A　new　photovoltaic/thermal　(PV/T)　system　based　on　the　micro　plate　heat　pipe　is　established　in　this　paper,　and　the　experimental　study　is　conducted　for　nature　convection,　forced　circulation　cooling　and　common　PV　module.　the　experiment　carried　out　on　May　showed　that　the　highest　temperature　were　50　degrees　Cand　52　degrees　Crespectively　for　nature　convection　and　forced　circulation　cooling　module,　the　daily　average　electrical　efficiency　were　relatively　increased　by　13.1%　and　6.1%　than　common　PV　modules,　the　total　efficiency　eta(o)　reached　54.2%　and　50.3%,　and　the　primary-energy　saving　rate　were　73.1%　and　68%.the　result　indicates　that　in　the　new　PV/T　system　the　temperature　of　the　PV　modules　is　reduced,　the　electrical　efficiency　is　keeping　at　a　high　level,　and　the　waste　heat　can　be　made　good　use　to　get　hot　water,　therefore　the　solar　energy　utilization　efficiency　was　raised　greatly.
