Solar in Texas costs about $2.44 per watt, among the lowest prices in the country, so a typical 9.21 kW system runs about $22,500 in cash. The price is the easy part: your buyback plan, loan fees and hail cover decide what you keep.

What solar costs in Texas in 2026
At $2.44 per watt cash, Texas pricing works out like this. Cooling loads often justify going larger than the typical 9.21 kW. For the national picture, see solar panel costs across the country.
Each figure is the EcoGen Index price ($2.44 per watt) times the size. Prices vary by metro, roof and equipment tier, so treat them as comparison anchors.
Nothing to subtractThe federal residential credit is $0 for systems finished after December 31, 2025, and Texas has no state income tax, so there is no state credit either. The cash price is the real price.
Why Texas solar is cheap, and where money leaks anyway
Two identical Texas systems at identical prices can return very different amounts. The difference lives in the fine print, not the panel price.
+Where money leaks
- Financing dealer feesThe most common way a Texas system quietly becomes a much bigger obligation.
Get the cash price beside the financed total - Buyback assumptionsThe price is fixed; the value of your exports is not. In retail-choice areas your buyback plan can change at renewal.
A savings projection is only as good as its export assumption - Hail and heat in the warranty gapsAsk what the panel warranty says about hail, and whether the production estimate includes heat losses.
A hail deductible can erase the savings - Oversizing for exportsExtra panels still lose money if their output sells at a weak buyback rate. Size to what you use.
−Why the sticker is low
- High volume and competitionEvery major metro has a competitive installer market.
- Easy roofsLarge, newer roofs with simple lines.
- Light permittingLighter than on either coast.
The property-tax quiet win
Texas has no solar tax credit, but it has one benefit with no application window, no funding cap and no expiry date.
Your electric bill goes down and your property tax does not go up. File the exemption with your appraisal district.
Texas ComptrollerTexas has no state income tax, so there is no state solar credit to claim.
Section 25D ended for systems whose installation is completed after December 31, 2025.
Retail choice and municipal utilities price solar differently
Retail-choice areas
Your solar buyback comes from your retail plan, and its terms can change at renewal. Compare plans on Power to Choose.
Austin Energy and CPS Energy
Outside retail choice. Both have run their own solar programs and rebates, which can change your net price and give steadier export terms. Confirm the current offer with the utility.

What a complete Texas quote should show
Hardware prices are similar across the state. Quality risk lives in the installation and the paperwork, so ask:
- What is the cash price, and what is the total I pay if I finance?
- What does the panel warranty say about hail?
- Does the production estimate include heat losses?
- What buyback rate does the savings projection assume, and can my plan change it?
- Where is your crew based, and what does the workmanship warranty cover?
Who should not buy solar in Texas at any price
- Your roof is due for replacement within 10 years. In hail country, doubly so.
- You plan to move within about 5 years. Cheap hardware still needs years to pay back.
- Your quote only works with generous export income. That is a bet on a contract, not a savings plan.

Frequently asked questions
How Much Do Solar Panels Cost in Texas?
Solar panels in Texas cost about $2.44 per watt for a cash purchase: about $15,700 for a 6.45 kW system, $19,500 for 8 kW, and $24,400 for 10 kW. Actual quotes vary by metro, roof, and equipment; per-watt cash price is the unit that makes them comparable.
What Is the Average Cost of Solar Panels in Texas Per Month?
It depends entirely on financing, which is where Texas quotes go wrong. A monthly payment reflects the loan’s term, rate, and dealer fee as much as the system. Get the cash price and the total financed cost side by side before judging any monthly number.
Are Solar Panels Cheaper in Texas Than Other States?
Generally yes. Competitive metro markets, simple roofs, light permitting, and volume keep Texas near the bottom of national per-watt pricing, which is why the state’s solar case survives without income-tax credits.
Is There a Tax Credit for Solar Panels in Texas?
No state income tax credit exists because Texas has no state income tax, and the federal residential credit ended for systems whose installation is completed after December 31, 2025. Texas does exempt the system’s added value from property tax, which protects your tax bill as your home gains equipment.
How Much Does Solar Cost in Austin or San Antonio?
Hardware prices are similar to the rest of the state, but Austin Energy and CPS Energy set their own solar terms and have run local programs that change the net price. Check your utility’s current offers before comparing installer quotes.
Does Cheap Texas Solar Mean Lower Quality?
Not inherently: the same equipment sells nationwide, and Texas prices reflect market structure, not corner-cutting. Quality risk lives in installation and warranty service, which is why crew location, hail terms, and workmanship coverage belong in every comparison.
How we calculate these costs
Cost figures use the EcoGen Solar Cost Index (v2 method): Texas’ standardized installed price per watt, blended from current marketplace data and benchmarked against the national modeled cost. Texas is a flagged row: homeowners here paid more than 20% above the usual gap between quoted and paid prices in Berkeley Lab’s 2026 data, so its figure was re-derived. System size and average cost come from the State Profile, built from EIA consumption data, the NREL production factor and the state residential rate. Real quotes vary by roof, equipment and installer.
