Abstract
In this article, a solar-powered RO desalination system is investigated and simulated in detail. A solar PV panel with a negative temperature coefficient will have a lower efficiency as the temperature increases. The average photovoltaic (PV) solar panel has a conversion efficiency of 6-18 percent, which means that 84-96 percent of the energy that is produced is wasted. When recovering energy from solar PV panels, it is possible to collect more thermal energy than the electrical energy that the PV panels themselves supply. The heat was transferred from the panel's top and bottom by directly contacting moving water at both locations. PV panel performance and energy recovery were both increased via direct contact heat exchange from the panel's top surface. The incident radiation is made more straight when light is refracted by water. Increasing the angle of radiation and maintaining a cooler panel temperature both enhance solar efficiency. The CFD modeling of the temperature of PV panels matched the actual results. Large-scale solar photovoltaic (PV) systems are able to recover more energy. Therefore, the present research implies that the panel's performance may be improved by controlling its temperature and collecting thermal energy for use in other applications.
