Solar concentrating collectors are special types of thermal collectors that convert the solar radiation energy to the internal energy of the heat transfer fluid (such as water, oil, or air) in the collectors.

A concentrating collector system consists of one or more solar concentrators and receivers ( Fig. 1 ). Solar concentrators capture natural solar radiation and increase the magnitude of the solar flux while directing it onto the aperture of a solar receiver or receiver–reactor.
It could be noted through the literature that concentrating collector systems could have a storage component that enables the solar collector to use the absorbed heat by the concentrator at night time and increases the performance, namely thermal and electrical efficiencies as well as plant's production rate.
Adolfo Palombo, in Solar Hydrogen Production, 2019 The concentrating collectors can absorb the sun radiation and convert it to thermal energy by interposing an optical device between the radiation source and the energy-absorbing surface. A sketch of concentrating solar thermal collector concept is depicted in Fig. 6.10.
They found that the combination case is the best case with 0.82% thermal efficiency enhancement when the use of fins leads to 0.62% and the use of nanofluids to 0.26%. Solar dish concentrators are concentrating collectors under developments, and different ideas are applied to them.
By Eq. (6.29) it is possible to justify the high temperatures reached through the concentrating solar collectors. Here, in fact, the higher the concentration ratio (C), the lower the thermal losses (obtaining thermal efficiencies approaching the optical ones). The LFCs, similarly to PTCs, are one-axis concentrating solar thermal devices.
