Solar panel

Battery

Charge Controller

Assembled and tested OK:

  • This battery does not have a programmable on/off cycle, but there is a different model which does.
  • The problem with that is that the battery will deep cycle if it runs all night and charges during the day, which will shorten the battery life. (Maybe there's a way to have the pi sleep and reduce consumption, or at least minimize CPU cycles when there's no solar.
