This paper evaluates configurations of indirect solar assistedheat pump systems with building-integrated combinedphotovoltaic thermal solar collectors (BiPVT) incold climates. Energy simulations of these systems showthat the system coefficient of performance (COP) canreach up to 5.6 for some selected configurations. Otherconfigurations can provide a high solar fraction and a bettercollector efficiency (up to 43%) at the expense of lowerCOP.A high COP and a better collector efficiency do not necessarilytranslate into a better investment because, factorslike buying and selling prices of the heat and the electricityequally important. The economic performance ofdifferent configurations in a dynamic multi-dimensionalcomparison suggests that the relatively simple systemwithout a heat pump can be a better overall choice for thecold climates.
