Dear TRNSYS users, we developed and published a new user-written TRNSYS component Type 835: PV model for the coupling with solar thermal absorber and collector models as PVT model (free download link below). The main idea behind this model was to develop a PV performance model in TRNSYS, which can be coupled to existing models of solar thermal collectors or absorbers for the calculation of the electrical power output of WISC and covered photovoltaic-thermal (PVT) collectors. It is especially developed for the connection with thermal models which are based on the quasi-dynamic model of ISO 9806, e.g. TRNSYS Type 832 (Haller et al., 2013), and is validated for this combination. As addition, the model includes a PV mode to simulate PV modules based on the same performance model, e.g. for a comparison of the electrical yield of a PV module and PVT collectors using identical PV cells. The major difference between the calculation of PV modules and PVT collectors in this approach results from the cell temperatures, which are determined by the fluid temperature in PVT collectors and by a steady-state module temperature in PV modules. The model is available for free and the latest release version can be downloaded from: https://www.doi.org/10.5281/zenodo.1446414 GitHub repository: https://github.com/DnJns/TRNSYS_Type835_PVT Furthermore, a paper on the implementation, validation and parameter identification approach for the PVT performance model using TRNSYS is published in Solar Energy Journal with Open Access: https://www.sciencedirect.com/science/article/pii/S0038092X19309223 We hope it helps the community for new investigations on PVT technologies and its application in energy systems.
