7 Smart Tips to Keep Your Solar Panels Spotless and Efficient

Just like dirty windows block your view, dirty solar panels block your savings. Dust, bird droppings, smog, and pollen can reduce your solar system’s performance by up to 25%. But with just a little effort—or the help of local pros—your panels can stay clean and efficient all year.

Here are seven smart tips to help you clean better, safer, and more effectively, straight from the solar cleaning experts at Neon Clean LA.

1. Don’t Count on Rain to Do the Job

It’s a myth: “Rain will clean my solar panels.” Not quite. Think about your car windshield after it rains in Los Angeles—not exactly sparkling. Rain leaves behind mineral spots, and doesn’t wash off things like sap or bird droppings.

For real results, trust a reliable janitorial company in Los Angeles like Neon Clean LA to get the job done right.

2. Choose the Right Tools

High-pressure washers and rough scrubbers can actually damage your panels. Instead, go for a soft brush, a water-fed pole, or a microfiber cloth. Even better? Use deionized water, which dries without spots and won’t leave mineral residue.

3. Clean in the Cool Hours

Midday sun heats up your panels. Spray cold water on hot glass and you risk cracking it. That’s why the best time to clean is early morning or late evening, when panels are cooler and safer to work on.

We schedule our solar panel cleaning services across Los Angeles during safe temperature windows to ensure no thermal damage.

4. Safety Above All

If your panels are on a sloped or multi-story roof, think twice before climbing up with a hose and brush. Falls and injuries can happen fast. Always use proper harnesses—or better yet, call a pro.

Stay safe and let the experts handle it. Our team at Neon Clean LA, a trusted janitorial company in Los Angeles, is fully trained and insured.

5. Create a Cleaning Routine

Depending on the environment, solar panels should be cleaned every 3 to 6 months. In areas like Los Angeles where urban dust, pollution, and tree pollen are common, a regular cleaning schedule is key to long-term efficiency.

6. Monitor Your Solar Output

Most systems let you track output via an app or dashboard. If you notice a drop in performance, it’s often due to dirt buildup. A quick clean might be all it takes to restore lost energy.

If your production numbers are down, reach out to Neon Clean LA—we’ll help get things back on track.

7. Hire Local Solar Cleaning Experts

Cleaning your panels the right way requires knowledge, tools, and experience—especially in a big city like Los Angeles. Hiring local professionals means faster service and better results.
