Dust, bird droppings, and debris accumulation can reduce solar output by 10–30%. In Southwest Riverside County's dry, dusty climate, regular cleaning isn't optional — it's part of owning a solar system.

951.696.9669The Inland Empire's dry climate, Santa Ana winds, and agricultural dust create some of the worst soiling conditions for solar panels in Southern California. Panels that looked clean last spring may have accumulated enough debris to reduce output by 15–25% by summer — right when you need peak production for air conditioning load.
ElectriCare's professional cleaning removes all soiling using deionized, spot-free water and soft brushes designed for solar panel surfaces — no harsh chemicals, no abrasives that damage coatings, and no amateur pressure washing that voids warranties. We also inspect panels for damage during cleaning, so you get a service call and a condition report in one visit.
A cleaning that's worth scheduling — not just a hosing down.
Tell us your panel count, roof type, and location. We'll confirm pricing and schedule a date.
Before cleaning, we do a quick visual assessment — cracked panels, loose racking, bird nesting — so nothing is missed.
Deionized water and soft brush technique across every panel surface. Bird dropping removal with appropriate treatment for stubborn buildup.
Where monitoring is available, we note pre and post-cleaning production values so you can see the tangible difference.
We're not a window washing company that also does solar. We're a solar service company — and cleaning is part of how we look after the systems we service.
Deionized water systems eliminate mineral deposits. Soft-bristle brushes won't abrade the anti-reflective coating on your panels.
A licensed technician on your roof means damage, loose connections, and pest issues get caught — not just the dirt.
Set up a quarterly or bi-annual cleaning schedule and we'll reach out when it's time. No reminders needed on your end.
In Southern California, cleaning typically recovers 10–25% of lost production. That's real money, especially in summer when rates are highest.

For most homes in the Temecula/Murrieta area, twice per year is the standard — once before summer peak season (April/May) and once in the fall. If you're near agricultural land or areas with high Santa Ana wind activity, quarterly cleaning may be warranted. Bird activity is the biggest wildcard — a single heavily soiled panel can reduce an Enphase string's entire output.
Rain provides some rinsing but leaves mineral deposits and streaks as it dries — particularly in Southwest Riverside County where water is hard. Rain also doesn't address bird droppings, which bake onto panel surfaces in the heat. Studies consistently show that rainfall is an inadequate substitute for professional cleaning in low-rainfall, high-dust environments like Southern California's Inland Empire.
Hosing panels with tap water can leave mineral spots that reduce production and are difficult to remove. Pressure washing at close range can damage panel surfaces and void manufacturer warranties. Walking on or around panels without proper equipment is also a safety risk. Professional cleaning is inexpensive relative to the production recovery and risk mitigation it provides.
Studies from NREL and SunPower indicate dust soiling in California's dry inland regions can reduce output by 15–25% annually. Bird droppings create localized shading — a single dropping on one cell can affect the entire string's output in systems without panel-level optimization. After a professional cleaning, many customers see immediate production improvements in their monitoring data.
Yes. We can set up a bi-annual or quarterly cleaning schedule and reach out when it's time. Recurring customers get priority scheduling and consistent technicians familiar with their system and roof. This is the most cost-effective way to maintain peak production year-round.
