Why Solar Panel Cleaning Matters in the Inland Empire
The Inland Empire has high solar potential — but also high dust, pollen, and wildfire ash accumulation. A single layer of dust can reduce output by 7–15%. After wildfire season? Up to 30%. Professional cleaning directly protects your monthly energy savings.

Solar Panel Cleaning FAQ — Jurupa Valley & Inland Empire
Common questions from solar panel owners in Riverside County.
How often should solar panels be cleaned in Southern California?
In the Inland Empire, we recommend cleaning 2–4 times per year. Dust, pollen, and wildfire ash accumulate quickly in our dry climate, and dirty panels in direct SoCal sun can lose 15–30% efficiency.
Will cleaning my solar panels void the warranty?
No — as long as cleaning is done with approved methods. We use soft-wash techniques and DI water that meet or exceed all major manufacturer recommendations (LG, SunPower, Tesla, etc.).
How much efficiency can I regain from a cleaning?
Depending on how long since the last cleaning, customers typically see a 10–25% improvement in output. We measure before and after so you can see the exact difference.
Do you work on steep or high rooftops?
Yes. Our technicians are trained in rooftop safety and use proper fall protection on all pitches. We're insured for this work specifically.
Can I just rinse my panels with my garden hose?
You can, but tap water in Jurupa Valley and the Inland Empire is high in minerals and will leave white spots as it dries — actually making panels less efficient. DI water rinsing is essential for truly clean results.
