Among the solar technologies under consideration, concentrating
solar technologies (CSP) have the greatest potential for
commercial electrical power generation and they have successfully
demonstrated their capability of producing high-temperature
steam to power the conventional Rankine cycle for electricity
eneration [4,6,7]. These technologies are based on collectors which
concentrate the sun’s heat energy to produce steam for driving
electrical generators [8]. The main technologies used in CSP plants
are the parabolic trough collectors, Fresnel mirrors, dishes and
finally power towers [9–12]. Of these technologies, the parabolic
trough and the solar tower technologies have reached the commercial
stage [13].
