EVERY RAY COUNTS ON A CLEAN SOLAR PANEL

UC San Diego researchers found that solar panels left unwashed through a 145-day summer dry spell lost about 7.4 percent of their efficiency, and bird droppings or flat, low-tilt arrays can lose more. Aloha Clean SD provides solar panel cleaning in San Diego, CA, and La Mesa, CA, removing dust, pollen, salt film, and droppings from rooftop arrays. With most local rain arriving between November and March, panels here often go months without any natural rinse at all.

This work follows the solar industry's preferred approach: a pure water system that uses no chemicals, leaves no residue, and dries to a spot-free finish. Harsh cleaners and rough tools can scratch glass or put a manufacturer warranty at risk, so we keep both off your roof entirely. With 10+ years of exterior cleaning behind us, we work carefully around racking, wiring, and roofing. Request a free estimate through our contact page to schedule your panels.

PURE WATER, NO CHEMICALS, NOTHING LEFT BEHIND

Deionized water has had its dissolved minerals stripped out, so it lifts grime and evaporates without leaving the chalky spots tap water would. We pair it with soft brushes that are gentle on glass and frames, and we point out anything unusual we notice along the way, like cracked glass or debris tucked beneath the array.

On service day, switch your system off before we start, a basic safety step for our crew and your equipment. Let us know about delicate components or trouble spots, and make sure we have clear access from the ground and to the roof. Visit our contact page for a free estimate and an open date.

Solar Panels We Carefully Clean

Pure Water Panel Washing

Filtered, deionized water carries away dirt without soap, so nothing is left on the glass to attract fresh dust. Paired with soft brushes, it gently scrubs each module and dries to a clear, spot-free surface that lets sunlight pass straight through.

Bird Dropping Removal

Droppings block light completely wherever they land, and rain alone rarely washes them off. We soften each deposit with pure water before lifting it away, avoiding the scraping that can leave fine scratches or damage the coating on the panel glass.

Dust and Pollen Removal

Months of dry weather let fine dust, pollen, and ash settle into a dull layer that quietly trims your output. A thorough rinse and gentle brushing clears that film from every panel, bringing the glass back to its original, light-hungry clarity.

Coastal Salt Film Removal

Marine air leaves a sticky salt residue that traps dust and hazes the glass over time. Our pure water process dissolves that film without chemicals, which also keeps salt and cleaning products from running off onto your roof, gutters, and landscaping below.

Panel Edge and Frame Cleaning

Grime tends to collect along the lower edge of each panel, where runoff slows and dirt dries in a band. We give frames and edges focused attention and clear leaves or debris lodged in the gaps between modules.

Seasonal Solar Panel Cleaning

Timing a cleaning for late spring, after the pollen settles and before the long, sunny months, puts your panels in top shape when production matters most. Some arrays benefit from a second cleaning in fall, ahead of shorter days.

Why Choose Us for Solar Panel Cleaning

Protection for Your Warranty

Many panel makers spell out approved cleaning methods and warn against harsh chemicals, abrasive pads, and high-pressure spray. Our pure water process stays within that kind of guidance, so you keep your panels clean without putting valuable coverage at risk.

More Power From Every Sunny Day

Clean glass lets more light reach the cells, so your system produces closer to what it was designed to deliver. Over a long dry season, recovering even a few percent adds real value to the investment already sitting on your roof.

Chemical-Free Around Your Home

Nothing we use leaves soap, solvents, or residue behind. That matters for your roof, your gutters, and the plants below, where runoff lands, and it matters for children and pets who spend time in the yard after we leave.

A Finish That Stays Spot-Free

Tap water dries into mineral spots that begin gathering dust almost immediately. Because deionized water holds no dissolved solids, the glass dries clear and stays cleaner longer, stretching the time before your panels need attention again and keeping your output steadier.

Respect for Delicate Equipment

Wiring, connectors, and racking sit inches from the glass we clean. We work with soft tools and steady hands around every component, avoiding the pressure and scraping that can loosen hardware or crack tempered glass on older modules.

Safety Built Into Every Visit

Each job starts with confirming the system is switched off and the access points are clear. That routine protects your equipment and our crew, and it keeps the visit calm and predictable from arrival to the final rinse.

Frequently Asked Questions

  • How often should solar panels be cleaned?

    Once or twice a year works for most homes in dry, dusty climates. Panels near the coast, under trees, beside roads, or frequented by birds may need more frequent cleaning, especially if your monitoring app shows a steady dip in production.

  • Does rain clean solar panels well enough on its own?

    Rain helps with loose dust but rarely removes bird droppings, sticky pollen, or salt film. Light showers can even leave muddy streaks as dust mixes with water, so a proper cleaning still pays off after a long dry stretch.

  • Can I clean my solar panels with a garden hose?

    A hose can rinse loose dust, but hard tap water dries into mineral spots that collect dirt quickly. Climbing onto a roof also carries real risk, which is why many owners leave rooftop arrays to a trained crew.

  • Will cleaning my solar panels void the warranty?

    Aloha Clean SD cleans solar panels in San Diego, CA using pure water and soft brushes, with no harsh chemicals that can void warranties. With 10+ years in exterior cleaning, we know how to protect both your glass and your coverage.

  • Why is deionized water used to clean solar panels?

    Deionized water contains no dissolved minerals, which is why Aloha Clean SD uses it on San Diego, CA, arrays. It pulls dirt away as it rinses and dries without spots, leaving no residue that would attract fresh dust or block sunlight.

  • What time of day is best for cleaning solar panels?

    Early morning or late afternoon is best, while the glass is still cool to the touch. Spraying water onto sun-baked panels can dry too fast and streak, and a sudden temperature change on hot glass is worth avoiding entirely.

  • How can I tell if my solar panels need cleaning?

    Watch your system's production data for a gradual decline on clear, sunny days, and look for visible dust, droppings, or leaves on the glass. If output drops without an obvious weather reason, dirty panels are a likely cause.

  • Should my solar system be turned off before cleaning?

    Yes, switching the system off before cleaning is a sensible safety precaution. It protects the people working on the array and the equipment itself, and your installer's manual usually explains the correct shutdown steps for your specific inverter model.
