Just curious, do you tinker with small solar panels to recharge batteries for your projects?

I bought a chinese one and its performance is abysmal, so I thought I'd better ask around before buying more ewaste :-/

I'd love a solar powered robot but that seems hard, but wifi modules and control systems should be able to work solar only, right?

They built Acorn with no batteries, only supercaps https://github.com/Twisted-Fields/acorn-precision-farming-rover?tab=readme-ov-file#acorn-precision-farming-rover so solar robots (in that form factor) are potentially viable

Thanks!

Edit: just figured out that it's not that a small robot... That's mountainbike wheels and the solar panels are a 800 Watt grid!
