This project combines ultra-high-resolution (0.5 meter or 1 meter) Digital Elevation Model (DEM) data and 3D vector building footprint data with [satellite-derived] solar irradiation data and uses accurate anisotropic irradiance transposition and power simulation along with detailed shading estimations to provide gridded PV generation timeseries for all buildings in a growing list of cities worldwide. This is an ongoing collaboration with the International Renewable Energy Agency (IRENA) for the development of the SolarCity simulator, which is a web application that enables households, businesses and municipal authorities to assess the technical and economic prospects of electricity generation using rooftop solar PV.
