Smart Rooftop System

Abstract

Urban buildings use a large amount of electrical energy every day, especially for cooling. One common reason is the heat absorbed by rooftops, which directly affects indoor temperature. In many buildings, the rooftop area is simply left unused, even though it receives sunlight for most of the day. This increases the cooling load and leads to higher electricity consumption from the grid. To deal with this issue, we developed a smart rooftop system by combining solar photovoltaic panels with an IoT-based monitoring setup. The solar panels are used mainly to supply power to the system. Sensors are placed on the rooftop to measure temperature and to check whether the system is operating properly. A microcontroller is used to read this sensor data and display or monitor the conditions in real time. Based on these values, basic decisions can be made to understand rooftop performance. The purpose of this work is not only power generation, but also better utilization of rooftop space. During practical testing, the system showed improvement in energy usage and reduced unnecessary power consumption. The setup is simple and does not involve complex construction, which makes it suitable for normal buildings. This system can be implemented in both residential and commercial environments with minimal changes to existing rooftop structures
