IoT Based Solar Power Monitoring System

IoT Based Solar Power Monitoring System – Full Description

The IoT Based Solar Power Monitoring System is a smart energy management solution designed to monitor the real-time performance of a solar power system using Internet of Things (IoT) technology. This system measures key electrical parameters such as voltage, current, power, and energy, and displays the data locally as well as remotely through an online dashboard.

Working Principle

The system collects electrical data from the solar panel using voltage and current sensing circuits. These sensor readings are processed by a microcontroller (ESP32), which calculates power and energy values. The ESP32 then transmits the data to a cloud-based IoT platform over Wi-Fi, allowing users to monitor solar system performance in real time from any device connected to the internet.

A solar charge controller manages battery charging and protects the system from overcharging, while a buck converter regulates voltage for connected loads.
