fast solar permit

Solar permitting and interconnection are crucial for ensuring safety, compliance with regulations, and proper installation of solar systems. A streamlined permitting and inspection process allows quicker adoption of solar photovoltaic (PV) systems, promoting access to clean energy sources. At GreenLancer, we have specialized in solar permitting and engineering services for over a decade. We conducted a study of the average residential solar permitting and interconnection times for solar energy projects under 10 kilowatts (kW) to determine the leaders in rapid solar energy adoption. 

Criteria for Evaluating the Solar Permit Application Process

We used several data points to analyze the solar permitting process across numerous states. Utilizing 2022 data from NREL's SolarTRACE platform, we analyzed the average solar permit application, pre-installation interconnection, inspection, and post-installation interconnection times.

Our study also considers which states have policies aimed at accelerating and improving the solar permitting process. This includes measures such as standardized application procedures, online submission systems, and efforts to reduce administrative burdens on solar installers. 

SolSmart Designations

Many cities and counties across the country have also earned SolSmart awards. This national designation program recognizes communities for making it faster, easier, and more affordable to install solar panels. Based on their solar-friendly policies and practices, the program awards communities with Gold, Silver, or Bronze designations in one of five categories: permitting and inspection, planning and zoning, government operations, community engagement, and market development to encourage local solar energy use.


Some communities have adopted  SolarAPP+, an online solar permitting platform designed to streamline and accelerate the approval process for residential solar energy installations. We used data from the National Renewable Energy Laboratory website as of 9/30/2023.


Our study includes the states of Arizona, California, Colorado, Florida, Georgia, Illinois, Massachusetts, Michigan, Nevada, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Texas, and Virginia, which have some of the largest solar energy markets in the United States.
