Abstract

Sun is a great source of energy. Solar Energy is non-polluting and one of the most efficient and affordable energy alternatives available today. Solar energy can be utilised in two ways either in the form of thermal energy or electrical energy using photovoltaic (PV). The conversion efficiency of photovoltaic depends upon its operating temperature. The operating temperature of photovoltaic module is maintained as low as possible by withdrawing/utilizing the thermal energy associated with it. The thermal energy available on the PV module can be carried away by flowing any fluid (water, air etc.) above it. This type of system is known as hybrid photovoltaic thermal (PVT) system. In the present study, the analytical expressions for temperature dependent electrical efficiency have been derived for opaque and semitransparent PV module with water flow. Then comparison between efficiencies have been done for different climatic condition of New Delhi, India. Then it is observed that there is remarkable change in efficiency when water is flow on the top of the surface of PV module.

水流对光伏组件的影响:一个案例研究

太阳是一种重要的能源。太阳能是无污染的，是当今最有效、最经济的替代能源之一。太阳能可以以两种方式利用，要么以热能的形式，要么利用光伏(PV)的电能。光伏的转换效率取决于其工作温度。光伏组件通过回收/利用与之相关的热能来保持尽可能低的工作温度。光伏组件上可用的热能可以通过在其上方流动的任何流体(水、空气等)带走。这种类型的系统被称为混合光伏热(PVT)系统。在本研究中，推导了不透明和半透明有水流的光伏组件的温度相关电效率的解析表达式。并对印度新德里不同气候条件下的效率进行了比较。然后观察到，当水在光伏组件表面顶部流动时，效率有显著的变化。
