Construction and implementation of a cooling system to increase the efficiency of photovoltaic panels using the half pipe method

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.
