Dimensional Influences on the Response of a PV Tracking System

Abstract

Designing a bi-axial tracking linkage PV system relies on identifying the optimum dimensions to accomplish the Sun’s elevation and daily movements. To this effect, the dimensional variations are needed to be ranked according to their influence on the tracking response. Thereby the optimum adjusting possibility and the allowable tolerance for each dimension are set. To obtain these results the partial derivate method is approached. In practice, the element having the first-dimensional influence on tracking response is either provided with an adjustable system or is imposed with the highest dimensional precision. Herein, based on qualitative considerations, the second influencing length element is chosen to be adjusted.
