HYBRID

This project aims to design and implement a hybrid clean and renewable energy system for telecommunication base stations, integrating wind and solar energy sources. The primary purpose is to enhance the sustainability, reliability, and efficiency of off-grid power systems, particularly in remote locations where traditional energy sources are costly and environmentally unsustainable. By leveraging the complementary nature of wind and solar resources, the project seeks to reduce dependence on fossil fuels, minimise carbon emissions, and improve the energy autonomy of telecommunication infrastructure. The ultimate goal is to create a resilient, ecofriendly energy framework that contributes to global efforts in combating climate change. The methodology involved an extensive research and development process. Initially, a detailed literature review was conducted to gather insights from existing studies and identify areas for improvement. The design phase focused on developing a dual-input charge controller system capable of managing power from both solar panels and wind turbines. The system architecture incorporated essential components such as voltage and current sensors, metal￾oxidesemiconductor field-effect transistor (MOSFET) drivers, and a battery storage unit. A prototype was simulated using Proteus Computer-Aided Design (CAD) software, followed by the construction of the physical model. The wind turbine was crafted from a modified fan motor, while the battery pack consisted of lithium-ion cells configured for optimal capacity. System testing was conducted under varying environmental conditions to evaluate performance and reliability. The results demonstrated that, while the solar system consistently generated higher energy outputs, the wind turbine provided supplementary power, particularly during periods of low sunlight. The hybrid system showed potential in maintaining stable power generation throughout different times and seasons. However, challenges in wind turbine fabrication affected overall efficiency. The study concludes that integrating wind and solar technologies enhances the resilience and sustainability of telecommunication base stations. Recommendations for future work include improving wind turbine fabrication, expanding testing across diverse climates, and exploring additional renewable energy sources to further bolster system autonomy and efficiency.

This research presents the design, development, and implementation of a hybrid online marketplace tailored to the needs of local communities in Nigeria. The platform is developed to bridge the gap between informal local trade and modern digital commerce, providing a flexible solution that integrates both online and offline transaction models. It empowers users— particularly students, artisans, and micro-entrepreneurs—to list, promote, and sell goods while buyers can browse, compare, and purchase items within their geographical areas. The system was built using ReactJS for the frontend, Firebase for backend and real-time database operations, and integrated with payment gateways such as Paystack and Flutterwave for secure transactions. Core features include user registration, product upload, search and filter tools, messaging, hybrid payment options, and an admin dashboard for moderation and analytics
