Waveshare Solar Power Manager Module (D) is a compact power module for solar panels with support for 6V to 24V input, MPTT (Maximum Power Point Tracking),
Looks like it could power anything that needs 5v, as long as you have the panel energy. A built-in regulator for 3.3v would make this an insta-buy for me.
