Furthermore the design has been tested and runs with 90 efficiency under 70ᵒc 158ᵒf.
Arduino 12v solar panel.
Initially i made a lm317 based charge controller and an energy meter for monitoring the system.
It can handle a standard lead acid 12v battery like for a scooter or a car.
In this video i will start a project to use solar energy to power esp8266 or arduino devices during the whole year.
Calculating solar panel and battery sizes.
The following design is for a solar battery charger ran by an arduino nano.
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.
Mine are 12v panels with vmp of 18 80 v.
Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma.
A solar panel that can rotate in two axis either automatically using four light sensors either manually with the aid of two potentiometers.
Play video one year ago i began building my own solar system to provide power for my village house.
Finally i made a pwm charge controller.
