A solar panel that can rotate in two axis either automatically using four light sensors either manually with the aid of two potentiometers.
Arduino solar panel.
Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma.
Before wiring the solar panel to the arduino we should do a test run using an led first.
Apart pv panel arduino uno board voltage and current sensor different components are used in the experimental setup such us lamps of 100 w that act as a solar simulator a variable resistance between 0 and 300 ω as a load and acting as a light intensity driving.
A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc.
Solar panel charges battery battery stores and supplies power runs arduino.
The arduino mcu senses the solar panel and battery voltages.
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.

Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery.
Solar power can often be a useful solution for powering such devices.
According to these voltages it decides how to charge the battery and control the load.
The amount of charging current is determined by the difference between battery voltage and charge setpoint voltages.
We like our small solar charger kits for these applications.
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.
