Google can calculate the solar electricity potential of your house

Date:19 August 2015

As the cost of solar panels has hit a record low in the USA, Google has unveiled a new project that aims to assist homeowners in calculating how much solar energy potential their roof has.

Called Project Sunroof, it uses Google’s mapping data to calculate how many hours of sunlight your roof is exposed to. It takes into account shadows cast by nearby structures, the position of the sun during the year and historical cloud and temperature patterns that might affect solar energy production. It also works out a solar plan to suit individual homeowners, while calculating their net savings and connecting them with solar panel providers.

Project Sunroof is currently only available in San Francisco, Fresno and Boston in the USA, but as Google is constantly expanding its investment in renewable energy – such as assisting the financing of the largest solar farm in Africa – we believe Project Sunroof will be coming to a suburb near you.
