FAQ

Solar Panel Cleaning — Common Questions

How much does solar panel cleaning cost?

Most Central Valley companies start around $150–250. Golden Rays starts at a $100 minimum service fee and scales with panel count and roof height. Steep or hard-to-reach roofs are the single biggest factor in the final figure. Our cost calculator gives you an exact price before you call.

How often should solar panels be cleaned?

At least twice a year in the Central Valley, and the timing matters more than the interval. The standard “every six months” advice drifts off the months that count. Weight your cleanings toward summer, when dust is heaviest, energy rates peak and your home draws the most power — that is when dirty panels genuinely cost you money. Commercial sites are better served three to four times a year.

Do you use soap or chemicals on the panels?

Neither. We use a no-soap method with deionized water. Soap leaves a film that attracts dust straight back, so panels get dirty faster after a soapy clean than before it.

Will hard water leave spots on my panels?

No. Our vehicles carry onboard deionized water filtration, so minerals are stripped out on site before the water touches your glass. Panels dry spot-free with no residue that could affect your panel warranty.

How long does a solar panel cleaning take?

Most companies take one to two hours. We typically finish in about half that — the difference is proper ladder safety systems and purpose-built solar cleaning equipment rather than the window-cleaning supplies much of the trade still uses.

Can you clean panels during summer heat?

Yes. Our crews and equipment are set up to work safely in 100°F-plus conditions, and we operate seven days a week. The no-soap method with slightly heated deionized water means we can clean right through the hottest part of the day.

Do I need to be home for the cleaning?

No. We complete the work and send before-and-after photos so you can see the result. Most of our customers are at work while we are on the roof.
