Description
Summary:At the peak of the solar radiation, the efficiency of the photovoltaic module and the energy output decrease due to the high temperature of the PV panel, which leads to the loss of energy produced by the photovoltaic panels. The present research includes a study to increase the efficiency of the photovoltaic unit by hybrid cooling using fins and water flow together. The PV module is cooled by naturally flowing air over the surface of the fins installed beneath the back surface of the photovoltaic panel, and water flows over the PV panel surface at 1, 2, 3, and 4 liters per minute. The experiments were conducted with three 50W solar panels installed on the roof of a steel structure one meter high to provide space for cooling air. The back of each of two panels was connected to the aluminum heat sink and the distribution is located in the PV1 staggered and PV2 in-line. These two panels were tested with hybrid cooling, while the third PV0 was installed without cooling. This article presents an experimental investigation according to the meteorological conditions of the city of Babylon, Iraq. The results indicate that the cooling of inline arrangement PV2 is better than that of staggered one PV1 in the two cases of presence and absence of water. The average temperature of the PV2 was reduced to 22°C, 18°C, 15.6°C, and 18.5°C with a flow rate of 1,2,3, and 4 l/m, respectively. Consequently, the electrical efficiency was improved from 11.5% to 12.3%, 13.3%, and 12%, at flow rates of 1, 2, 3, and 4 l/m, respectively.
