Abstract: An Unmanned Aerial Vehicle (UAV), method, apparatus, and computer-readable medium for solar site assessment includes generating a three-dimensional model of a solar site based at least in part on data captured by an Unmanned Aerial Vehicle (UAV), importing one or more solar paths into the three-dimensional model based at least in part on a geo-location of the solar site, and determining, one or more solar collection estimates corresponding to one or more locations in the solar site based at least in part on the three-dimensional model and the one or more solar paths.
