Demand for preservation is increasing day by day for applications like food storage, vaccine storage. This calls for design of devices with new technologies which are cost effective and portable. Heating or cooling applications can be achieved using Peltier. A Peltier cooler is a solid-state active heat pump that transfers heat from one side of the device to the other. Peltier’s which are cheap and efficient are being developed by many researchers. This paper deals with the design of a solar-powered vaccine storage refrigerator. As we have seen during the pandemic, vaccine storage has been very challenging, therefore we need efficient vaccine storage systems. Frequent power outages which depend on grid-powered cooling are not practical for vaccine storage. The continuity of the vaccine cold chain is a serious challenge especially in remote areas. Although there have been alternatives, they are plagued by problems with gas supply interruptions, poor temperature control and low efficiency. Therefore, there is a need for solar refrigerator systems, and refrigeration is achieved by the Peltier module.
