Quick answer
Plano permits residential solar as a photovoltaic installation, with its own $150.00 line in the adopted fee schedule. The City publishes a Solar Panel PV Checklist that must be signed and submitted with the plans and application, calling for inverter, module and racking manufacturer sheets in duplicate, a site plan showing modules, inverters, combiner boxes, all AC and DC disconnects, the utility disconnect, meters and the service panel board, and one-line or three-line diagrams. If the equipment pushes the roof load assembly past 10 psf, a structural load assessment letter from a State of Texas licensed engineer is required. The wiring itself falls under the Electrical Code permit requirement in Chapter 6, Section 6-351.

How to apply in Plano
A rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.
What most solar permit applications include:
- Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
- The plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
- Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
- The site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
- The one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
- Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
- Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit
Inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.
- Where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
- The inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
- PV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
- Bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
- At the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
- Utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Plano permit portal or by phone at 972-941-7140.

- Under Texas law (Tex. Occupations Code 1305.003(a)(6), 1301.051; Tex. Local Government Code 233.157(c)): Texas licenses individual construction trades rather than general contractors, so no state statute requires a license to act as your own general contractor on your own house. For electrical work, the state licensing law does not apply to work performed in or on a dwelling by a person who owns and resides in it, but only where no municipal ordinance specifically regulates that work, so city electrical licensing and permit rules still control inside city limits (Occupations Code 1305.003(a)(6)). For plumbing, a property owner does not need a state license to perform plumbing in the owner's homestead (Occupations Code 1301.051). In opt-in counties' unincorporated areas, an individual who builds their own house or acts as their own contractor is exempt from the Class C misdemeanor penalty for inspection notice failures if they intend to use the home as their primary residence (Local Government Code 233.157(c)). None of these exemptions waive local permit or inspection requirements where they apply. Confirm how Plano applies this before you apply.
