Questions homeowners ask
Where does TEP show the rooftop export credit?
TEP identifies the RCP export payment as Excess Generation Credit in the Power Supply Charges section. Match that line to the export quantity and applicable rate. A production dashboard total includes energy used at home and does not, by itself, establish the utility’s export measurement.

Does the latest published export rate apply to every TEP solar home?
No. TEP describes compensation for a new system at the RCP rate in place when interconnection was requested, for up to ten years. Obtain the actual application record and account terms. Do not substitute today’s published rate for a documented earlier rate or assume the new-system rule controls a legacy transition.

Does grandfathered TEP net metering continue indefinitely?
No. TEP describes a twenty-year period measured from connection to its grid, followed by a transition to RCP compensation and time-of-use service. Request the original connection record, actual maturity date and transition notice before forecasting a bill. Panel age or a seller’s description is not your account’s confirmation.

Can I reverse an early switch out of net metering?
TEP says an eligible customer may request an early transition to RCP, but cannot switch back. Treat that request as a consequential account decision. Ask TEP for the applicable plan, credit treatment and written explanation before deciding; our guide does not recommend that election for your household.

What happens when a monthly solar credit exceeds the bill?
TEP’s residential overview says the surplus credit rolls into the next month and that an October credit balance over ten dollars results in a payment. Record the exact balance unit on your statement. Ask TEP to identify your balance’s unit, rider and settlement treatment.

Can I add panels and assume my existing export arrangement stays unchanged?
No. TEP requires a new application for additional panels or an inverter and explains that expansion can affect the export arrangement. Give the installer and utility the actual proposed equipment and size change. Request a written account-specific explanation before relying on the existing rate in a new quote.

Why can charges remain when my panels generated plenty of energy?
TEP’s bill guide separates delivery and power-supply charges and explains that the basic service charge does not vary with usage. Its service-information section identifies the pricing plan and billing dates. Keep each charge and credit visible; a monthly generation total alone cannot explain the full amount due.

Your decision checklist
- Confirm TEP is the actual utility and identify the account rider.
- Locate separate connection and interconnection-request records.
- Match the export credit to its quantity, rate and period.
- Keep currency balances separate from banked energy units.
- Retain remaining charge lines and settlement records.
- Request written transition or expansion treatment.
- Resolve missing evidence before making a plan or equipment change.

Keep the export arrangement and balance units visible
| Separate record | Evidence and next question |
|---|---|
| Account and rider | Actual serving utility, pricing plan, billing period and written rider identification. |
| Original project | Connection date, interconnection request and system scope; keep distinct dates separate. |
| Export calculation | Utility export quantity, applicable rate and Excess Generation Credit line. |
| Credit balance | Actual currency or energy unit, carryover and settlement explanation. |
| Remaining charges | Delivery, supply, basic service and other lines; avoid treating a credit as the full bill. |
| Transition or expansion | Issued notice or proposed equipment change; identify unresolved rate questions. |
| Next response | Responsible utility or installer contact, written question, reply and dated follow-up. |
Fictional bill example: an owner compares a dashboard’s monthly generation figure with the utility’s export line and calls the difference missing credit. Put each figure, unit and period in separate rows, and request the actual utility calculation. Account for energy used in the home before treating every generated kilowatt-hour as an export. A mismatch is a question to investigate, not evidence of equipment failure or an incorrect bill by itself.
Fictional upgrade example: a household receives an expansion proposal that budgets credits using its old statement. Keep the existing project record alongside the proposed equipment list, and ask who will obtain the utility’s written rate-treatment response. Do not change equipment or submit a rate election merely to test an income assumption. Evaluate the technical design and account decision with the appropriate providers.
Reviewed October 7, 2026 against TEP’s RCP explanation, net-metering transition FAQs, residential solar overview and bill guide. This concerns Tucson Electric Power residential accounts, not every Tucson address, APS, SRP or every Arizona utility. The overview uses KBH terminology while the transition FAQ distinguishes financial credits from energy credits; retain actual bill units and ask TEP which treatment applies. We do not quote current energy rates, determine a personal maturity date, interpret every tariff condition or promise savings. Current tariff terms and written utility confirmation control individual account questions. Our organizer and fictional examples are editorial preparation aids.
Continue with Tucson permit and utility milestones, bill measurements, solar-home transaction evidence and production-problem records. Solar Survey AI’s evidence methodology separates observations from unresolved questions. Confirm available inspection scope, location availability, qualifications, access, fees and commercial conflicts for a technical concern. Third-party does not automatically mean independent. A survey cannot approve an expansion, choose a utility plan or guarantee credit settlement. Homeowner monitoring connections and planned free remote diagnosis remain coming soon. Do not open equipment, change settings or climb onto a roof to investigate these records.
