Abstract :

Cooling panels using the half pipe method is one of the most important methods used to increase the efficiency of solar resources. In this article, a practical project for cooling a solar panel based on the half-pipe method has been carried out with the aim of increasing the efficiency of solar panels. In the proposed design, the half-pipes are installed directly on the bottom surface of the panel, and the available fluid, which is water in this technique, is inside the half-pipes and in direct contact with the panel, and performs the cooling process in a spiral on the surface of the panel. Two panels have been used to compare the performance of a panel equipped with a half pipe and a panel without this system, the panels have dimensions of 150 x 180 and power of 200 watts. Three sensors have been used to measure the temperature of the panels and the environment. The results show that using the half-pipe method can reduce the temperature of the panels by about 10 degrees Celsius. In addition, the results show a 36% increase in solar panel efficiency by using the half-pipe method.
