Questions homeowners ask
Can every DEC home add solar that exports to the grid?
DEC says some parts of its territory cannot accept additional solar generation feeding its lines. Confirm the actual address before relying on an export-based proposal.

What does the yellow map category mean?
DEC describes yellow areas as allowing non-export solar. Ask for the approved design and control requirements; a salesperson’s label alone does not establish compliant non-export operation.

Does the map approve my installation?
No. DEC says map boundaries and substation statuses are approximate and further analysis is needed before interconnection approval. Keep its actual project response.

Which application should the installer use?
DEC lists separate export, non-export and battery-storage applications. Ask which current application fits the proposed equipment, size and operating mode before submission.

What does the utility meter record?
DEC describes a meter recording surplus energy not used onsite. Ask which meter and billing treatment apply to your approved configuration; do not equate exports with all production.

Does the separate grant involve renewable-credit ownership?
The Solar Grant Delaware overview says DEC system owners must transfer their SRECs to receive its one-time grant. Obtain the actual agreement and clarify scope, eligibility and obligations before assigning credits. A grant is separate from interconnection approval.

When buying a solar home, is ordinary service transfer sufficient evidence?
DEC describes ordinary service transfer by contacting its member-service team. As an editorial precaution, separately request the solar application, operating records, equipment scope, billing terms and any grant agreement. This guide does not determine transfer rights or continued approval.

Your decision checklist
- Confirm DEC is the actual serving electric provider for the address.
- Review the utility-linked map and retain the dated question sent to DEC.
- Ask whether export, non-export or battery scope is being proposed.
- Identify the correct current application and who submits missing records.
- Keep actual utility approval and metering information in a private folder.
- Review any grant agreement and renewable-credit assignment separately.
- For a home purchase, resolve service, solar and contract handover questions.

Keep map questions and application decisions traceable
| Record | Evidence and next question |
|---|---|
| Service evidence | Actual utility and private service address; keep the public example anonymous. |
| Map question | Date reviewed, category shown, uncertainty at a boundary and written utility response. |
| Proposed operation | Export or non-export intent, equipment scope and the installer’s explanation. |
| Application record | Current form identified, submission reference, corrections and responsible party. |
| Actual decision | Utility response, conditions, missing documents and metering questions. |
| Grant documents | Program agreement, credit-ownership terms and unresolved eligibility questions. |
| Home handover | Ordinary service arrangements, private solar folder and written answers about existing obligations. |
Fictional boundary example: a homeowner’s proposal assumes export revenue while the property appears near two map categories. Save the proposal assumption and ask the utility to identify the actual project conditions. Do not treat a neighboring property’s arrangement as a decision for this one. These are invented circumstances, not a claim about any real address.
Fictional document example: a buyer receives a solar invoice and a separate grant agreement with missing attachments. List the records held, unresolved terms and the parties who can answer. Obtain the complete documents before treating a marketing estimate as proof of income, ownership or continuing eligibility.
Reviewed October 7, 2026 against DEC’s solar interconnection guidance, its ordinary service-transfer guidance and the linked Solar Grant Delaware overview. Use the map linked by DEC with the utility’s stated limitations. This guide explains DEC’s published screening guidance; it does not assess a private address or extend Delmarva Power’s rules to cooperative customers.
The organizer and fictional examples are editorial preparation aids, not additional utility or legal requirements. Request the current rate, complete interconnection instructions and project-specific technical, permit, insurance and fee conditions from the responsible parties. No map category, nearby approval, grant application or salesperson’s estimate guarantees project acceptance, credit ownership, payment or savings. Confirm the current program agreement; this page does not decide incentive eligibility or interpret every applicable law.
Use existing records and safely visible information. Do not alter inverter controls, test an export limit, open electrical equipment or operate disconnects to demonstrate compliance. Qualified providers and the utility must resolve technical questions. Keep service addresses, account and meter identifiers, credentials, private contracts and household usage out of public examples.
Continue with permit and utility milestones, solar bill and measurement basics, renewable-credit ownership and Delaware rebate program records. Solar Survey AI’s evidence methodology separates observed facts, assumptions and actual decisions. For site concerns, confirm available inspection scope, location availability, qualifications, access, fees and commercial conflicts. Third-party does not automatically mean independent. A survey cannot assign a utility map category, authorize export or approve a grant. Homeowner monitoring connections and planned free remote diagnosis remain coming soon.
