In　order　to　improve　the　utilization　of　solar　energy,　we　use　the　new　flat-plate　heat　pipe　in　the　solar　photovoltaic/thermal　(PV/T)　system　to　meanwhile　gain　electricity　and　heat.　In　this　way,　the　temperature　of　solar　cell　could　be　effectively　reduced　to　improve　power　generation　efficiency,　and　the　heat　dissipation　of　solar　panel　could　also　be　stored　up　through　the　forced　circulation　of　the　aqueous　solution　at　the　same　time　for　the　hot　water　supply　or　radiant　floor　heating.　We　had　done　the　solar　photovoltaic/thermal　(PV/T)　system＇s　experimental　test　at　the　end　of　heating　season.　The　results　indicated　that　the　totally　heat　generated　from　a　900W　solar　panels　could　meet　the　heating　demand　of　a　15m2　building.　The　instantaneous　thermal　efficiency　of　system　could　reach　25.8%,　the　photovoltaic　conversion　efficiency　is　nearly14.5%　and　the　overall　performance　efficiency　is　up　to　40.3%.　The　solar　photovoltaic/thermal　(PV/T)　system　based　on　the　new　flat-plate　heat　pipe　is　obviously　more　efficient　than　the　photovoltaic　or　solar　heat　utilization　system　alone.　©　2011　IEEE.
