Solar buyback plans in Texas: how the bill credits actually work

If you have solar panels, a solar buyback plan lets the extra power you generate but do not use earn credits on your bill instead of going to waste. Below is a plain-English walk through how buyback works in Texas, roughly what the credits are worth, when a buyback plan is worth it, and the handful of things to compare before you sign up. For a full overview and to compare plans at your address, see our Texas solar buyback hub.

What is a solar buyback plan?

A solar buyback plan is a retail electricity plan built for homes that already have working solar panels. When your panels make more electricity than your home is using at that moment, the surplus flows back out through your meter and onto the local grid. On a buyback plan, that exported power shows up as a credit on your bill, lowering what you owe for the grid power you still pull at night and on cloudy days.

It is worth being clear on what a buyback plan is and is not. Energy Direct sells the electricity plan, not the panels. Your panels and inverter are installed by a separate solar installer of your choice. And no matter which plan you pick, your local Transmission and Distribution Utility (TDU) still owns the poles, wires, and meters and restores outages. In Texas that TDU is typically Oncor, CenterPoint Energy, AEP Texas, or TNMP, depending on where you live. Your retail plan only sets your price, term, credit terms, and billing.

A simple example

• Your panels generate 800 kWh this month
• Your home uses 600 kWh of that as it is produced
• The other 200 kWh flows back to the grid as surplus
• Your buyback plan credits you for those 200 exported kWh, at the rate set in the plan

How much does solar buyback pay?

This is where the details matter, and where availability and terms vary by plan, so the only number that truly counts is the one on the plan's Electricity Facts Label (EFL). Broadly, Texas buyback plans fall into two styles, and they credit you very differently:

• Net-metering-style plans net your exports against your usage so that, up to your monthly consumption, exported kWh can offset purchased kWh at or near the same value. A true 1:1 credit on every kWh is not guaranteed, and many plans cap the credit at your monthly usage, so confirm the terms on the EFL.
• Fixed-rate buyback plans pay a set price for each exported kWh, often lower than the retail rate you pay to buy power. The gap reflects delivery and market value, so you typically will not earn the full retail rate on the surplus you sell back.

To make this concrete: if you buy power at, say, 12¢ per kWh and a fixed-rate buyback plan credits exports at 6¢ per kWh, then 200 surplus kWh in a month is worth about 200 × 0.06 = $12 in credits, or roughly $144 a year at that pace. A net-metering-style plan that credits closer to the retail rate would be worth more on the same export volume. Those figures are illustrative, not a quote. Your real credit depends on your plan, your TDU, and how much you actually export.

Is a solar buyback plan worth it?

When it tends to make sense

• You have roof space with good sun exposure and panels that already export surplus power.
• Your home regularly sends meaningful excess back to the grid rather than consuming all it makes.
• You plan to stay in the home long enough to benefit from the credits.
• Your address and TDU support a buyback or net-metering-style plan.

When it may matter less

• Your usage is high enough that you consume nearly all your solar output, leaving little to export.
• Your roof is heavily shaded or poorly oriented, so production is low.
• A plan's monthly fees or low buyback rate cancel out most of the credit value.

Tips for getting the most from a buyback plan

• Compare how exports are credited, not just the headline rate. A slightly higher rate you pay can still net out better if the buyback credit is stronger.
• Consider pairing solar with battery storage. Storing surplus for evening use can beat exporting it at a reduced buyback rate, depending on your plan.
• Shift heavy loads into daylight hours. Running the dishwasher, laundry, or EV charging while the sun is up uses your own solar before it is exported.
• Watch your production. Most solar systems include an app that shows real-time generation, which helps you time usage and confirm your panels are performing.

Bottom line

For a Texas home that already has solar, a buyback plan is a sensible way to put the surplus power your panels make toward your bill instead of letting it go to waste. The credits can be modest, especially on fixed-rate buyback plans, but they add up over a year. The right plan for you comes down to how much you export, how that surplus is credited, and the fees and term attached, all of which live on the Electricity Facts Label. Compare those side by side, start from your own address rather than a statewide average, and you will know whether the numbers work for your home.
