Abstract: This paper evaluates configurations of indirect solar assisted heat pump systems with building-integrated combined photovoltaic thermal solar collectors (BiPVT) in cold climates. Energy simulations of these systems show that the system coefficient of performance (COP) can reach up to 5.6 for some selected configurations. Other configurations can provide a high solar fraction and a better collector efficiency (up to 43%) at the expense of lower COP. A high COP and a better collector efficiency do not necessarily translate into a better investment because, factors like buying and selling prices of the heat and the electricity equally important. The economic performance of different configurations in a dynamic multi-dimensional comparison suggests that the relatively simple system without a heat pump can be a better overall choice for the cold climates.
