The Effects of Inclined Angle Modification and Diffuse Radiation on the Sun-Tracking Photovoltaic System

The photovoltaic (PV) system with an East-West sun tracker can obtain 10-35% additional radiant energy, compared with optimally tilted fully static arrays. The relationship between solar interarray spacing and the plus irradiance at different times obtained by sun tracking were studied and discussed. In three locations with different diffuse radiation ratios, the tracking efficiency of the East-We...
