It's amazing how far a bribe, sorry, lobby money will go, eh. So the gist is, if you get solar, go rogue, cut the cord to the power company, make sure you have enough battery backup to go all night long and a propane tank with generator for emergency power if we get like a weeklong storm or some such.
Before I heard about the payback for selling excess solar power but paying some one penny a kwhr I realized it would not be worth it to overbuild your own solar array, put in just enough to cover your home and charge batteries for nightfall.
Of course that means you need three times the daily need, since you only get 8 hours max of decent solar energy. So if your house runs on say 2 Kw average 24 hours a day, you would need 6 or 7 Kw of solar to cover nighttime assuming you have about 50 Kw hr of battery or so. lets see, 2 Kw for 16 hours, 32 Kwhrs yeah so 50 Kw battery would do it I think. It might be better than that but in Arizona I know OUR AC on the roof ran some 20 hours a day even at midnight. There was a permanent trickle coming off the roof of condensation from that sucker and even IT had to have a cover shield to keep it from overheating. We used to live in Scottdale by the now defunct Los Arcos Mall where we could see the 'hole in the wall'. It turned out not to be a good idea to try to ride a motorcycle up to the hole🙂
Some of that might change since the technology of extracting energy from heat sources is getting more efficient these days, and since your roof would be up to some 200 degrees or thereabouts a subsidiary of black pipes just filled with water could be used to convert THAT to electricity. And there are newer solar cells that generate energy all night long from just the left over heat on the roof at night, maybe 5 or 10% more just from that alone.
