Solar panel cost in Texas (2026)

In 2026, a typical Texas homeowner pays around $2.60 per watt for a fully installed solar system, putting a common 8 kW system at roughly $20,800 before rebates. The 30% federal residential solar tax credit expired on December 31, 2025, so the price you’re quoted is now essentially what you pay out of pocket.

What solar costs in Texas right now

The statewide average of $2.60/watt covers panels, inverter, racking, wiring, labor, and permit fees. Quotes vary: high-volume national installers may come in near $2.30/watt, while smaller regional contractors can run $3.00/watt or more based on overhead and equipment preferences. Collect at least three itemized quotes and compare them line by line.

Most Texas homes land on systems between 6 kW and 14 kW. Divide your average monthly kilowatt-hour usage by about 130 to estimate system size in kilowatts — that monthly kWh figure is on your electricity bill.

System size	Gross estimated cost	Monthly output estimate*
6 kW	$15,600	~954 kWh
8 kW	$20,800	~1,272 kWh
10 kW	$26,000	~1,590 kWh
12 kW	$31,200	~1,908 kWh
14 kW	$36,400	~2,226 kWh

*Estimated using 5.3 peak sun hours per day × system size × 30 days. Real-world production runs 15–20% lower due to heat losses, wiring losses, and inverter efficiency.

Subtract any applicable utility rebate from the gross cost to reach your actual out-of-pocket figure. There is no federal tax credit to subtract this year.

Why Texas sun and electricity rates shape the math

Texas averages 5.3 peak sun hours per day — above most of the Midwest and Northeast — meaning more kilowatt-hours generated per installed watt and a faster payback. The state’s average retail electricity rate is 15.3 cents per kWh. On a time-of-use plan with steep peak pricing, solar’s effective value per kWh climbs higher still.

Those two figures — 5.3 sun hours and 15.3¢/kWh — are why Texas consistently ranks among the stronger solar markets despite having no statewide net metering mandate. A state with the same rate but weaker sun would look meaningfully different.

What drives your specific quote higher or lower

Equipment tier is the biggest variable after system size. Premium panels from Panasonic or REC carry stronger efficiency ratings and longer warranties. Mid-tier options from Q CELLS or Canadian Solar hit a practical sweet spot for homeowners with adequate roof space. If your roof is small or partially shaded, higher-efficiency panels can fit more production into less area and may justify the premium.

Inverter type matters with shading. String inverters cost least. Microinverters (Enphase) or DC optimizers (SolarEdge) handle partial shading and multiple roof orientations better but add $500–$2,000 or more to the total.

Roof condition can add cost. A deteriorating roof under a 25-year panel warranty needs attention before installation — most installers flag this during the site assessment.

Battery storage runs roughly $10,000–$15,000 installed for a single-battery system. After Winter Storm Uri, many Texas homeowners weigh backup power against criteria beyond simple financial return.

Labor and permitting vary by location. Houston, Dallas, and Austin have established permitting pipelines. Rural installs can involve longer timelines and travel charges from contractors based in larger metros.

The federal credit is gone — what you actually get in 2026

The 30% federal residential solar tax credit under IRC §25D expired on December 31, 2025, as part of the One Big Beautiful Bill Act. For any system installed in 2026, the federal credit is $0. If an installer or website still lists a “30% federal tax credit,” the information is out of date. Confirm your situation with a licensed CPA.

One exception: if you lease solar panels or sign a Power Purchase Agreement (PPA), the company that owns the equipment may still claim the commercial clean energy credit (§48E), available to businesses. Some installers pass part of that benefit through as a lower monthly lease payment or reduced PPA rate per kWh. When comparing buying versus leasing, ask your installer how their §48E eligibility factors into the price they’re offering.

What Texas does offer:

• 100% property-tax exemption on added home value. Texas law exempts the full appraised value added by a solar installation from property taxes. On a system that adds $20,000 to your assessed value, that benefit accumulates across the system’s lifespan.
• Local utility rebates. Austin Energy still offers a $2,500 residential rebate; CPS Energy’s residential solar rebate ended in 2022 and has not returned. Other co-ops occasionally run programs. Call your utility directly — don’t count on a rebate before confirming it exists.
• No state income tax. No personal income tax means no state solar credit, but also no state tax on savings from generating your own electricity.

Net metering in Texas: your utility decides

Texas has no statewide net metering mandate. What you receive for solar energy you export to the grid depends entirely on your utility or, in the deregulated parts of the state, your retail electricity provider.

Some providers credit exports at roughly the retail rate — around 15.3¢/kWh. Others pay a wholesale rate, often 3–6¢/kWh. A few offer nothing. Austin Energy uses a value-of-solar tariff with its own calculation methodology; CPS Energy has a separate structure. The gap between a strong export rate and a weak one can shift payback by several years.

Call your utility before buying and ask: “What rate will I receive per kilowatt-hour I export to the grid?” Get the answer in writing, then model your savings with that number. The solar savings calculator lets you enter your actual utility and usage figures rather than relying on a generic estimate.

A worked example: 10 kW system in central Texas

In the San Antonio area, with average monthly usage of 1,400 kWh and a 10 kW system at $2.60/watt:

• Gross cost: $26,000
• Federal tax credit (2026): $0
• CPS Energy rebate: None — CPS ended its residential solar rebate in 2022 (exports credited at ~2¢/kWh)
• Property tax impact: $0 in additional annual property tax on the added home value

A 10 kW system in central Texas produces roughly 1,590 kWh per month under ideal conditions, or around 1,270–1,350 kWh after real-world losses — nearly enough to cover the 1,400 kWh of monthly usage, with the balance depending on what CPS Energy credits for exports.

At 15.3¢/kWh, offsetting 1,300 kWh per month saves roughly $199 per month, or around $2,388 per year. On a $26,000 gross cost with no rebate applied, that’s a simple payback of about 11 years. Texas electricity rates have historically trended upward, which improves long-term economics. Plug your real numbers into the calculator above for a figure that reflects your actual situation.

How to get an honest quote

Request itemized written quotes from at least three installers. Each quote should list the panel brand and model, system size in kilowatts, inverter type, projected annual kWh production, and a line-by-line cost breakdown. If a contractor won’t provide that detail, move on.

Ask every installer:

• What production guarantee do you offer, and is it in the contract?
• Who handles the utility interconnection paperwork?
• What’s your workmanship warranty on roof penetrations?
• How does my utility credit solar exports, and does your system design account for that?

Verify licensing with the Texas Department of Licensing and Regulation (TDLR). NABCEP-certified installers have passed a nationally recognized technical competency exam — a reasonable baseline for quality.
