Solar Panel Cleaning in Western New York

Solar Panel Cleaning FAQs

Can solar panels be pressure washed?

We do not apply high pressure directly to solar panels. WNY Pressure Wash uses controlled water flow, purified water and soft water-fed brushes to clean panel surfaces without unnecessary pressure around the glass, frames, seals and electrical components.

What is a water-fed solar panel brush?

A water-fed brush is a soft brush mounted to an extendable pole with water delivered directly through the cleaning system. It allows technicians to gently agitate and rinse solar panels from a controlled position.

Are water-fed brushes the same as water-fed brooms?

The terms are sometimes used interchangeably. For solar panel cleaning, we use soft professional water-fed brushes designed to provide controlled agitation rather than ordinary household broom bristles.

Do you use purified water?

Yes, purified or deionized water can be used when appropriate for the project. Removing dissolved minerals from the water helps reduce mineral spotting as the panel surface dries.

Do you use soap on solar panels?

Routine solar panel cleaning can often be completed using purified water and gentle brush agitation. If additional treatment is necessary, the cleaning method is selected according to the contamination and panel condition.

Can you remove bird droppings from solar panels?

Most bird droppings can be removed through controlled soaking and gentle agitation. Long-standing deposits may require additional passes, and permanent etching or surface damage may not be reversible through cleaning.

Can you remove lichen from solar panels?

Some organic growth may be removable through careful soaking and agitation. Heavy lichen can adhere strongly to the panel surface. We will not aggressively scrape or damage the glass simply to force removal.

Do you clean solar panels from the ground?

Whenever practical, yes. Extended water-fed poles allow many roof-mounted and ground-mounted solar systems to be cleaned from the ground or another stable access point.

Will you walk on my roof?

Roof access depends on roof type, pitch, height, weather and overall safety conditions. Whenever possible, we use water-fed equipment from safer access points.

WNY Pressure Wash does not walk on metal roofs.

Do you clean ground-mounted solar panels?

Yes. We clean residential, agricultural and commercial ground-mounted solar arrays when they can be safely accessed.

Do you clean commercial solar systems?

Yes. We clean solar panels at offices, warehouses, apartment properties, industrial facilities, retail properties, farms and other commercial locations throughout Western New York.

How often should solar panels be cleaned?

Cleaning frequency depends on the surrounding environment. Systems near trees, farms, birds, gravel roads or heavy pollen may require cleaning more frequently than panels in cleaner environments.

Does rain clean solar panels?

Rain may remove loose dust but often leaves behind bird droppings, pollen, organic residue and dirt that has adhered to the panel surface. Professional cleaning adds gentle agitation to remove that buildup.

Will cleaning increase solar production?

Removing contamination may improve the amount of sunlight reaching the panel surface, but we do not guarantee a specific increase in energy production. Solar output is affected by many factors beyond cleanliness.

Do you repair solar panels?

No. WNY Pressure Wash provides exterior cleaning services. Electrical diagnostics, solar panel repairs, wiring repairs and system modifications should be completed by a qualified solar contractor.

Can you clean underneath the panels?

Standard solar panel cleaning focuses on the accessible glass surface. Bird nests, animal guards, wiring work, panel removal and extensive cleaning beneath the system require separate evaluation and may need another qualified contractor.
