Texas Solar Guide 2026

I've spent months untangling Texas's messy solar market — ERCOT deregulation, utility buyback programs, and which REPs actually pay you fairly. Here's what I found.

Texas solar incentives (2026)

Incentive Type Amount Status Notes
Federal ITC (Solar Tax Credit) Federal tax credit 30% of system cost Active Available to all TX homeowners. Expires Dec 2032.
Property Tax Exemption State tax exemption 100% of added solar value Active Solar cannot increase your property tax assessment. Permanent in state law.
Austin Energy Value of Solar Tariff Utility export credit ~$0.097/kWh Active Austin Energy customers only. One of the best solar programs in Texas.
CPS Energy Rebate (San Antonio) Utility rebate $2,500 (for 6 kW system) Active Budget-limited — apply early. San Antonio CPS customers only.
Oncor Solar Buyback (DFW) Utility program Varies by REP REP-dependent Oncor does not offer net metering. Solar buyback rate depends on your retail provider.
ERCOT Market Solar Buyback Market mechanism Varies by REP plan Market-set Retail electric providers set their own buyback rates. Best REPs: Rhythm, Green Mountain.

REP = Retail Electric Provider. Most of Texas operates in the deregulated ERCOT market where REPs compete for customers and set their own solar export rates.

Texas's net metering mess — the real story

Texas has no statewide net metering law. What you receive for excess solar energy depends entirely on your utility or REP — and some pay literally $0 for it. This is the single biggest wildcard in Texas solar economics.

Why Texas is different (and harder)

I'll be honest: Texas solar is more complicated than most states. In the ERCOT deregulated market — covering Dallas, Houston, and most of the state — your retail electric provider decides what they'll pay for your excess generation. Some providers, like Rhythm Energy, pay full retail rate. Others pay pennies or nothing at all. I've seen homeowners with identical systems get vastly different returns depending on which REP they happened to sign with.

This isn't a minor detail — it can swing your payback period by 3+ years.

Best solar buyback REPs in Texas (2026)

If you're in ERCOT territory, your REP choice matters as much as your installer choice:

  • Rhythm Energy Solar Buyback: Full retail rate (~13.5¢/kWh) for excess credits. This is the one I recommend first — straightforward, no games.
  • Green Mountain Energy: Competitive buyback rate, bundled with renewable matching. Good option if you care about the whole clean energy package.
  • Reliant Solar Sellback: Offers credit at varying rates depending on your plan. Read the fine print.
  • TXU Energy: Buyback available in some plans, but rates vary wildly. I've seen TXU customers get great deals and terrible ones — depends entirely on which plan you're on.

Austin and San Antonio: the lucky ones

If you live in Austin or San Antonio, congratulations — you have it much easier. Austin Energy's Value of Solar Tariff pays ~$0.097/kWh for exports with no guesswork. San Antonio's CPS Energy offers rebates plus decent buyback. These municipal utilities operate outside ERCOT's deregulated chaos, and honestly, their solar economics are 20-30% better than the state average.

Why batteries make more sense in Texas than most places

Here's something most solar salespeople won't emphasize: battery storage is a stronger financial case in Texas than in states with good net metering. Why? Because without guaranteed buyback rates, storing your excess solar to use during expensive evening hours captures value you'd otherwise lose. Plus, after Winter Storm Uri knocked out power for millions in 2021, backup capability has real value here that it doesn't in milder climates.

I'm not saying everyone needs a battery — but if your REP pays poorly for exports, the math often works out.


Texas solar install costs (Q1 2026)

System size Gross cost After 30% ITC Annual savings est. Payback (est.)
6 kW (small-avg home) $16,680 $11,676 ~$1,050/yr ~11.1 years
8 kW (average Texas home) $22,240 $15,568 ~$1,400/yr ~11.1 years
10 kW (larger home) $27,800 $19,460 ~$1,750/yr ~11.1 years
12 kW (large home) $33,360 $23,352 ~$2,100/yr ~11.1 years

Savings assume 85% self-consumption with minimal export credit. Austin/San Antonio customers with favourable export programs typically see payback of 8–10 years instead. Your installer should model your specific utility situation.
