Abstract: The energy supply sector for buildings accounts for approximately 40% of worldwide CO2 emissions, highlighting the importance of decarbonizing these systems to address the threat of global warming. In this respect, utilizing Ground Source Heat Pump (GSHP) technology is an effective and practical approach to reduce carbon emissions by enhancing energy‐based performance. The benefits of GSHP units can be further realized when combined with renewable energies. A new scheme of GSHP system, with a cascade heat pump cycle, is proposed in this work in which the consumed electricity is supposed to be supplied by clean solar photovoltaic panels. Technical feasibility (based on thermodynamic laws) and economic profitability of developed PV‐GSHP plant are analyzed and a comparison is made with conventional GSHP system. In addition to assessment of the effects of operational and design parameters, the study represents the impacts of geographic conditions and different working fluids. The results indicated that the working fluid selection has a considerable impact on the performance of the novel PV‐integrated GSHP system. Also, the numerical findings demonstrated greater exergy efficiency and COP, respectively by 4.3% and 16.6% for the novel plant rather than the conventional system. In addition as an interesting outcome, it is shown that the novel integrated plant has lower cost of product (heating) by more than 19%, in spite of more number of components in cascade heat pump unit.
