It’s coming to the time of year that we get reduced cloud cover and a lot more sunshine. This will mean that our solar panels will start to generate more power again, which is helpful. It’s been quite a while since I last cleaned them, so last weekend I picked up a soft bristle brush to have a go at cleaning them.
The last few times that I have cleaned the panels I have just hosed them off, letting the water pressure from the hose do the work of cleaning the solar panels. However this year I’ll be giving them a scrub to really clean them up.
I was curious about what kind of performance increase I would get from cleaning them, and after watching the below video, I reckon it’ll be pretty significant. Paul on the video managed to get a performance increase of about 30 – 40%!
Cleaning the solar panels should help a lot, especially with the ridiculous high cost of electricity here in South Australia…



75% of Australian homes have air conditioners, which will be the households most affected by the increase. Because of the harsh climate that we have here in South Australia that percentage is even higher at 90%. The “critical peak surcharge” could be applied on the hottest days, for up to 4-hours.
