Influence of Terrain on Single-Axis PV Plants
Abstract
This paper presents a systematic study of the influence on the radiation capture of the azimuth angle of horizontal one-axis as well as the inclination and azimuth of the terrain where they are built. The results prove that, to optimize the radiation capture and, consequently, the energy production, for South facing terrains, the tracker rotation axis must be also oriented to the south for any terrain inclination. However, for not south facing terrains, the rotation axis azimuth of solar trackers should be deviated from the South in the same direction as the terrain azimuth.
