It is built up of 2 main parts.
Arduino red board solar panel measurements.
First of all please bare with me.
At sun of 10 30am the maximum value of the solar panel is 21v although the characteristics indicate and guarantee 18v max without connected load it is normal that it generates 21v.
Project tutorial by jeffrey.
The one used in this project is a 9 gram analogue servo.
Emergency household lighting using power leds powered by the solar panel and lead acid battery.
The system uses non invasive ct sensors to measure the current.
Installation node red platform.
In this system solar panel will move in the direction of sun from sun rise to sun set.
The specific servo model or size has not been stated as it depends on the size and weight of your solar panel.
Just connect the solar panel output voltage to analog pin of arduino and convert that in digital and display result on lcd or computer.
Battery capacity is 1300mah c 10 130mah the solar panel has to provide current 100mah for arduino along with a current not more than 130mah.
Battery voltage 1 2 x 2 2 4v so required voltage for solar panel 2 4 x 1 5 3 6v by taking some margin we can choose a 4v solar panel for it.
The raspberry pi running as the main controller and an arduino which takes care of moving the servos and taking the light measurements.
Well make your own device with your arduino board using this guide.
The sensor module along with arduino taking 100mah current.
Want to measure solar radiation but cant afford a pyranometers.
Measuring dc voltage with arduino and node red.
And suppose if you want to measure up to 10 volts then you have to use the given circuitry.
So we do not have to temper directly with the 240v or 110v lines.
No start search for arduino board in the local network yes start the main activity search for arduino board successfull.
Arduino yun solar panel monitoring system.
For measuring voltage we have to follow the given formula.

This project is a solar tracker with live data feed powered by the windows iot core running on the raspberry pi 2.
