Clean Power Finance today unveiled a nationwide study of solar permitting and the obstacle it poses to the widespread adoption of residential solar. The study, the largest of its kind to date, provides quantifiable evidence of the negative effects complex permitting regulations have on U.S. solar installers and also on the authorities having jurisdiction (AHJs), including municipalities and utilities, who oversee permitting processes.

Clean Power Finance undertook the study as part of preparations for the National Solar Permitting Database (NSPD), a free, online database of permitting requirements from across the U.S. that is funded in part by Clean Power Finance and in part by a Department of Energy SunShot Initiative grant. The study's objective is to establish baseline metrics prior to the deployment of the NSPD that can be compared to metrics taken after the NSPD is fully implemented, and to provide direction to the industry about areas for improvement.

"Strong initial interest in the National Solar Permitting Database makes it clear that people want to address permitting obstacles but aren't quite sure where to start," said James Tong, senior director at Clean Power Finance and project lead. "This study provides valuable data that will help identify areas for improvement and cooperation that will bring down costs for everyone and advance the adoption of solar."
