Solar Permit Package Checklist

A solar permit package should let the reviewer locate the proposed work, understand its electrical and structural implications, and check the evidence supporting the design. Build it from the requirements for the actual project address. A drawing labeled “permit-ready” does not establish that the local submission is complete.

This checklist focuses on US rooftop PV, with additional checks for storage and service work. It is a package-preparation guide for designers and installers, not an engineering design, national code template or approval certificate. Official examples were checked on 30 September 2026; verify the current instructions at submission.

Establish the submission route before drafting

Identify the authority having jurisdiction, utility, building occupancy and full scope. A residential roof array, ground mount, ballasted commercial installation and PV-plus-storage retrofit can require different documentation and review.

Create a jurisdiction record containing:

• Project address and parcel identifier, where requested.
• Current application page, checklist and prescribed plan template.
• Applicable adopted code editions and local amendments, confirmed for the submission.
• Required permits, outside-agency approvals and submission sequence.
• Who may prepare, sign or seal each document.
• PDF, portal, filename and revision instructions.
• Date checked and contact for unresolved questions.

San Diego’s Information Bulletin 301 illustrates why scope comes first: electrical, building and combination permit routes depend on the work, and its qualifying residential template route differs from other installations. Treat that bulletin as a San Diego example, not a rule for every US city.

Do not assume the newest published NEC edition has been adopted locally. Do not insert a default national setback, equipment clearance or professional-seal exemption without its applicable basis.

Package contents: a topic checklist, not a required sheet count

Keep the useful sheet-by-sheet organization, but adapt it to the local format. Topics may share a drawing, while a complex project may need additional details. A three-line diagram is not automatically required just because the project has batteries.

Assign each applicable requirement a drawing number or document reference. Record an item as “not applicable” with a reason; do not quietly omit it.

Cover sheet and application checks

Keep the address, scope and revision consistent across the application and drawings. Distinguish PV DC nameplate capacity from inverter AC rating and battery energy capacity; they describe different things.

Show the project contacts, preparer and responsible contractor as required. List the applicable code basis after verification. Avoid pages of generic notes describing equipment or work that the project does not contain.

Check that the index matches the uploaded set and that superseded sheets have not been mixed into the current revision. Include an outside approval or interconnection reference where the local process calls for it. Do not publish sensitive utility-account details in public marketing documents merely because a project form requests them.

Site and roof plan checks

The site plan should orient the reviewer to the structure, array and related equipment. Distinguish existing equipment from proposed work, and show relevant routing and access. Use the authority’s required scale and dimensions rather than an arbitrary drawing convention.

For the roof plan, check:

• Roof outline, slope and orientation for the surfaces used.
• Existing obstructions and equipment that affect the design.
• Module positions, count and dimensions consistent with the electrical design.
• Applicable fire-access pathways, ridge clearances and setbacks with dimensions and references.
• Mounting system, attachment detail references and routing.
• Locations of relevant inverter, disconnect and shutdown equipment.

There is no universal 18-inch clearance around every obstruction. A skylight should not be relabeled a smoke vent without evidence of its actual function. Where an alternative access arrangement is proposed, document the required review instead of describing the alternative as already approved.

The site survey evidence package can help organize measurements and photographs behind these drawings. Mark assumed framing or uncertain existing equipment clearly and resolve it through the responsible survey or professional review.

Electrical diagram and calculation checks

The single-line diagram should show how the PV system connects to the existing electrical installation. For storage, distinguish the charging, export and backup arrangements; a generic battery symbol does not explain isolation during an outage.

Cross-check:

• Module, inverter, optimizer or microinverter models and quantities.
• String or branch configuration, where relevant.
• Existing service equipment ratings and the proposed interconnection arrangement.
• Disconnecting means and protective devices required for the design.
• Conductor and raceway information, grounding and bonding.
• Applicable voltage, current, ampacity, protection and interconnection calculations.
• Calculation assumptions and manufacturer ratings used as inputs.

Do not use one arithmetic shortcut as a complete electrical design. Maximum string voltage depends on the actual temperature basis and equipment data. Conductor sizing depends on the circuit, installation conditions and applicable rules. An inverter’s DC array wattage is not its AC output current, and a simplified busbar expression is not the only possible interconnection method.

Have the responsible qualified designer establish the applicable method and check its conditions. If a diagram calls for an external disconnect, show the actual requirement and equipment arrangement; do not claim every string-inverter installation needs the same external devices.

Equipment schedule and evidence packet

Use a model register to prevent substitutions from creating contradictions:

A logo on a sales brochure is not a substitute for the required listing evidence. Keep the supporting documents legible. Do not assign the same listing to every combiner, racking product or shutdown component without checking the actual equipment.

Where a component changes, review compatibility and affected calculations, labels and documents together. Changing only the schedule leaves an internally inconsistent package.

Structural review and professional signatures

Retain the framing and attachment checklist, but verify which structural route applies. Capture the relevant existing structure, roof covering, array weight and mounting configuration. Attachment documentation should explain how the proposed system connects to the structure; uncertain framing needs an explicit resolution plan.

Applicable loads and the design basis belong in the responsible professional’s review. Do not infer adequate roof capacity merely because a generic “3–4 psf” statement appears in the template. Ballast, concentrated equipment loads, structural alterations and existing roof condition can change the assessment.

Confirm who may sign the electrical plans and who may prepare or seal structural calculations. These are separate questions. San Diego’s bulletin, for example, distinguishes authorized PV-plan signatories from structural-calculation signatories. That distinction makes a blanket “California never needs a PE stamp” statement unsuitable.

Keep the actual required signed or sealed documents in the submission. A blank stamp box or generic letter does not establish professional review.

Rapid shutdown, disconnects and labels

For the applicable code and system configuration, document the shutdown approach, equipment and locations needed for review and inspection. Identify the initiation method and provide the relevant listed-system evidence and manufacturer instructions.

Do not state that any microinverter or optimizer makes every configuration compliant. If using a hazard-control system, verify the equipment combination and installation conditions covered by that system.

Build the label schedule from the adopted requirements and proposed system. Record label text, location and supporting reference where requested. Avoid copying dimensions and article numbers from a different edition into a supposedly current national label table. Shutdown controls also do not mean all sunlit PV conductors can be assumed de-energized.

Additional checks for batteries and service work

Storage needs its own scope review. Capture the exact system, energy capacity, location, mounting, disconnecting arrangement, backup configuration and required listing evidence. Show the applicable clearances, separation, openings, access and protective measures using the relevant authority and manufacturer requirements.

Do not turn an individual-unit energy limit into a universal aggregate limit for every location. San Diego’s current bulletin distinguishes individual and location-dependent aggregate storage provisions; it also calls for further review when the applicable conditions are exceeded.

For a service upgrade, document the existing and proposed equipment and any changed conductors, grounding or interconnection arrangement. Confirm the utility’s part in the work. Service upgrades and storage may require additional applications or review; they are not automatically covered by a rooftop PV template.

SolarAPP+: check eligibility and the local process

SolarAPP+ follows an automated route for eligible projects in participating jurisdictions. Its current eligibility page, updated August 2026, distinguishes project types and directs applicants to the applicable checklist. It includes exclusions such as ground-mounted, commercial and ballasted systems. Check the live criteria rather than reusing an older system-size claim.

A SolarAPP+ result does not necessarily complete every local application. Elk Grove’s published process separately addresses outside approvals, the city application and inspection documents. It also explains how revised approval documents return to the local permit record.

Follow the actual input and documentation instructions. Do not promise that a PDF exported by a design tool is a SolarAPP+ submission or that passing an automated check removes installation inspection.

Final pre-submittal checklist

• Current authority instructions and project scope recorded.
• Submission route and any required outside approvals confirmed.
• Every applicable checklist item has a document reference.
• Address, scope, equipment and ratings agree across the package.
• Layout, electrical diagram and equipment evidence describe the same design.
• Structural assumptions resolved or referred for required review.
• Applicable safety and label requirements documented.
• Required signatures/seals and supporting records included.
• Uploaded documents meet portal requirements and remain legible.
• Revision index identifies one current submission.
• Open questions have an owner; unresolved requirements are not marked complete.

A useful internal correction log records the issue, affected drawing, responsible person, evidence and closure date. Measure your own correction patterns before claiming which error is “most common” or promising a percentage reduction.

Example: managing an equipment substitution

Suppose the inverter model changes after the first submission. This is a hypothetical coordination example, not an approved design. Check its ratings and compatibility, revise affected calculations and the electrical drawing, update the equipment packet and index, and follow the authority’s revision process. Review any utility or automated-submission record affected by the change too.

The objective is one traceable configuration through review, installation and inspection. Keep permit issuance, inspection approval and utility permission to energize as separate milestones. Ask each authority for its current processing expectations; no national approval-time estimate is asserted here.

If evaluating SurgePV’s solar design workflow, bring a real jurisdiction checklist to the demo and check which outputs support your team’s process. Approval responsibility remains with the applicable authorities and qualified project participants.

Frequently asked questions

What drawings belong in a solar permit package?

Use the current AHJ checklist. A conventional plan package commonly documents the site, array layout, electrical one-line, equipment and attachment details, with calculations or additional drawings where required. There is no universal sheet count, and an eligible automated submission can follow a different documentation route.

Does every residential solar project need a PE stamp?

No universal state-by-state table can establish the requirement for a particular project. Verify the applicable professional-practice rules and AHJ instructions for who may prepare, sign or seal each document. Electrical plans and structural calculations can have different requirements.

Does SolarAPP+ replace installation inspection?

No. Check current project eligibility and the participating jurisdiction’s process. Automated review does not remove inspection or any separate local application and outside approvals. Keep the approval document, inspection checklist and applicable supporting records available for inspection.

Must interconnection be submitted before the building permit?

Follow the utility and AHJ instructions for the actual site. Some jurisdictions require an outside-agency approval before permit submission; other processes differ. Track permit issuance, installation inspection and utility permission to energize as separate milestones.

Can a checklist guarantee first-pass approval?

No. A checklist helps expose missing information and inconsistencies, but approval depends on the applicable requirements, the design and the authority’s review. Record unresolved items and obtain the necessary qualified review rather than marking them complete because a template contains a note.
