The concept is kind of analogous in many ways on if one should have solar power to hedge against power outages. I.e definitely can be worth it but will take up time and investment with long payback period.
To hedge against increasing electric utility prices, maybe. I installed solar recently and the cost of batteries to cover a decent power outage didn’t make sense to me. I just got a transfer switch and a portable propane generator instead. The battery tech / price is just not there yet IMO. And in case this isn’t well known, when there is a power outage and you don’t have battery backup, the solar generation shuts off — you’re not using solar AS the backup in most cases unless you have a very particular setup.
