Abstract

The rapid growth of renewable energy sources, particularly solar power, has created a need for efficient real-time monitoring systems. This paper presents an IoT-based Solar Power Monitoring System designed to measure and remotely monitor key electrical and environmental parameters of a solar panel installation. The system use an ESP32 microcontroller interfaced with a voltage sensor, current sensor, and DHT11 sensor to acquire real-time data. The measured parameters voltage (V), current (A), power (W), and temperature (°C) are transmitted over Wi-Fi to the Blynk IoT cloud platform, where they are displayed on a mobile/web dashboard using gauge widgets. A 16x2 LCD display provides local data readout. The hardware prototype uses a 12V/25W solar panel with an LED bulb as the load. Experimental results demonstrate the system successfully monitors voltage up to 20V, current up to 2A, power up to 25W, and temperature up to 70°C in real time. The proposed system offers a cost-effective, scalable, and user-friendly solution for solar energy management.
