A net metering interconnection agreement Annexure V is the schedule attached to your utility’s interconnection contract that spells out the technical and operating terms for your solar system. Reading it closely lets you confirm your system specs, understand your responsibilities, and avoid the holdups that delay permission to operate. This guide explains what Annexure V usually contains and how to work through it before you sign.

What Annexure V Typically Covers

Exact layouts vary by utility and state regulator, so always check your own copy. In most versions, Annexure V is a technical schedule that records the equipment and limits tied to your interconnection. Expect it to list:

  • The inverter make, model and rated AC output
  • Total DC array size and module count
  • The point of interconnection and meter number
  • Protection settings, such as anti-islanding and voltage and frequency trip limits
  • Any required disconnect switch location and its accessibility rules

Because these entries become the reference for your utility’s inspection, a single wrong figure can stall your project. Match every number to your permit drawings and equipment labels.

Step-by-Step: Reviewing the Schedule Before You Sign

  1. Compare the inverter data. Copy the model and AC rating from the spec sheet, not from a sales quote, and enter them exactly as printed.
  2. Check the system size. Confirm the DC kW figure matches your engineered layout. Utilities often compare this to the interconnection application.
  3. Verify the meter and service details. Make sure the account number and service address match your utility bill.
  4. Confirm the disconnect requirements. If the schedule calls for a visible, lockable disconnect within sight of the meter, check that your electrician’s drawing shows one.
  5. Note any export or capacity limits. Some agreements cap export or require a smaller inverter size than the panel array. Record these limits now so they do not surprise you at commissioning.

Matching Annexure V to Your Installation

Once the agreement is signed, the installer and utility use Annexure V as the benchmark during the final inspection. Put the schedule next to your as-built drawings and walk the site. Photograph inverter nameplates, the disconnect, and the meter so you can answer any follow-up questions quickly.

If something on the ground differs from the schedule, ask the installer to file a revision before the utility inspects. Small corrections are easy to make early and frustrating to fix later. If your net metering rules changed after you applied, check how they affect your schedule; our guide to What Is a Net Metering Agreement? A Homeowner's Step-by-Step Guide explains the basic framework behind these documents.

Common Mistakes

  • Signing before the technical schedule is complete, which leaves blank or placeholder entries.
  • Using inverter or panel data from a quote instead of the installed equipment.
  • Assuming Annexure V is the same across utilities. Terms differ between providers.
  • Ignoring export limits, then discovering them only after the system is energized.
  • Failing to keep a signed, complete copy for your records and future service requests.
  • A weatherproof label printer helps you mark the disconnect and service panel as your agreement and local code require. View on Amazon
  • A digital multimeter lets you confirm voltage and circuit details against the values listed in your schedule. View on Amazon
  • A clamp meter is useful for checking current on the AC side during commissioning checks. View on Amazon

FAQ

Is Annexure V the same as the main interconnection agreement?

No. The main agreement sets the legal terms, while Annexure V is the technical schedule attached to it. Both matter, so read them together.

What if my installed equipment differs from what is listed?

Request a revised schedule from your utility before final inspection. Your installer usually handles the paperwork, but you should confirm it is filed.

Should a licensed professional review this document?

Yes, especially for protection settings and disconnect requirements. Consult a licensed electrician or your installer before signing, since errors can affect safety and approval.

Conclusion

Annexure V turns your solar design into a set of verifiable technical terms. Check every figure against your equipment and drawings before you sign, and keep a complete copy on file. Doing this early prevents most of the delays homeowners run into at inspection.
