Abstract
AbstractThis paper introduces a cooling system in a commercial photovoltaic panel using water to examine the improved output through a reduced operating temperature. It presents an alternative cooling technique for photovoltaic (PV) panels that include a water flow over panel surfaces. Solar radiation and operating temperature are two main parameters that affect the effectiveness of a photovoltaic panel. For these conditions, the electrical efficiency of the solar panel will be degraded as the operating temperature of the solar panel rises. Water flowed over the panel at a constant flow rate. The average temperature fall of the front and back surfaces is 3.54 °C and 2.79 °C, respectively, mainly the front water flow over the solar panel. Front cooling provides a 9.64% enhancement inefficiency on average. The average temperature fall of the front and back surfaces is 3.54 °C and 2.79 °C, respectively, mainly to front water flow over the solar panel.
