In order for a Solar 18 to be the most efficient, the lens must be pointed directly at the sun. This requires a tracking system, which is adjusted and set up at every single location, using both the altitude and azimuth. Solar 18's design of follow the sun modules includes an integrated two-axis tracker and positioning system. Each module contains a motor that tracks the sun's altitude and the azimuth. Tracking is set up once, depending on geographic location and relies solely on internal technology to find and track the sun.
