Why Solar Panels Get Dirty in the Bay Area

Dust and particulates from Bay Area traffic and construction
Bird droppings — cause hot spots that permanently damage cells
Pollen — especially heavy in spring months
Coastal salt air — accelerates buildup along Peninsula and East Bay
Wildfire smoke and ash residue — significant output reduction
Fog residue and mineral deposits from condensation
Tree sap, leaves, and organic debris

How Often Should You Clean Solar Panels?

Residential (Bay Area): 2–4 times per year recommended. More frequently in wildfire season or if near busy roads, farms, or large trees.

Commercial: Quarterly minimum. Monthly for high-output systems where ROI on cleaning is highest. We can monitor and schedule automatically.

After wildfire events: Immediate cleaning recommended — ash and smoke residue is highly corrosive and dramatically reduces output.

What Dirty Panels Cost You

A typical 10kW residential system generating 14,600 kWh/year at $0.35/kWh (Bay Area average) produces $5,110/year in energy value.

At 20% degradation from dirt: loss of $1,022/year.

Cost of 4 cleanings/year: Typically $150–$400 depending on panel count.
Net benefit: Hundreds to thousands of dollars in recovered energy production annually.
