Abstract
The research included a practical and theoretical study on a PV/T collector to verify the validity of the results and data provided by the simulation program used in the research (TRNSYS). A practical PV/T collector was designed and implemented, followed by theoretical simulation using the (TRNSYS) program. Comparitive analyses of the practical and theoretical results of both closed cycle and open cycle systems was conducted under the atmospheric conditions of the Mosul, Iraq. The solar collector was faced the south, and comprehensive data form the practical setup were recorded after its operation. For the closed cycle, the results showed an error of 2.7% in the exit water temperatures from the solar collector and a 3.4% error in the tank water temperature. In the open cycle, an error of 2.8% was recorded the incident radiation intensity, with 3% error in the solar collector’s thermal efficiency. The close difference of these results confirms the accuracy of the data provided by the TRNSYS program, indicating its reliability for developing and studying other theoretical systems, thereby saving time, effort and money
