As of early 2016, the average solar cell is only 15% efficient [9]. All solar panels have a maximum power point (MPP), which is the optimal conditions where they produce the most electricity. It's significantly less than the maximum available output (210 watts) of the module. The motive behind solar tracking is to maximize the output from solar panels by aligning the solar array towards the sun in such a way that the angle of incidence (the angle from which the sunlight falls on the panel is the minimum). Additionally, it can be applied to use with more energy sources. Let us understand solar cell working principle. A solar tracker is a device that orients a payload toward the Sun.
