Problem 3-2: Two-axis tracker data
The system is a heliostat with two-axis tracking: one vertical axis, and one horizontal (SN) axis. The goal is to determine the azimuth for the heliostat orientation and tilt angle for the horizontal axis at any time of the day in order to supply these data to the tracking system. A sketch of the collector is given below, and the blue line is the horizontal axis we want to tilt. The red line denotes the vertical axis, about which the collector can be rotated.
Calculate and tabulate a set of Zs-β data for every hour during the daylight period on March 21 at 40.7284° N, 75.1662° W. Feel free to use any available resources (SunChart diagrams or appropriate equations) to determine the position of the Sun at any hour. In this calculation, we can assume that incidence angle on the surface of the collector will be zero at any moment. Please provide references and explanations to your work.
