Google project Sunroof is the way of find How Well Solar Would Work On Your House Roof Top.
Venture Sunroof utilizes data that is as a part of Google Maps to make sense of the amount of sun falls on a rooftop and considers stuff like the edge of the rooftop, the climate, and blocks like trees and fireplaces. At that point it utilizes those estimations to make sense of what number of boards you’d presumably require and the amount you could save money on your electric bill, incorporating sunlight based motivations in your general vicinity. You can perceive how purchasing or renting boards influences your investment funds, and after that send your appraisal to installers in your general vicinity, right away.
Unfortunately, this as of now just works in the San Francisco Bay Area, Fresno and Boston.
