Arizona Utilities Approve Pre-Install Interconnection Applications for Rooftop Solar at Dramatically Different Speeds
Project data from the SolarTRACE database for rooftop solar installations 1-10 kilowatts from 2021 shows the wide variation in Arizona utilities' pre-installation interconnection timelines compared to the state median.
The charts compare median pre-installation interconnection times for individual utilities to state-level median pre-installation interconnection times for solar installations under 10 kW installed in 2021. Utility medians range from significantly higher than state medians to significantly lower than state medians.
