Top Tips On Solar Panel Cleaning And Why You Should Do It

When you invest your hard earned cash into solar panels it's understandable that you would want them to be running at optimum capability so that you can start to recoup your money. However dust, dirt, garden debris (including leaves and bird droppings) all contribute towards decreasing your overall efficiency by preventing sunlight from reaching the solar cells contained within your panels.

Solar panel cleaning

In fact, it's fair to say that the more dirt, the more inefficient your solar panels will become, but just how inefficient? Experts suggest that a loss of solar energy due tolack ofsolar panel cleaning can decrease efficiency by around 33%, and more for those people who have never cleaned their panels. As it's fast approaching winter in Australia now is a good time to put that right.

When it comes to solar panel cleaning it isn't as difficult as you might think. Arguably if you know how to clean windows you can clean solar panels. The hardest part might actually be accessing them. Assuming that you can reach your panels then you should clean the surface of your panels similarly to how you would clean the surface of your car. This is with a mixture of warm water and a mild liquid detergent. Firstly brush off any excess dirt dust and debris, then using a soft brush, dip it in the water and gently scrub, removing any stubborn accumulation of dirt or grime.

In addition if you have any nearby foliage such as trees or hedges then you might also want to make sure that they are trimmed back. Firstly, if allowed to grow they could well impinge on the natural sunlight your panels get, and secondly, if the tree is deciduous, a tree that's been cut back is less likely to shed as many leaves during the winter months and therefore by a law of averages, they're also less likely to end up dropping directly onto your panelling.

So how often should solar panel cleaning be carried out?

The short answer is that there is no defined time scale (say every month or every 3 months). Instead it really does depend upon five main elements and these are:

  • ‍Your location – Do you live in an arid or dry area, or do you get plenty of rain to wash any debris away
  • ‍The angle of tilt – Panels that are tilted tend to accumulate less debris that those which aren't
  • The amount of wind – Wind places and distributes dust and debris far and wide
  • Your electricity rate – If the cost of your electric rate is on the high side then it's more advantageous to clean your panels more often than when costs are lower.
  • ‍Ease of access – If your solar panels aren't easy to access or you aren't particularly mobile then you mightn't want them cleaned as regularly, particularly if hiring a pro is expensive in your area.

In the main it is worth checking on a monthly basis while also monitoring your electrical production.

Reg and Judy

Once again a great job performed by Static. These guys are very professional, friendly and tidy. We have used them on a number of occasions and never been disappointed or had any issues. Thanks to Nathan for his work today.


Great company to deal with - Static are one of the top rated contractors our company uses. I have also used them personally for Airconditioning work at my property. Nathan was very professionally, tidy and informative. Would not hestitate to call them again.

Luke Ehrenberg

Terrific service. Installers came on time, were friendly and efficient, and even cleaned up after themselves !! Absolutely no hesitation in recommending this company, and will definitely use them again

Anne Hattersley

Jeremy arrived on time, in fact he was a little early, he was clean and well presented in his work uniform and very courteous. He asked a few questions about what our air con was doing, to work out what he needed to do, then got stuck into it. His knowledge and attention to detail was impressive and by the time he was finished, our air con unit looked like it was brand new again. Before the cleaning out of the indoor unit, the fan was hardly blowing any air at all, but once the cleaning was finished and with the unit reassembled, Jeremy turned it on to test everything and the fan was now blowing like a force 10 gale, absolutely brilliant, exactly what we had hoped for, we are now all set for the next summer season. We will absolutely totally get Jeremy back at the end of the next summer season to clean the unit again. Top job we can highly recommend this company.
