Do Commercial Solar Panels Need to Be Cleaned?

Yes, and more often than residential panels, because commercial arrays sit closer to the grime that matters. Industrial dust, diesel particulates, loading dock traffic and flat commercial roof pitches all help soiling bake on rather than wash off, and rain mostly rearranges it.

As a rough guide, industry estimates put soiling losses anywhere from 5 to 25 percent, so a 500-panel array quietly losing even 10 percent of its output is giving away thousands of dollars of generation a year. The array was a capital investment with a payback calculation attached, and dirty panels stretch that payback for no good reason.

and window cleaning into the same schedule, one induction, one invoice

How Often Should Commercial Arrays Be Cleaned?

Sites in Perth's high-dust industrial zones, Malaga, Wangara, Welshpool, Kewdale, Balcatta and Canning Vale among them, typically justify quarterly cleaning, because the dust load between cleans is simply higher. Standard commercial premises, offices in Osborne Park or Belmont, schools, showrooms and the CBD fringe, usually do well on a biannual cycle.

We'll recommend a frequency honestly based on your site and adjust it once we've seen how your array actually weathers, and late winter is the smart booking window either way, clean panels entering Perth's high-yield spring and summer earn their keep fastest.

What Commercial Solar Cleaning Costs

Commercial arrays are quoted per site, because panel count, roof access and induction requirements genuinely change the number. As anchors, domestic-scale systems run $7 to $10 per panel, volume rates apply beyond 100 panels, and full ranges for every service are on our pricing page. The quote is free, and the price you're given is the price you pay.

 Trustindex verifies that the original source of the review is Google. Ellis and his team at Coates Window Cleaning did a brilliant job. Ellis got back to me straight away when I first reached out, and was really clear and helpful the whole way through. On the day, they took real care with everything, even the stained glass window came up brilliantly. The windows are looking fantastic and I couldn't be happier. Five stars, easily.
