I have given it a serious look, and even gotten some bids, The savings without net metering In Houston, look like they would amount to about $60 to $80 a month,
from about April to October. There would also be minor savings ($30-$40 per month)in the winter months.
Two things stopped me, My wife did not want panels on the front (South) side of the house, and the idea of net metering, I find repulsive.
Solar will be the energy source in future, most likely, but it cannot get there with the current net metering laws.
A system like this one, would do for most homes in Houston.
8.28 kW Grid Tied Solar System with SolarEdge and 24 Astronergy Solar 345 watt Panels | Wholesale Solar
1242 Kwh per month, with a few power walls, it would cover the night hours.
It might also be possible to get one of the electricity packages that provide free electricity at night, but those will change in time.
The bottom line, is that solar must be grid assisted to work like most people are used to electricity working.
People tend to look at how solar pays back, wrong in my book, they look at payback times, I think savings are more important.
If a panel system had a turn key price of $16 K, and resulted in actual savings of $60 a month on average ($720/year),
then that is the same as a savings account paying 4.5% interest, Something I would like to be getting!
