Yeah I was in a scenario some months back where people didn't have access to electricity or gasoline for nearly a week. Some didn't have access to drinking water. It was mildly apocalyptic. I had never seen anything like that and it was a bit stressful having to work but also not knowing if I'd eventually run out of gas before I would have access to it again. Felt like a mini-apocalypse.

Without the power grid to back them up, solar panels are only as reliable as the weather. A week of overcast skies will drain everything you have in your batteries. No output during the night either. There's also the problem of theft, vandalism, natural wear, and the difficulty of finding replacement parts.

If you have solar energy and a way to store it, it should be used for more vital applications, like lights, cooking, and refrigeration.
