Deployment of rooftop solar PV systems across a 5.4-square mile area of Cleveland could produce more than 100 GWh of emissions-free electricity per year, enough to power some 10,000 average homes, according to NASA researchers.
The NASA research team used a variety of innovative remote sensing and GIS tools to assess rooftop solar energy potential of an area that included both residential and industrial buildings, some in the downtown Cleveland area, according to an industry news report.
The solar energy potential of one-fifth of the 560 buildings assessed accounted for 85% of the prospective generation capacity. Nearly two-thirds of them were categorized as industrial and commercial. Institutional buildings. These two categories of rooftops tend to have larger, flat surface areas, accounted for another one-fifth, according to the news report.
Residential builds would make a substantial contribution and benefit by installing rooftop solar, as well the researchers found. They could produce more electricity per square foot of rooftop space because many of them have sloped roofs, for example.
Cleveland city leaders have set a goal of achieving 100% renewable energy by 2050. The study could be a very valuable resource in helping realize that, the news report highlights.
“A lot of times people will maybe make an assumption that maybe solar isn’t something that can really work in someplace like Cleveland,” said Nicholas Rajkovich, an assistant professor at the University at Buffalo’s School of Architecture and Planning, who has consulted with Cleveland and Cuyahoga County on their sustainability work. “Something like this [the NASA DEVELOP analysis], where you get good data to see exactly what that energy resource is and where to target resources is really helpful.”
