In this paper, the mathematical models of a solar thermal system which governs the solar thermal collector, the heat storage system, and the pump are presented. It has been shown that it is possible to connect a Simulink-based model to a meteorological database server using standard communication protocols by a C language-based component in order to import real-life weather information into the simulation. The setup of the model predictive control of this solar thermal system and the results of the simulation are also presented. This computationally heavy control method is possible to use on today's personal computers, and it can be expanded.
