EGA Pressure Washing
Solar Panel Cleaning in Northeast Florida
Solar panels lose 15–25% of their output efficiency when coated with pollen, dust, bird droppings, and organic residue — a real problem in Northeast Florida, where spring pollen season can coat exterior surfaces in days and summer afternoon storms deposit particulate from the St. Johns River basin. EGA Pressure Washing cleans solar panels using purified water and soft, non-abrasive tools that lift surface buildup without scratching the anti-reflective coating or stressing the seals around panel edges.
We clean residential and commercial solar arrays in St. Augustine, Jacksonville, Nocatee, Ponte Vedra, Palm Coast, and throughout Northeast Florida.
Florida's solar ROI depends heavily on panel cleanliness. A panel coated with pollen and residue in April — the peak of Northeast Florida's tree pollen season — can test at 15–20% below its rated output. Summer afternoons bring another layer of particulate from localized convective storms. Panels installed on shaded sections of the roof accumulate organic growth faster because the lower surface temperature lets moisture linger.
Our cleaning method uses deionized or reverse-osmosis purified water, which dries without leaving mineral spotting or water streaking. Tap water — even soft water — leaves calcium deposits on the panel surface that can reduce light transmission over time. We use only soft brushes rated for photovoltaic glass, never abrasive pads or high-pressure nozzles that can stress the EVA film inside the laminate.
We inspect mounting hardware and visible wiring during each cleaning and note anything that warrants attention. We don't perform electrical work, but catching a loose mounting clamp or a chafed conduit run early is a useful byproduct of regular cleaning.
For arrays with microinverters, we follow the manufacturer's recommendation to clean in the early morning or late afternoon to avoid thermal stress from sudden water contact on a hot panel surface. Most residential jobs take 1–2 hours. We leave no cleaning residue, detergent, or equipment drag marks on your roof surface.

Solar Panel Cleaning — Frequently Asked Questions
How much efficiency do dirty solar panels lose in Florida?
Studies consistently show 15–25% output reduction when panels are coated with pollen, dust, and organic residue. In Florida, peak pollen season and summer storms can coat panels within days. The efficiency loss translates directly to higher utility bills and slower payback on your solar investment.
How do you clean solar panels without scratching them?
We use purified (deionized or RO) water and soft-bristle brushes rated for photovoltaic glass. No abrasive pads, no harsh detergents, no high-pressure nozzles. Purified water is critical — tap water leaves calcium deposits that reduce light transmission even after the visual surface looks clean.
How often should solar panels be cleaned in Northeast Florida?
Every 6–12 months for most residential installations. Spring cleaning after pollen season is the highest-value service interval. Panels under trees or near bird activity may benefit from cleaning twice a year. We'll recommend a schedule based on your array location and tree canopy during the estimate.
Do you clean panels on steep rooflines?
Yes, we clean panels at any pitch where safe roof access is available. We use appropriate fall protection on steep pitches. If your array is on a section of the roof we can't access safely, we'll tell you clearly rather than attempt the work in an unsafe condition.
Is there a best time of day to clean solar panels?
Early morning or late afternoon is best. Cleaning panels when they're hot from direct midday sun creates thermal stress from the cold water contact, and the water evaporates too quickly to clean effectively. We schedule solar panel jobs during cooler hours for this reason.
