Path-Q Solar
How should I verify whether my property is eligible for grid interconnection?
Answer
Verify eligibility with the serving utility or network operator before committing to a system. The utility will assess the proposed system, point of connection, existing service, export arrangement, and any required studies or upgrades.
Key points
- Identify the correct utility and its distributed-generation interconnection process.
- Ask whether the property has capacity for the proposed export level and whether a preliminary screening is available.
- Confirm whether the service, transformer, feeder, meter, or protection equipment may need modification.
- Treat interconnection as unconfirmed until the utility provides the applicable approval or permission to operate.
What it depends on
- Utility and network-operator rules
- Proposed system size and inverter characteristics
- Existing electrical service and point of connection
- Expected export and any storage or export-limiting controls
- Property-specific grid capacity
Risks and trade-offs
- A system may be technically installable but still require studies, limits, or upgrades before it can export.
- Required upgrades can increase cost and delay the project.
- Designing around assumed approval can lead to redesign or contract disputes.
Information you may need
- Serving utility and service address
- Recent electrical-service information
- Proposed system size, inverter type, and storage configuration
- Whether the system will export all generation, limit export, or operate without export
