Comparison of expected and measured values of luminance sensors in dual-axis photovoltaic positioning system

A dual-axis photovoltaic positioning system has a primary task of directing a PV module towards the optimal light source. The idea of positioning a loop requires proper information on the PV module direction in order to get more insolation, i.e. more energy. The assumption of a proper luminance sensor distribution and position is described in this paper. With this distribution every angle position is described by a unique combination of luminance sensor readings. This paper compares expected readings and measured readings of a real mechanical model.
