Solar systems, particularly hybrid Photovoltaic-Thermal (PVT) systems that generate both electric and thermal power can potentially cover significant part of heating and cooling demand of buildings. To evaluate the integration of PVT collectors to building energy system operation, dynamic system simulations are commonly carried out to evaluate the performance. So far, simulation of performance has focused mostly on liquid-based variants. However, for simulation of air-based PVT systems, implementations are limited and usually highly customized. In this investigation, the aim is to simplify such simulations, through already existing components found in the widely used simulation environment, i.e., TRNSYS. To achieve this, long term operation measurements of an Air-Based PVT prototype are used to validate a dynamic simulation system model. Additionally, former Computer Fluid Dynamics analysis aids in identifying key operational and heat transfer parameters. Furthermore, aspects regarding different configurations of Air-Based PVT integration to HVAC are discussed in detail.
