Value:Varies

Solar panels, wind turbines, and other related energy equipment are exempt from the state's franchise tax. (In Texas, franchise tax is the same as corporate tax and assesses both income and property together.) Qualifying systems may be used to generate electric power or energy used for heating/cooling. Devices to store or distribute energy are also exempt. Special exemptions apply to solar/wind contractors and businesses which manufacture components for renewable energy.

Texas-New Mexico Power Company - SCORE/CitySmart & Commercial Solutions Market Transformation Programs

Value:Varies

TNMP's SCORE/CitySmart advisory programs cater to schools and cities needing guidance to adopt energy efficient building standards and policies. Once the institution identifies practical solutions and targets, they may be eligible for various incentives to see their ideas realized. The Commercial Solutions program serves commercial customers beyond schools and municipal governments, providing similar financial incentives and management assistance to help them adopting solar energy or other energy efficiency projects.

Texas Gas Service - Residential Energy Efficiency Rebate Program

Value:Varies

Residential Texas Gas Service customers in Austin and Sunset Valley may be entitled to a rebate if they install a new energy-efficient HVAC or water heating system, including solar water heating and HVAC systems. Customers must be on the AUST I/S, SUNV I/S, or ABIA I/S billing plans and rates to qualify. Qualifying systems should meet local, state, and federally-set energy efficiency standards and be installed by a Texas Gas Service certified contractor. Additional information is available from the TGS website or by calling (512) 974-7827.

Renewable Generation Requirement

Value:Varies

Beginning in 1999, the Public Utility Commission of Texas has adopted Renewable Portfolio Standards. Each iteration of the RPS sets a minimum quota for the state's renewable energy investment within certain time frames. Previous RPS standards required the state to invest in 10,000 MW of new renewables by 2025, a standard Texas exceeded in 2009. More specific standards have also been established requiring the state to invest in resources other than wind; however, these standards have not been enforced. Solar, wind, biomass, geothermal, and hydroelectric systems are among renewable sources that go toward RPS goals. Different utility companies throughout the state are entitled to equal shares of the state's investment. Texas's Electric Reliability Council prepares a compliance report each year detailing progress toward current RPS standards. Reports are available from the PUCT website.

Renewable Energy Systems Property Tax Exemption

Value:Varies

The State of Texas allows a 100% property tax exemption on any added value arising from new solar, wind, or biomass energy systems or system components. At present, the exemption only applies to commercial properties. Qualifying systems under the tax code include any device used to produce, store, and distribute energy for on-site consumption, but the devices must be constructed on or after January 1, 2014. Assessors will determine how much may be exempt based on depreciated value under a ten-year useful lifespan. Commercial property owners may claim the exemption by filling out Form 50-123, "Exemption Application for Solar or Wind-Powered Energy Devices", from the Texas revenue department. Additional information can be found on the Texas State Comptroller website.

Oncor Electric Delivery - Residential Solar Program

Value:Varies

Through the Residential Solar Program, Oncor Electric Delivery residential customers who install a new photovoltaic system may be entitled to a rebate. The rebate may appear as a payment directly made to the customer, a credit on energy bills, or a discount from the installing solar contractor. Eligible new systems must use the Oncor grid for electric delivery, be interconnected under a timed agreement, meet all local/state/federal codes, and be installed by an Oncor certified contractor. Existing systems do not qualify. Additional information is available from the Oncor Electric Delivery website.

LoanSTAR Revolving Loan Program

Value:Varies

Since 1989, the state of Texas's LoanSTAR (Saving Taxes and Resources) program has offered low-interest revolving loans to fund energy efficiency improvements at public and certain private facilities. The program has assisted 325 clients and invested $545 million since 1985. Eligible borrowers include state government units, public school districts, public colleges and universities, and nonprofit hospitals. Payments are based on the facility's cost savings by using the new energy systems over a 10-year maximum term. Interest rates vary annually. Eligible projects include on-site renewable energy generation systems such as solar photovoltaics/water heating and small wind turbines. Smaller improvements such as energy-efficient lighting and HVAC may also be covered.

Green Mountain Energy Renewable Rewards Program

Value:Varies

Through the Renewable Rewards program, Green Mountain Energy compensates residential and commercial customers who use renewable energy systems interconnected to the grid. Any excess power beyond the needs of the property can be "sold back" to GME for an avoided-cost rate. Qualifying renewable energy technologies include hydroelectric, wave/tidal, wind, solar, geothermal, and biomass. Renewable Rewards is not a traditional net-metering program. As GME is only a retail provider of electric services, qualifying systems must enter interconnection with an outside distributor on the independent Texas grid. The distributor will install a bidirectional meter to measure how much power is sent back to the grid, reporting the total amount to GME. GME will then credit the customer's account.

Interconnection Standards

Value:Varies

The Texas Public Utility Commission has standardized distributed generation and grid interconnection practices in the state since 1999. Texas does not use tiers to organize operational renewable energy facilities, though no interconnected system may be rated for up to ten megawatts. Systems rated for under 500 kW may be eligible for expedited permit review, while those above one megawatt are required to register as either a self-generator or power generation company. Systems are required to meet certain IEEE standards and have a minimum manufacturer's warranty. Owners may be required to install external disconnect switches or carry liability insurance beyond the warranty requirement.

Required Energy Efficiency Goals

Value:Varies

Texas has adopted an energy efficiency resource standard in lieu of a typical RPS law. Private utilities may set their own annual energy efficiency goals; by law, new goals must continually exceed previous objectives. Uniquely, the standard covers both existing energy efficiency improvements and new renewable energy investment. In lieu of a credit system, compliance is measured through annual Energy Efficiency Plans sent to the state legislature. Each report outlines the utilities' objectives and itemizes applicable investments and real cost savings. Additional information is available from the Public Utility Commission website.

TXU - Commercial Energy Efficiency Program

Value:Varies

Through the GreenBack program, TXU offers rebates to commercial customers for investing in long-term energy efficiency improvements. Successful applicants may use the funding they receive to build new renewable energy systems on their property or apply them to improving existing energy systems. Even simple changes such as switching to LED lights may qualify. Funding is subject to certain eligibility standards and other terms/conditions.

Solar and Wind Energy Business Franchise Tax Exemption

Value:Varies

Beginning with the 1982 tax year, solar and wind energy contractors, retailers, and manufacturers based in Texas may be entitled to franchise ("corporate") tax exemptions. The available exemptions currently do not have ceilings. Under the tax code, wind energy systems and solar photovoltaic, water heating, space heating, and air conditioning systems qualify. All system components, including those for energy collection, transfer, and storage, qualify as well.

Frequently Asked Questions

  • As a general rule, unless there are local limitations, the main limitations to the amount of solar panels you can put on your roof are the available space on your roof, your electricity usage, your providers net metering rules, and the limitations of your house hold electrical system.
  • Based on our research the average price per installed watt is $3.21 in Round Rock. This means for a 10kW system you can expect to pay $32,100 though pricing can vary significantly between installers based on the projects requirements.
  • Based on a Zillow research study from 2019, home with solar panels sell for roughly 4.1% more.
  • To generate the most power, solar panels in the United States should face true south as this generally results in the solar panels receiving the most light each day throughout the course of the year. That said, given that energy prices are often variable throughout the day, your installer may recommend you rotate your panels slightly so that the panels will receive more light at the end of the day when energy prices can be more expensive. That said, for most consumers the positioning of solar panels is highly dependent on your home's roof.
