Questions homeowners ask
Does this guide cover every Portland-area home?
Confirm the parcel’s permitting authority and the electric provider on the actual account. This guide addresses City of Portland permitting and Portland General Electric where it serves the property. A Portland mailing address alone does not establish either. PGE here means the Oregon utility, not California’s PG&E.
What property rules should the applicant check first?
Portland directs applicants to research the property through PortlandMaps. Plan, historic or conservation districts can have special rules. Ask the contractor to document applicable site constraints before treating a standard proposal as ready for permitting.

Which solar permit path applies?
Portland describes prescriptive and engineered review paths and says roof construction must be assessed to select the route. Ask the applicant for the criterion check and any required professional design. Do not choose a route from system size alone.

Can photographs replace the submitted solar plans?
The City requires scaled plans and does not accept photographs, sketches or Google Maps images as plans. Ask the applicant for the required document checklist and submitted version. Site observations and permit drawings serve different purposes.

What should I keep when the City requests corrections?
Portland describes electronic corrections and a pre-issuance review before the permit is ready to issue. Keep the request, response, revised plan and current status. A submitted response is not the same as an issued permit.

What inspections finalize the City permit?
Portland lists structural and electrical inspections for solar and residential completion codes 199, 299 and 999. An inspector must approve work to finalize the permit. Ask the contractor which inspections apply to your permit records and what remains incomplete.

What if an inspection cannot be completed?
The City’s inspection page identifies lack of access, incomplete work and code violations as reasons work may not be approved. Keep the actual report and corrections. Arrange access through the contractor and inspector; do not open equipment or climb onto the roof yourself.

Why check PGE’s net metering map before construction?
PGE identifies areas where limited feeders may require design changes for grid safety and reliability. It directs customers to contact its net metering team before applying and wait for application approval before construction. A map view is not project approval.

Does an installer’s PGE claim establish endorsement?
PGE says it does not partner with a specific installer and recommends multiple bids. Ask a salesperson to explain any claimed relationship in writing. Compare contractor qualifications, scope and conflicts rather than inferring utility endorsement.

Why does the PGE bill differ from the inverter’s generation total?
PGE’s bidirectional meter records electricity received from and supplied to the utility, not all system production. Electricity used directly in the home belongs in a separate measurement. Compare matching dates and units before labeling a difference a fault.

What happens to unused PGE energy credits at annual true-up?
PGE describes a March annual reset, with unused credits donated to low-income bill assistance programs. Customers can request a different ending month. Confirm your account’s actual cycle and current rate schedule; do not assume unused credits become a cash payment.

What if construction changes the approved solar plan?
Portland says most changes to approved plans require a permit revision and advises asking the City inspector when uncertain. Preserve both versions and the official answer. Separately ask PGE whether the revised equipment or configuration changes its review.

What can a site assessment help resolve?
Identify the missing observation: roof configuration, accessible conditions, shade inputs or an unexplained layout assumption. Solar Survey AI’s methodology explains how site evidence is documented. Confirm the available homeowner scope, qualifications, exclusions and conflicts. An assessment does not issue permits, determine utility eligibility or authorize operation; request the actual authority and utility completion records.
Your decision checklist
- Confirm parcel jurisdiction and account utility.
- Record the permit path and the applicant’s supporting review.
- Retain submitted and approved plans with revision dates.
- Track corrections and inspection completion separately.
- Ask PGE about feeder constraints before relying on a construction date.
- Keep the actual utility application approval and final operating records.
- Confirm the billing cycle, energy-credit balance and true-up treatment.
- Collect equipment, warranty and operating handover records.

Keep the City and utility tracks visible
| Track | Record to request | Unresolved question |
|---|---|---|
| Site and scope | Parcel jurisdiction, account utility and dated project scope | Does this process cover the actual property and work? |
| City application | Permit reference, path and submitted plan version | Which reviewer request remains open? |
| City completion | Inspection reports, corrections and final record | Did the authority approve the installed work? |
| PGE review | Application reference, written decision and conditions | What does the utility approval authorize? |
| Operation and bills | Final operating records, meter information and credit cycle | Who confirms readiness and the actual account treatment? |
Example: the contractor shows an issued City permit while the utility application is still being reviewed. Keep each milestone in its own row. Ask for the PGE decision and conditions before treating the construction schedule as confirmed. A City document does not fill a missing utility record.
Illustrative energy accounting only: a system produces 500 kWh, the home uses 300 kWh directly and 200 kWh go to the grid. The utility meter’s exported amount is 200 kWh, not 500 kWh. The difference is explained by direct consumption in this simplified example; it is not a forecast, a PGE bill calculation or evidence about a real system.
Example: a salesperson describes a battery package as including all approvals. Ask for a written equipment list, installation scope and the responsible applicant for each review. Keep the promised backup loads separate from utility credits, and request the actual operating limitations before relying on the package.
Check current instructions with the City and utility when scheduling. Some older inspection-page text describes pandemic-era video procedures; confirm the current visit and access arrangements rather than assuming those procedures still apply.
Continue with bill and export measurements, roof and backup limits, installer comparison questions and assessment independence and scope. Explore Oregon survey resources, Solar Survey AI’s evidence methodology and site-survey services; confirm actual availability for your property.
