Your Solar Shields still aren’t available in the store yet, and have something coming up that can’t wait so looking at alternative locations. What are the specs, dimensions for individual replacement? All I see is “6-watt monocrystalline solar panel”. Anything further I need to know or just go pick one up?
Performing a 6-week trek away from power sources and follow movements with information of where I’m at. This is for study & research.
I have one of the kits. The adafruit panels (from Voltaic) you link to are pretty close to what came with mine: LINK.
Once you get a solar panel, I think you still need a regulator to deal with incoming voltage, although I may be wrong about that depending on what voltage your panel outputs and what the electron can deal with onboard. The solar kit shield looks like it has a regulator that can deal with up to 32V.
