Understanding solar tracking systems for PV power plants

Solar module tracking systems

Solar module tracking systems are motorized mechanical racking systems that orient a solar array towards the sun. A tracker optimizes the angle at which panels receive solar radiation thereby maximizing electricity production of a solar plant. The angle at which the sun’s rays meet the surface of the solar panel determines how well the panel can convert the incoming light into electricity. This is known as the “angle of incidence”. The narrower the angle of incidence, the more energy a photovoltaic panel can produce. Solar trackers help to minimize this angle by working to orient panels so that light strikes perpendicular…
