6 FAQs about [Efficiency of solar thermal power generation]

Are solar thermal applications better than solar PV?

While solar PV power generation has gained rapid momentum and is highly efficient for power generation, solar thermal applications, including both CSP and direct solar heat applications, offer a range of advantages for addressing specific energy needs in industrial, agricultural, residential, and commercial sectors.

What are the efficiencies of a solar-to-electricity power plant (STPP)?

In this type of STPPs, solar-to-electricity efficiencies are around 25%, since the power block is limited and its thermal performance is in a range between 35% and 38% and the solar field efficiency is around 65%.

How can solar thermal components reduce the cost of electricity generation?

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.

How to choose a solar thermal power plant?

Solar thermal power plants for electricity production include, at least, two main systems: the solar field and the power block. Regarding this last one, the particular thermodynamic cycle layout and the working fluid employed, have a decisive influence in the plant performance. In turn, this selection depends on the solar technology employed.

How do solar thermal power plants work?

Solar thermal power plants are composed of three processes: collection and conversion of solar radiation into heat, conversion of heat to electricity, and thermal energy storage to mitigate the transient effects of solar radiation on the performance of the system.

Does solar irradiance affect thermal efficiency?

The results showed that the thermal efficiency increased at higher solar irradiance, as expected, but also that the thermal efficiency of the collectors decreased during the afternoon when the water temperature was high compared to the condensation temperature of the heat pipe.
