Ground-source　heat　pumps　are　known　for　their　energy　efficiency　and　potential　to　reduce　carbon　emissions.　However,　the　inconsistency　of　heat　exchange　between　borehole　heat　exchanger　and　soil　in　winter　and　summer　in　heating-dominated　regions　results　in　soil　thermal　imbalance.　To　address　this　challenge,　this　study　investigates　the　integration　of　photovoltaic-thermal　panels　as　auxiliary　heat　sources　with　ground-source　heat　pumps　and　assesses　their　viability　across　different　heating-dominated　regions.　A　system　simulation　model,　which　interfaces　MATLAB　and　TRNSYS,　was　employed　to　evaluate　the　system　performance　under　different　heat　source　combinations.　This　study　delves　into　the　application　prospects　of　these　systems,　considering　various　configurations　and　cooling/heating　load　ratios,　while　assessing　their　energy　efficiency,　economic　viability,　and　environmental　benefits.　The　results　show　that　the　use　of　photovoltaic-thermal　enhances　the　heat　pump　coefficient　of　performance　by　6.5　%,　while　maintaining　the　soil　thermal　balance.　Larger　systems　with　more　panels　yield　better　return　in　regions　with　relatively　high　cooling/heating　load　ratio.　Lower　panel　capital　costs　and　higher　grid　electricity　prices　improve　the　economic　attractiveness　of　the　combined　system　in　regions　with　relatively　low　cooling/heating　load　ratio,　with　life　cycle　cost　reductions　of　up　to　40　%　compared　to　traditional　systems.　The　use　of　these　panels　can　reduce　the　life　cycle　cost　of　conventional　ground-source　heat　pumps　by　more　than　30　%　and　their　CO2　emissions　by　more　than　50　%　with　moderate　capital　costs.　This　study　provides　data　support　and　recommendations　for　the　application　of　these　integrated　systems　in　heating-dominated　regions.　©　2024
