Project Overview

"Aurora Solar developed advanced measurement tools that utilizes Google Street View as a basis for remotely measuring roof slope, roof edge lengths, and other distances. These measurements are the inputs into a three-dimensional model, which is used to calculate the aforementioned irradiance and solar access values." (NREL)

Reported Results

Proof of concept: a blindy study was conducted and determined Aurora's remote measurement tools yielded results found to be within their stated accuracy bounds 98% of the time.

Technology

According to Aurora: "Aurora Envision’s 3D Metric Estimation tool uses any satellite or aerial imagery (such as Google, Bing or even aerial imagery captured from a drone) and Google Street View imagery to provide those two different viewpoints needed to use triangulation. These images also provide information on the camera position that is accurate within a few feet. With this data, computer vision allows project designers to extract 3D measurements from the scene—such as the slope of a roof or the heights of chimneys or trees—ensuring the accuracy of the site model."

Background

From the NREL: "As part of the U.S. Department of Energy (DOE) SunShot Incubator program, Aurora Solar has developed a web-based application that quickly and precisely calculates the solar potential of a roof. The results of this application will increase the ability of solar firms to accurately assess large numbers of potential solar installation sites and increase closing rates."
