Solar Hybrid Cold Storage

Technology Details
 Solar Hybrid Cold Storage

This intervention addresses the critical need for decentralised cold chains by deploying a Hybrid Solar Cold Storage system optimised for any climate. Distinguishing itself from standard solar refrigeration, this system eliminates the use of expensive Phase Change Materials (PCM) in favour of a novel Sensible Thermal Energy Storage (STES) mechanism using high-specific-heat fluid buffers. During peak solar irradiance, the PV array supercools the thermal mass, creating a thermal bank that maintains the requisite preservation temperature (approx. 4-12°C) during non-solar hours. This thermodynamic decoupling significantly reduces the reliance on electrochemical battery storage, lowering Capital Expenditure (CAPEX) by approximately 30%. The result is a robust, grid-independent asset that enables Self-Help Groups (SHGs) to extend shelf life and mitigate distress selling without incurring prohibitive operational costs.
