Installing rooftop solar panels is a popular way for Texas homeowners to combat high electric bills and reduce grid dependence. With over 230 sunny days a year, Texas residential solar arrays regularly produce more electricity than a home consumes during the middle of the day.

In many states, utilities are required by law to credit you for this excess power at the retail rate (a policy called Net Metering). However, because the Texas retail market is deregulated, there is no state mandate for net metering.

Instead, retail electric providers (REPs) design their own voluntary Solar Buyback Plans. Because buyback terms vary wildly between providers, choosing the wrong plan can significantly reduce your return on investment.

In this guide, we explain how solar buyback plans work in Texas, compare the different payout structures, and outline how to choose the best plan for your system.

Solar Buyback Structure Comparison

Below is an interactive comparison detailing the credit values, rollover rules, caps, and recommended hardware configurations for the primary solar buyback models in Texas:

Texas Solar Buyback Plan Structures

Comparing the mechanics, credit limits, roll-over rules, and recommended system types for each solar buyback model.

Buyback Model	Export Credit Rate	Monthly Credit Cap	Credit Rollover	Best Suited For
1-to-1 Net Metering	Matches your import retail rate (100%)	None (Can offset entire bill)	Yes (Usually rolls month-to-month)	No-battery systems sized to match annual use.
Capped Credit Plan	Fixed rate (often lower than import)	Capped at monthly import total	No (Excess monthly exports forfeited)	Slightly undersized systems that rarely overproduce.
Real-Time Wholesale	Tied to ERCOT spot prices (highly variable)	None	Yes (Rolls over / can cash out)	Smart battery systems designed to export at peak hours.

Detailed Buyback Structures

1. 1-to-1 Net Metering (Flat Credits)

How It Works: The provider credits you the exact same rate for outflows that they charge you for inflows (e.g., 14¢ per kWh imported, 14¢ per kWh exported).
The Catch: These plans often come with high monthly base fees or restrict credits from rolling over to subsequent months.
Best For: Homeowners with systems sized to match their exact usage, or those without batteries.

2. Real-Time Wholesale Spot Pricing

How It Works: The provider credits your exported power based on the immediate real-time wholesale spot price of electricity on the ERCOT grid.
The Catch: During the sunny afternoon when your panels export the most, wholesale prices are often very low (2¢ to 3¢ per kWh). However, during grid emergencies, prices can spike to $9.00 per kWh, rewarding you handsomely.
Best For: Homeowners with smart battery storage who can hold power and export during evening peak price hours.

3. Capped Credit Plans

How It Works: The provider credits exports at a flat rate, but you can only offset up to your total monthly import charge. If you export more than you import in a month, the excess credit is forfeited (you cannot receive a cash refund or build a positive balance).
Best For: Homes with smaller solar arrays that rarely overproduce on a monthly basis.

How to Audit and Choose a Solar Plan

To maximize your solar savings, do not just choose the plan with the highest advertised export rate. Review these contract details carefully:

Avoid Unhedged Minimum Fees: Some buyback plans carry $20 monthly base fees that eat away at your solar credits.
Verify Rollover Policies: Ensure unused credits roll over from spring to the hot summer months when your AC usage spikes.
Compare TDU Pass-Transmission Credits: Check if the export credit covers both the energy charge and TDU delivery charges, or only the bare energy rate.

Price Your Solar Buyback Against Real Production on GetElectricity

Buyback math lives or dies on the split between what you import from the grid and what your panels export — your interval data is the only way to settle it honestly.

GetElectricity connects directly to your Smart Meter Texas data to build your real 12-month usage profile, then simulates hundreds of active plans across Houston, Dallas, Round Rock, and Waco, comparing buyback structures against your actual import and export pattern instead of a generic sunny-day estimate.

Match Your System Size to the Buyback Model

The same solar array earns wildly different returns under each structure, so size the system to the plan — or pick the plan for the system you already have.

Oversized array on a capped credit plan is the worst pairing. Every kWh you export beyond your monthly import total is forfeited. If your panels regularly out-produce your usage, a capped plan converts your extra sunshine into nothing.
A right-sized array belongs on 1-to-1 net metering. When production roughly matches annual consumption, the full retail credit on every exported kWh — with month-to-month rollover — delivers the cleanest math, no battery required.
A battery changes the answer. Under real-time wholesale, the sunny-afternoon export price is often just 2¢ to 3¢ per kWh. Storing that power and exporting during evening peaks — or during rare spikes toward $9.00 per kWh — is where the structure pays off.

Whichever model you choose, confirm the rollover terms before signing: credits banked in mild spring months need to survive into the summer, when your AC turns them into real savings.

Frequently Asked Questions

Does Texas require net metering for rooftop solar?

No. Because the Texas retail electricity market is deregulated, there is no state mandate requiring utilities to credit excess solar power at the retail rate. Instead, retail electric providers design their own voluntary solar buyback plans, and the terms — export rate, credit caps, and rollover rules — vary widely between providers, so choosing the wrong plan can significantly reduce your system's return on investment.

What are the main types of solar buyback plans in Texas?

There are three primary structures. A 1-to-1 plan credits exports at the exact rate you pay for imports, usually with month-to-month rollover — best for no-battery systems sized to annual usage. A capped credit plan pays a flat export rate but only offsets up to your monthly import total, forfeiting any excess. A real-time wholesale plan pays the ERCOT spot price — often just 2¢ to 3¢ per kWh on sunny afternoons, but up to $9.00 per kWh during grid emergencies — making it best for smart battery systems that export at evening peak prices.

What should I check in the fine print before choosing a solar buyback plan?

Look beyond the advertised export rate. Avoid plans with monthly base fees around $20 that eat away at your credits, verify that unused credits roll over from the mild spring months into the high-usage summer, and confirm whether the export credit covers both the energy charge and TDU delivery charges or only the bare energy rate.
