Solar Mapping Results In More Highways

Based in Atlanta, the Ray is a nonprofit that sets ambitious environmental goals. Primarily, it aims to build net-zero highways, beginning with an 18-mile stretch of Interstate-85 located in west Georgia. One of the ways it plans on doing so is with right-of-way solar panels, a means of generating solar power that is built upon right-of-way land (areas of land managed by State departments of transportation and are essentially under public ownership).
However, before construction can even begin, usable land areas need to be identified. For this to happen, the Ray utilizes a solar mapping tool provided by Esri. The tool identifies right-of-way areas that are most suitable for development, taking into consideration factors such as erosion, sunlight, and elevation.
The solar mapping tool not only allows the Ray to expand their search for possible right-of-way locations throughout the entire country, but also aids in predicting potential impacts of construction. Using the analysis provided by the tool, the Ray is able to simulate various structural plans for the solar panels; this then allows the organization to implement the plan with the lowest impact on surrounding communities.
GIS software has also helped quantify the amount of solar power certain land is able to generate. While working with the state of Iowa, The Ray was able to find that the 38,000 acres of possible land would be able to produce 5 million megawatts generated per hour, per year. In terms of money, this energy would be worth around $400 million.
