Solar panels lose power when they're dirty
Dirt, salt, bird droppings and sea spray all cut how well panels work. When they lose efficiency you harness less power, which defeats the purpose of having them. You're not getting maximum use out of something you've already paid for.
How we clean them
We clean panels with our de-ionised pure water unit, which leaves no mineral film behind. That matters most in towns with hard water, like Whangamatā and Hahei.
Best done with the roof
Panels are usually done with a roof wash and treatment or a gutter clean, so they run at their best over winter. We can also clean them on their own, or while we're doing your windows.
Common questions
How do you clean solar panels?
With pure, de-ionised water, which cleans off salt, dust and bird droppings without leaving a mineral film behind.
Do dirty solar panels really lose power?
Yes. Salt, dust and bird droppings block light, so the panels harness less power and you lose some of what they should be producing.
Can you do the roof at the same time?
Yes. Solar panels are often cleaned with a roof wash and treatment on the same visit.
