Range of motion study for two different sun-tracking methods in the application of heliostat field

► Study on the range of motion for two different sun-tracking methods at the level of single heliostat and heliostat field has been carried out. ► The algorithms to analyze the annual accumulated sun-tracking angles for both methods have also been developed. ► The annual accumulated elevation angle for the SE method is around 46% of the annual accumulated elevation angle for the AE method. ► The annual accumulated azimuth angle for the AE method is about 26% to 29% of the annual accumulated spinning angle for the SE method. ► In the level of heliostat field, SE method consumes about 4.8% to 9.3% lesser power on the sun-tracking system than that of AE method.
