Arduino Red Board Solar Panel Measurements

Initially i made a lm317 based charge controller and an energy meter for monitoring the system.

Arduino red board solar panel measurements.

Well make your own device with your arduino board using this guide. 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. According to these voltage levels it decides how to charge the battery and control the load. Arduino s analog inputs can be used to measure dc voltage between 0 and 5v when using the.

The heart of the charge controller is an arduino nano board. This device keeps a flat panel holding a solar cell continuously following the sun as it moves across the sky. Measuring solar radiation with arduino. Project tutorial by jeffrey.

Components arduino duemilanove board 12v solar panel 1n4007 diode 25v 100uf capacitor 9v rechargeable battery and connector a breadboard and some wires suggested red and black a multimeter to measure tensions 1 green power arduino datasheet suggests us to power it with 6 20v being aware that the upper limit could be dangerous. The mini solar panel. Play video one year ago i began building my own solar system to provide power for my village house. The arduino senses the solar panel and battery voltages by using two voltage divider circuits.

Want to measure solar radiation but cant afford a pyranometers. 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. 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. Arduino solar charge controller version 2 0.

Solar panels mppt solar panel regulator controller. In this system solar panel will move in the direction of sun from sun rise to sun set. Arduino mega 2560 r3 board. The solar charger is a stackable shield to arduino compatible platforms enables adaptive battery power and act as energy harvester for in field charging.
