Certain food and medical supplies have to be kept in a refrigerated environment at all times, and solar refrigerators are well suited to the storage of such items as it has a constant, uninterrupted cooling effect. An ordinary portable cooler, which relies on a simple cooling system to keep the food cool and not the use of heat dissipation components, so can only keep a few days of cold effect. Most solar powered refrigerators are used to store the energy that is derived from the solar panel system, thereby increasing the overall cooling capacity and cooling time of the refrigerator.
Small wooden houses, residential homes, farms, villas, and even medical clinics are able to get a high benefit from the use of solar energy, which helps to save a portion of the electricity, because they do not require external power to run, and the battery system also allows the solar refrigerator even when the power failure is still able to maintain operation.
