  While photovoltaic (PV) systems are installed at an unprecedented rate,
reliable information on an installation level remains scarce. As a result,
automatically created PV registries are a timely contribution to optimize grid
planning and operations. This paper demonstrates how aerial imagery and
three-dimensional building data can be combined to create an address-level PV
registry, specifying area, tilt, and orientation angles. We demonstrate the
benefits of this approach for PV capacity estimation. In addition, this work
presents, for the first time, a comparison between automated and
officially-created PV registries. Our results indicate that our enriched
automated registry proves to be useful to validate, update, and complement
official registries.
