What is a Sun NumberTM Score?
A Sun Number score represents the solar suitability of a building’s rooftop on a scale from 1 to 100, with 100 being the ideal rooftop for solar. Scores can be accessed by entering a valid address in a region where the analysis has been completed. The Sun Number score is created from aerial imagery that is processed with proprietary algorithms to accurately analyze individual rooftops.
