Path-Q Solar
How can I tell whether net metering or another export arrangement applies to my system?
Answer
Check the utility's current distributed-generation tariff and interconnection terms for the property's service address. The applicable arrangement may be net metering, a credit for exported energy, avoided-cost compensation, or another structure, and it can depend on system size, customer type, application date, and whether a battery is included.
Key points
- The utility tariff, not the installer’s description alone, determines how exports are credited.
- Compare the credit value and treatment of unused credits with the value of electricity bought from the grid.
- Ask whether the arrangement can change when tariffs change or when the system is modified.
What it depends on
- Utility and service territory
- System size and export capacity
- Application or approval date
- Battery configuration and whether export control is required
- Current tariff and interconnection rules
Risks and trade-offs
- A system may produce substantial energy but provide less bill value if exports receive a lower credit than imported electricity costs.
- Adding panels or storage later may trigger a new review or alter the applicable arrangement.
- Marketing terms such as 'net metering' may not describe the actual credit calculation.
Information you may need
- Utility name and service address
- Proposed system size and battery details
- Current export tariff and interconnection agreement
- Rules for credit carryover, expiration, and settlement
