7 Smart Tips to Keep Your Solar Panels Spotless and Efficient

Just like dirty windows block your view, dirty solar panels block your savings. In the Inland Empire, panels get covered in dust, bird droppings, ash, and desert debris that can reduce efficiency by up to 25%. A little routine maintenance—or help from local experts—can make a big difference.

Here are seven practical tips from the pros at Neon Clean IE to help keep your solar panels clean, safe, and performing at their best.

1. Don’t Rely on Rain

Rain in Riverside or San Bernardino might help a little—but it won’t get your panels truly clean. Rainwater leaves mineral spots and doesn’t wash away sticky grime like tree sap or bird waste.

For a real clean, schedule service with a professional janitorial company in the Inland Empire like Neon Clean IE.

2. Use Gentle Tools and Purified Water

Solar panels are durable, but not invincible. Avoid using abrasive scrubbers or pressure washers. Instead, clean with a soft brush, water-fed pole, and deionized water to avoid streaks or mineral deposits.

3. Clean During Cool Parts of the Day

Spraying cold water on hot solar panels—especially under that Inland sun—can lead to thermal shock and cracking. The best times to clean are early morning or late evening, when panels are cool.

We always schedule solar panel cleaning in the Inland Empire at safe, optimal times.

4. Think Safety First

Small business cleaning professionals in Inland Empire.

If your panels are on a steep or high roof, don’t risk climbing up with a hose and brush. Without the right gear and experience, it’s not worth the danger.

Our trained and insured team at Neon Clean IE, a janitorial company in the Inland Empire, is equipped to clean safely and effectively.

5. Keep a Cleaning Schedule

Dust storms, wildfire ash, and heavy pollen seasons can all dirty panels fast in areas like Moreno Valley, Redlands, or Ontario. Aim to clean your panels every 3 to 6 months to maintain optimal energy production.

We offer recurring cleaning plans throughout the IE to make it easy for you to stay consistent.

6. Watch for Performance Drops

Most solar systems include an app or dashboard to monitor output. If you notice a dip—especially during sunny weeks—dirt is often the culprit. A single cleaning could restore your system’s full power.

Seeing a drop? Call Neon Clean IE to get your panels back to peak performance fast.

7. Hire Local Pros Who Know Inland Conditions

From high winds in Rancho Cucamonga to dust and smog in Fontana, the Inland Empire presents unique challenges for solar panels. That’s why working with local experts makes all the difference.
