Best way to clean solar panels?

Hi everyone. I have an old solar hot water system on the roof and I've noticed it has got algae or something growing on it. Is there anything I should or shouldn't use to clean it? I've been putting it off as I'm not too keen to get up on the tiled roof as it could be slippery. I guess something that I could spray from a distance and stay on the relative safety of the ladder would be preferable. Thanks!

I found some on our old system that was in a corner from a leak - new system later only a bit of mould on a mounting bracket and no leak.
I would try a gentle spray with a garden hose first.

@Mick2

I've seen this stuff around and perhaps this might be useful. Not sure if they stock it at Bunnings though, but you could ring your local one and ask:
