Arduino 12v solar panel.
Initially i made a lm317 based charge controller and an energy meter for monitoring the system.
Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma.
The following design is for a solar battery charger ran by an arduino nano.
Play video one year ago i began building my own solar system to provide power for my village house.
It can handle a standard lead acid 12v battery like for a scooter or a car.
Using the percentages calculated above this means i will have 6 7 hours of sunlight for charging time on the shortest day of the year 67 of 10 hours 6 7 hours.
Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun.
Mine are 12v panels with vmp of 18 80 v.
A solar panel that can rotate in two axis either automatically using four light sensors either manually with the aid of two potentiometers.
Calculating solar panel and battery sizes.
This is verified working output and will never damage lead acid battery as the circuit will open and close the mosfet many times per second to average out the output according to measured battery voltage through pin a1.
In this video i will start a project to use solar energy to power esp8266 or arduino devices during the whole year.
Adafruit industries unique fun diy electronics and kits.
Servo controlled light tracking solar panel platform.
Finally i made a pwm charge controller.
