Cleaning your Solar Panels is a great way to maximise your investment and make sure your electricity bill is as low as possible. Below is some helpful information regarding Solar Panel Cleaning.

How much does it cost to have Solar Panels cleaned?

The price to clean Solar Panels depends on the quantity of panels and the size of the area that needs to be cleaned. The price to clean Solar Panels is usually around $10 per panel. Many times we are able to give the Solar Panels a clean while we are completing a gutter cleaning service and this works out to be cheaper than getting them done separately. Of course each house is different with some requiring more work to gain access, get in touch with us to receive an accurate quote for cleaning your Solar Panels.

How often do you need to clean your Solar Panels?

This depends greatly on where the house is situated. Giving Solar Panels a clean every 12 months will help keep them working at high capacity. If it is an area with a lot of traffic (generates traffic dust) or there are significant bird droppings and leaves from trees you may want to get them cleaned more often, perhaps in 6 month intervals. Most Solar Panels are installed at an angle which allows the rain to give them a good rinse and normally they will be in good condition. However, we find that mould does like to grow on the bottom section of lower panels and if allowed to dry, bird droppings can be quite stubborn to remove. Giving the panels a clean is quite affordable and a good investment.

What happens if you don't clean your Solar Panels?

If bird droppings, mould and other debris are allowed to settle on panels they will reduce the efficiency and output of the system. Solar panels need maximum light to perform efficiently and just as some shade will lower the output of a solar panel system, so will leaves, bird droppings, mould and traffic dust. In Brisbane, we enjoy great sunny weather however we also have a significant amount of thriving trees which not only drop leaves and promote the growth of mould but also provide excellent homes for birds. The drop in output of the panels can be as much as 5%. This means that it's a good idea to monitor your Solar Panels so that they are performing efficiently.

Why hire someone to clean my Solar Panels?

Most Solar Panel companies will advise strongly against cleaning the panels yourself. Why? Because it's high risk work. Cleaning the panels requires the use of water and things can get very slippery up on a wet roof. If there is any residual mould on the roof tiles or Colorbond sheets it will become extremely slippery once wet and poses a significant safety hazard. A temporary anchor point needs to be installed on the roof and connected to with a safety harness. This provides safe fall arrest. Our team are trained in fall restraint and fall arrest and always complete this work in a safe manner. The last thing you want is someone getting injured when cleaning Solar Panels, most of all you.
