Solar Panel Cleaning

Keep your system performing at its best through Sacramento’s dust and pollen.

Keeping your panels clean is one of the simplest ways to protect your investment and keep energy production where it should be. We use safe, non-abrasive methods to remove dirt, dust, pollen, and bird droppings without risking the panel surface or components, especially important in Sacramento’s dry, dusty climate.

Many manufacturer warranties actually require regular maintenance, including cleaning, to stay valid, so a routine cleaning does double duty: protecting your output today and your coverage down the road.

What’s Included

• Dry removal of loose debris before any water touches the panels
• Gentle washing with soft or deionized water
• Non-abrasive, panel-safe cleaning solution for stubborn grime
• Careful rinsing and drying to prevent water spots
• A visual inspection for damage or loose connections during every visit

What We Don’t Do

• No pressure washing
• No abrasive cleaners or tools
• No standing or leaning on the panels

How Often Should You Clean?

Most systems benefit from a cleaning once or twice a year, more often if you’re near construction, busy roads, or trees that drop pollen or leaves. Many customers schedule one cleaning at the end of winter and another at the end of summer or early fall, to clear out both rainy-season grime and dry-season dust. A noticeable layer of buildup, or a drop in output on a sunny day if you monitor your system, is usually the clearest sign it’s time.

Why It’s Worth It

Left unaddressed, dirt and debris buildup can cut output anywhere from a few percent to over 20 to 30% in heavily soiled conditions.

• Restores energy output lost to buildup
• Faster return on your solar investment through better production
• Helps prevent hot spots that shorten panel lifespan
• Keeps you compliant with manufacturer warranty terms that require upkeep
• Catches early signs of damage or loose wiring before they become repairs

Frequently Asked Questions

Will skipping cleaning affect my warranty?

It can. Some manufacturer warranties require regular maintenance, including cleaning, to remain valid, so neglecting it isn’t just a performance issue, it can be a coverage issue too.

Can I clean the panels myself?

You can, but pressure washing, abrasive tools, and standing or leaning on panels can all damage them or void your warranty, which is exactly what our process is built to avoid.

Does rain keep my panels clean enough on its own?

Rain washes away some loose debris, but it won’t remove everything, and mineral deposits from the rainwater itself can still build up over time. It reduces how often you need a professional cleaning, but it doesn’t replace one entirely.

Does a cleaning visit include an inspection?

Yes. Every cleaning includes a visual check for damage or loose connections, so small issues get caught while we’re already there.

How can I tell when my solar panels need cleaning?

Visible dust, pollen, bird droppings, or other buildup are clear signs, but an unexplained drop in energy production can also indicate that the panels need attention. Checking your monitoring data regularly can help reveal gradual losses that may not be obvious from the ground.
