One of the first things I bought for my Raspberry was a battery hat, it’s great. When the power goes out, it keeps on trucking. I would love to add a solar panel or wind turbine as an extra power source.

Yeah! That has been my idea for a long time! When thought about it, I began looking into devices that can output DC and charge a backup battery but with a variety of input power sources, Solar as main source and line AC as backup. Didn't get that many practical search results.

But it seems what I was looking for are boat chargers. They're meant to provide energy through solar/battery and charge at the same time while parked on a deck. Didn't followed it up though.
