Solar Panel Monitoring Using Arduino

Prototype of arduino based solar panel electrical parameters monitor.

Solar panel monitoring using arduino. A single arduino mega 20 4 lcd arduino sd card module and 2 small solar panels are part of the project. The monitoring of these parameters are also important in households too. The acquisition is made through a low cost current and voltage sensors and data are presented in excel by using the plx. This project by a final year student from university of liverpool is about monitoring the solar energy emitted by sun using solar panels and arduino.

Initially i made a lm317 based charge controller and an energy meter for monitoring the system. 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. Arduino solar charge controller version 2 0. I have always been interested in measuring the exact angles for ideal solar energy collection.

A pv panel arduino uno board voltage and current sensors are used as hardware components. Calculating solar panel and battery sizes. So here we discuss on how to monitor solar panel parameters. Solar panel data monitoring using arduino and labview.

The system design is based on a low cost arduino acquisition board. Smart solar panel with arduino. Now we will calculate the size of the solar panel and battery to power my circuit that draws 23 ma. Also for monitoring its output data current voltage and power under real condition.

I was looking for a way to measure and record these ideal angles and finally decided it would be fun to just build my own. Data acquisition and logging is also part of the project. Finally i made a pwm charge controller. The b25 voltage sensor uses the principle of the voltage divider it is essentially a voltage divider using a resistance of 30 kω and a resistance of 7 5.

For this project reader should have knowledge about how to start with arduino and interface lcd with arduino. Calculating solar panel and battery sizes. Solar panel monitoring arduino sketch writing a program for the arduino was a new experience for me. Spoiled by windows linux and even android which have basically no memory limit i run very soon into problems with the very limited code and variable space on the arduino boards.

Play video one year ago i began building my own solar system to provide power for my village house. For measuring the pv panel s output voltage the b25 voltage sensor module is used figure a. This project proposes a low cost real time virtual instrumentation system based on labview and arduino to characterize a pv panel. This project proposes a low cost way of virtual instrumentation for real time monitoring of the pv panel characteristics such as voltage current and power.
