interconnected tubes. During the high radiation hours, most of this energy is directly
transferred to the power system, and the remaining energy is accumulated in the stor-
age (for utilization during low radiation hours). Energy transference to the power cy-
cle is accomplished through a heat exchanger located before the turbine inlet.
The main parameters considered in the simulation are shown in Table 12.6.To
calculate the required area for the parabolic cylindrical solar collector to satisfy
the complementary heat requirements, the basic parameter to be considered is the
thermal efficiency of the solar collector.
The thermal efficiency, “h,” of a PTC is the captured or gained useful energy
divided by the incident radiation on the aperture plane, as shown in Eq. (12.1). 23
