The most basic solution is to charge batteries with a solar panel and then connect the batteries to the pi.
Build solar panel system to power raspberry pi 3.
Connecting the solar panel to the pi zero.
Powering your pi using solar power will allow you to build green pi projects powered by the sun.

Building a solar powered pi is a surprisingly easy task.
This guide will show you how to power your raspberry pi using solar panels.
They re cheap and you can buy them anywhere.
Most solar panels in the market today are 9v.
And with the right solar panel and battery your project can also run continuously forever.
This is a peak 4w solar panel and the raspberry pi generally uses about 1 4w without any add ons so it should be possible to run indefinitely with direct sunlight.
Touching the exposed metal on this is definitely ok.

This he figured would gather energy from the sun to charge a 12 v battery and with the use of an inexpensive 12 v to 5 v buck module power the raspberry pi 3 model b and an eight megapixel raspberry pi camera module v2.
The neat part though is that this device is being run entirely on a solar panel.
The power bank should output at least 2a for the raspberry pi 3 2 5a for the raspberry pi 3 b or 1a for the raspberry pi zero.
The 9v solar panel has a male dc connector on it the sleeve is the negative and the tip is the positive.
