Where are the big roofs for Solar? A mathematical look at pulling data from OpenStreetMap

In recent years there has been a lot of talk about solar and more renewable energy. In USA the recent IRA has provisions for extending solar and renewable energy, and the Florida governor last year supported Solar benefits which turn out to be helpful in many natural disasters, making an energy grid more easily self-sustainable after hurricanes that are common to that state. What if we could go over a map and see what buildings are the best candidates for solar generation? OpenStreetMap has not just street maps, but many other features, including building coordinates, which can give us polygons that can calculate areas for potential solar!
