What is a solar tracker and how does it work?

There are two main types of solar trackers available on the market: single- and dual-axis. Single-axis solar trackers track the sun east to west, rotating on a single point, moving either in unison, by panel row or by section. Dual-axis trackers rotate on both the X and Y axes, making panels track the sun directly.
