4.1 Solar thermal power plants

Abstract

This chapter talks about solar power and solar thermal power plants. It describes different options for conversion of solar irradiance reaching the Earth into electricity for human applications. The direct conversion of the solar photons into electricity can be performed by using semiconducting materials in photovoltaic cells. Basics of photovoltaic technology, solar radiation and related optics are presented. The radiation transfer model is shown. Energy yield is higher if the direct normal irradiance energy is collected instead of the global horizontal irradiance on a location with good yearly irradiance. The main designs that have found applications in concentrating solar technology would need a detailed optical analysis for deducing performance and flux density distributions in the focal planes or volumes. A solar thermal power plant uses the energy of the sunlight, converts it into heat and then into electricity by means of a thermodynamic process. The receiver is the component that has to convert the sunlight into heat delivered to transfer medium. Various receivers have been discussed. A new process based on dual medium concept is to use sand/air as heat transfer fluid and storage material. Comparison of various solar thermal power plants is also presented.
