If one chooses the correct type batteries and a medium high (like 20 watt) solar panel with charger for A, AA, AAA, D rechargeable batteries, one can live quite well, which I do when a hurricane comes through. I could live well for as long as it took to return to normal. Planning and carrying out that plan is key.
That is not the only prep one would need but planning can also give one a renewable way to have pure water, a way to cook forever, stay cool, stay warm, and stay safe.

Didn’t say you couldn’t live, just said you couldn’t live the normal life you are used to.
How many “D” batteries does it take to run your refrigerator for a week so your food doesn’t spoil?
Rechargeable batteries will work....for a while. But they all die in the end.
