Solar photovoltaic (PV) power plants utilize three main types of racking systems: ( i ) fixed tilt, (ii) single axis tracker, and (iii) dual axis tracker. A fixed tilt system positions the modules at a “fixed” tilt and orientation, while solar tracker systems automatically adjust the positions of the PV array so that the PV modules consistently “track” the sun throughout the day. Compared to a fixed tilt PV array, single or dual axis tracking systems will increase the energy production by 15 30% for the same size array.
