Seventy-nine Percent of all Rooftops Analyzed are Technically Viable for Solar

Google and Project Sunroof recently collected data on the areas in the United States that would be the most viable to produce solar power energy. They collected data covering over 60 million buildings.

This project does an excellent job of locating and connecting with the cities that can have the biggest impact against carbon emissions caused by climate change.


They released the top ten cities with the highest potential for solar power production. Those cities include:

  1. Houston
  2. Los Angeles
  3. Phoenix
  4. San Antonio
  5. New York
  6. San Diego
  7. Jacksonville
  8. Oklahoma City
  9. Dallas
  10. Albuquerque

Google also reported data from their nationwide research.

  • Seventy-nine percent of all rooftops analyzed are technically viable for solar, meaning those rooftops have enough unshaded area for solar panels.
  • Over 90 percent of homes in Hawaii, Arizona, Nevada and New Mexico are technically viable, while states like Pennsylvania, Maine and Minnesota reach just above 60 percent viability.
  • Houston, TX has the most solar potential of any U.S. city in the Project Sunroof data, with an estimated 18,940 gigawatt-hours (GWh) of rooftop solar generation potential per year.

“If the top ten cities above reached their full rooftop solar potential, they’d produce enough energy to power 8 million homes across the US.” – Joel Conkling, Product Manager at Google
