Sun tracking by heliostats with arbitrary orientation of primary and secondary axes
Solar Energy, 2020 The tracking of heliostats with arbitrary orientation of the primary and secondary axes is considered, and the explicit formulas are derived to find the tracking angles for a given position of the sun.

For Brazil it is important to realize a high local production share because of high import tax rates. The rim drive concept offers an alternative for expensive heliostat drive solutions with slew and linear drives from abroad. By (locally produced) rims the demands on the drives regarding strength and precision are reduced to a very low value and low ...
