Thethermodynamic cycles used for solar thermal power generation be broadly can classified as low, medium andhigh temperature cycles. Low temperature cycles work at maximum temperatures of about 100°C, medium temperature cycles work at maximum temperatures up to 400°C, while high temperature cycles work at empera- tures above 400°C.
Cell temperature of the photovoltaic modules is estimated with various known models in the literature. Based on the estimated cell temperature and global solar radiation values on inclined surface, power generation values of the on-grid and off-grid systems are forecasted.
Hence, the electricity generation by solar thermal technologies involves the collection and concentration of solar radiation in the form of heat and its conversion into electricity. The limitation of solar power generation technologies is the diurnal (day and night) and intermittent (hourly, daily, and seasonal) nature of solar radiation.
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.
Advancements in the design of the solar thermal components improve the performance and consequently reduce the cost of electricity generation. This chapter discusses all the available CSP technologies and highlights the various design and operational parameters on which the overall efficiency of the solar power plants depends.
Furthermore, module temperature and PV cell material bandgap energy are closely related, with bandgap energy typically decreasing at high operating temperature. PV modules are characterized temperature coefficients which measure the change in operating performance per degree Kelvin (or Celsius) rise.
