Arduino Red Board Solar Panel Measurements

The heart of the charge controller is an arduino nano board.

Arduino red board solar panel measurements.

Project tutorial by jeffrey. Voltage is measured by the help of a voltage divider circuit as the arduino analog pin input voltage is restricted to 5v i designed the voltage divider in such a way that the output voltage from it should be less than 5v my battery used for storing the power from the solar panel is rated 6v 5 5ah so i have to step down this 6 5v to a voltage lower than 5v. Arduino s analog inputs can be used to measure dc voltage between 0 and 5v when using the. Play video one year ago i began building my own solar system to provide power for my village house.

Solar panels mppt solar panel regulator controller. The mini solar panel. The solar panels need to generate 266ma on average during the daylight hours but the one i chose a 12v 3w panel only generates about 210ma max in the usable voltage range so two need to be paralleled which yields 420ma which is well over the current required for that winter day in louisville. You may use various batteries that has the voltage of 3 0v 4 2v to shift up for 5v output or put on li ion battery and solar panel to form an autonomous sensor unit.

Measuring solar radiation with arduino. This device keeps a flat panel holding a solar cell continuously following the sun as it moves across the sky. Initially i made a lm317 based charge controller and an energy meter for monitoring the system. The arduino senses the solar panel and battery voltages by using two voltage divider circuits.

Well make your own device with your arduino board using this guide. Arduino mega 2560 r3 board. Arduino solar charge controller version 2 0. Want to measure solar radiation but cant afford a pyranometers.

The solar charger is a stackable shield to arduino compatible platforms enables adaptive battery power and act as energy harvester for in field charging. Finally i made a pwm charge controller. We have performed a basic measurement test and we have also added the voltage measurement with an arduino mega 2560 r3 board and visualization and data collection with node red and node red dashboard. The arduino uses 2 light dependent resistors ldrs that are separated by a fin to compare the light levels on either side and then rotate the servo attached to the panel towards the more illuminated ldr until the two detectors are equal.
