Özet
The Accumulated heat on the PV panels' upper surface could be dissipated by water circulation in the backside attached collector. This paper presents an experimental study to improve the performance of the PV/T system by modifying the collector design using a spherical bulge on the collector surface. The work was carried out at the University of Technology-Iraq. Two PV solar cells have been used in the experimental investigation. One is cooled by different water flow rates of 1.5, 2, 2.5, and 3.5 l/min; the other is a bare reference unit without any modification. The illustrated bludges are a matrix of spheres with a 25 mm radius arranged in 8 rows by 15 columns. The thermal efficiency of the PV/T increased by 8.08%, and electrical efficiency increased by 8.1% compared with the bare panel. Additionally, the impact of flow rate was discussed and evaluated in this study. Increased water flow rate decreased the PV surface temperature in the new model. With a flow rate of 3.5 l/m, the maximum surface temperature decrease was 15.4%. © School of Engineering, Taylor’s University.
