Arduino 12v solar panel.
Servo controlled light tracking solar panel platform.
Initially i made a lm317 based charge controller and an energy meter for monitoring the system.
We wll answer the following questions.
Finally i made a pwm charge controller.
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.
Any 12v solar panel.
The following design is for a solar battery charger ran by an arduino nano.

In this video i will start a project to use solar energy to power esp8266 or arduino devices during the whole year.
It can handle a standard lead acid 12v battery like for a scooter or a car.
Arduino solar charge controller version 2 0.
A solar panel that can rotate in two axis either automatically using four light sensors either manually with the aid of two potentiometers.
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.
