Solar Buyback Plans in Texas
Solar buyback plans let Texas homeowners sell surplus solar energy back to their REP for bill credits. With no statewide net metering mandate, buyback rates in 2026 range from 3¢/kWh (fixed) to $5/kWh (real-time wholesale spikes). Ambit Energy offers one of the highest fixed rates — up to 12.5¢/kWh in true 1:1 buyback. This guide compares 12 providers, breaks down 2026 economics after the federal tax credit expired, and shows you how to choose the right plan.
If you’ve invested in solar panels — or you’re considering it — a solar buyback plan determines how much value you get from every kilowatt-hour your system sends back to the grid. In Texas’s deregulated electricity market, there’s no statewide net metering mandate. Instead, individual Retail Electric Providers (REPs) offer solar buyback plans texas homeowners can shop for competitively. Buyback rates in 2026 range from as low as 3 cents per kWh on fixed-credit plans to brief spikes exceeding $5/kWh on real-time wholesale plans. Ambit Energy offers one of the highest fixed rates — up to 12.5 cents per kWh in true 1:1 buyback. This guide covers how texas solar buyback plans work, what they pay, and how to choose one that actually maximizes your solar investment.
What Are Solar Buyback Plans and How Do They Work?
Approximately 85% of Texas homes sit in the deregulated ERCOT market, which means you can choose your REP, according to Solar Reviews. Out of over 100 REPs in Texas, only a handful offer solar buyback plans — programs that give you bill credits for surplus energy your panels export to the grid.
Three main types of solar buyback plans exist in Texas:
Uncapped credit plans — No limit on credit accumulation. Credits roll over indefinitely. These generally save the most money.
Capped credit plans — Credits accumulate to a maximum (for example, Green Mountain caps at $1,000), then any excess generation earns nothing.
Real-time wholesale (RTW) plans — Credits fluctuate with ERCOT market prices every 15 minutes. Potentially lucrative in summer but unpredictable in winter.
A critical detail many homeowners miss: solar credits only offset the energy supply portion of your bill. TDU delivery charges — Oncor at 5.58¢/kWh, CenterPoint at 6.00¢/kWh — still apply on every kilowatt-hour you consume from the grid, regardless of how much you export, according to Quick Electricity.

Solar Buyback Rates and Providers in 2026
The texas solar buyback landscape has shifted significantly. Most REPs have moved away from true 1:1 net metering toward lower fixed rates or volatile real-time wholesale pricing. Here’s how the major providers compare:

Top Octopus Energy solar customers earned an average of $635 per month in August during peak demand, with the top customer bringing in over $900 in credits, according to Quick Electricity. However, RTW credits can drop below 2¢/kWh during mild weather months.

The Real Economics of Solar Buyback in 2026
Here’s what the numbers actually look like for a typical Texas solar homeowner:
System costs: The average 14 kW solar system in Texas costs approximately $30,887 before incentives, according to EnergySage. That’s higher than previous years because the federal 30% Residential Clean Energy Credit expired December 31, 2025. Without the credit, payback periods extend by 3–5 years to approximately 8.73 years — but 25-year savings still reach $80,305, according to EnergySage.
Surplus generation: A typical Texas home with solar exports 20–40% of its generation to the grid as surplus, according to Texas Power Guide. For a system generating 1,200 kWh/month, that’s 240–480 kWh in monthly exports.
Realistic annual credit ranges:
Fixed credit at 3¢/kWh: $86–$173/year
Fixed credit at 12.5¢/kWh (Ambit 1:1): $360–$720/year
RTW plans: $180–$900+/year (highly seasonal, summer-weighted)
Remaining incentives for 2026:
Texas property tax exemption — 100% exemption on solar system appraised value, saving approximately $300–$450/year over the system lifetime, according to Solar Reviews
Oncor residential solar rebate — Up to $9,000 per home (requires solar + battery pairing), according to Quick Electricity. Program closes November 2026 or when budget is depleted.
Third-party ownership (TPO) — Solar leases and PPAs still qualify for the federal credit through 2027

How to Choose the Right Solar Buyback Plan
Not all solar buyback plans are created equal. When shopping for a texas solar buyback plan, evaluate these factors:
Buyback rate vs. retail rate — A high buyback rate means less if the retail rate (what you pay for grid consumption) is also inflated. Compare both numbers.
Credit rollover policy — Do credits roll over month-to-month indefinitely, or do they expire annually? Chariot, Champion, and Octopus offer indefinite rollover.
Monthly fees — Some plans charge $9.95–$19.95 monthly fees that eat into credit value.
Contract length — Longer contracts (24–36 months) may lock you into unfavorable rates as the market shifts.
TDU service area — Your delivery charges differ by TDU. Oncor territory (5.58¢) is cheaper than CenterPoint (6.00¢).
Battery eligibility — Some plans (Tesla Electric, David Energy) specifically reward battery owners who can export stored energy during peak hours.
Cash-out option — Most plans are credit-only. David Energy and Tesla Electric may offer actual cash payouts.
Red flags to watch for: Use-it-or-lose-it credit expiration, low buyback rates paired with high monthly fees, rate riders buried in the EFL (Electricity Facts Label) that increase your cost during peak months, and “promotional” buyback rates that drop after 6 months.
Always read the EFL before signing. Look specifically for: the buyback credit rate, credit expiration terms, monthly service fees, and whether the plan charges different rates for imported vs. exported kWh. Texas net metering rules require these details in the EFL.

The Battery Bridge: When Buyback Isn’t Enough
If 20–40% of your solar generation goes to the grid at 3–6 cents/kWh, you’re selling low and buying high. That gap is why 85–90% of new solar installations in Texas now include battery storage, according to Energyscape Renewables.
A home battery stores surplus solar energy instead of exporting it at low buyback rates — then discharges during expensive peak hours when grid rates are highest. This “battery bridge” approach can capture significantly more value than buyback credits alone, especially for homeowners on plans with low fixed export rates.
Battery arbitrage also pairs well with RTW plans: charge the battery during off-peak (or with solar), then export during $2–$5/kWh spikes. Tesla Electric and David Energy are building their entire business model around this concept.

Step-by-step guide to choosing the right solar buyback plan in Texas.
Getting Started with Solar Buyback in Texas
Ambit Energy’s solar buyback plans offer a true 1:1 ratio at up to 12.5 cents per kWh — meaning every kWh you export earns the same credit as what you pay for grid consumption. Credits roll over indefinitely with no cap.
Ambit’s TLC Pledge (“Try it. Like it. or Change it!”) gives solar homeowners 60 days to test any plan. If it doesn’t fit your generation pattern, switch to a different Ambit plan at no cost — no early termination fee during the trial period.
Before choosing any plan, check your actual usage at Smart Meter Texas to understand your export potential. Then browse solar electricity plans to find the right fit for your home.

Frequently Asked Questions
What is a solar buyback plan in Texas?
A solar buyback plan is an electricity plan from a Texas Retail Electric Provider (REP) that gives you bill credits for surplus energy your solar panels export to the grid. Texas has no statewide net metering law, so each REP sets its own buyback rates and terms. Credits typically offset only the energy supply portion of your bill — TDU delivery charges (5–6 cents/kWh) still apply.
How much can I earn from solar buyback credits?
Annual buyback credits for a typical Texas solar home range from approximately $86 to $900+ per year, depending on system size, export volume, and plan type. Fixed-credit plans at 3 cents/kWh earn less but predictably. Real-time wholesale plans can earn significantly more during summer peak demand but vary widely by season.
Do I need a battery for a solar buyback plan?
No — you can use a solar buyback plan without a battery. However, adding battery storage lets you capture more value from your solar investment by storing surplus energy for personal use during peak rates rather than exporting at lower buyback rates. In 2025–2026, approximately 85–90% of new solar installations in Texas include battery storage.
