Savanna™ Trackers Time-lapse - The Savanna™ dual-axis PV Tracker is a low cost solar PV tracker, with very low costs to install and operate. In this video, trackers are seen tracking the sun throughout the day, which increases performance by 25-40%, when compared with fixed panels. The Savanna™ employs a unique, proprietary back-tracking algorithm to minimize shading when tracking. The back-tracking algorithm changes the panels' elevation angle according to the sun's position to avoid shading the panels behind it. Although the algorithm will move the panel away from the being perpendicular to the sun, the total power production is greater than when there are partially shaded panels.
