Numerical investigation of PV module cooling process by developing single-pass and doublepass PVT collectors

Abstract

In this study, single-pass and double-pass photovoltaic thermal collectors were designed and analyzed numerically. Energy efficiency and heat transfer coefficients of the PV module were calculated in the study. For case studies two different meteorological conditions (winter and summer) choosed. Case studies were performed with three different Reynolds number (15059, 17805, 22061). Avarage thermal efficiencies obtained for single and double-pass PV-T calculated in winter 65.15% and 67.88% ; summer 56.09%, and 58.46% conditions, respectively. For double- as PV-T, these values are It has been determined that the temperature of the PV module decreases with the increase in flow rate. Avarage electrical efficiency for single pass PVT in winter condition determined as 13.68% where for summer it was calculated as 13.24%. For double pass PVT these values obtained as 14.40% and 13.94%, respectively.
