I’m trying to power my Photon with a solar panel. I have a 20V panel, a 3.7V lipo battery, and the Photon power shield (https://docs.particle.io/datasheets/photon-shields/#power-shield). When screw the panel into the power shield, I don’t get enough power to power the shield.
Is the shield designed to work with solar power? If not, what is the best way (if it’s possible) to use the battery and solar panel I have to power my Photon? I’ve seen a few projects using smaller panels but those often use the adafruit solar shield (http://www.adafruit.com/products/390) or something equivalent that use smaller voltage panels.
Thanks for the help!
