Portland Solar Permit Guide
Portland General Electric (PGE) territory · Multnomah County
Overview
GridPermit collects Oregon residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.
Battery/solar incentive program on record
Oregon Solar + Storage Rebate Program (OSSRP) — Energy Storage System
Statewide Oregon rebate for residential energy storage systems paired with a solar electric system: $300 per kWh of installed storage capacity, up to 60% of net system cost or $2,500 (whichever is less) for low/moderate-income homeowners, or up to 40% of net cost or $2,500 for other homeowners. Rebates are issued to ODOE-approved contractors, who pass savings to the customer at time of installation (no upfront payment/reimbursement wait). System must have 'islanding' capability. As of this record's verification date (June 2026 update on ODOE's own page), the program is NOT currently accepting new rebate reservation applications — the $1.1 million reopened on June 15, 2026 was fully reserved almost immediately. This is a genuine, temporary funding-exhaustion pause, not a program termination.
Status on file: active. Verify current status before relying on this.
Permit fees
- Prescriptive pathway — Building Permit fee estimate, 3.5 kW or 5.5 kW PV system: $576 (estimated flat fee (identical across the two listed PV sizes))
Per the City's own published fee-estimate table; final fees depend on system size/type and review process.
- Prescriptive pathway — Electrical Permit fee estimate, 3.5 kW PV system: $187 (estimated flat fee)
Per the City's own published fee-estimate table.
- Prescriptive pathway — Electrical Permit fee estimate, 5.5 kW PV system: $265 (estimated flat fee)
Per the City's own published fee-estimate table.
- Prescriptive pathway — Building Permit fee estimate, solar water heating: $576 (estimated flat fee)
Per the City's own published fee-estimate table.
- Prescriptive pathway — Electrical Permit fee estimate, solar water heating: $143 (estimated flat fee)
Per the City's own published fee-estimate table.
- Engineered Systems pathway — Building Permit fee estimate, 3.5 kW or 5.5 kW PV system: $770 (estimated flat fee (identical across the two listed PV sizes))
Per the City's own published fee-estimate table; the Engineered pathway carries a higher building-permit fee than Prescriptive, reflecting the added plan-review burden.
- Engineered Systems pathway — Electrical Permit fee estimate, 3.5 kW PV system: $187 (estimated flat fee)
Electrical permit fee estimate is identical to the Prescriptive pathway for the same system size.
- Engineered Systems pathway — Electrical Permit fee estimate, 5.5 kW PV system: $265 (estimated flat fee)
Electrical permit fee estimate is identical to the Prescriptive pathway for the same system size.
Rebates
Oregon Solar + Storage Rebate Program (OSSRP) — Solar Electric System
Statewide Oregon rebate for residential solar electric systems: low/moderate-income homeowners receive $1.80/watt(DC), up to 60% of net cost or $5,000 (whichever is less); homeowners not low/moderate-income but eligible for a utility incentive receive $0.20/watt(DC) up to 40% of net cost or $5,000; homeowners not eligible for a utility incentive receive $0.50/watt(DC) up to 40% of net cost or $5,000. 'Net cost' excludes any utility or Energy Trust of Oregon incentive already applied. Rebates are issued to ODOE-approved contractors, who pass savings to the customer directly (no reimbursement wait). As of this record's verification date (June 2026 update on ODOE's own page), the program is NOT currently accepting new rebate reservation applications — the $1.1 million reopened on June 15, 2026 was fully reserved almost immediately. This is a genuine, temporary funding-exhaustion pause, not a program termination.

Utility and generation supplier
Utility
Portland General Electric (PGE)
Generation supplier
Portland General Electric (PGE) (utility)
Net metering mechanism confirmed via the City of Portland's own Solar Permits page (not PGE's own site, which was inaccessible this session): 'Oregon law allows all utility customers to generate their own electricity... Your utility provider will switch out your existing utility meter for a bidirectional net meter... The power you use from your utility is offset by the power you send to the grid and you are only charged for the difference or the net.' Specific PGE program names (e.g. current net metering tariff terms, any successor/Smart-DER-style programs) were not independently confirmed this session since PGE's own program pages could not be loaded.
Interconnection
Not yet verified.
Required documents
- Structural Design Criteria (design sloped roof snow load ≥20 psf, basic design wind speed ≥98 mph and exposure category, solar panel system dead load), stamped by an Oregon-Registered Design Professional (required when: always, unless the exempt solar-tile pathway applies)
- Site Plan (required when: always)
- Fire Access Path (required when: always, except for solar tile installations)
- Roof framing plan (required when: unless the roof uses pre-engineered trusses or the installation uses solar tiles (a roof plan showing panel layout substitutes))
- Roof cross-section (required when: unless the roof uses pre-engineered trusses or the installation uses solar tiles)
- System Racking Attachment detail (required when: always, for both Prescriptive and Engineered pathways)
- Engineering calculations stamped by an Oregon-registered design professional (required when: always for Engineered systems; not required for qualifying solar-tile installs (≤4 psf net installed weight, installed directly over existing sheathing, uniformly supported) — a certifying letter substitutes)
- Electrical Renewable Energy Permit Application (required when: always)
- Plumbing Permit Application (required when: only for solar hot water heating projects)
Inspection steps
- Call for inspection once the permit is approved and construction is underway
- A City inspector reviews the installation on-site for compliance with state building codes
- View real-time inspection results on DevHub
Eligibility constraints
- Property types: residential, commercial
- Max system size (AC): Not yet verified.
- Max system size (DC): Not yet verified.
- Max thermal capacity: Not yet verified.
- Program/pathway: Prescriptive vs. Engineered Systems solar permit pathways
- Other conditions:
- Two distinct review pathways: Prescriptive (roof meets prescriptive standards per the state building code; does not require an Oregon-registered design professional) and Engineered Systems (does require a registered design professional)
- Solar roof tile installations must follow the Engineered Systems process, but are exempt from the registered-design-professional and engineering-calculation requirements if: net installed weight of all above-sheathing components ≤4 psf; tiles are installed directly over existing sheathing with all prior roofing material removed; and all tiles (active and inactive) are uniformly supported over the sheathing — per ORSC Section 905.16 (2021) / OSSC Section 1507.16 (2022)
- A free 15-minute pre-application question appointment is available with a City planner, permit technician, building code/engineering reviewer, or fire safety expert
