A solar refrigerator operates almost exactly the same as the one you have in your kitchen now, with the exception that is powered by both solar and conventional electricity. They are powered by solar photovoltaic arrays (solar panels) and DC or AC/DC power as a back up energy source. Made from environmentally friendly (non-CFC) materials, solar refrigerators are designed to last a lifetime, and should never need to be replaced.
