Solar energy is booming in Texas—and if I could talk face-to-face with someone thinking about adding panels, I’d say: “Welcome to the sunniest savings club in America!”
Texas homeowners are snapping up rooftop systems, and many are deciding on a solar buyback plan—where your excess energy doesn’t go to waste, but instead gets sold back to the grid for bill credits.
One option catching attention is the buyback program from Gexa Energy.
But let’s cut through the fluff:
Is Gexa a smart move for solar users, and how does it stack up against plans from TXU Energy, Reliant, Green Mountain Energy, and others?

What Is the Texas Solar Buyback Plan?
In Texas, homeowners in deregulated areas can choose retail electric providers (REPs) that buy back excess solar energy—typically not at full retail value. This is different from traditional net metering (which isn’t mandated here), as your provider determines the compensation structure.
Understanding Gexa Energy’s Solar Buyback Program
What Is a Solar Buyback Plan?
When your panels produce more power than you need, that extra energy gets sent to the grid—and ideally, you get credits on your bill. These programs help boost your solar return on investment by turning surplus energy into savings.
How Gexa’s Buyback Program Works
If you’re signing up for Gexa’s program, you’ll need a smart meter, TDU interconnection approval, and ownership of your system (leased arrays aren’t eligible). Once connected, Gexa tracks your exported electricity and applies credits to your bill—it’s a bill-offset mechanism, not cash payouts.
Important things to note:
- Credits apply to energy usage only—delivery fees, taxes, and other charges aren’t covered.
- Credits expire at the end of each billing cycle if unused.
- The value is based on the retail rate of your selected plan.
Rate Structures & Plan Types
Gexa offers both flat-rate and time-of-use (ToU) plans:
• Flat-rate: earn a fixed credit per kWh you export.
• ToU: earn more during peak hours—great if your system mirrors peak pricing.
Plans generally run 12–24 months and may include early termination fees.
Tip: always review the Electricity Facts Label (EFL) to understand credit rates and restrictions.
Energy Credits: The Devil’s in the Details
With retail-rate credits, you get real value—but only if you use them. There’s no rollover and no cash refund. This mirrors limitations seen in other programs—here’s a useful article about home energy improvements, including solar installations that can help align production and usage.
Benefits and Drawbacks of Gexa Energy Solar Buyback
Let me walk you through what to expect:
Advantages:
• Lower electric bills when you align your usage with production
• Helps Texas shift toward cleaner energy
• Retail-rate credits generally beat wholesale
• No extra hardware required—your smart meter does the job
Limitations:
• No rollover—unused credits disappear
• No cash payout, even if your system overproduces
• Savings depend on usage alignment
Gexa vs. Other Texas Solar Buyback Programs
| Provider | Credit Type | Credit Rollover | Cash Payout | Contract Length | Notes |
|---|---|---|---|---|---|
| Gexa Energy | Retail (varies) | No | No | 12–24 months | Strong options—but no rollover |
| TXU Energy | Wholesale only | Yes | No | 12–36 months | Lower value but rollover flexibility |
| Reliant | Time-based credit | Sometimes | No | 12–24 months | High peak hour credits, plan dependent |
| Green Mountain Energy | Retail | Yes (up to 12 months) | No | Month-to-month or 12 months | Flexible rollover, higher base rates |
| Ambit | Wholesale | No | No | Varies | Limited availability |
| Just Energy | Retail or fixed | No | No | 12–24 months | Inconsistent, depends on region |
Who’s the Best Fit?
If flexibility matters most—and you produce more energy than you use—Green Mountain Energy may be ideal thanks to retail credits and rollover. But if you’re confident in matching your usage to production, Gexa Energy offers strong value.
Is Solar Buyback Worth It in Texas?
Absolutely. With over 19,000?MW of solar installed, Texas ranks second nationally according to SEIA. Systems typically pay for themselves in 7–10 years, and Zillow Research finds that homes with solar sell for 4.1% more.
And per the Public Utility Commission of Texas, there are more than 40 electricity providers in deregulated markets offering solar-friendly plans—so you’ve got options.
Expert Perspectives
“Solar buyback plans like Gexa’s can help homeowners offset grid usage, but understanding how credits work is crucial.” – Lauren Cook, Energy Policy Analyst
“Texas homeowners need to evaluate buyback rates carefully—some plans look great but offer low compensation for excess solar.” – Mark Davis, Solar Consultant
Case Study: A Houston Homeowner’s Experience
John M., from Houston, installed a 7 kW system with Gexa. His bill fell from $160 to $15 in peak summer—but he “missed out on $30 in unused credits in July” due to no rollover. Still, he calls it a win, if you time your usage well.
