Questions homeowners ask
Why can received energy differ from inverter production?
CoServ defines DEL as electricity supplied from the grid and REC as surplus sent back after household use. The meter measures grid exchange; an inverter reports solar output. Compare the actual periods and definitions before treating a difference as lost generation.

How does ordinary DG Buyback treat a remaining credit?
The rate page describes compensation at avoided wholesale cost, applying credits to listed bill charges and carrying remaining credits to the next bill. Confirm your accepted rate and current billing basis; compensation is not universally the retail purchase price.

Can a pre-February 2023 system try buyback and then return to net metering?
CoServ says systems installed before February 1, 2023 may request the buyback route, but cannot switch back to the DG net-metering rate afterward. Resolve your actual installation record and consequences before requesting a change.

Does adding a battery leave the existing DG application sufficient?
The solar FAQ requires an additional DG application for system changes, including more panels or battery storage. Ask CoServ and the responsible contractor to confirm the actual scope and required review before relying on an older approval.

Which record establishes the utility’s operating authorization?
CoServ says operation requires approved interconnection and its PTO letter. The Tariff Acknowledgment Agreement is part of the process. Retain the actual signed agreement and authorization; a submitted application or installer completion message is not the PTO.

Does the Base battery program preserve ordinary buyback credit treatment?
The solar FAQ describes a switch from DG Buyback to DG with Reliability Plus. It describes retail credit up to usage in that billing period, without credit carryforward beyond the month. Review the actual proposed rate and provider agreement before enrollment; a battery offer can change the billing comparison.

Is backup availability guaranteed after a grid-support event?
CoServ warns that shared battery dispatch can leave less backup energy, or none, before recharging after a grid event. Ask about reserve and load assumptions. Do not treat a capacity label as a promised outage duration.

Your decision checklist
- Identify the actual CoServ electric rate and effective date.
- Separate delivered, received and inverter production quantities.
- Compare credit limits and carryforward for the proposed rate.
- Resolve legacy-switch consequences before any request.
- Track additional equipment applications and actual PTO.
- Read provider, dispatch and backup obligations before enrollment.
- Keep acceptance, responses and unresolved questions traceable.

Keep rate choices, approvals and battery limits traceable
| Record | Evidence and next question |
|---|---|
| Actual rate | Account-specific rate name, effective date and applicable tariff; preserve older accepted terms separately. |
| Grid measurement | Billing period, delivered and received energy, meter basis and separately labeled inverter production. |
| Credit treatment | Applicable compensation method, charges offset, carryforward rules and the utility’s written explanation. |
| Legacy choice | Actual installation date, current eligibility, proposed switch and written consequences before any request. |
| Equipment change | Existing and proposed equipment, contractor scope, application, acknowledgment and operating authorization. |
| Battery participation | Provider agreement, rate change, dispatch and backup limits, address eligibility and actual acceptance. |
| Follow-up owner | Named utility or provider contact, unresolved question, response date and next agreed action. |
Fictional legacy-rate example: an owner receives a proposal using an ordinary buyback calculation, while the account folder contains an older net-metering acceptance. Preserve both and request a comparison tied to the actual account. Do not submit a rate-change request simply to see whether it helps; first resolve the stated consequences and the assumptions behind the proposal.
Fictional battery example: a household compares a battery offer only by its installation charge, leaving its solar credit assumptions unchanged. Add columns for the current and proposed rate, bill periods, credit cap, carryforward treatment, provider obligations and backup limitations. Ask the utility and provider to explain each unresolved item in writing. The organizer does not calculate savings or determine suitability.
Reviewed October 7, 2026 against CoServ’s residential DG-rate sections, solar installation and change guidance and Base battery program. The program page currently excludes Lantana residents and members using Nonstandard Metering Service. Confirm address and account eligibility with the responsible parties; electric membership alone is not acceptance. No program signup, rate switch, provider connection or product-permission change has been performed by this guide.
This resource concerns CoServ electric accounts, not every Texas retail-provider contract. Keep the applicable tariff and written account decision with the proposal. No current price, total fee, incentive, tax entitlement, processing deadline, savings or outage duration is promised. The worksheet and invented examples are editorial preparation aids, not additional legal requirements, a rate recommendation or an enrollment approval. Obtain appropriate advice about actual contract obligations.
Use existing records and safely visible information. Do not open electrical equipment, alter wiring, operate switches or perform electrical tests to investigate a bill. Qualified providers should address technical work. Keep account identifiers, serial numbers, credentials, household data and private agreements out of public examples. If health depends on electricity, prepare a separate medical-device power plan with responsible care and equipment professionals; this guide does not prescribe a suitable battery.
Continue with bill and measurement basics, battery planning and battery participation records. Solar Survey AI’s evidence methodology separates observations, assumptions and confirmed decisions. For site or equipment concerns, confirm available inspection scope, location availability, qualifications, access, fees and commercial conflicts. Third-party does not automatically mean independent. A survey cannot approve a utility application, change a tariff or guarantee a battery outcome. Homeowner monitoring connections and planned free remote diagnosis remain coming soon.
