Raspberry Pi and a Powerbank with Pass Through charging for solar powered projects
here is my contribution for solar powered RPI projects.

using a raspberry Pi for small projects that are solar powered you can use a powerbank with pass through charging for powering the RPI.

the **power path** can be
solarpanel  -->  powerbank   -->  RPI 1/2 /3 + wlan stick

**requirements**
*solarpanel*  
voltage  5V / current 2A / power output 20W, monocrystaline Modules 
for example SunPower Modules with USB connector
*powerbank*  
voltage 5V / current 2A / capacity 20Ah


**advantages**
- ups function for RPI
- the RPI works 24 hours a day powered by the powerbank
- the solarpanel delivers power that can be saved in the powerbank


**possible solarpanel**

with a **usb multimeter** you can measure the power output of the solarpanel
