In　order　to　assess　the　comprehensive　performance　of　photovoltaic　thermal　system　based　on　micro　heat　pipe　array　(MHPA-PV/T)　systems　in　different　regions　of　China,　the　mathematical　model　of　the　system　was　built.　The　reliability　of　the　model　was　verified　through　the　experimental　data　of　four　typical　seasons,　and　the　simulated　results　agreed　well　with　the　experiment.　Then,　this　model　was　used　to　predict　PV/T　system　performance　in　five　typical　cities　of　different　regions　in　China.　For　the　MHPA-PV/T　system　of　two　195W　peak　power　modules　and　the　100L　capacity　heat　collecting　water　tank,　model　prediction　results　shows　that　the　average　thermal　efficiency　in　Beijing,　Changchun,　Nanjing,　Haikou　and　Xining　were　respectively　28.5%,　27.8%,　27.3%,　31.5%　and　28.3%,　average　electrical　efficiency　were　13.6%,　13.9%,　13.8%,　13.3%　and14.0%,　the　total　efficiency　of　solar　energy　utilization　were　respectively　42.1%,　41.7%,　41.1%,　44.8%　and　42.3%,　the　total　generation　capacity　were　415.7kW.h,446.9kW.h,　372.8kW.h,325.7kW.h　and　471.8kW.h,　the　ratio　of　solar　heat　supply　and　demand　were　respectively89.6%,.　79.9%,84.0%,　105.8%　and　80.5%.　(C)　2015　The　Authors.　Published　by　Elsevier　Ltd.　This　is　an　open　access　article　under　the　CC　BY-NC-ND　license　(http://creativecommons.org/licenses/by-nc-nd/4.0/).
