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.

Be aware to not hose them off when they have been exposed to sunlight for a certain amount of time. Solar panels become extremely hot and cold water will crack the glass panel.

Thanks for the reminder! The installer also warned me about this.

Water your panels like your garden

Wouldn't rain rinse them at least once a year? Unless you live in the desert of course.
