In this webinar, there's raspberry Pi powered time-lapse cameras across a watershed / prairies. One of the time lapse segments shows a camera tech working on the device. At about 9, 13" to ,30" into the video there's an OK view of the hardware, try zooming in. He doesn't say what was done for the set up of the solar power for each unit, like what batteries. Some of the animal shots were motion generated, by the camera unit?
Good lapse sequences at 7" and about 25" - 27".
