Texas Solar Buyback Plans Compared: Finding the Best Deal for Your Solar Panels

What Are Solar Buyback Plans and Why Do They Matter

A solar buyback plan is an electricity plan that credits you for the excess energy your solar panels send back to the grid. When your panels produce more electricity than your home is using — typically during peak afternoon hours — that surplus flows into the grid and your Retail Electric Provider (REP) gives you a credit for it.

The buyback plan you choose is arguably the single most important financial decision you make after installing solar panels. Two identical homes with identical solar systems on different buyback plans can see dramatically different savings. One homeowner might reduce their annual electricity costs by 80%, while their neighbor with a worse plan saves only 40%.

In the deregulated Texas market, you have the freedom to choose from dozens of REPs and plans. That freedom is powerful, but it also means you need to understand the differences between plan types to avoid leaving money on the table.

Types of Solar Buyback Plans in Texas

Solar buyback plans fall into three main categories, and the differences between them directly impact your bottom line:

1:1 Buyback Plans (Full Net Metering Credit) are the best option for most solar homeowners. With a 1:1 plan, every kilowatt-hour you export to the grid earns a credit equal to your consumption rate. If you pay 14 cents per kWh for energy you use, you also earn 14 cents for every kWh you send back. This effectively lets you use the grid as a free battery — storing energy during the day and drawing it back at night at no net cost.

Partial Buyback Plans offer a lower credit rate for exported energy than what you pay for consumption. A common structure might charge you 15 cents per kWh for usage but only credit you 7 to 10 cents per kWh for exports. While these plans can still save you money, the gap between your buy and sell rates means you capture less value from your solar production.

Flat-Rate Buyback Plans pay a fixed amount for all exported energy regardless of your consumption rate. These might offer a flat 8 or 9 cents per kWh for exports regardless of time of day or season. They can be competitive in certain situations but typically underperform 1:1 plans for homeowners with well-sized systems.

Key Factors When Comparing Plans

Looking only at the advertised buyback rate is a mistake that costs many solar homeowners hundreds of dollars per year. A thorough comparison should consider several factors:

Buyback rate versus consumption rate is the most important metric. Calculate the ratio — a plan charging 14 cents for consumption and crediting 14 cents for exports gives you a 1:1 ratio. A plan charging 16 cents but crediting 8 cents gives you only a 1:2 ratio, meaning your exports are worth half as much. Understanding how these charges appear on your bill helps you verify you are being credited correctly.

Base charges and minimum fees can significantly erode your savings. Some plans with attractive buyback rates compensate with higher monthly base charges of $15 to $25. If your solar system offsets most of your energy usage, these fixed charges become a larger percentage of your total bill.

Contract length and early termination fees matter because the solar market evolves quickly. Locking into a 24-month contract might seem safe, but if better plans emerge in 6 months, you could be stuck. Shorter contracts or plans with low termination fees offer more flexibility.

TDU passthrough structure affects how delivery charges are calculated. Some plans bundle TDU charges into the energy rate, while others pass them through separately. For solar customers, passthrough plans are generally more transparent and often more favorable because you can clearly see what you are paying for delivery versus energy.

The Texas Advantage: You Can Switch REPs

One of the most powerful tools available to Texas solar homeowners is the ability to switch REPs without any equipment changes. Your solar panels, inverter, and meter stay exactly the same. Only your billing relationship changes.

Switching typically takes 1 to 2 billing cycles and involves no service interruption. Your TDU — Oncor, CenterPoint, AEP, or TNMP — remains your delivery provider regardless of which REP you choose. The physical infrastructure does not change; only the company that bills you for energy does.

This means if you discover that your current plan undervalues your solar production, you can shop for a better deal and switch with minimal friction. Many solar homeowners find that their original REP's solar plan is not competitive once they compare it against specialized solar buyback offerings from other providers. Homeowners in Dallas, Houston, and Fort Worth have particularly strong options thanks to the concentration of REPs competing in those markets.

Red Flags to Watch For in Solar Plans

Not every plan marketed as "solar-friendly" actually delivers good value. Watch for these warning signs:

Plans that cap buyback credits limit the total dollar amount or kWh volume you can earn in credits each month. Once you hit the cap, additional exports earn nothing. For a well-producing system, these caps can eliminate a significant portion of your potential savings during peak production months.

Time-of-use restrictions on buyback credits mean you earn less for energy exported during off-peak hours. Since solar production peaks during midday, this usually works in your favor, but some plans define "peak" narrowly and discount afternoon exports.

Unusually high base charges sometimes accompany attractive-sounding buyback rates. A plan offering 1:1 buyback but charging a $25 monthly base fee may cost you more annually than a partial buyback plan with a $5 base charge, depending on your production and consumption patterns.

Rollover policies determine what happens to excess credits at the end of a billing cycle. Some plans roll credits forward month to month, while others reset your balance periodically. Plans that pay out credits in cash at a reduced rate can also diminish your effective savings.

How Batteries Interact with Buyback Plans

Battery storage changes the calculus of buyback plan selection in important ways. Without a battery, you must export excess daytime production and then buy energy back from the grid at night. Even with a 1:1 buyback, TDU delivery charges still apply to the energy you draw from the grid after sunset.

With a battery, you can store excess production and use it during evening and nighttime hours, bypassing grid delivery charges entirely. This means a battery can make a partial buyback plan viable — if you are storing most of your excess rather than exporting it, the buyback rate matters less.

The economics break down like this: with a good 1:1 buyback plan alone, most Texas homeowners see bill reductions of 75% to 85%. Adding a battery to a good plan pushes reductions to 85% to 95%. A battery paired with even a mediocre buyback plan often outperforms a great buyback plan without a battery, because avoiding TDU charges on nighttime usage is worth more than marginal improvements in export credit rates.

The Bottom Line: Your Plan Matters as Much as Your Panels

Not being on the right buyback plan is the number one reason Texas solar homeowners feel disappointed by their savings. A well-sized solar system on a poor buyback plan can save you 40% to 50% on electricity. That same system on a competitive 1:1 plan saves 75% to 85%. The difference over a year can easily exceed $1,000.

Take the time to compare plans across multiple REPs, paying attention to the full picture — not just the headline buyback rate but also base charges, contract terms, credit rollover policies, and TDU passthrough structures. The Texas deregulated market gives you the power to choose, and choosing well is one of the highest-return decisions you can make as a solar homeowner.
