    Depends on where you live in Texas. My solar panels cut my summer bill in half, and my winter bill is usually zero.

    If my power company didn’t pay me a decent buyback amount, I’d invest in an enphase battery and offset the cost of running appliances at night.

      That’s fair. In ONCOR territory, the buyback offers I had last time I renewed a plan were either a fraction of what you pay but no limits on how many kwh you can sell, or what you pay your REP but capped to a comically low number of kwh a month, or the wholesale rate at the time the kwh was put back on the grid.

      Essentially the options are shit, probably shit, and almost certainly shit.

      I did the math on the batteries, and the solar install would have been like four times the cost it was without batteries: ~$8000 for the panels, but nearly $20k more for enough batteries to provide peak load and sufficient storage along with the added installation costs for the batteries.

      Problem was/is that even at $0.13/kwh to pull from the grid, the payback time was basically a decade longer than the batteries are going to last based on how much power I actually use, so shitty buy back or find some way to burn the extra power it is, then.

      (Disclaimer: prices probably have changed in the past 3 years, but probably not enough to make the math wrong.)
