RoofRay is a new website that uses Google Maps technology and mathematics to calculate the potential solar energy that could captured on a rooftop. RoofRay users locate a building using Google Maps satellite view then use RoofRay’s array drawing tool to highlight a section or all of a roof. After selecting an area users then select RoofRay’s estimating tools to calculate the potential solar energy that a roof could capture.

Below is a short video demonstration of RoofRay.

Applications for Education
RoofRay could be a useful tool for Earth Science teachers and Math teachers. Using RoofRay students can explore and estimate the potential solar energy of their school or neighborhood.
