Touhidul Islam Department of Electrical and Electronic Engineering, University of Rajshahi, Rajshahi-6205, Bangladesh ABSTRACT We have Developed an IoT-based real-time solar power monitoring system in this paper. It seeks an open- source IoT solution that can collect real-time data and continuously monitor the power output and environmental conditions of a photovoltaic panel.The Objective of this work is to continuously monitor the status of various parameters associated with solar systems through sensors without visiting manually, saving time and ensures efficient power output from PV panels while monitoring for faulty solar panels, weather conditionsand other such issues that affect solar effectiveness.Manually, the user must use a multimeter to determine what value of measurement of the system is appropriate for appliance consumers, which is difficult for the larger System. But the Solar Energy Monitoring system is designed to make it easier for users to use the solar system.This system is comprised of a microcontroller (Node MCU), a PV panel, sensors (INA219 Current Module, Digital Temperature Sensor, LDR), a Battery Charger Module, and a battery. The data from the PV panels and other appliances are sent to the cloud (Thingspeak) via the internet using IoT technology and a Wi-Fi module (NodeMCU). It also allows users in remote areas to monitor the parameters of the solar power plant using connected devices. The user can view the current, previous, and average parameters of the solar PV system, such as voltage, current, temperature, and light intensity using a Graphical User Interface. This will facilitate fault detection and maintenance of the solar power plant easier and saves time. KEYWORDS Internet of Things (IoT), Node MCU, PV Solar panel,Current sensor Module,Things peak 1. INTRODUCTION The Internet of Things (IoT) is a technological advancement that connects computing devices, machines, and objects in everyday life with special identifiers and data transfer over a network without requiring human-to-human or human-to-PC communication. This technology facilitates data exchange between connected devices on a network. The internet enables users to access data and control devices from anywhere in the world. The main goal of the Solar Power Monitoring System is to promote a data acquisition system that continuously appears remote energy yields. Electricity is required in today's world for heating, lighting, refrigeration, transportation systems, and all home appliances. The graph of energy consumption is increasing day by day, while the graph of energy resources is decreasing. So, in order to balance the electricity deficit, we are using renewable sources such as the sun, wind energy, and tidal energy to generate electricity that can be reused instead of non-renewable sources such as coal, natural gas, and fossil fuels, which are depleting on a daily basis. That is why solar power is referred to as an indestructible energy source. As a result, an IoT-based solar power monitoring system is being proposed to address the issues associated with electricity scarcity.
