Path-Q Solar
Can a zero-export design avoid grid approval, or are other approvals still needed?
Answer
Zero export does not automatically eliminate approvals. The project may still require utility review, electrical permits, building or fire approvals, inspections, equipment certification, and compliance with operating and anti-islanding requirements. Only the relevant authority can confirm which approvals apply.
Key points
- Zero-export controls must reliably prevent unintended export under normal and abnormal conditions.
- The utility may still need to approve the equipment, control scheme, service connection, or change in operating mode.
- Separate permits may apply to electrical work, structural work, batteries, generators, or commercial occupancy.
What it depends on
- Jurisdictional permit rules
- Utility interconnection procedures
- System architecture and certified control equipment
- Whether storage, backup operation, or service changes are included
Risks and trade-offs
- Control failure can cause unauthorized export or unsafe operation.
- Assuming no utility review can cause inspection, energization, or insurance problems.
- Zero-export operation may reduce the value of excess generation and require ongoing monitoring.
Information you may need
- Utility zero-export requirements
- Equipment certifications and one-line diagram
- Applicable building, electrical, fire, and planning rules
