According to Gordon, it may be a good idea, but may have to add an anti mossing agent to the water supply!! :idea:

You also need access to a large cheap water supply. I have done water cooling tests and it certainly increases output in warm to hot weather, but I only have rainwater from the roof, so my water is more valuable than a few extra watts PV output that I don't need in sunny weather anyway!
I don't think it is a good use of an urban water supply either, but if you collect water on your roof and have an excess that would normally just go down the stormwater drain, that would be a good use for it. Just make sure your pump doesn't use more energy than you gain from the cooler panels ;)

I just rinse mine off. Dust never affected its performance though. I just wanted it to look its best. :)

Proactively rinsing from time to time will help prevent the buildup of difficult-to-remove gunk.

Folk on here have set up circulatory systems... Mist Sprayers, and collect the water and reuse...

It is clearly beneficial, and the energy harvested, far outweighs the power to run the pump/s... :D
