Computer Modelling and Experimental Validation of a Photovoltaic Thermal (PV/T) Water Based Collector System

A photovoltaic thermal water based collector system is modeled by TRNSYS as a numerical model and the results validated with experimental results in this paper. The validity of the modeling approach was demonstrated by comparing its predicted collector's outlet temperature changes and daily system efficiencies with the measured data acquired from an experimental rig at Ferdowsi University of Mashhad. The main component of the TRNSYS deck file constructed for this purpose is type 50a, which is accompanied by other additional components required for the model. The predictions from the model show good compliance in outlet collector fluid temperature and system's thermal and electrical outputs with the experimental measurements. The main aim of this paper is find a good simulation for a PV/T system.
