As the global demand for energy-efficient infrastructure grows, the transition toward renewable energy sources has become essential to mitigate environmental impact and reduce operational costs. This project presents the design and development of an automated solar-powered street light system aimed at providing a sustainable and autonomous lighting solution for modern urban and rural settings. The system utilizes a high-efficiency solar panel to harness solar radiation converting it into electrical energy through the photoelectric effect to charge an onboard battery during daylight hours. The core of the system’s intelligence lies in the integration of a Light Dependent Resistor (LDR) and a MOSFET transistor. The LDR acts as a precise ambient light sensor that detects the transition from day to night while the MOSFET serves as an electronic switch that automatically activates the LED street lights when light intensity falls below a specific threshold. By eliminating the need for manual operation and utilizing clean energy, this model demonstrates a significant reduction in energy wastage and maintenance requirements. The findings of this project highlight how fundamental physics and electronic circuitry can be effectively combined to create a cost-effective, eco-friendly and scalable lighting infrastructure capable of operating independently from the national grid.
