This　paper　presented　a　novel　method　of　dissipating　solar　photovoltaic　heat　based　on　the　technology　of　micro-heat-pipe　array　and　the　utilization　of　photovoltaic-cell　waste　heat.　This　novel　technology　solved　the　problems　of　low　PV　electrical　efficiency　and　thermal　failure　caused　by　high　cell　temperature,　greatly　increased　the　comprehensive　utilization　efficiency　of　solar　energy,　and　extended　the　service　life　of　photovoltaic　modules.　One-year　experiments　were　conducted　to　investigate　the　electrical　and　thermal　performance　of　a　forced-circulation,　household-type　photovoltaic/thermal　system　based　on　micro-heat-pipe　array　in　Beijing,　China.　Test　results　showed　that　on　the　four　typical　days　in　different　seasons,　the　average　electrical　efficiencies　were　13.76%,　11.92%,　13.71%,　and　14.65%;　the　average　thermal　efficiencies　were　31.62%,　33.07%,　24.99%,　and　17.24%;　and　the　average　total　efficiencies　were　45.38%,　44.99%,　38.70%,　31.89%,　respectively.　The　system　met　the　demand　of　power　supply　on　sunny　days　and　the　demand　of　hot　water　between　March　and　November,　except　in　cloudy　days.　These　experimental　results　can　provide　basis　and　reference　for　practical　applications　of　the　system.　(C)　2015　Elsevier　Ltd.　All　rights　reserved.
