Ambit Energy's Total Solar Buyback plan credits your excess solar exports at a fixed 3.5 cents per kilowatt-hour (as of July 2026), with an import rate near 12.6 to 14.5 cents per kWh, a $9.95 monthly base fee, and a $199 early termination fee. It is a straightforward, no-frills solar plan that works well for households that self-consume most of what they produce, and works poorly for oversized rooftops that push a lot of energy back to the grid. I sell Ambit through VIP Energy Service, and I will walk you through the actual numbers, the plan mechanics, and how it stacks up against TXU, Chariot, Reliant, and Green Mountain so you can decide with clear eyes.

Key takeaways

  • Ambit's current Total Solar Buyback plan pays a fixed 3.5 cents per kWh for solar exports and charges roughly 12.6 to 14.5 cents per kWh for imports (as of July 2026, per plan comparison data from MeterPlan and EnergyBot).
  • It is NOT a 1:1 buyback plan. Retail-match plans like TXU Solar Buyback Match 12 and Green Mountain Renewable Rewards Essential 12 pay the same rate for exports as they charge for imports.
  • The $9.95 monthly base fee and Oncor or CenterPoint TDU delivery charges are NOT offsettable by your solar credits.
  • Ambit Total Solar Buyback is available in Oncor (Dallas-Fort Worth) and CenterPoint (Houston) TDU areas, for solar systems up to 25 kW, and covers export credits up to 110% of your consumption.
  • The plan makes sense if your solar system is right-sized for your usage. If you regularly export more than 30% of production, a retail-match plan like TXU or Green Mountain will keep more money in your pocket.

What is Ambit's solar buyback plan?

Ambit's solar buyback plan is a retail electricity contract for Texas homes with rooftop solar that credits you at a fixed rate for every kilowatt-hour of excess solar you send to the grid. Your solar panels power your home first. When your panels produce more than you use, the surplus flows back through your smart meter, and Ambit posts a credit to your bill at the plan's published export rate.

The mechanic is simple. Your monthly statement shows the kWh you imported from the grid at Ambit's energy rate, plus the fixed base fee, plus the TDU delivery charges from Oncor or CenterPoint. Then Ambit multiplies your exported kWh by the export credit rate and subtracts that amount from your energy charges. If your credit exceeds your energy charges in a given month, the surplus rolls over to the next bill.

This is not net metering in the classic California or Massachusetts sense. Texas is a deregulated ERCOT market and does not require utilities to offer true one-to-one net metering. Each retail electric provider (REP) sets its own buyback rules, its own credit rate, and its own eligibility limits, which is why plan-to-plan comparisons matter so much for solar homeowners here. As MeterPlan notes in its April 2026 market update, no Texas REP currently offers a true statewide 1:1 solar buyback that survives after credits are applied.

Which Ambit plans include solar buyback in 2026?

Ambit currently offers two solar-specific plan families in Texas plus a night-of-use option that some solar owners use as a workaround. Here is what each one does:

Total Solar Buyback 12

Ambit's flagship solar plan is a 12-month fixed-rate contract with a 3.5 cent per kWh export credit (as of July 2026). The import rate on the current EFL is in the 12.6 to 14.5 cent range depending on TDU territory and month of enrollment, per plan snapshots from MeterPlan and EnergyBot. Base fee is $9.95 per month and the early termination fee is $199. Plan details and rates subject to change.

Total Solar Buyback 24

The 24-month version locks in a slightly lower import rate (typically 14.0 cents per kWh versus 14.5 cents on the 12-month plan as of July 2026, per EnergyBot's September 2025 comparison table) with the same 3.5 cent export credit, $9.95 base fee, and $199 ETF. The 24-month term is the play if you expect Texas retail electricity rates to keep drifting up and want to lock in longer.

Free & Clear Nights

Ambit's Free & Clear Nights plan is not marketed as a solar plan, but some solar owners with home batteries use it strategically. Nights are free (typically 9 pm to 7 am), which lets a battery-plus-solar home charge for free overnight and export during the day. The tradeoff is a higher daytime import rate, so it only pencils out for solar-plus-battery homes with heavy nighttime shifting.

For most solar-only Texas homes without a battery, the Total Solar Buyback 12 or 24 is the right Ambit plan.

What is the Ambit solar buyback rate in 2026?

Ambit's current solar buyback rate is a fixed 3.5 cents per kilowatt-hour (as of July 2026, per plan detail from MeterPlan's 2026 Ambit review page). That rate does not float with the ERCOT wholesale market, does not step up seasonally, and does not scale with system size. Every exported kWh earns you 3.5 cents in bill credit.

To put that number in context, EnergyBot's comparison of Texas solar buyback plans lists the current market range from 3.0 cents per kWh (Gexa Solar Export, Amigo Nights Free, David Energy Smart Battery) at the low end, to real-time wholesale rates that can spike above 25 cents per kWh on Chariot's Shine plans during peak-demand hours, to 14.0 cents on TXU's Solar Buyback Match 12 which credits at the same rate as its import price.

Ambit's 3.5 cent export credit is near the bottom of that market range for fixed-rate plans. That is the most important fact in this review.

Does Ambit offer 1:1 solar buyback?

No, Ambit does not offer a 1:1 solar buyback plan. Its Total Solar Buyback plans use a fixed 3.5 cent per kWh export rate (as of July 2026) that is well below the 12.6 to 14.5 cent import rate. The gap between what you pay to import and what you earn to export is typically 9 to 11 cents per kWh on Ambit.

If a true retail-match buyback is your priority, TXU's Solar Buyback Match 12 credits exports at the same rate as its imports (currently around 14.0 cents per kWh both directions per EnergyBot's plan data). Green Mountain's Renewable Rewards Essential 12 also currently prices export credits at 12.8 cents per kWh to match its import rate.

The tradeoff with retail-match plans is that the underlying import rate is often higher than a fixed-rate plan like Ambit, so the math only works if you are pushing enough exports to make the higher import rate worthwhile. That is exactly the modeling I walk through below.

Total Solar Buyback fees and credit rules

Beyond the headline rates, three fee and credit rules materially change what Ambit's Total Solar Buyback actually costs you month to month.

$9.95 monthly base fee is NOT offsettable

Ambit's base fee is a flat $9.95 charged every billing cycle, regardless of your solar exports. Even if your solar credit wipes out your entire energy charge, you still owe the base fee, per Ambit's published plan terms. Over a 12-month contract that is $119.40 in fixed costs that your solar production cannot touch.

TDU delivery charges are NOT offsettable

Your Oncor or CenterPoint delivery charges (transmission, distribution, and other utility line-item charges) are billed through Ambit but are set by your TDU. On Ambit's Total Solar Buyback plan, your export credits reduce only the energy portion of your bill, NOT the delivery portion. This is a critical structural point that MeterPlan calls out explicitly in its Ambit review: on many other Texas solar plans (Direct Energy, Gexa, Reliant, Green Mountain, Chariot) the credit absorbs both energy AND delivery charges, which is real money over 12 months.

Credit rollover but no cash out and no contract-end payout

Ambit does roll over unused solar credits from one billing cycle to the next. But those credits expire at the end of your contract with no cash-out option, and they never convert to a check. If you cancel or switch providers with a $200 solar-credit balance, that balance is gone. Plan your enrollment date and contract end to line up with your production trough (typically December in Texas) so you spend the credits before they expire.

Real bill math: what a 1,500 kWh Texas solar home actually pays

Reviewing a Texas electricity bill for solar import and export charges

The best way to see how Ambit compares to alternatives is to run the numbers on a realistic Texas solar home. Say you are in Oncor territory (Dallas-Fort Worth), your household consumes 1,500 kWh per month, your rooftop solar generates 1,800 kWh in a good production month, you self-consume 1,000 kWh directly (never touching the grid), you import 500 kWh from the grid, and you export 800 kWh back to the grid.

Here is what your bill looks like on Ambit Total Solar Buyback 12 versus TXU Solar Buyback Match 12 versus Chariot Shine 12, using current published plan rates (as of July 2026) and typical Oncor delivery charges of $47 per month for a 1,500 kWh home:

Line item Ambit Total Solar Buyback 12 TXU Solar Buyback Match 12 Chariot Shine 12
Import (500 kWh) $72.50 (500 x 14.5 cents) $70.00 (500 x 14.0 cents) $48.50 (500 x 9.7 cents)
Base fee $9.95 ~$9.95 (varies by plan) $0.00 (Chariot has no base)
TDU delivery (Oncor) $47.00 $47.00 $47.00
Export credit (800 kWh) -$28.00 (800 x 3.5 cents) -$112.00 (800 x 14.0 cents) -$36.00 (800 x avg 4.5 cent ERCOT wholesale)
Monthly total $101.45 $14.95 $59.50

At this export ratio (roughly 53% of production sent to the grid), TXU's retail-match plan saves this household roughly $86 per month versus Ambit, or about $1,033 over the year. Chariot lands in between and depends heavily on ERCOT wholesale prices in any given month.

Now flip the scenario. Say your solar system is right-sized and you self-consume 90% of production, so you import 500 kWh and export only 150 kWh. Rerun the math:

Line item Ambit Total Solar Buyback 12 TXU Solar Buyback Match 12
Import (500 kWh) $72.50 $70.00
Base fee $9.95 ~$9.95
TDU delivery $47.00 $47.00
Export credit (150 kWh) -$5.25 (150 x 3.5 cents) -$21.00 (150 x 14.0 cents)
Monthly total $124.20 $105.95

The gap narrows to about $18 per month, or roughly $220 per year. At smaller export ratios, Ambit becomes competitive because the fixed-rate math punishes you less when you are not exporting much.

The lesson: your export ratio (kWh exported divided by kWh generated) is the single most important variable in choosing a Texas solar buyback plan. Below 20%, Ambit's numbers get respectable. Above 40%, a retail-match plan almost always wins.

Here is a side-by-side comparison of the major Texas solar buyback plans available as of July 2026, drawn from EnergyBot's provider table and MeterPlan's plan-detail pages. Plan details and rates subject to change; confirm current rates on each provider's Electricity Facts Label before enrolling.

Provider Plan Import rate (c/kWh) Export credit rate Base fee Notes
Ambit Energy Total Solar Buyback 12 12.6 to 14.5 Fixed 3.5 c/kWh $9.95/mo Credit offsets energy only, not base or TDU
Ambit Energy Total Solar Buyback 24 ~14.0 Fixed 3.5 c/kWh $9.95/mo Longer term, same credit rules
TXU Energy Solar Buyback Match 12 ~14.0 14.0 c/kWh (1:1) Varies True retail match
Chariot Energy Shine 12 ~9.7 ERCOT wholesale, up to 25 c/kWh None Wholesale-linked, upside + downside
Reliant Energy Solar Payback Plus 12 ~10.9 5.9 c/kWh Varies Mid-range fixed
Green Mountain Renewable Rewards Essential 12 ~12.8 12.8 c/kWh (1:1) Varies Buyback subject to change
Gexa Energy Solar Export 12 ~7.9 3.0 c/kWh Varies Cheapest import, low export
Rhythm Energy Powershift Solar Buyback 12 ~21.9 10.2 c/kWh Varies High import, high credit

None of these plans are objectively the "best." The best plan for you depends on your export ratio, your TDU territory, and whether you value stable fixed rates or want upside on ERCOT wholesale spikes.

Who should choose Ambit's Total Solar Buyback? The Solar Export Fit Framework

I use a simple five-factor check with every Texas solar customer before recommending Ambit. Call it the Solar Export Fit Framework. If you score three or more yeses, Ambit's Total Solar Buyback is a reasonable pick. Two or fewer, and a retail-match or wholesale-linked plan will probably serve you better.

  1. Right-sized system. Your solar array is sized to roughly match annual consumption, not oversized for future EV or pool needs. Your export ratio is under 25% in a typical month.
  2. Stable rate preference. You want a fixed, predictable export credit so your bill math is boring, not a variable rate that swings with ERCOT.
  3. Oncor or CenterPoint TDU. You live in the Dallas-Fort Worth or Houston metro. Ambit Total Solar Buyback is not currently offered in AEP Texas Central, AEP Texas North, or TNMP territories.
  4. 12 to 24 month contract fit. You are comfortable committing for a year or two and are not planning to sell your home or make major solar changes in that window.
  5. Simplicity over maximum yield. You would rather have a plan you understand at a glance than squeeze out an extra $50 per month optimizing against ERCOT wholesale.

If you scored two or fewer, look at TXU Solar Buyback Match 12 (for maximum export credit on a right-sized system), Chariot Shine (for wholesale exposure), or Green Mountain Renewable Rewards Essential (for 1:1 credit with a longer track record).

How to enroll in Ambit solar buyback (5 steps)

Texas neighborhood home with rooftop solar and smart meter connection

If Ambit is the right fit, here is the enrollment path from start to first solar credit on your bill. Give yourself 4 to 8 weeks total for a first-time solar install, or about 2 weeks if you already have Permission to Operate.

  1. Confirm your interconnection status. Your solar system needs an interconnection agreement with your TDU (Oncor or CenterPoint) and Permission to Operate (PTO). Without PTO, no REP can pay you for exports. Your solar installer files this paperwork.
  2. Get your ESID and current EFL. Your Electric Service Identifier (ESID) is on your current electricity bill. Note your current provider, plan name, and contract end date. If you switch mid-contract with another REP, they may charge you an early termination fee.
  3. Compare your options honestly. Use the Solar Export Fit Framework above, run the bill math for your export ratio, and confirm Ambit is genuinely the best fit for your situation before enrolling.
  4. Enroll in Total Solar Buyback 12 or 24. You can enroll directly through Ambit Energy, through a VIP consultant like me, or via a Texas Power to Choose listing. Have your ESID, address, and government ID ready. Read the Electricity Facts Label (EFL) carefully so the import rate, export credit, base fee, and ETF match what you expect.
  5. Confirm meter type and first-bill review. Your smart meter must be set to interval-read mode so your TDU reports exports to Ambit. Check your first bill line by line: import kWh, export kWh, base fee, TDU delivery, and the credit amount. If any line item looks off, call Ambit customer service (or your consultant) inside the 14-day rescission window when you can still switch without penalty.

What happens to unused credits at the end of your contract?

Unused Ambit solar credits expire when your Total Solar Buyback contract ends, with no cash-out and no rollover to a new plan. This is the single biggest gotcha on the plan and it costs Ambit customers real money every year.

Time your contract intentionally. Texas solar production peaks March through September and dips in November through January. If you enroll in the spring, your credits build up during high-production summer months. If your contract ends in October, you will likely have a positive credit balance that Ambit does not refund.

Two practical workarounds. First, when your contract is roughly 60 days from ending, calculate your rolling credit balance and reduce self-consumption strategically (run the pool pump longer, precool the house) to draw the balance down before it evaporates. Second, renew or switch to your next Ambit Total Solar Buyback contract on the day the old one ends. That preserves the credit continuity in some cases per Ambit's stated policy, but confirm with the enrollment rep before assuming.

Ambit Total Solar Buyback: my honest verdict

Ambit Total Solar Buyback is a solid, no-drama solar plan for the right household. It is a bad plan for the wrong household. The 3.5 cent per kWh export credit is well below the market for retail-match plans, and the fact that credits do not offset the base fee or Oncor and CenterPoint TDU delivery charges is a real structural limitation.

That said, it is one of the simpler plans on the Texas market to understand. There is no wholesale price swing, no seasonal step-down, no complicated tier logic. If your solar system is right-sized (export ratio under 25%), you are in Oncor or CenterPoint territory, and you value predictability over optimization, Ambit's Total Solar Buyback 12 or 24 will do what it says on the label.

If your export ratio is over 40%, TXU's Solar Buyback Match 12 or Green Mountain's Renewable Rewards Essential 12 will keep several hundred dollars a year more in your pocket. And if you have a home battery and want to arbitrage ERCOT wholesale prices, Chariot Shine or Octopus Energy's Octo 12 are worth a look.

I run the Solar Export Fit math for anyone who is thinking about signing up, so if you want a second set of eyes on your bill before you enroll, I am happy to help.

Frequently asked questions

Does Ambit have a 1:1 solar buyback plan?

No. Ambit's Total Solar Buyback plans pay a fixed 3.5 cent per kWh export credit versus a 12.6 to 14.5 cent per kWh import rate (as of July 2026). TXU Solar Buyback Match 12 and Green Mountain Renewable Rewards Essential 12 are the two mainstream retail-match (1:1 or near-1:1) alternatives available in Texas.

Can Ambit solar credits offset my base fee or TDU delivery charges?

No. Ambit's export credits reduce only the energy portion of your bill, not the $9.95 base fee and not your Oncor or CenterPoint TDU delivery charges. Several competing plans (Direct Energy, Gexa, Reliant, Green Mountain, Chariot) do let credits offset both energy and delivery, which is a meaningful economic difference on a typical Texas solar bill.

What is the maximum solar system size for Ambit buyback?

Ambit's Total Solar Buyback plan is written for solar systems up to 25 kW, with export credits capped at 110% of your consumption in a billing cycle, per plan comparison data from EnergyBot. If your system is larger than 25 kW or you are a commercial customer, contact Ambit or a VIP consultant to confirm eligibility.

Can I cash out unused Ambit solar credits when I cancel?

No. Ambit solar credits have no cash-out value at any point in the contract, and they expire when the contract ends. Plan your enrollment date and contract end date to align with your annual production trough so you use up any positive credit balance before it evaporates.

Which TDU territories offer Ambit solar buyback?

Oncor (Dallas-Fort Worth) and CenterPoint (Houston) are the two TDU territories where Ambit Total Solar Buyback is currently sold (as of July 2026). Homeowners in AEP Texas Central (Corpus Christi, Rio Grande Valley), AEP Texas North (Abilene), or TNMP (parts of North and East Texas) will need to look at other REPs that serve their utility.

Can I switch buyback plans mid-contract?

You can switch from one Ambit plan to another (for example, from Total Solar Buyback 12 to 24) but the $199 ETF may apply if the switch happens before your contract end date. Confirm the switch terms with Ambit customer service or your consultant before initiating the change so you do not get surprised on your final bill.
