Even after solar permits are approved, one of the biggest headaches for contractors is utility interconnection. Delays at this stage can stall cash flow, frustrate customers, and eat into profits. In many U.S. markets, utilities are taking weeks—or even months—to approve interconnections.
This article will break down why delays happen, what contractors can do to minimize them, and how to keep projects moving forward.
Why Utility Interconnection Delays Happen
Unlike AHJs, utilities manage the grid-side approval process, and their timelines vary drastically. Common reasons for delays include:
- Overloaded utility review teams → Especially in states with high solar adoption.
- Incomplete applications → Missing spec sheets, line diagrams, or fee payments.
- Grid capacity issues → Some utilities pause interconnections if circuits are at risk of overload.
- Communication gaps → Contractors don’t always get updates until weeks later.
How Delays Impact Contractors
- Payment Bottlenecks – Many contracts tie final payment to Permission to Operate (PTO). Delays = stuck revenue.
- Customer Frustration – Homeowners expect “solar savings” immediately and may blame the installer for utility delays.
- Project Backlog – Crews can’t be reassigned efficiently if jobs remain in limbo.
Contractor Strategies to Reduce Delays
- Submit Perfect Applications – Double-check that every document (one-line diagram, site plan, spec sheets, signatures) is complete before submission.
- Build Utility Relationships – Establish direct contacts at local utilities to push through urgent cases.
- Track Applications Systematically – Use CRM or project management tools to monitor every interconnection request.
- Educate Customers Upfront – Set realistic expectations about PTO timelines, so you’re not blamed for utility slowdowns.
- Use Pre-Approved Equipment – Utilities often fast-track applications if your inverter and equipment are on their approved list.
