I do understand the solar industry, that's why I fliped two big middle fingers to them and bought and imported all china solar panels and installed a 5Kwh setup for drastically cheaper than any of the overpriced US crap.
Like anyone else, I will buy the panels which provide the most output for my dollar, and which fit in the space available. But if the world would institute some laws which would penalize countries for slave labor and environmental abuse, then it would cease to make sense to buy a lot of that crap. I sit here surrounded by similar crap, but the point remains.
I use grid intertie and drive the meter backwards. No local storage.
That's certainly cost-effective, but it won't help as much in an outage.
Electrical bill is $14.95 a month because you have to pay the "fees" and the scumbag leaders in my states government passed a law that allows the power company to not pay for any surplus I generate above my own use.
Yes, scumbags are always the problem. Obviously it wouldn't make sense for you to add a lot of battery on the basis of selling power back at shifted times.
