      I have only had them for a couple of months, so I haven’t got that far yet. From some research I have done, I should hose them off once a year. The installer told me that I could probably just hose them off from the ground level, but I’ll probably hop up on the roof and hose them off. I’ll probably do it next spring for the first time.

      I’ve had mine for right at a year. Haven’t done anything, I’ll consider cleaning if I see efficiency taper off

      I’ve had panels for 3 years now. There’s no maintenance needed. Performance is monitored via app and the company that installed them for me will contact me if something is wrong with them for the next 25 years.
