DESIGN AND IMPLEMENTATION OF A HYBRID (SOLAR-WIND) POWER SYSTEM FOR STREET LIGHTING IN S.O.T
Abstract
This project focuses on the design and implementation of a hybrid solar-wind power system
tailored for institutional security lighting at S.O.T to mitigate the challenges of unreliable grid
electricity and the high operational costs of diesel generators. The system integrates solar
photovoltaic modules with a Savonius vertical-axis wind turbine (VAWT), which was selected for
its cost-effectiveness, simple construction, and ability to operate efficiently in the low-speed,
turbulent wind conditions typical of urban environments.
Designed for low-voltage DC applications within a 20–36 V range, the system employs a
permanent magnet generator for efficient energy conversion and a charge controller to manage
energy flow and battery protection. The implementation provides a sustainable and continuous
power source for security lighting, specifically within a school environment, thereby enhancing
institutional safety while reducing dependence on non-renewable energy sources.
