Path-Q Solar
How should a contract define the system's expected completion date?
Answer
It should define completion as a sequence of measurable milestones rather than only an approximate installation date. The contract should identify target dates, dependencies, permitted extensions, notice requirements, and what counts as completion, commissioning, and permission to operate.
Key points
- Separate design approval, permitting, equipment delivery, installation, inspection, utility approval, and commissioning.
- State whether delays caused by permitting, utility actions, weather, or customer changes are treated differently.
- Define the evidence required to show the system is complete and operational.
- Specify remedies, cancellation rights, or payment consequences for material delay where applicable.
What it depends on
- Permitting and inspection process
- Utility interconnection process
- Equipment availability
- Customer approvals and site readiness
Risks and trade-offs
- An aggressive fixed date may be unrealistic if third-party approvals are outside the installer's control.
- An open-ended schedule can leave the homeowner exposed to prolonged delays.
- Paying before commissioning weakens leverage if the system is incomplete.
Information you may need
- Proposed milestone schedule
- Installer-controlled versus third-party dependencies
- Definition of substantial completion and final completion
- Delay and payment provisions
