Solar-powered cold storage is a refrigeration system that harnesses energy from the sun to maintain the freshness of perishable goods. Instead of relying solely on the grid or fuel-powered generators, these systems use solar energy through photovoltaic (PV) panels to run. Cold storage warehouses consume three to five times more electricity per square foot than ambient storage facilities. Choosing the right type of panel, whether monocrystalline or polycrystalline, can significantly affect efficiency and energy output. This dependency on electricity makes cold storage. In this paper, a review has been conducted on various types of methods which are available for utilizing solar energy for refrigeration purposes. Solar refrigeration methods such as Solar Electric Method, Solar Mechanical Method and Solar Thermal Methods have been discussed. ____________________________________________________________________________________________________________________ Cut.
