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.
Spent 1/2 the price got the same panels all monocrystalline and of very good quality build. It's been in operation for 3 years now with no problems. I use grid intertie and drive the meter backwards. No local storage.
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.
