“…These collectors generally do not have solar tracking and are set at fixed tilt and orientation angles that maximize their annual energy production [32,44]. The foremost non-concentrating collectors are the flat plate collector (FPC), evacuated tube collector (ETC), and stationary compound parabolic collector (CPC) [47]. On the other hand, concentrating collectors reflect the beam radiation incident on a reflective surface onto a smaller collecting surface [17,48].…”

“…The most common concentrating collectors with one-axis tracking are linear Fresnel collectors (LFC) and parabolic trough collectors (PTC). With two-axis tracking, the most common are the parabolic dish concentrator (PDC), and heliostat field reflector (HFR) [20,47,49]. The common CR and temperature ranges of ST collectors are shown in Figure 2.…”

“…The efficiency of ST collector is affected by the optical and thermal losses (Figure 3) [47]. The optical losses are due to the geometrical and optical (reflectivity, absorptivity and transmissivity) parameters of the collector.…”

“…The optical losses are due to the geometrical and optical (reflectivity, absorptivity and transmissivity) parameters of the collector. Thermal losses are due to heat transfer by conduction, convection, and radiation from the collector to the environment, and depend on the temperature difference between the components of the ST collector and its surroundings [47,50,51]. As is shown in Figure 4, FPCs have higher optical efficiency than other collectors but are also more affected by thermal losses.…”

Process heating is the activity with the most energy consumption in the industrial sector. Solar heating (SH) systems are a promising alternative to provide renewable thermal energy to industrial processes. However, factors such as high investment costs and area limitations in industrial facilities hinder their utilization; therefore, hybrid systems that combine two different solar thermal or photovoltaic technologies where each technology operates under conditions that allow a higher overall performance than conventional configurations have been proposed. In this review, we discuss the limitations of conventional SH systems and the potential of hybrid configurations to overcome them. First, the current literature about conventional and hybrid systems is presented. Then, the application of common performance indicators to evaluate hybrid configurations is analyzed. Finally, the limitation, advantages, and potential applications of conventional and hybrid systems are discussed. This work shows that conventional systems are the most promising alternatives in low and high-temperature industrial applications. At the same time, in medium and processes, hybrid configurations have great potential to increase the performance of SH systems and help to boost their adoption in the industrial sector. There are few studies about hybrid systems in industrial applications, and further research is required to determine their potential.
