The flat single axis solar tracking system has one axis tracking the azimuth angle of the sun. Each set mounting 10 - 60 pieces of solar panels, single row type or 2 - rows linked type, given a 15% to 30% production gain over fixed-tilt systems on the same size array.

Currently, the flat single axis solar tracker in the market mainly features two solar array layout forms: 1P and 2P. The 1P layout scheme provides superior structural stability and excellent wind and snow pressure resistance, although it involves a higher amount of steel and more pile foundations. Another consideration is that its central main beam may cause more back shielding to bifacial solar modules compared to the 2P scheme.

The 2P scheme offers significant cost advantages. To ensure structural firmness for 500W+ and 600W+ large area solar modules, a double main beam structure has been developed. This design effectively supports the solar panels, prevents sagging at both ends, and reduces hidden cracks in the modules.
