There are many reasons to clean your solar panels including extending the lifetime of your panels, preserving your warranty, saving money on bills and ultimately generating more green energy.

Dirt and lichen build up on solar panels

What makes solar panels dirty?

When solar panels get dirty it is called soiling and a number of factors play into that. The location of your home, the tilt of your panels, rain, wind and surroundings all contribute to the level of soiling that will occur, and ultimately determine the frequency you need your panels cleaned.

Studies have found that at 30 degrees- the average pitch of a house roof – soiling can contribute to, between 5% and 30% of power output loss equating to thousands of dollars over time.

DID YOU KNOW? A common myth about solar panels is that when rains falls it cleans the glass surface. This is simply not true and can be easily disproven by looking at your car windscreen after rain.

What do Solar panel manufacturers say?

Solar panel manufacturers recommend cleaning your solar panels regularly to keep your power output at a maximum, and as a part of an on-going maintenance schedule. Other than physically blocking the suns rays from reaching your solar cells, when panels get dirty they tend to hold the heat more, and the hotter the cells are within the panel the less energy they produce.

Like anything, cleaning your solar panels regularly will keep them in better working order and help them stand the test of time so you can get the best return from your investment in solar power.

Our process

We use water fed tools and water softening technology to ensure you are getting the best streak free clean, that stays cleaner for longer.

Our water deionising systems harness technologies that use a specifically developed ion-exchange resin to trigger a chemical process called electro-deionisation.
This is where the mains water runs through a resin filled tank and charged particles exchange dissolved metals and minerals such as sodium, calcium, iron, copper, chloride, and sulphate, for hydrogen and hydroxyl ions, which then re-combine to form pure water

Our free 8-point inspections

Every solar panel cleaned by Solar Shine Australia goes through an eight-point inspection to determine if there are any faults, failures, and/or hazards.
Our trained and experienced team check for the following common issues.
Cracked or shattered glass, cracks or UV damage to the EVA backsheet, faults in edge seals, and discolouration on the cells and/or busbars.
All of the above mentioned issues are caused by, or lead to moisture inside the panels which poses a number of risks from loss in power output, to fire hazard.

Hotspots or hot cells are burn marks on the busbars and fingers within a cell. This issue is often caused by broken joins, or poor soldering during the manufacturing process.
These defects can lead to heating up and shattering the protective glass, or fire hazard, especially if there is a build-up of dry material such as birds nests, leaves/foliage, etc.

Micro cracks are hairline cracks in the silicone of the solar cell, under the glass, that increase in size over time as heat reacts with them.
Solar panels are actually quite fragile which means these cracks can occur during manufacturing, transport, installation, or naturally during hailstorms.
Microcracks become more visible over time and can eventually lead to hotspots, they will definitely compromise power output and the lifetime of the panel.
We also check that brackets and frames are in the correct position and not damaged, and that cable management is in reasonable order and safe.

Future planning with our solar care plan

Our Solar Care Plan assessment looks at variables that cause solar panel soiling such as surrounding trees, traffic flow, industry, panel positioning, etc, as well as other factors like nesting birds and build up of foliage, to give recommendations on a long-term solar care plan. This plan will guide you to get the most from your solar panels and extend their lifetime.

Why take it from us?

Solar Shine Australia does not repair or install solar panels, so we do not benefit from reporting on faults or damage. We give an experienced and honest opinion on the condition of your panels so you know the state of your system, are utilising your warranty if need be, and are producing the maximum return.
