You need to be in the Seattle area.

I've never had to clean my PV's.

Just enough rainfall here to keep them very clean.

I did an experiment about 12 years ago where I measured very carefully the output of some of them and then I washed them.

Virtually no difference in output after correcting for temp and solar irradiation.

The only problem was when tree pollen season was going on. Until the first rainfall after that period in our March, April timeframe here there was reduced output. Maybe about 10% at worst.

Then why are we buying solar stuff from China i/o Germany?

"what did Obama do with W's 167 solar panels?"
Since Obama was pressured by greens to put solar panels on, why didn't he point out there were already these solar panels? Maybe they're not there anymore.
