Orientation of strings

The orientation of the strings can be fixed or variable for the presence of a solar tracker. BlueSol allows you to specify on each string, the type of orientation, which can be:

• Fixed inclined plane: The string is in a fixed position and angles of Tilt and Azimuth cannot never change.

• Two-axis tracker: Two axis trackers have two degrees of freedom that act as axes of rotation, this solution allow for optimum solar energy levels due to their ability to follow the sun vertically and horizontally. Therefore the angles of Tilt and Azimuth vary according to the position of the sun and the sun's rays are always perpendicular to the surface of the modules.

• Single-axis vertical tracker: The axis of rotation for vertical single axis trackers is vertical with respect to the ground. These trackers rotate from East to West over the course of the day, the angle of Tilt is fixed and the Azimuth angle varies. The tracker will change the angle of azimuth in order to minimize the angle of incidence between the sun's rays and the plane of the modules.

• Single-axis horizontal tracker: The axis of rotation for horizontal single axis tracker is horizontal with respect to the ground. In this case the angle of Azimuth is fixed and varies the angle of Tilt. The tracker will change the angle of tilt in order to minimize the angle of incidence between the sun's rays and the plane of the modules.

The Tracker configuration allows you to set the maximum and minimum limits of the angles that the tracker may vary.

Note that the angles of tilt and azimuth assigned to strings (and used in the drawing of the layout), they are still used by the program. In the single-axis trackers is the angle remains fixed, the software also assumes that the string takes this orientation before sunrise and after sunset when there is no sun to govern the movement of the tracker.
