DESIGN AND CONSTRUCTION OF A SOLAR POWERED REFRIGERATION SYSTEM
Abstract
ABSTRACT
This project presents the design and construction of a solar-powered refrigeration system tailored for off-grid and weak-grid communities. The system integrates photovoltaic (PV) modules, a charge controller, an energy storage unit, and a high-efficiency DC refrigerator. A comprehensive methodology was adopted: load assessment, PV-array sizing, battery storage sizing, component selection, construction, and testing. Simulations and experimental tests show that the prototype maintains compartment temperatures within 2–8°C while meeting daily energy needs under typical solar conditions in Nigeria. The work demonstrates technical feasibility and provides design guidelines for deployment in rural healthcare and household applications.
