Path-Q Solar

How should I evaluate a solar installation timeline that depends on several approvals?

Answer

Treat the timeline as a sequence of dependencies rather than a single promised completion date. Ask which approvals are required, who controls each one, what starts the clock, what happens if an approval is denied or delayed, and whether the contract gives you cancellation or refund rights.

Key points

  • Separate design, permitting, utility interconnection, financing, equipment procurement, installation, inspection, and permission-to-operate milestones.
  • Distinguish estimated dates from contractual deadlines.
  • Require the installer to provide status updates and identify the party responsible for each approval.
  • Check whether payment obligations begin before approvals are complete.

What it depends on

  • Local permitting and inspection processes
  • Utility interconnection requirements
  • Equipment availability and project complexity
  • Installer coordination and contract delay provisions

Risks and trade-offs

  • A short estimated timeline may omit approval or utility dependencies.
  • A fixed completion promise may be unrealistic when third parties control key steps.
  • Long delays can affect financing, roof plans, cash flow, and expected savings.

Information you may need

  • A milestone schedule with dependencies
  • Responsible party and target date for each approval
  • Delay and cancellation rights
  • Payment obligations during delays

Your next step

What to do next

Request a written critical-path schedule showing each approval, its responsible party, the dependency that follows, and your remedies if the schedule slips.
