The OP said in the statement you quoted that one of his strategies was to offset electricity if the grid became to expensive. In that case solar could be a decent return.
Also there are alternatives to expensive batteries and there are configurations of LFP batteries available in Texas that do not have the limitations that you experience with Pb in your location. It all depends on where you are standing. BTW, I am not trying to convince you, but rather let other readers see the alternatives.

I agree with you. Where you live and what your electric costs are the main reasons for a financial payback to stored or locally generated energy equipment and usage.
