Abstract

Solar photovoltaics (PV) on building rooftops is a major contributor to the decarbonization of energy systems and provides electricity close to consumption. However, high shares of PV challenge distribution grids and require energy storages due to the fluctuating daily and seasonal production profile. We calculate storage requirements for integrating electricity from rooftop PV into urban energy systems using a case study of the Hanover Region in Germany. The storage requirements change with the level of PV deployment. Aggregating production and consumption of the Hanover Regions we find that storage is not required until 44% of the maximum realizable PV capacity potential is deployed. This is because hourly PV production never exceeds the hourly load. At 100% of the realizable PV capacity, the region achieves a solar coverage of 37% and supplies an additional 19% of its annual consumption from PV using appropriate urban storages. This holds without considering any wind energy. A high-resolution spatial analysis shows that areas with high population density have significant balancing needs, as they exhibit high residual load and residual production, while being net consumers in the annual balance. In contrast, rural regions become net producers. Our results can support the planning of efficient energy storage systems and backup power plant capacities.
