What is Austin Energy's Value of Solar tariff?

Austin Energy's Value of Solar (VOS) tariff is fundamentally different from net metering. Instead of crediting only excess solar exports at a retail rate, the VOS tariff credits ALL solar generation your system produces at a fixed rate — 9.91 cents per kilowatt-hour in 2026 — regardless of whether that energy is used on-site or exported. Austin Energy separately charges you for all electricity you pull from the grid at retail rates. This structure rewards solar production directly rather than netting exports against imports, making it more predictable to model than traditional net metering.

Is there a federal solar tax credit available for Austin homeowners in 2026?

The federal Section 25D residential solar tax credit (30%) expired December 31, 2025 and is no longer available for cash or loan solar purchases in 2026. Solar systems installed before December 31, 2025 qualified for the credit. Texas homeowners can still access the Texas 100% property tax exemption on solar added value and the Texas sales tax exemption on solar equipment and installation labor — both remain active in 2026.

What electrical code does Austin use for solar in 2026?

Austin uses NEC 2020 as the working electrical standard for solar permits in 2026. Texas municipalities adopt electrical codes independently — there is no statewide adoption mandate. NEC 2026 adoption across Texas is being watched but has not been confirmed for Austin as of July 2026. Austin Energy has its own advanced inverter and interconnection requirements under Austin Energy Rule 25 that supplement the NEC.

Does Austin require a PE stamp for residential solar?

Texas has no statewide PE stamp requirement for residential solar. The City of Austin Development Services Department does not require a licensed PE to stamp residential rooftop solar plan sets for standard installations. Commercial projects and systems exceeding 10kW may have additional engineering documentation requirements. Confirm with Austin DSD for the specific project before submission.

How long does an Austin solar permit take?

Austin Development Services offers a streamlined green energy permit process with typical timelines of 5 to 10 business days for standard residential solar. Austin offers same-day in-person permit review for qualifying projects. Austin Energy interconnection and meter upgrade runs on a separate parallel track — interconnection typically takes 2 to 6 weeks depending on system size and grid capacity.

What Texas solar consumer protection laws apply in 2026?

Texas SB 1036 and SB 1697, effective September 2025, require solar retailers and salespeople to register with TDLR (Texas Department of Licensing and Regulation) and establish PUCT-developed consumer information guides for all utilities including Austin Energy. These laws apply to all solar sales in Texas. Verify that any installer quoting your customer is TDLR-registered under the new requirements.

What NEC edition does Texas use for solar permits?

Texas auto-adopts each new NEC edition on September 1 of the publication year. NEC 2023 became the Texas state electrical code on September 1, 2023. Most major Texas AHJs including Houston, Dallas, Austin, Fort Worth, and San Antonio are enforcing NEC 2023. Some smaller jurisdictions may still reference NEC 2020. Verify the adopted edition with your specific AHJ before submission — Texas has no statewide enforcement mechanism, so local adoption varies.

Does Texas have a statewide solar permitting process?

No. Texas has no statewide solar permitting process. Solar installation permits are managed entirely at the local level across 254 counties and hundreds of individual municipalities. Requirements vary dramatically from city to city — Houston, Dallas, Austin, and San Antonio all operate distinct permitting systems with different portals, timelines, and documentation requirements. Some rural Texas counties have minimal requirements; others exceed standard codes.

What is SB 1202 and how does it help Texas solar installers?

Texas SB 1202 allows solar installers to bypass a difficult local AHJ by using a state-approved third-party inspection and permitting pathway. This is particularly valuable in high-friction jurisdictions like Irving, where some installers have avoided projects entirely due to requirements exceeding standard codes. Under SB 1202, a licensed third-party inspector reviews and approves the permit, bypassing the local building department. Permit Design plan sets are built to support the SB 1202 pathway.

What is SB 1036 and how does it affect Texas solar installers?

Texas SB 1036 (Residential Solar Retailer Regulatory Act) established comprehensive regulations for residential solar sales in Texas. Contract provisions took effect September 1, 2025, requiring all solar contracts to display the licensed electrical contractor's name and TDLR license number, and giving homeowners a mandatory five-business-day cancellation window. Full registration with TDLR is required by September 1, 2026. All Texas solar retailers and salespersons must be registered to legally operate after that date.

Do Texas solar permit plan sets require a PE stamp?

Texas has no statewide PE stamp requirement for solar. Requirements are determined by each local AHJ. Houston requires structural and electrical PE stamps for commercial installations and residential systems over 10 kW. Dallas requires PE stamps for most commercial systems and emphasizes sequential review across building, electrical, and fire departments. Austin requires PE stamps for systems over 10 kW. San Antonio requires a city-registered master electrician for electrical permit applications. Gulf Coast installations face additional hurricane-zone structural requirements (130–160 mph wind rating).

How long does solar permitting take in Texas?

The statewide median Texas solar permit timeline is approximately 28 days from application to approval. Austin offers same-day in-person permitting for qualifying complete submissions. San Antonio typically runs 5–10 business days after CPS Energy interconnection approval. Houston processes through the ePlanning portal in 5–15 business days. Dallas uses a sequential review process across multiple departments, typically 10–20 business days. Irving and some North Texas municipalities are known for longer review times — SB 1202 third-party pathway is recommended for high-friction jurisdictions.

What is ERCOT and how does it affect Texas solar interconnection?

ERCOT (Electric Reliability Council of Texas) manages the electric grid for approximately 90% of Texas. Unlike other US states, Texas operates an independent grid not connected to the Eastern or Western Interconnection. In ERCOT territory, customers choose their Retail Electric Provider (REP) for deregulated markets, while Transmission and Distribution Utilities (TDUs) — Oncor, AEP Texas, CenterPoint Energy, TNMP — handle the physical grid and solar interconnection applications. In non-ERCOT territory (El Paso, parts of East Texas), municipal utilities or co-ops manage interconnection directly.

What utilities require interconnection documentation in Texas solar permit plan sets?

Texas solar permit plan sets require interconnection documentation specific to the project's Transmission and Distribution Utility (TDU). Major Texas TDUs include Oncor (Dallas/Fort Worth/West Texas), AEP Texas (West and Coastal Texas), CenterPoint Energy (Houston area), Entergy Texas (Southeast Texas), and TNMP (Northeast Texas). Austin Energy and CPS Energy (San Antonio) are municipal utilities with their own distinct interconnection processes. Each TDU has specific requirements for solar plan sets and interconnection applications.

How does Austin Energy's solar permitting process work?

Austin Energy requires completion of a Distributed Generation Planning Application before the City of Austin will issue a building permit. Austin Energy reviews the interconnection application first — systems meeting specific criteria (typically over 10 kW or on commercial properties) require utility approval before the city permit process begins. Once Austin Energy approves, the City of Austin offers same-day in-person permitting for qualifying projects with complete, PE-stamped documentation. Austin Energy also offers a Value of Solar tariff at 9.91¢/kWh plus a $2,500 rebate for qualifying residential systems.

What are Texas wind load requirements for solar permit plan sets?

Wind load requirements for Texas solar permit plan sets vary significantly by location. Gulf Coast installations (Houston, Corpus Christi, Galveston area) require hurricane-zone engineering with wind speed ratings of 130–160 mph per ASCE 7-22. Inland Texas installations (Dallas, Austin, San Antonio) require standard ASCE 7-22 wind load calculations accounting for severe thunderstorm and tornado exposure. West Texas installations face high wind exposure from open terrain. Structural calculations addressing the specific local wind exposure category must be included in every Texas solar permit plan set.

What is the Texas property tax exemption for solar?

Texas provides a 100% property tax exemption for the added value of solar energy systems. This means the appraised value of a Texas property does not increase due to the installation of a solar PV system, regardless of system size or value. On a $23,500 solar system, this saves Texas homeowners $9,500–$13,000 in property taxes over a 25-year system life. This exemption applies statewide and does not require AHJ approval — it's automatic once the system is installed.

How long does it take to get a Texas solar permit plan set from Permit Design?

Permit Design delivers Texas solar permit plan sets within 24–48 hours of receiving your project details. Every Texas plan set is built to the NEC edition adopted by your specific AHJ (NEC 2023 for most major cities), formatted to your city's submittal requirements, and includes TDU-specific interconnection documentation. Rush same-day delivery is available. If your Texas AHJ requests revisions, we handle them at no extra charge — including the SB 1202 third-party pathway if required.

The Austin Energy Difference

Austin Energy's Value of Solar Is Not Net Metering. It Credits ALL Generation — Not Just What You Export. Most Solar Proposals in Austin Get This Wrong.

In most of California and in other Texas cities, solar economics depend on what you export to the grid. Austin Energy is different. The Value of Solar (VOS) tariff credits every kilowatt-hour your system generates — whether it's consumed on-site or exported — at a fixed rate. Austin Energy then charges you separately for every kilowatt-hour you pull from the grid at retail rates. Understanding this structure is essential to sizing Austin solar correctly.

9.91¢ Per kWh · ALL generation · 2026 rate

Austin Energy Value of Solar Tariff — How It Actually Works

Your solar meter measures total kilowatt-hours generated — not net exports. Austin Energy credits that total at 9.91¢/kWh. Separately, your service meter measures all grid imports, charged at retail (~12¢/kWh). You pay retail for everything you pull; you get 9.91¢ for everything your panels produce, regardless of self-consumption. This is not net metering. Austin Energy requires a dedicated production meter alongside the service meter, which affects plan set format and interconnection application.

⚠️ Austin Energy requires advanced inverter settings under Rule 25. Inverters must support volt-VAR optimization, volt-Watt response, and frequency-watt response modes. Not all inverter firmware versions meet this requirement out of the box. Permit Design confirms inverter model and firmware compliance with Austin Energy Rule 25 before submitting interconnection documentation.

Quoting Austin Energy as Net Metering Produces Wrong Customer Expectations

National solar proposal tools model net metering — credits only for excess exports at retail. Austin Energy's VOS credits ALL generation at 9.91¢/kWh. An Austin customer quoted on a net metering model will see different bill savings than projected — and you'll explain the discrepancy. We format plan sets and interconnection documentation for Austin Energy VOS specifically.

💰

The Federal Solar Tax Credit Expired December 31, 2025 — Austin Customers Need to Know

The federal Section 25D credit (30%) expired December 31, 2025 — not renewed. For 2026 installations, there is no federal tax credit. Texas still has a 100% property tax exemption on solar added value and a sales tax exemption on solar equipment. Austin Energy's $2,500 rebate may still be available depending on program funding.

📐

Austin Energy Rule 25 Requires Advanced Inverter Settings That Many Out-of-State Firms Miss

Austin Energy Rule 25 requires inverters to support volt-VAR, volt-Watt, and frequency-watt response modes. An interconnection application with a non-compliant inverter gets rejected — and firmware updates can take weeks. We check inverter model and firmware compatibility before building the plan set.

Austin Solar Market — 2026

Four Things Shaping Austin Solar Right Now.

9.91¢

Austin Energy VOS — Pays on ALL Generation, Not Just Exports

Austin Energy's VOS tariff pays 9.91¢/kWh on all generation in 2026. Unlike net metering — which only credits excess exports — VOS credits every panel-generated kilowatt-hour. The key planning question for Austin is annual generation vs retail cost avoidance — not export volume.

Federal 25D Credit — Expired December 31, 2025

The federal Section 25D credit is gone for 2026 — expired December 31, 2025. The conversation shifts to Texas incentives: 100% property tax exemption on solar added value, sales tax exemption on equipment and labor, and Austin Energy's $2,500 rebate where available.

100%

Texas Property Tax Exemption on Solar Added Value — Active in 2026

Texas exempts 100% of solar added home value from property taxes — permanent and uncapped. A system adding $15,000 to assessed value generates zero additional property tax. Combined with the sales tax exemption on equipment and labor, Texas maintains strong solar economics even without the federal credit.

Rule 25

Austin Energy Advanced Inverter Requirement — Stricter Than Other Texas Utilities

Austin Energy Rule 25 requires volt-VAR optimization, volt-Watt response, and frequency-watt response capability. Most modern inverters support these modes, but firmware version matters — some models need updates. Permit Design confirms compatibility before submitting Austin Energy interconnection documentation.

FAQ

Questions Austin Installers Ask Us

Austin Energy's VOS tariff credits every kilowatt-hour your solar system generates at 9.91¢/kWh in 2026 — regardless of on-site consumption or export. Austin Energy meters total generation through a dedicated production meter and applies the VOS rate to that total. Separately, retail rates (~12¢/kWh) apply to all grid imports. This is not net metering — generation and consumption are metered independently. Size for maximum generation, not minimum export.

No. The Section 25D credit expired December 31, 2025 — not available for 2026 installations. Texas incentives remain: 100% property tax exemption on solar added value (permanent), sales tax exemption on equipment and labor, and Austin Energy's $2,500 rebate where funding remains.

Austin Energy Rule 25 requires inverters to support volt-VAR optimization, volt-Watt response, and frequency-watt response — IEEE 1547-2018 Category B requirements. Most modern inverters support these modes, but the firmware must be current. An inverter that can't document Rule 25 compliance gets the interconnection application rejected. We confirm model and firmware before building.

Austin uses NEC 2020 as the working electrical standard for solar permits in 2026. Texas municipalities adopt electrical codes independently — there's no statewide mandate. Austin has historically been progressive on building codes, but NEC 2026 adoption had not been confirmed as of July 2026. All Permit Design Austin plan sets reference NEC 2020 Article 690 for solar PV and Article 706 for battery storage.

Austin Energy historically offered a $2,500 residential solar rebate (reduced from $3,000 in prior years). Rebate availability depends on program funding allocation — confirm current availability with Austin Energy before quoting customers. Austin Energy's rebate is separate from the VOS tariff and Texas state incentives. Commercial systems have separate incentive structures through Austin Energy's Power Partner program.

All of it — City of Austin, Travis County, Round Rock, Cedar Park, Pflugerville, Manor, and all surrounding cities. Note that some outer Travis County and Williamson County addresses are served by Oncor or Pedernales Electric Cooperative (PEC) rather than Austin Energy — different utilities, different interconnection processes, and different plan set formats. We confirm the utility and AHJ for every address before building.

Most Austin residential plan sets ship in 24 to 48 hours. Battery permit plans same day. Commercial and complex projects: 3 to 5 business days. Rush available on request.
