The medicine and vaccine require to store in the refrigerator the continuous provision of electrical energy is required so that their efficacy is not affected. This represents an important problem for rural areas where there is no continuous electrical energy. In this work, we design a solar energy system for refrigeration of cold storage medicines to be used in rural towns without giving continuous electrical. The system uses a thermoelectric refrigerator based on the Peltier effect, which produces a temperature difference when electrical power is provided to it. It will be shown that for a typical application for vaccine refrigeration, the required solar panel is about 100W peak connected to batteries with a storage capacity of 20Ah. The designed refrigeration system has a 14-liter volume capacity of vaccines at temperatures in the range of 14° to 15°C using a Peltier cell (TEC) that consumes 28 W at 12V.
