How much does solar panel cleaning cost in Mildura?

Mildura Shine Co works to a guide price of $15 per panel. A typical 6.6kW system of around 20 panels is about $300. Minimum job $150, and bundling with a window clean saves the callout. The written quote is fixed before work starts.

Is it worth getting solar panels cleaned?

Published research puts real numbers on soiling: a UNSW study in Applied Energy (2022) found Australian solar farms lose 8-9% of output to dust, and IEA PVPS (2025) reports an average soiling loss of 4-7%. Results on an individual home roof vary with tilt, dust and rainfall, so we do not promise a specific percentage - we show before and after photos instead.

Do you walk on the roof to clean solar panels?

No. Panels are cleaned from the ground with a water-fed pole and soft brush, reaching up to two storeys. Nobody stands on your roof or your array.

Will cleaning void my solar panel warranty?

Deionised pure water and a soft brush is the gentle method panel manufacturers describe in their care guides - no chemicals, no detergents, no high pressure. Harsh chemicals and pressure washers are what put warranties at risk.

The honest numbers

What dirt actually costs - from published research.

Plenty of cleaners quote wild "up to 25%" figures. We'd rather show you what the research actually says and let your before-and-after photos do the talking.

UNSW: 8-9% at Australian solar farms

A UNSW study published in Applied Energy (2022) found Australian solar farms lose 8-9% of output to dust soiling.

IEA PVPS: 4-7% average

The International Energy Agency's PVPS program (2025) reports average soiling losses of 4-7% across monitored systems.

Your roof: we don't guess

Home results vary with panel tilt, local dust, bird traffic and rainfall. So we never promise a percentage for your system. You get clean glass and photos, not inflated claims.

Mildura is dust country

Low rainfall, dry summers, wind-blown topsoil and busy birdlife mean Sunraysia arrays soil faster than coastal ones. Flat-mounted panels cop it worst because rain can't sheet the grime off.

Good questions

What Mildura locals ask about solar cleaning.

How much does it cost to get my solar panels cleaned?

$15 a panel as a guide. A standard 6.6kW system - usually around 20 panels - comes to about $300. Smaller systems fall under the $150 minimum job, so it's worth bundling an exterior window clean into the same visit. The quote is fixed in writing first, and it can only drop on the day, never rise.

Is it actually worth doing, or is that a sales pitch?

Fair question. A UNSW study in Applied Energy (2022) found Australian solar farms lose 8-9% of output to dust. The IEA PVPS program (2025) reports 4-7% average soiling loss. What your roof loses depends on tilt, dust and rain, so we won't promise you a number. In Mildura's dust, panels untouched for a year or two are rarely clean.

Do you walk on the roof?

No. Everything is done from the ground with a water-fed pole and a soft brush that reaches up to two storeys. Walking on arrays risks microcracking panels and damaging your roof - if we can't reach it safely from the ground, we'll tell you straight instead of climbing.

Will cleaning void my panel warranty?

Our method is the one manufacturers describe in their own care guides: pure deionised water and a soft brush, no chemicals, no high pressure. It's harsh detergents, abrasives and pressure washers that put seals and coatings - and warranties - at risk. We don't carry any of those.

Can't the rain just clean them?

Rain helps on steep panels, but Mildura doesn't get much, and what falls often dries leaving dust and mineral film behind - especially on low-tilt arrays. Bird droppings don't rinse off at all, and one dropping can shade a cell hard. That's why we use deionised water: it dries clean with nothing left behind.

How often should panels be cleaned in Mildura?

For most Sunraysia homes, every 6 to 12 months keeps the glass genuinely clean. Sooner if you're near worked vineyards, dirt roads or big trees full of birds. We can put you on a reminder cycle with your window clean so it just happens.

Do I need to be home, and how do I know it's done properly?

You don't need to be home. We text before and after photos of the array with the invoice, so you can see exactly what came off. Payment by card, transfer or cash.
