Google. For GSS Energy Use chapter 10. Excerpt:  Project Sunroof puts Google's expansive data in mapping and computing resources to use, helping calculate the best solar plan. ...When you enter your address, Project Sunroof looks up your home in Google Maps and combines that information with other databases to create your personalized roof analysis. ...Project Sunroof computes how much sunlight hits your roof in a year. It takes into account: Google's database of aerial imagery and maps; 3D modeling of your roof; Shadows cast by nearby structures and trees; All possible sun positions over the course of a year; Historical cloud and temperature patterns that might affect solar energy production. ...Project Sunroof recommends an installation size to generate close to 100% of your electricity use, based on roof size, the amount of sun hitting the roof, and your electricity bill. ...We recommend an installation that covers less than 100% of your electrical usage because, in most areas, there is little financial benefit to producing more power than you can consume. ...Project Sunroof uses current solar industry pricing data to run the numbers on leasing, taking a loan, or buying solar panels for your house to help you choose what's best for you. ...Project Sunroof also compiles the following incentives to calculate your final cost: Federal and state tax credits; Utility rebates; Renewable energy credits and net metering.... https://www.google.com/get/sunroof/about/
