We put in $60k of solar panels two years ago (tax and utility rebates cut that cost down by half). That functionally makes us neutral. We are in Minnesota, so we get very little output from the solar in the Winter between short days and snow - and there is no way I’m hoeing the snow off $60k of roof mounted panels on a three story house - scratching those panels will degrade the generation. We elected to put in no batteries - any useful batteries for the house would have cost another $10k (this is not a small house and at any given time, there are enough computers running to be a small data center, that would store enough power that if we turned everything off, we’d be able to run the fridge, freezer, lights etc for a day or two - turns out, you can live without power for a day or two) - we may revisit that if our grid gets flaky. Natural gas heat (and dryer and stove).
Now, I don’t think snow would be a long term issue in Texas - a few days of no generation - but those days are going to bring high usage and the Texas problem is the grid failed due to high usage.
