Design and Development of a Portable Hybrid Solar-Wind Power Generation System for Sustainable Off-Grid Applications

Renewable energy is a clean and sustainable alternative to fossil fuels, offering solutions to environmental and energy challenges. This research presents a portable green power generation system based on a hybrid combination of solar and wind energy. The system is designed to supply AC power for low-load applications, particularly in outdoor or off-grid scenarios. It integrates six main components: a solar photovoltaic panel, a solar panel, a micro wind turbine, a hybrid charge controller, a battery, and an inverter. The photovoltaic module captures solar radiation, while the micro wind turbine converts wind energy into electricity using a permanent magnet generator. A solar optimal panel orientation to maximize energy absorption. Energy is stored in a compact battery and managed by a hybrid controller to prevent overcharging and deep discharging. An inverter converts the stored DC power into an AC output suitable for common electrical devices. The final prototype measures, making it practical for portable use. The system achieved an efficiency of 88.38% with room for further improvement in reducing errors and enhancing energy output. This paper demonstrates the feasibility of hybrid renewable energy systems for portable applications and highlights their potential for sustainable and clean energy solutions in real-world conditions.
