Do Solar Panels Increase Home Value in Texas?
Texas homeowners pay some of the highest electricity rates in the deregulated ERCOT market, and those rates have climbed steadily since 2020. That reality has turned solar panels from an environmental statement into a financial calculation – one that directly affects what a home is worth when it sells.
So, do solar panels increase home value in Texas? The short answer is yes. Research from the Department of Energy, Zillow, and the National Renewable Energy Laboratory consistently shows that homes with owned solar energy systems sell for more than comparable homes without them. But how much more depends on several Texas-specific factors that most guides overlook.
This guide breaks down exactly how solar affects property value in the Texas market, what the research says about sale price premiums, and the state-level policies that make Texas one of the most favorable states for solar ROI.
How Much Value Do Solar Panels Add to a Texas Home
Multiple peer-reviewed studies and industry reports put a clear number on the solar premium. A Lawrence Berkeley National Laboratory study, funded by the U.S. Department of Energy, found that home buyers consistently pay more for properties with solar photovoltaic systems – roughly $4 per watt of installed capacity. For a standard 8 kW residential system in Texas, that translates to approximately $32,000 in added home value.
Zillow’s research supports a more conservative but still significant figure. Their analysis of millions of home sales found that solar panels add approximately 4.1% to a home’s sale price. On a Texas home valued at $350,000, that is a premium of roughly $14,350.
The National Renewable Energy Laboratory (NREL) reports an even wider range, estimating that homes with solar sell for 4% to 10% more than comparable properties. The variance depends on system size, local electricity rates, and buyer awareness of solar benefits in that market.
A 2024 study covered by EnergySage found that in high-electricity-cost markets, solar systems can add up to $79,000 in property value for larger residential installations. While that upper bound applies to premium markets, it illustrates how closely the value tracks against avoided energy costs.
The consistent takeaway across every major study: solar panels do add value to your house, and the premium is not trivial. It typically recovers a significant portion – and in many cases the entirety – of the original installation cost.
Why Solar Adds More Value in Texas Than Most States
Texas has a unique combination of factors that amplify the value solar panels contribute to a home sale. Understanding these factors matters because they explain why a solar installation in Dallas or Houston may deliver a stronger ROI than the same system in a state with lower electricity costs or less sun exposure.
Deregulated electricity market. Texas operates on the ERCOT grid with a deregulated retail electricity market. Homeowners in deregulated zones choose their electricity provider, and retail rates have been volatile – particularly during peak summer months. Solar systems insulate homeowners from rate fluctuations, and that stability is increasingly attractive to buyers. For a deeper look at what Texas homeowners currently pay, see Suntria’s breakdown of average electric bills in Houston.
Exceptional solar irradiance. Texas averages over 230 sunny days per year statewide, with West Texas and the Hill Country exceeding 300 days. Higher irradiance means higher energy production per installed watt, which directly increases the lifetime savings a buyer inherits with a solar home.
Rising utility costs. The average retail electricity price in Texas has increased roughly 30% over the past five years. As grid electricity becomes more expensive, the present value of a solar system’s future energy production increases proportionally – and appraisers factor that into their valuation.
No state income tax. Texas has no state income tax, which means energy savings from solar represent pure after-tax value. In states with high income taxes, the effective value of energy savings is partially offset. Texas homeowners keep every dollar saved on their electric bill.
Strong population growth. Texas continues to lead the nation in population growth, driving housing demand in markets like Dallas-Fort Worth, Austin, Houston, and San Antonio. More demand for housing means more competition among buyers – and energy-efficient homes with lower operating costs command a premium in competitive markets.
Texas Property Tax Exemption for Solar Energy Systems
One of the most significant and underreported advantages for Texas solar homeowners is the 100% property tax exemption on the added value of a solar energy system.
Under Texas Tax Code Section 11.27, the appraised value that a solar installation adds to a home is fully exempt from property taxation. This means that while solar panels increase your home’s market value, they do not increase your annual property tax bill.
Here is why that matters in practice. Texas has some of the highest property tax rates in the country, with effective rates often exceeding 2% of appraised value. If a solar system adds $30,000 in market value to a home, a 2% property tax rate would normally add $600 per year to the tax bill. The Section 11.27 exemption eliminates that entirely.
To claim the exemption, homeowners file Form 50-123 with their county appraisal district. The form requires basic system details – installation date, system capacity, and installer information. Most appraisal districts process the exemption within one assessment cycle, and it remains in effect for as long as the solar system is installed.
This exemption is a critical distinction from many other states. Some states offer partial exemptions or time-limited exemptions. Texas offers a full, permanent exemption – making the state one of the best in the country for preserving the net financial benefit of a solar installation.
Owned vs. Leased Solar Panels and Resale Impact
Alongside the price premium, research suggests solar homes also spend less time on the market.
Zillow’s analysis found that homes with solar energy systems sold 20% faster than homes without solar, on average. Redfin has reported similar patterns in Sun Belt markets, where high air conditioning costs make energy efficiency a top-of-mind concern for buyers.
In Texas specifically, the speed advantage makes intuitive sense. Summer electricity bills in cities like Dallas and Houston routinely exceed $300 to $400 per month. A buyer evaluating two comparable homes – one with a $250 monthly electricity bill and one with a $50 bill thanks to solar – has a clear financial incentive to choose the solar home, even at a slightly higher purchase price.
The time-on-market advantage is most pronounced in markets with higher-than-average electricity costs and strong buyer awareness of solar benefits. Markets like Dallas-Fort Worth and Houston, where Suntria provides solar panel installation services, consistently show strong demand for energy-efficient properties.
How Appraisers Value Solar in Texas Real Estate Transactions
One of the most persistent gaps in the solar-home-value conversation is how appraisers actually calculate the value solar panels contribute. Most guides stop at citing the Zillow or LBNL studies without explaining the appraisal mechanics that determine what a buyer’s lender will accept.
Texas appraisers use three primary methods to value solar installations, and the method they choose significantly affects the final number.
The Income Approach. This method calculates the present value of the future electricity savings the solar system will produce over its remaining useful life. The appraiser estimates annual energy production, multiplies it by the current retail electricity rate, and discounts the total back to present value. This approach is generally the most favorable for solar homeowners because it captures the full economic benefit of the system.
The Cost Approach. This method values the system based on the depreciated replacement cost of the equipment. The appraiser starts with what it would cost to install an equivalent system today, then subtracts depreciation for age and wear. Because solar panel costs have decreased significantly over the past decade, this method can undervalue older systems even if they are still producing at high capacity.
The Comparable Sales Approach. This method compares the sale prices of solar homes against non-solar homes in the same market. It is the most straightforward but requires sufficient comparable transactions, which can be limited in submarkets where solar penetration is still growing.
The Appraisal Institute developed a tool called PV Value specifically to help appraisers assign consistent values to residential solar systems. PV Value uses system specifications – capacity, age, orientation, tilt, and local electricity rates – to generate a defensible valuation figure. Not all appraisers are trained on PV Value, which is why it is worth requesting a solar-literate appraiser if you are selling a solar home.
The practical implication: if your appraiser uses the cost approach on a five-year-old system, the valuation may come in lower than what the system is actually worth based on its energy output. Requesting an income-based appraisal, or providing the appraiser with PV Value data, can make a meaningful difference in the assessed premium.
Factors That Affect How Much Value Solar Adds
The solar premium is not a fixed number. Several variables determine where a given home falls within the 4% to 10% range.
System age and remaining warranty. Solar panels typically carry 25-year performance warranties. A system with 20 years of warranty remaining is worth significantly more to a buyer than one with five years left. Panel degradation rates average 0.5% to 0.8% per year, so newer systems also produce more energy per installed watt.
System size relative to energy usage. A system that offsets 80% to 100% of a home’s electricity consumption adds more value than one that covers only 30%. Buyers are looking at the net electricity bill, and full-offset systems deliver the most dramatic bill reduction.
Panel and inverter quality. Higher-efficiency panels from recognized manufacturers (such as those used by Suntria’s installation teams) hold their value better than budget equipment. Microinverter systems, which allow panel-level monitoring and optimization, are generally valued higher than string inverter setups.
Roof condition and orientation. Solar panels installed on a south-facing roof in good condition contribute more value than a system on an east- or west-facing roof that may need re-roofing within a few years. If the roof needs replacement, some buyers will discount the solar system’s value because reinstallation costs add to the total expense.
Local utility rate and buyback structure. In deregulated Texas markets, the retail electricity rate varies by provider and plan. Homes in areas with higher rates see larger solar premiums because the avoided cost per kWh is greater. Additionally, some Texas retail electric providers offer buyback programs for excess solar generation, which adds another layer of financial return that appraisers can factor into their valuation.
Battery storage. Homes with solar-plus-battery systems are increasingly valued at a premium above solar-only installations. Battery backup provides energy security during grid outages – a concern that has grown since the 2021 Texas winter storm. While battery storage adds to the installation cost, it also expands the system’s value proposition for buyers who prioritize resilience.

Solar Incentives Still Available for Texas Homeowners in 2026
An important note for homeowners evaluating the investment today: the federal residential solar Investment Tax Credit (ITC) expired on December 31, 2025. Content published before that date may still reference the 30% federal tax credit, but it is no longer available for residential installations. For a complete overview of what remains, see Suntria’s Texas solar incentives guide.
That said, several meaningful incentives remain for Texas homeowners in 2026.
Property tax exemption. As discussed above, the 100% property tax exemption under Texas Tax Code Section 11.27 remains in full effect. This alone saves Texas solar homeowners hundreds to thousands of dollars annually.
Local utility rebates. Some municipal utilities still offer rebates or incentive programs. Austin Energy, CPS Energy (San Antonio), and select cooperatives maintain solar incentive programs that reduce the net installation cost. Availability and amounts vary by utility and change frequently, so it is worth checking current program status before installation.
Retail electricity buyback programs. In the deregulated ERCOT market, several retail electric providers offer solar buyback plans where homeowners receive bill credits for excess electricity exported to the grid. While not true net metering (which Texas does not mandate statewide), these plans can meaningfully reduce the net electricity cost and improve solar ROI.
Sales tax exemption. Texas does not charge sales tax on the purchase of solar energy systems. On a $30,000 installation, the 8.25% sales tax exemption saves approximately $2,475.
Commercial solar incentives. For commercial properties, the Section 48E Investment Tax Credit remains available under the Inflation Reduction Act. Businesses installing solar on commercial properties can still claim significant federal tax benefits, which extends the commercial solar value proposition beyond the residential ITC expiration.
The Bottom Line for Texas Homeowners
The data is consistent and clear: solar panels increase home value in Texas. The premium ranges from 4% to 10% depending on system specifics, and Texas-specific policies – particularly the property tax exemption and sales tax exemption – make the state one of the most favorable markets in the country for solar ROI.
Ownership matters. Owned systems deliver the strongest resale premium, while leased panels introduce complexity that can slow or stall a sale. And the way a system is appraised matters too – requesting an income-based valuation or a solar-experienced appraiser can make a significant difference in the assessed value.
Whether you are considering solar as a long-term energy investment or evaluating how it will affect your home’s resale value, the financial case in Texas is strong – even after the expiration of the federal ITC.

LOWER YOUR ELECTRIC BILL WITH SOLAR
Frequently Asked Questions
Do solar panels increase property taxes in Texas?
No. Texas Tax Code Section 11.27 provides a 100% property tax exemption on the added value from solar energy systems. While solar panels increase your home’s market value, that increase is exempt from property tax assessment. You must file Form 50-123 with your county appraisal district to claim the exemption.
How much do solar panels increase home value in Texas?
Research shows solar homes sell for 4% to 10% more than comparable homes without solar, depending on system size, age, and local market conditions. On a median-value Texas home, that translates to roughly $14,000 to $35,000 in added value. A Lawrence Berkeley National Laboratory study found a premium of approximately $4 per installed watt, which puts a standard 8 kW system at around $32,000 in added value.
Do solar panels hurt the resale value of your home?
Owned solar systems do not hurt resale value – they consistently increase it across every major study. The only scenario where solar can create friction is with leased panels or power purchase agreements, where the buyer must assume the lease or the seller must negotiate a buyout. Owned systems transfer cleanly with the property and add appraised value.
Can a house run 100% on solar in Texas?
Yes. With a properly sized system and a battery storage solution, a Texas home can offset 100% of its electricity consumption. The feasibility depends on the home’s energy usage, available roof space, and whether the homeowner adds battery storage for nighttime and cloudy-day coverage. Many Suntria customers in Houston and Dallas achieve full energy offset with systems sized between 8 kW and 14 kW.
Why is my electric bill still high with solar panels?
Several factors can cause higher-than-expected bills even with solar. The system may be undersized for the home’s consumption, shading from nearby trees or structures may reduce output, or the homeowner’s electricity plan may not include favorable buyback rates for exported energy. System monitoring data can identify production issues, and switching to a solar buyback electricity plan can improve the financial return.
Is the federal solar tax credit still available in 2026?
The federal residential solar Investment Tax Credit (ITC) expired on December 31, 2025. It is no longer available for new residential installations. However, the commercial ITC under Section 48E of the Inflation Reduction Act remains available for business and commercial property installations. Texas homeowners can still benefit from the state property tax exemption, sales tax exemption, local utility rebates, and retail electricity buyback programs.
