The most basic solution is to charge batteries with a solar panel and then connect the batteries to the pi.
Solar panel power raspberry pi.
This guide will show you how to power your raspberry pi using solar panels.
Powering your pi using solar power will allow you to build green pi projects powered by the sun.
Adafruit medium 6 volt solar panel 2 watt.
As some commenters.
And with the right solar panel and battery your project can also run continuously forever.
The neat part though is that this device is being run entirely on a solar panel.
Adafruit industries makes a couple of great products to help you harness the power of the sun including the usb solar charger board and the 6v 3 4w solar panel.
With the appropriate software built into the raspberry pi to protect itself and some medium large solar panels your raspberry pi project can live on indefinitely.
