Commercial Solar Panel Cleaning Service

Rooftop and ground-mounted arrays sit exposed to dust, pollen, tree sap, salt near the coast and droppings from birds. On low-pitch commercial roofs the rain rarely clears it, so a film builds along the bottom of each panel and shades the cells beneath. That shading drops generation and, over time, can create warm spots on the glass.

A soiled array simply produces less. Cleaning removes the layer that rainwater leaves behind and gets the modules back to doing their job. The effect is worst on shallow-pitch panels, where water pools rather than runs off, and for larger sites the lost output adds up quickly across a billing year.

A specialist typically uses purified water and a soft water-fed brush or pole system, reaching panels from the ground or roof level without harsh chemicals that could mark the glass or void a warranty. The work is planned around access, height and the layout of your roof, and carried out to the relevant safety standards by a qualified provider.

You get an honest assessment first: some arrays need a single visit, others suit a scheduled clean. PPA Funding passes your details to a provider who quotes for the site as it actually is.

It depends on the setting. A site near trees, farmland, a main road or the coast collects grime faster than a clean suburban roof. Many businesses book a clean once or twice a year, and more often where droppings or heavy soiling are visible. A provider can recommend a sensible frequency after looking at your generation figures and location.

Cleaning is usually planned around your working day so the site is not disrupted, and on industrial or multi-tenant roofs it can be timed to suit access. Booking is simple: tell us the array size, roof type and access, and we pass it to a provider to quote.
