Solar Savings Analysis — Irving, Texas

Electricity Market Structure in Irving

Irving is located within the core of the Oncor Electric Delivery service territory and functions as a competitive retail electricity market under ERCOT jurisdiction. The city's diverse residential mix — from Las Colinas master-planned communities to older central Irving neighborhoods — creates a varied electricity demand profile.

Irving's infrastructure is highly integrated with the ERCOT North Hub settlement zone. The city's concentration of corporate headquarters and data center facilities contributes to high aggregate grid reliability requirements, which helps stabilize local distribution system performance for residential solar owners.

For additional context on Oncor Electric Delivery's role as the transmission and distribution operator in this market, see the Oncor Electric Delivery utility authority node.

Solar Irradiation Context — Irving

Irving, Texas receives an estimated annual average solar irradiation in the range of 4.97 to 5.25 kWh per square meter per day, based on NREL National Solar Radiation Database reference data for the North Texas geographic zone. This translates to approximately 5.1 peak sun hours per day on an annualized basis, representing a moderately high solar resource consistent with the broader Texas solar production environment.

City-level irradiation data is applied in SunScore™ modeling as a primary energy yield input. No ZIP code-level or address-level irradiation claims are made on this page. Actual solar output at any specific property will vary based on roof pitch, azimuth, shading obstructions, and system configuration.

Utility Territory & Delivery Structure — Irving

The city's diverse residential mix — from Las Colinas master-planned communities to older central Irving neighborhoods — creates a varied electricity demand profile.

Oncor Electric Delivery does not set retail electricity prices in the deregulated Texas market. Retail rates are established by competing retail electricity providers (REPs) operating under Public Utility Commission of Texas (PUCT) oversight. The delivery charge component of a retail electricity bill — covering Oncor's transmission and distribution infrastructure — is regulated separately and appears as a line item in monthly billing. Solar savings projections on this platform address the energy supply component of the retail bill, not the regulated delivery charge component. Methodology detail is available at SunScore™ Projection Methodology.

Retail Electricity Baseline — Irving (EIA 2024 Reference Year)

Residential electricity rates for Irving used in SunScore™ modeling are derived from EIA Form 861 2024 reference year data. Competitive market pricing in the Dallas County/Irving area has historically producing rate ranges typical of the broader Oncor territory, with variance driven by retail provider selection and contract type.

All rate references on this page are derived from publicly available EIA Form 861 data for the 2024 reference year and represent historical average figures. They are not real-time rates, guaranteed future rates, or provider-specific quotes. Actual retail electricity prices in Irving vary by retail electricity provider, contract type, and enrollment date. Consumers seeking current rate information should consult the Power to Choose portal maintained by the Public Utility Commission of Texas.

Avoided Cost & Export Compensation Context — Irving

Irving solar economics are modeled using the avoided cost framework, which applies the ERCOT North Hub wholesale marginal price as a proxy for grid-exported energy. This wholesale value is consistently lower than residential retail rates, underlining the importance of system sizing based on localized consumption patterns.

In the ERCOT market structure, the avoided cost concept is central to understanding the economic dynamics of solar energy for Texas homeowners. Solar energy consumed on-site avoids the retail rate, while energy exported to the grid is compensated at or near wholesale-proxy levels — a materially lower value. SunScore™ projections distinguish between self-consumption and export scenarios in the modeled output. A detailed explanation of the avoided cost framework used in this platform is available at Avoided Cost Explained.

Federal Incentive Layer — Irving (ITC 30% Reference)

The federal Investment Tax Credit (ITC) is available to qualifying homeowners in Irving who install eligible solar photovoltaic systems. As of the 2024 reference year, the ITC is structured at 30% of eligible system cost under the Inflation Reduction Act (IRA). This credit is non-refundable, meaning it reduces federal income tax liability but does not generate a direct cash payment if the credit amount exceeds tax liability in the installation year. Unused credit amounts may carry forward to subsequent tax years subject to applicable IRS rules.

The federal ITC is incorporated as an incentive layer input in SunScore™ projected payback and return scenarios. GetSunScore does not provide tax advice. Homeowners should consult a qualified tax professional to assess personal eligibility and ITC application. A detailed explanation of the federal solar tax credit as it applies to Texas homeowners is available at Federal Solar Tax Credit Explained.

Irving homeowners can use the Texas property tax exemption for solar equipment value and claim the 30% federal ITC if eligible. As Irving is in the deregulated ERCOT market, export compensation is non-standard and varies by retail electricity provider.

Modeled Projection Context — Irving

Irving's residential profile is characterized by high-density suburban development. In newer communities like Valley Ranch and Las Colinas, architectural standards and roof orientation are primary factors in solar siting. SunScore™ modeling for these areas accounts for the city's specific irradiation zone while emphasizing that site-level obstructions are not captured in the modeled estimate.

SunScore™ projections for Irving are generated by synthesizing NREL irradiation data for the Irving geographic zone, EIA Form 861 rate baselines for the 2024 reference year, publicly available residential system performance assumptions, and applicable federal and state incentive layer inputs. The output is a modeled estimated savings range expressed as an annual and cumulative scenario over a defined projection horizon.

All SunScore™ projections are non-binding modeled scenarios. They do not constitute financial advice, a solar installation quote, or a guaranteed savings figure. Results will vary based on actual system performance, roof characteristics, shading, consumption patterns, and future retail rate changes. Full methodology documentation, including data sources and modeling assumptions, is available at SunScore™ Projection Methodology, GetSunScore Data Sources, and Modeling Assumptions.

Solar Installation Pathway in Irving

Homeowners in Irving who have reviewed GetSunScore's modeled solar savings projection and wish to proceed with installation evaluation may do so through the standard residential solar qualification and contractor evaluation process.

Homeowners evaluating solar installation in Irving typically proceed through structured qualification and installer evaluation stages, beginning with a property assessment to confirm roof suitability, structural capacity, shading conditions, and utility interconnection eligibility under Oncor Electric Delivery's interconnection standards.

GetSunScore does not install solar systems, endorse specific solar contractors, or recommend providers. Qualified homeowners seeking installation evaluation may consult the installer directory referenced in GetSunScore's partner network documentation.
