Abstract: Conventional refrigeration systems heavily rely on environmentally hazardous refrigerants such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs), which possess a high global warming potential and contribute significantly to ozone depletion. Additionally, these traditional vapour compression systems are mechanically complex, energy-intensive, and prone to wear, vibration, and noise. To address these challenges, this paper presents the design and fabrication of a solar-powered thermoelectric refrigerator. By leveraging the Peltier effect, the proposed system provides a compact, reliable, and eco-friendly cooling alternative without the need for moving mechanical parts or harmful refrigerants. Powered by a solar photovoltaic (PV) panel and supported by a battery bank, this system is particularly suited for off-grid communities, outdoor activities, and the preservation of temperature-sensitive medical supplies in remote areas.
