Zusammenfassung
Photovoltaic (PV) systems form an important force in the implementation of renewable energies, but as
we all know, the force has always its dark side. Besides efficiency considerations and discussions about
architectures of power distribution networks, environmental impacts caused by optical reflections are a serious
concern. PV systems generate optical reflections resulting in glare. On the one hand, glare is a serious
security concern, e.g. for traffic. On the other hand, glare is a constant source of discomfort in vicinities
of PV systems. Location-oriented assessments are required to limit potential reflections and to avoid
risks for public infrastructure and discomfort of residents. Hence, calculation of glare is decisive for the
success of renewable energies with respect to solar energy. Several courts ruled on necessary adjustments
of PV systems and even their de-installation because of glare effects. Our approach is to provide project
planners with a 3D-based simulation software to calculate and visualise reflections towards the environment
of PV systems. Hence, project planners receive flexible assistance for adjusting the parameters of solar
panels before installation of a PV system.
