Determination of global radiation capture percentages using PV LIGHTHOUSE in two photovoltaic installations, one fixed and one mobile

Abstract

The PV LIGHTHOUSE Solar Radiation Spectrum Calculator determines the spectrum of solar radiation intercepted by a photovoltaic
module under clear sky conditions, where the user sets; the location (Latitude and Longitude), module orientation (tilt angle and azimuth angle), time, day and month of the year and atmospheric conditions for clear skies. The calculator then determines the direct, diffuse, and their sum components of the spectral radiation incident on the module. The calculation for the two installations has been made for the 4 days of the year in which each season begins, namely; Equinoxes, summer and winter solstices and for each hour in a time range from 6 a.m. to 6 p.m., where it was determined that the two-axis mobile installation with a single motor and gear-pivot mechanism captures 35% more global radiation than the fixed installation.
