Solar Panel Monitoring System Using Arduino

Parameters like voltage temperature light intensity and current which are important to monitor.

Solar panel monitoring system using arduino.

More data the better we say at switchdoc labs. The first value 38160 is the current value of the free heap ram available on the esp8266. Solar panel data monitoring using arduino and labview mit this project presents a simple virtual instrument system based on labview and arduino to characterize and monitor a pv panel. In the arduino world a shield is an extension board that is plugged on top of an arduino board.

See how to use the arduino ide with the esp8266 in this posting. To connect the different sensors i build a shield. It s put there to help monitor memory leaks. Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun.

The project requires an ldr sensor for measuring light intensity a voltage divider to measure voltage and a temperature sensor to measure the temperature. It allows you to see exactly what is going on in your solar panel system. The project uses a solar panel to monitor sunlight and arduino board which has atmega family microcontroller attached to it. 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.

Sophisticated solar power systems use mpptcontrollers to monitor and balance the system to maintain the max power point. To check if your system is at this point simply measure the voltage on the solar cell with your load attached to see if you are close to 8v.
