The ideal cleaning frequency depends on your environment, panel angle, and how much dirt or pollution is in your area- but here are the industry- standard guidelines:

⭐️ Standard Cleaning Frequency

Residential panels

- Every 3 months —> if you live in a dusty area, near farms, construction, or high pollen.

- Monthly —> if you want maximum efficiency year-round (common for high end homes or heavy dust regions)

Commercial/ industrial

- Every 1-3 months —> because efficiency equals revenue, and these systems operate at higher production levels

- Large flat arrays collect dirt faster and often need monthly cleaning for consistent performance.

⭐️ if ANY of these apply, you should clean more often

- Nearby dirt roads or construction

- Low- angle or flat- mounted panels

- Air pollution (industrial or wildfire areas)

- Tree sap or hard water staining

⭐️ Skipping washes can lead to:

- 15-30% efficiency loss

- Permanent hard water etching

- Decreased ROI

- Loss of warranty depending on manufacturer

Yes- cleaning is safe for both Solar panels and your roof, as long as it’s done correctly. Professional cleaning (like what PanelPro Solar Wash would provide) actually protects the panels and roof rather than harming them.

Here’s the breakdown:

✅ Why Cleaning is Safe

1. Solar panels are designed for water exposure and built to withstand:

- Rain

- Snow

- Hail

- Intense heat

- Wind

Gentle pure water (RO/DI) is completely within what they’re engineered for.

2. Proper cleaning uses deionized water + soft brushes

- Soft, non-abrasive brushes

- Pure RO/ DI water

- No chemicals preventing scratching, streaking or residue.

3. Keeps warranties valid

Most manufacturers require periodic cleaning to maintain maximum efficiency. Leaving them dirty for too long can void performance guarantees- not cleaning them.

PanelPro Solar Wash used advanced AI scheduling to keep your Solar panels performing at their absolute best. Our smart system analyzes weather, dust, pollen, and air-quality data to predict exactly when your panels need cleaning- no guessing, no wasted appointments. You get maximum energy output , longer panel lifespan, and a hands-off maintenance experience. With AI watching over your system 24/7, your Solar investment stays protected automatically.

✅ “How much does it cost”

Our pricing is based on the number of panels and the level of service you choose. Pricing per panel depends on size, accessibility and frequency. We offer bundled and subscription plans to help lower the price per cleaning. I’m happy to give you a fast quote once I know how many panels you have and wether the system is on a roof, ground- mounted, or commercial array.

✅ “Do you offer subscriptions.”

Yes we offer monthly or annual subscription plans that lock in discounted pricing and ensure your panels always stay clean. Our subscriptions use AI scheduling, so your system is cleaned exactly when it needs it- not too early, not too late. Most customers choose an annual plan because it balances cost while maximizing energy output

✅”Why subscribe?”

Subscribers save money per cleaning, get priority scheduling, and never have to worry about dirty panels holding back their energy production. It’s hands off and keeps your panels at maximum power all year long.
