【 摘 要 】

Solar photovoltaic cells produce electricity by receiving solar radiation. The output power of photovoltaic cells (PV) is mainly influenced by the significant increase in cell temperature during the absorption of radiation. The solar cooling system has been considered and investigated experimentally in this research paper. A passive cooling system was designed and fabricated for efficiently cool the PV module, with inlet/outlet manifold considered for uniform flow of water at the rear side of the PV module. The experimentation was performed with and without the cooling system. In this paper, a linear trend has been established between the electrical efficiency and the temperature of the photovoltaic cells. Without a cooling system, the average cell temperature reaches to 600C, and the solar panel efficiency reduced to 8 to 16%. However, when the panel was operated under the passive water system, the temperature of the PV cell was reduced to 47°C, resulting in a 10% -21% improve in the solar PV cell efficiency. Both systems, without cooling and with cooling systems are validated experimentally.
