DETERMINING OF REFLECTION AND GLARE CAUSED BY REFLECTED SUNLIGHT ON PV MODULES SURFACES AT PV SYSTEMS

摘要

The specially developed software calculates for a specific l°Cation the reflections of photovoltaicsystems with a particular fix mounted orientation and displays them graphically for all directions and for all daysduring a whole year. The sun's position and the reflected rays of the sun can be presented both in Polar and Cartesiancoordinates to detect intersections with the position of objects in the neighborhood. Another graph shows the durationof the reflected radiation within a year. So it can be determined how long in a certain range, reflections of aphotovoltaic system °Ccur and if given limits are exceeded. For these calculations the height profile of the hazard areacan be imported to facilitate the detection of precise glare times.
