Streamlined Solar Permitting for Rooftop PV Systems


The Department of Energy’s SunShot Initiative awarded CSE $1.2 million to help overcome barriers in local jurisdictional permitting and regulatory processes that add to the cost of small rooftop photovoltaic (PV) systems and slow solar adoption by residents and small businesses.

The project team conducted rigorous research and analysis of existing best practices among authorities having jurisdiction (AHJs) throughout California to design streamlined solar permitting packages ideally structured for AHJs nationwide. The goal was to provide standardized and cost-effective permitting processes, making it more affordable for people to choose solar energy. Currently, jurisdictional variations in permitting and regulatory procedures can add nearly $1 per watt to system costs.
