Pi Zero Solar Power - Noob Questions

Folks,



I have been running a camera on a Pi with montionEye for a while, but I would like to relocate it to an area out of reach of a power socket. This means I need to try a solar power and battery solution.



Having done the usual Google research, it seems there are multiple ways of achieving this, so in short I’m looking for some help to get the quickest, easiest and cheapest solution.



The ideal scenario would be :

  • the solar panel and battery combo would power a Pi zero 24/7.
  • the panel would charge the battery when there is sunlight and either the battery or the solar panel would power the Pi.
  • at night, the battery would run the Pi.
  • if the battery runs out, the system would automatically power the Pi back on when the battery has sufficient power



    I think I can achieve this with the following hardware:

    Lipo Rider : https://www.seeedstudio.com/Lipo-Rider-v1-3.html

    Battery : <LINK_TEXT text=“https://www.seeedstudio.com/Lithium-Ion … p-602.html”>https://www.seeedstudio.com/Lithium-Ion-polymer-Battery-pack-6A-p-602.html</LINK_TEXT>



    Can someone please tell me if it’s just a case of connecting these items together and it would just work? Are they all compatible? Does the lipo rider allow charging of the battery while it is also powering the Pi?



    I have probably missed many fundamental issues, so please let me know if I’m way off the mark.



    Thanks for your help.

Hi there~



The main concern is that the power consumption of the pi zero and camera. The pi zero idle power consumption is around 80ma. You had better to add the cirucit to detect the battery voltage and power on/off the raspberry pi zero. You also have to calculate the solar panel size and battery capacity base on the sun light duration and board power consumption. Hope it helps.
