A friend of mine pressure washes his every year, and he's in his 60's. I've never cleaned my 30 year old metal roof. There's little to no mold on it, at least last time I checked.
Solar panels have been noticeably dirty enough to prompt cleaning a couple times. Rubber soled shoes or boots have pretty good traction on metal.
