The growing amount of photovoltaic systems in urban environments creates peaks of energy generation in local energy grids. These peaks can lead to unwanted instability in the electrical grid. By aligning solar panels differently, spikes could be avoided. Planning locations for solar panels in urban environments is very time-intense as they require a high spatial and temporal resolution. The aim...
