Solar panel cleaning services in the East Valley

Olsen Brothers offers solar panel cleaning in the East Valley for rooftop arrays across Mesa, Gilbert, Chandler, and nearby communities — using de-ionized water and soft brushes safe for photovoltaic glass.

What is pure water solar panel cleaning?

Pure water or water-fed solar panel cleaning techniques are an alternative to traditional cleaning methods. Pure water solar cleaners utilize telescoping poles to reach difficult to access areas of panels and limit ladder use. The poles are fitted with a brush to agitate and remove surface grime and impurities. Pure water is delivered through the pole to the brush head through a narrow hose. The pure water washes away surface dirt and dries spot free, eliminating the need to squeegee.

For a deeper look at desert dust, production, and how we work on arrays, see our article on solar panel cleaning in Arizona.

Why use pure water for solar panels?

Cleaning solar panels on a regular basis will increase the efficiency of the panels. Dirty solar panels are not as efficient at producing power as clean panels. So why hire Olsen Brothers to clean the panels? Unlike glass, photovoltaic solar panels are a complex and fragile array of cells. In addition to the many benefits enjoyed by pure water window cleaners, pure water solar panel cleaners have several distinct advantages over cleaners utilizing other methods. Chemicals used to clean solar panels can actually cause damage and deteriorate the surface of the panels. Chemicals may also leave residues that attract and trap dust and pollutants. Pure water has none of these drawbacks and can not harm the environment. Pure water solar panel cleaners can also reduce their exposure to the hazard inherent in cleaning at height. Telescoping water fed poles allow operators to limit time on ladders and movement on rooftops.

Equipment we use on your array

Cleaning solar panels correctly requires a water-fed pole, specialized brush, and de-ionized water. First, we agitate the panels with the brush and pure water… then we rinse the entire panel with the pure, de-ionized water which will leave you with a spot-free surface and maximum efficiency from your panel system.

FAQ

Frequently asked questions

What areas do you serve in Arizona?

We proudly serve Mesa, Gilbert, Chandler, Queen Creek, San Tan Valley, Apache Junction, and Tempe. Arizona’s dust and monsoon seasons are hard on glass, screens and solar panels, so our routes are designed for fast scheduling across the East Valley. If you’re in one of these cities, we can clean interior & exterior windows, detail frames and sills, and add screen cleaning or hard-water removal as needed. Not sure if you’re in our area? Call (480) 626-8649 or request a quick estimate—we’ll confirm availability and recommend the best plan for your home or business.

How often should I clean my windows?

Because of dust storms, wind and hard water, Arizona homes typically schedule window cleaning every 3–4 months. After major dust events or monsoon rains, an extra visit keeps glass looking its best. Businesses usually choose monthly service for a spotless entry. Each cleaning includes streak-free glass (pure water or squeegee), wiped frames/sills, and optional screen cleaning and track detailing. Want a simple plan? Ask about our weekly route and bundle solar panel cleaning or gutter cleaning to save a trip.

How much does residential window cleaning cost?

Pricing is based on square footage, pane count, size, access (1st vs 2nd story), and add-ons like screen cleaning, track detailing, or hard-water stain removal. Most East Valley homes fall within a straightforward per-pane range; we’ll confirm totals after a quick count or photos. Every job includes streak-free glass inside & out, wiped frames/sills, and a satisfaction guarantee. For the best value, combine windows with solar panel cleaning or add dryer-vent cleaning during the same visit. Call (480) 626-8649 for a fast, accurate price.

How much does commercial window cleaning cost?

Commercial pricing depends on pane count, frequency and access. Storefronts on weekly or bi-weekly routes enjoy lower per-visit costs, while quarterly schedules fit offices or medical suites. We provide exterior only or interior/exterior options, set-day service, and after-hours availability. Routes cover Mesa, Gilbert, Chandler, Queen Creek, San Tan Valley, Apache Junction and Tempe. Need construction cleanup or hard-water removal on glass panels? We’ll include that in the bid.

Best time of day to clean windows

In Arizona, we avoid direct midday sun because heat can flash-dry solution and leave residue. Morning shade, late afternoon, or pure-water cleaning on the exterior prevents spotting. Inside, we work room-by-room to control light and achieve a streak-free finish. If your sprinklers hit the glass, ask about hard-water removal—fixing the source plus a one-time polish keeps windows clear longer.

How do you get streak-free results?

We combine two proven methods: traditional squeegee detailing for interior glass and de-ionized pure water with a water-fed pole for exterior glass and frames. Pure water has no minerals, so it dries spot-free without chemicals—great for high windows and frames. Inside, we edge-detail, wipe sills/frames, and can clean screens and tracks on request. The result: crystal-clear glass without residue.

How often should exterior windows be cleaned?

Exterior glass collects dust, pollen and sprinkler overspray faster than interiors. Most homes schedule 3–4 cleanings per year for exteriors and 2–3 for interiors. If you have sunscreens, adding screen cleaning keeps airflow and light quality high. For homes near construction or on dirt roads, consider a bi-monthly plan or a quick touch-up after big dust events.

What window cleaning equipment do you use?

Our kits include professional squeegees, microfiber detailing cloths, extension poles, ladders, and a pure-water system for safe exterior cleaning up to high second-story glass. Pure-water rinsing removes dirt without soap residue; inside we hand-detail for perfect edges. We can also restore screens, clean tracks, and remove hard-water stains with pro-grade methods.

Is de-ionized (DI) water good for cleaning windows?

Yes. De-ionized (DI) water is ideal for exterior glass because it contains no dissolved minerals that cause spots. We filter water through resins, then scrub and rinse windows and frames with a water-fed pole. DI water is eco-friendly and safe around landscaping. For stubborn sprinkler stains, we pair cleaning with hard-water removal and can suggest ways to reduce overspray.

Is window cleaning safe? Are you insured?

Safety is built into our process. Our technicians are trained in ladder use, fall-prevention and safe tool handling. We plan every job for access, power lines and landscaping, and we’re covered by $1M liability insurance. For many homes, our pure-water system cleans upper windows from the ground—no ladders needed. Every job is backed by our 100% satisfaction guarantee.
