Raspberry Pi Solar Webserver





The purpose of this project was to complete a small experimental PV system (max. 70W, 12V, 50Ah) with a corresponding monitoring system capable of making data visible on the internet. The other purpose is to make this system additional educational note for myself and for the others that could be interested. It might be interesting to say that the budget for all electrical materials used (except the panels and battery) is fewer than 50 dollars. 
The main system components used are:
- Raspberry Pi B+
- HD4470 4x20 LCD
- 3.3<->5V bidirectional converter
- Arduino Nano
- Hall current sensor module
- Solar charger regulator (10 A)
- Used car battery (12V 50 Ah)
- Cables and other items (see the diagram)

The end result the webpage running from a webserver which consumes less than 2 W of energy and a reliable monitoring and control system with endless possibilities, at extremely low budget!


The described webserver is currently (hopefully with help of the sun) running on this adress: vladorpi.ddns.net

You can see some other details and photos on that page.
