near agriculture, wind-prone areas, or construction zones may benefit from more frequent cleanings. We’ll help you determine the right schedule based on your location and panel condition.

Bottom line:
Your panels are working every day to save you money. Keep them clean, protected, and performing their best—with professional service you can count on.
