Normally, the solar panels are mounted on a fixed mounting structure. In such a case, the sun rays will be perpendicular on the panels during 12 noon. But, it is desired that they should be perpendicular throughout the day to ensure maximum energy generation. Hence, tracking systems are used and they are becoming popular day by day.
Single-axis, dual axis or manual tracking solutions are available. Single-axis trackers are most widely used. Up to 30% or even more extra energy can be obtained with the same set of solar PV array. Tracking systems are robust in construction and reliable technology.
