They are so predictable, the slightest hint of something being difficult they give up and say it can't be done. We'd still be living in caves rubbing two sticks together if it was up to you guys.
So it might be cloudy sometimes. Well maybe there is a way to store electricity when there is a surplus and feed it out again when there is high demand. There are dozens of technologies available to do this from batteries to pumped storage and everything in between (oh yes I know someone will reply to me to say that won't work because conversion losses or whatever so we shouldn't bother).
Also this grid thing might be a good idea, that way if it is sunny in one place but cloudy in another people can share (but oh no it won't completely replace all nuclear coal and gas fired power stations in the whole US so we shouldn't bother).
Do you know how many new houses were built in the last decade housing boom? I don't know either but just consider if even a small PV panel of a couple of square meters was on each one, the cost would be much less through economies of scale and it would make a significant dent in energy demands (but oh no it won't completely replace all nuclear coal and gas fired power stations in the whole US so we shouldn't bother).
And yes most states now have laws that prevent HOAs restricting the use of PV.
