Performance investigation of photovoltaic cells with evaporative cooling

The increasing global demand for energy and the sharp increase in the prices of oil derivatives accelerated the work in developing renewable sources of energy to be promising in the construction of an energy sustainable and environment-friendly economy. Exploiting solar energy for domestic use is one avenue where the energy emitted from the sun is converted into electricity to power most, if not all, of the appliances available in our homes and residences. Therefore, solar energy is so necessary for appropriate climatic conditions in the country. The need for electric power because of the current situation. Fabricating a photovoltaic system is the process of designing, selecting, and calculating the ratings of the equipment’s employed in the system. This process depends on various factors such as geographical location, solar irradiation, and load requirements. Installing solar photovoltaic systems in places facing the sun’s rays to obtain the largest solar radiation. However, the high temperature of the surfaces of these systems, especially in hot areas, has a negative impact on the performance of these systems. This is the main problem in reducing the performance of the systems. A hybrid cooling system is fabricated to increase the conversion efficiency of the solar panels by using the water-air heat exchanger. The load was estimated for a residential house in the Al-Sharqat district. Then the P.V. system components are selected. The evaporative cooling system was manufactured to cool the panel. All tests were conducted in Feb, March, and April 2022, and the results showed an improvement in the performance of cells by 35%. This study presents a practical way to calculate the elements and components of the P.V. energy system and procedure an economic analysis for the system components. This depends on the efficiency of the Inverter, solar power panels, and capacity of batteries in the local market, taking into account the climatic conditions and hours of solar radiation in the system installation area and the cost of the system the payback time.
