What are the algorithms for single-axis-horizontal solar trackers with monofacial PV modules?

This article presents the fundamentals of four algorithms for single-axis-horizontal solar trackers with monofacial PV modules. These are identified as the conventional Astronomical tracking algorithm, the Diffuse Radiation algorithm, the Diffuse + Nowcasting algorithm, and a completely new algorithm called Analytical.

What is horizontal single axis solar tracking system with astronomical tracking algorithm?

Horizontal single-axis solar tracking systems with Astronomical tracking algorithm are commonly used in photovoltaic (PV) installations. However, different algorithms can increase the PV installation's performance without implementing new equipment or technologies.

Which solar tracking algorithms have higher PV output values?

Solar tracking algorithms with the BT strategy have higher PV output values than the same tracking algorithms without the BT strategy. This advantage depends not only on the solar tracking algorithms and the location (ratio of direct radiation and diffuse radiation), but also on the PV modules mounting configuration.

Why are two-axis solar tracking systems important?

For this reason, two-axis solar tracking systems allowing the optimal perpendicular position of the plane of array (POA) to the solar vector were the predominant ones, as they also enabled an increase in the annual energy production of more than 30% compared to a fixed PV installation.

Do shaded PV modules affect power output?

Therefore, depending on the orientation of the PV module—portrait (vertical) or landscape (horizontal)—the power output losses derived from the same percentage of module area being affected, even if the shaded area is relatively small, could differ substantially.
