Abstract

In this work, experimental and numerical analyses have been executed to investigate the effect of using cooling techniques on the performance of the photovoltaic thermal solar panel (PV/T). It is well known that a decrease in the panel temperature will lead to an increase in the electrical efficiency. The photovoltaic/thermal (PV/T) collector is a combination of PV cells and a solar thermal collector in one unit, which can together generate electrical and thermal energy. In the theoretical study, the electrical characteristics of PV were analyzed by using (MATLAB PROGRAM). The panels were oriented south and tilted at 45^o. All tests are carried out in Baghdad city at (May, June and July) in 2018; under clear sky conditions. The experimental study includes four cases (modules). Module I contains open cell aluminum metal located in water passages box of a 9-liter capacity in the back of PV panel. Module II contains only water pass. Module III comprises copper slices that are located in the water box. The first three cases are compared with the conventional PV panel under the same conditions. compares between the PV with open cell aluminum metal and the other PV with copper slices. The results manifested that the cooling of PV panel in the module III is better than the others, but economically, the use of module I is the best, therefor it is found a more acceptable technique for hot climate conditions
