Technology firm Google is here with another innovative project. Have you been thinking whether installing solar panels on your rooftop is a good idea, what it could cost or save you? Based on the Google Maps data and 3D-models, project Sunroof calculates how well your rooftop is suited for photovoltaic panels. It takes into account shadows cast by nearby buildings and trees, brings in the positions of the sun over the course of the year and takes into account historical cloud and temperature patterns.
When your rooftop is the perfect place to install solar panels, it will be painted golden on the map, the less it is suited the more the colour shifts to deep purple. By providing your energy consumption data, the tool is able to compute your energy bill savings for various financing plans such as leasing, buying or taking a loan. It helps you connect with solar providers in the neighborhood if you’re convinced solar is the way to go.
Unfortunately, the tool only operates in a few locations at the moment: Boston, San Fransisco Bay Area and Fresno. The developer team is working on the expansion of the tool, but you probably need to have some patience before it becomes available at your hometown if you’re not living in the US. But after all, the project’s slogan goes Mapping the planet’s solar potential, one roof at a time. But for sure, the project will make the step to solar smaller again for everyone willing to make the shift to renewables.
