I note you STILL didn't answer the question. It wouldn't hurt you to say "I don't know".
I note you didn't answer the question about how much your photovoltaic output drops when the clouds loom large.

<< Depends how thick the clouds are (attenuation) but it doesn't go to zero.>>

Of course, but near enough for government work, if on a clear blue sunny summer day, one of those nice big fluffy clouds floats over, I guess it drops by half [the blue sky surrounding the cloud will deliver lots of lovely photons]. If you go from that lovely blue sky to a cold front coming over and obliterating the sky, I guess your power output drops by 95%.

Thanks for the offer Eric, but there's a modern thing called Cyberspace. It means people don't have to actually go somewhere to see something and don't have to ask an actual person. << Maybe I can hook you up with a local installer who can explain how pv systems actually work. >>

You can ask Google "Tell me about photovoltaics" and get plenty to be going on with. There's no need to hook up with a local installer. Incidentally, now you remind me, I do know one. Chris worked in the Radio Spectrum group of the government here, managing spectrum. He left and went into the photovoltaics business about 10 years ago.
