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, pollen, and debris can cut 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 clear and efficient all year.

Here are seven tips to help you clean smarter and safer, straight from the solar cleaning experts at Neon Clean Ventura.

1. Don’t Rely on Rain

It’s a common myth: “Rain will clean my solar panels.” The truth? Not really. Think about your car windshield after a light rain—it’s not exactly spotless. Rainwater leaves behind mineral deposits and doesn’t remove stuck-on grime like bird droppings or tree sap.

Want a real clean? Schedule a service with a trusted janitorial company in Ventura County like Neon Clean Ventura.

2. Use the Right Tools

Skip the power washer and the harsh brushes—those can scratch or crack your panels. Instead, use a soft brush, a water-fed pole, or even a microfiber cloth if you can safely reach. For best results, clean with deionized water—it dries spot-free and doesn’t leave mineral stains.

3. Clean Early or Late in the Day

Cleaning solar panels at midday isn’t just sweaty—it’s risky. Hot glass cools quickly when water hits it, which can cause cracking. Instead, clean in the morning or evening when your panels are cool to the touch.

Pro tip: We schedule our solar panel cleaning services in Ojai and Thousand Oaks during optimal hours to protect your equipment.

4. Safety First—Always

Most solar panels are on roofs. If you’re not used to working at heights—or don’t have proper safety gear—don’t risk it. Cleaning isn’t worth a trip to the ER.

Leave the heights to us. As a professional cleaning service in Ventura County, safety is built into every job we do.

5. Set a Schedule

Solar panel cleaning isn’t a once-and-done chore. Depending on where you live, you should clean your panels every 3 to 6 months. In areas like Ojai and Thousand Oaks, dust and pollen build up quickly.

6. Keep an Eye on Performance

Many solar systems have monitoring apps. If you notice a dip in your production, especially during sunny months, your panels might be dirty. A quick clean can often restore lost output.

If your solar isn’t producing like it used to, call Neon Clean Ventura to get it back on track.

7. Hire Local Experts

DIY is great—but when it comes to fragile equipment and rooftops, hiring a local pro saves time and headaches. Plus, we know exactly what kind of dirt and weather impact panels in Ojai, Thousand Oaks, and nearby areas.
