Harnessing solar energy for electric power generation is one of the growing technologies which provide a sustainable solution to the severe environmental issues such as climate change, global warming, and pollution. This chapter deals with the solar thermal power generation based on the line and point focussing solar concentrators.
The utilization of solar energy for heat and power generation has recently attracted increased interest as is evident from the significant number of research publications in the last 4–5 years.
The PV technology convert visible spectrum to electricity and thermal collectors use both infrared and visible spectrum for energy generation. So the energy generation from solar radiation can be in the form of electrical energy or thermal Energy. The various conversion paths of solar energy is described in the Fig.2
To compare the different solar thermal power generation systems, some key characteristics/parameters are important to analyze the performance of the power generation system. Some of those parameters are discussed as follows: Aperture is the plane of entrance for the solar radiation incident on the concentrator.
Solar radiation is one potential abundant and eco-friendly heat source for this application, where one side of the thermoelectric device is heated by incident sunlight, while the other side is kept at a cooler temperature. This is known as solar thermoelectric generation.
It is important for the solar energy based heat and power plants to follow the dynamic characteristics of the consumer load profiles for reliably satisfying the end-user demands. Solar-only technologies have been found to be incapable of doing so. Some form of hybridization, storage, or backup is necessary.
