This　paper　carried　out　comparative　experimental　investigation　to　test　the　operation　performances　of　a　solar　photovoltaic(SPV)　direct　current(DC)　refrigerator　using　a　phase　change　material(PCM),　a　photovoltaic　DC　refrigerator　without　PCM　and　a　conventional　household　one.　The　solar　photovoltaic　DC　refrigerator　with　PCM　has　many　advantages　on　start-stop　frequency　of　the　compressor,　operation　ratio　and　heat　insulation　time　during　the　motor　stopped.　Furthermore,　the　system　is　powered　by　solar　energy　completely　without　consuming　any　grid　electricity　for　running,　and　is　＂the　green　household　electric　appliance＂　on　real　significance,　that　especially　suitable　for　remote　mountains　and　nomadic　areas　of　fresh　food　and　medical　supplies　of　vaccine,　etc.
