Back in 2015, Google launched a clever venture called Project Sunroof that used Google Maps data to assess the solar potential of individual roofs, giving homeowners a better idea of whether or not they should take the plunge. From humble beginnings in a few select cities the project has now expanded to cover every US State, and the data collected in the process makes a compelling case for solar indeed.
The upfront costs of installing rooftop solar might cause many to hesitate, particularly considering the unknowns around how much energy it would actually produce. Project Sunroof is Google’s attempt to remove some of the guesswork, combining aerial images from Google Maps with 3D modeling of the roof and even taking into account sun position, weather patterns and shade from nearby objects.
