What maintenance does rooftop solar need?

Direct answer

Visual checks from the ground, gutter clearing, and occasional professional cleaning if soiling is heavy. Do not walk a tiled roof or spray a live array unless you are qualified. Inverter fault lights and monitoring drop-offs are the usual early warnings.

The FAQ states the short version. This note is the Australian weather version.

What you can do from the ground

Look for a dark, dirty array after a long dry spell inland, salt film after a coastal blow, or leaves in the gutter before a Brisbane storm or a southern winter. A gutter that overflows under an array is a roofing problem that will be blamed on solar if you let it.

Check the inverter display or the monitoring app. A sudden drop that is not weather is a call to the installer, not a reason to climb. Keep the warranty pack — see warranties.

What you should not do

Do not walk terracotta or concrete tiles. Do not hose a live array from a ladder. Do not open an inverter. Do not “tighten a clamp” after a northerly. That is how people fall and how warranties void.

Animal mesh, if it was in the scope, is there for a reason. Possums in inner Melbourne and birds on a Townsville shed are not theoretical.

When to hire someone

Heavy soiling that rain does not shift. A persistent fault. A suspected leak. A monitoring outage that is not your home internet. Use the company that holds the workmanship warranty when you can. Use a CEC-accredited service pathway, not a random “I do roofs.”

We will not invent a cleaning calendar for Darwin versus Hobart. Wet-season mould and alpine frost are different conversations. The installer who knows the site should say if a clean is worth it.

Weather is local

Inland dust, coastal salt, Brisbane storm gutters, and alpine frost are different. We will not invent a national cleaning calendar. Hire a qualified cleaner if rain does not shift the film. Do not walk tiles. See FAQ, panels, warranties, and installers.

From the ground

Look, clear gutters, hire a professional if soiling or alarms persist. Do not walk tiles or spray a live array. Monitoring drop-offs are the early warning.

Carry this into the quote meeting

Ground checks, gutters, professional cleans, no live-array heroics. Alarms and monitoring drop-offs are the usual early warning.
