Solar permitting, inspection, and interconnection cycletimes and requirements

Description

Sixteen small-to-large residential PV installers submitted project-level data for analysis, which included timestamps for major components of the permitting, inspection, and interconnection process as well as contract and installation dates. NREL calculated median timelines for these processes across the authorities having jurisdiction (AHJs) and utilities represented in the data. Also included are relevant permitting requirements for AHJs and interconnection process requirements for utilities. This dataset represents the underlying results shown in the Solar Time-based Residential Analytics and Cycle time Estimator (Solar TRACE) viewer. This dataset has been reviewed but errors may exist and it may not be comprehensive. Errors in the sources (e.g., AHJ permitting requirements lists from data partners) may be duplicated in the dataset.

5 This is the cycletime results and permitting/interconnection requirements dataset. Results are delineated by AHJ/utility combination and by year (2017-2023), project size (1-10kW, 11-20kW), and project type (PV only, PV+storage). https://data.nrel.gov/system/files/160/1726262615-SolarTRACE%20data%209-13-24.xlsx
5 DEPRECATED: This is the cycletime results and permitting/interconnection requirements dataset. Results are delineated by AHJ/utility combination and by year (2017-2021) and project size (1-10kW, 11-50kW). https://data.nrel.gov/system/files/160/SolarTRACE%20data%207-8-22.xlsx
