The Preservation of Temperature-Sensitive Pharmaceuticals Such As Insulin Requires Strict Cold-Chain Maintenance Between 2°C And 8°C To Prevent Degradation of Biochemical Stability. In Developing Regions, Unreliable Electricity Supply And Inadequate Infrastructure Frequently Result In Cold-Chain Interruptions, Compromising Drug Efficacy And Patient Safety. This Research Presents The Comprehensive Design, Mathematical Modeling, Fabrication, And Experimental Evaluation of A Portable Solar-Powered Thermoelectric Refrigeration System Intended For Rural Healthcare Applications. The System Integrates A TEC1-12706 Thermoelectric Module Powered By A 20W Photovoltaic Panel With Lithium-Ion Battery Storage And Closed-Loop Temperature Control. Detailed Thermal Load Calculations, Energy Balance Modeling, Coefficient of Performance Analysis, And Transient Cooling Behavior Are Investigated. Experimental Results Indicate Cooling From 29°C To 4.8°C Within 58 Minutes Under No-Load Conditions And Stable Maintenance Within WHo-Recommended Range For 4.5 Hours on Battery Backup. The Proposed System offers A Compact, Environmentally Sustainable, And Maintenance-Free Alternative To Vapor Compression Refrigeration For Decentralized Medical Cold Storage.
