TL;DR: In this article, a reference solar thermal and air source heat pump combisystem was defined and modelled based on products available on the market and a singular economic cash flow analysis was carried out and the "additional investment limit" of each system variation was determined for a range of economic boundary conditions.

TL;DR: In this article, a comparison of solar thermal and heat pump combisystems for domestic hot water and space heating in dwellings is presented, and a comparison is made with a comparison between the two systems.

TL;DR: In this article, different combinations of solar energy and heat pump systems are compared and investigated through transient system simulations, and serial solutions for the combination of solar-HP systems are defined and analyzed.

TL;DR: A suitable disturbance-prediction, which approximates the expected solar energy flux into the storage, in connection with a linear model predictive control (MPC), can prevent the auxiliary system to switch on at an early stage and thus reduce the auxiliary energy demand and keep storage capacity for solar thermal energy supply.

TL;DR: In this article, the authors presented results from the national Austrian project "Highly efficient combinations of solar thermal and heat pump systems (SolPumpEff)", where the authors considered different combination of solar energy and HP systems through dynamic system simulations in TRNSYS.
