Performance study of a general azimuth-elevation heliostat tracking formula [PDF]
AIP Conference Proceedings, 2019 A single mirror heliostat with azimuth-elevation drive was installed in the 1MWe DAHAN solar tower power plant near Beijing. The heliostat mirror is a standard outer RP3 solar-trough mirror facet. The heliostat was configured for accurate measurement of tracking performance by using a single small flat reflector.
