Net metering in Dallas

ERCOT deregulated market: Oncor Electric Delivery is the transmission and distribution utility. Oncor does not sell retail electricity or administer buyback credits. Solar customers choose a Retail Electric Provider (REP). Critical Dallas advantage: TXU Energy Solar Buyback Match 36 is available exclusively in Oncor territory and credits exported solar at the full retail rate - effectively 1:1 net metering, the best solar buyback value in Texas. Also available: Green Mountain Renewable Rewards 36 (retail rate match); Shell Energy Buyback Plan (7.0 cents/kWh, lower than retail-match plans). Oncor handles interconnection (typically 10 to 20 business days for residential systems under 10 kW DC) and installs a bi-directional meter at no charge. Maximum residential interconnection system size: 15 kW DC.

Why Dallas homeowners are moving now

After the January 2025 wildfires, battery storage became a priority

Dallas-Fort Worth is the fastest-growing metro in the U.S. by population. The suburbs of Plano, Frisco, McKinney, Allen, and Southlake are primary solar adoption hotspots - newer construction, high household income, large south-facing roofs, and HOA-governed communities that have become more solar-friendly under Texas HOA legislation. The defining solar advantage in Dallas over Houston is Oncor territory access to TXU Energy's 1:1 retail-match solar buyback, which credits every exported kWh at the full retail rate rather than the 7 to 8.5 cents available in CenterPoint (Houston) territory. Winter Storm Uri (February 2021) knocked out power across DFW for days and remains a major driver of battery backup adoption in the metro.

Illustrative example

What does a typical Dallas solar system actually cost and save?

Zero federal residential credit applied (Section 25D expired December 31, 2025). Figures are estimates based on market data as of 2026-06-29. Your numbers depend on your roof, your utility, and your bill.

System inputs

System size: 10 kW
Gross cost ($2.7/W): $27,000
Federal residential credit: $0 (expired Dec 31, 2025)
TX property tax exemption (100% of added value, Form 50-123): Applied
TX sales tax exemption on equipment (~8.25%): Applied
Estimated net cost: $27,000

Estimated outcomes

Annual savings range: $1,800 to $2,700
Estimated payback: 10 years

A 10 kW system in Dallas costs approximately $25,500 to $28,500 gross. Zero federal residential credit applies - Section 25D expired December 31, 2025. The Texas property tax exemption and sales tax exemption reduce effective cost but do not reduce the gross purchase price. At 5.4 peak sun hours and 15.1 cents/kWh retail, a 10 kW system produces roughly 15,500 to 16,500 kWh per year. On TXU Energy's retail-match plan, exported kWh earn the same as you pay to consume - making Dallas the best net-metering analog in Texas. Add the Oncor battery rebate (up to $9,000 with battery storage pairing) and the payback improves further. Estimated payback of 10 years does not include the Oncor rebate; with battery and rebate, payback on the solar component can improve by 1 to 2 years.

For business owners and property managers

Commercial Solar in Dallas

Dallas's commercial real estate boom and Oncor territory give businesses access to 1:1 retail-rate solar buyback and the Oncor commercial rebate structure. Businesses and nonprofits can still capture the 30% Section 48E investment tax credit if construction starts before July 4, 2026. DFW's 5.4 peak sun hours and the metro's strong industrial and office rooftop inventory make commercial solar ROI compelling in this market.

See commercial solar options

Commercial solar projects must begin construction by July 4, 2026 to qualify for the 30 percent Section 48E federal tax credit. After that date, the system must be placed in service by December 31, 2027.

Dallas solar questions

What Dallas homeowners ask

City-specific answers. Every number references your utility and your permit office.

What makes Dallas solar buyback rates different from Houston?

Dallas is in Oncor Electric Delivery territory. TXU Energy's Solar Buyback Match 36 plan is available exclusively to Oncor customers and credits every kilowatt-hour you export at the full retail rate - effectively 1:1 net metering. Houston customers in CenterPoint territory cannot access this plan. The best buyback rate available in Houston is 8.5 cents per kWh; Dallas customers on TXU's plan earn the full retail rate of approximately 15.1 cents per kWh.

Is there an Oncor battery rebate for Dallas solar customers?

Yes. Oncor's Take a Load Off Texas program offers up to $9,000 for qualifying solar plus battery systems: $5,000 for solar and $4,000 for battery storage. Battery pairing with a minimum of 5 kWh usable capacity is required. The program runs February through November or until funding is depleted. Verify availability at oncor.com before signing your installation contract.

Is there a federal solar tax credit in 2026?

No. The Section 25D residential federal tax credit expired December 31, 2025. Texas has no state income tax. Key incentives for Dallas homeowners are the Oncor battery rebate (up to $9,000 with battery), the 100% property tax exemption (file Form 50-123 with Dallas County Appraisal District), and the Texas sales tax exemption on solar equipment.

How long does solar permitting take in Dallas?

The City of Dallas Sustainable Development and Construction Department processes residential solar permits in approximately 5 to 10 business days through the online portal. Dallas does not use SolarAPP+. After permit issuance, Oncor interconnection typically adds 2 to 4 weeks. Total contract-to-energization: 6 to 10 weeks.

Which Dallas neighborhoods have the most solar installations?

Plano, Frisco, McKinney, and Southlake have the highest solar adoption in the DFW metro - newer construction, larger lots, and south-facing roofs make these suburbs the primary growth areas. Lakewood and Preston Hollow within Dallas city limits also show significant residential solar activity. Allen, Flower Mound, and Colleyville are among the fast-growing suburban areas where solar adoption is accelerating.
