Whether you run a commercial solar panel array or just have solar panels on your house, you’ll want to make sure they’re performing at their best and you’re getting the best return on your investment.
Why clean solar panels?
When solar panels are free from dust and dirt, more light hits the solar cells, meaning more generation, which in turns means more money, faster.
Experts are divided on exactly how much dust and dirt affects solar panel performance, but tests have revealed a decline in output from dirty panels of up to 20%.
Won’t rain clean my panels?
Rain can help reduce the amount of dust on panels, but – just like windows and car windshields – rainfall won’t effectively clean your panels, nor shift algae and bird droppings.
What’s the best way to clean solar panels?
Similar to window cleaning, the most effective way of getting solar panel glass properly clean is to use pure water. Water that’s free from impurities will leave surfaces clean and smear free without damaging panels.
Cleaning solar panels with anything other than pure water – such as detergents or tap water – will leave a deposit on the surface of the panel. This deposit will attract more dirt, effectively making cleaning a waste of time.
The other benefit of pure water cleaning is that it can be done from the ground via water fed poles or cherry pickers, so there’s no need to risk life and limb getting on a roof. It also allows for solar arrays to be cleaned without damaging the panels.
