Solar-powered refrigerators and other solar appliances are commonly used by individuals living off-the-grid. They are able to keep perishable meat and dairy cool in hot climates. Solar refrigerators are very useful as an alternative to absorption refrigerators, as they can be safely left running year-round. The irregular and not constant supply of power in the developing country and non-availability of power grid in the rural communities prevent the use of conventional electrical refrigerator in rural areas. 50cm3 each of water, milk and honey were wrapped put in the solar powered and electrically powered refrigerators for the laboratory bench work. The water, milk and honey samples initial temperature both tin and nylon were 26 0C, 39 0C and 34 0C respectively and readings were taken after every 20 minutes.
