As of August 2026, Laredo homes sit in AEP Texas territory in the deregulated ERCOT market, so AEP Texas delivers your power while a Retail Electric Provider sets any solar buyback. Laredo’s intense South Texas sun drives high production, and the City of Laredo requires a $200 solar permit before work starts.
- AEP Texas is a wires-only utility, not your energy seller. It is the transmission and distribution utility (TDU) that delivers power across South and West Texas, including Laredo and the rest of Webb County (AEP Texas, service territory).
- Your buyback comes from your Retail Electric Provider, not AEP Texas. Texas has no statewide net metering, so in the ERCOT market export value depends entirely on the solar buyback plan you pick from a competitive provider.
- Laredo has one of the strongest solar resources in Texas. NREL models about 5.8 peak sun-hours a day for ZIP 78040, higher than Dallas or Houston, so a right-sized system produces a lot of power here.
- Texas residential power averages about 16.44 cents per kWh (EIA retail sales, May 2026), so offsetting your own usage is where most of the value sits.
- The City of Laredo requires a solar permit. Ordinance 2024-O-247 sets a $200 solar panel permit fee (plus a $20 residential technology fee), and the permit must be obtained before work starts (City of Laredo Building Development Services).
- The 30% federal homeowner credit (Section 25D) ended for expenditures after December 31, 2025 (IRS).
If your power pole in Laredo belongs to AEP Texas, one fact shapes how rooftop solar pays you back: AEP Texas delivers your electricity, but it does not sell it to you and it does not set what your solar exports are worth. That is how the deregulated ERCOT market works. AEP Texas is the transmission and distribution utility, or TDU, that owns the poles and wires and handles interconnection, while a separate Retail Electric Provider, the REP you signed up with, bills you and decides whether it offers a solar buyback plan. What makes Laredo different from a lot of Texas is the sun: this border city on the Rio Grande gets some of the most intense sunshine in the state, which lifts how much a rooftop array produces. This page explains the AEP Texas split, walks through Laredo permitting and interconnection, and shows how to size and shop a system so the numbers work in Webb County. Because AEP Texas is the wires company across South Texas, its interconnection steps and fees look the same here as in the rest of its territory; for that region-wide detail, see our AEP Texas solar guide.
Laredo solar at a glance
AEP Texas handles the delivery side of your electric service in Laredo. The retail side, including any credit for exported solar, sits with your competitive provider, which is the piece that trips up most first-time Texas solar shoppers.
| Detail | What to know in Laredo |
|---|---|
| Your utility (TDU) | AEP Texas, the transmission and distribution utility for Laredo and Webb County. It delivers power and runs interconnection. It is not a retail seller of electricity. |
| Market | Deregulated ERCOT. You choose a Retail Electric Provider for your energy plan, and that provider decides any solar buyback. |
| Solar resource | About 5.8 peak sun-hours a day for ZIP 78040 (NREL), among the highest in Texas thanks to the dry South Texas climate |
| Who pays your buyback | Your Retail Electric Provider, through its own solar buyback plan. AEP Texas does not set or pay it. |
| Net metering | No statewide mandate in deregulated Texas. Credit terms vary plan to plan. |
| Local permit | The City of Laredo requires a solar panel permit ($200 fee plus a $20 residential technology fee) before work starts, under Ordinance 2024-O-247 |

According to MySolarFY’s analysis (August 2026), a typical 8 kW rooftop system in Laredo is modeled to produce about 12,700 kWh a year (NREL PVWatts, ZIP 78040), worth roughly $2,085 at Texas’s average residential rate of 16.44 cents per kWh. That is higher than the same-size system in Dallas, which reflects Laredo’s stronger sun, though in AEP Texas’s deregulated territory the real dollar value of that solar depends on the buyback plan your Retail Electric Provider offers, not on AEP Texas. Estimate your own roof with NREL’s free PVWatts calculator before you shop plans.
The Laredo difference: delivery is AEP Texas, the buyback is your REP
In deregulated Texas, two different companies touch your solar, and only one of them pays you for exports. AEP Texas owns the wires and charges a delivery fee that appears on your bill no matter which provider you use. Your Retail Electric Provider is the company you signed up with for a rate plan, and it is the one that decides whether it buys back the surplus your panels send to the grid. Because Texas has no statewide net metering to fall back on, the single most important solar decision in Laredo is not the utility, it is which solar buyback plan you choose. Plans differ on the credit rate for exports, whether credits are 1:1 or lower, whether unused credits roll over, and the underlying energy rate you pay for the power you still import at night. Comparing these plans is the work. For how export credits function in general, see how net metering credits your solar exports. For the statewide picture, see our Texas solar guide and our Texas solar cost breakdown.

Permitting and interconnection in Laredo
Solar in Laredo passes through two separate approvals, and it helps to know which body does what. The City of Laredo handles the local building and electrical permit, and AEP Texas, as the TDU, handles the grid interconnection and the meter work that lets your system safely export power. The general path is:
- Pick a licensed installer. Your installer designs the system and manages the paperwork on both the city and utility sides.
- City of Laredo solar permit. A solar panel permit must be obtained before work starts, with a $200 permit fee plus a $20 residential technology fee under Ordinance 2024-O-247 (City of Laredo Building Development Services).
- AEP Texas interconnection. Your installer submits the distributed generation interconnection application to AEP Texas, the TDU, which reviews the design for a safe, reliable connection to its wires.
- Install and inspect. The system is installed and passes the required City of Laredo electrical and building inspection.
- Permission to operate. After city inspection and the interconnection review, AEP Texas completes the meter work that allows your system to export to the grid. You cannot energize the system until that approval is in place.
Timelines vary by project, so build in a buffer, and a licensed installer normally handles both the city permit and the AEP Texas application for you. Confirm the current AEP Texas interconnection steps and any updated Laredo fees with your installer before you sign. For the questions to ask first, see the right questions to ask a solar installer.
Net metering and the buyback in AEP Texas territory
There is no statewide net metering in Texas, so your buyback is a shopping decision. In a regulated state, one utility credits your exports at a set rate. In deregulated ERCOT, AEP Texas delivers the power and your Retail Electric Provider decides what, if anything, it pays for exports through a solar buyback plan. That is both a catch and an opportunity. The catch is that a cheap-looking rate plan may offer little or no export credit, so oversized production can be wasted, which matters more here because Laredo’s strong sun makes it easy to over-produce in summer. The opportunity is that you can shop for a provider whose buyback plan fits how your household uses power. A few things to compare between plans:
| Compare between buyback plans | Why it matters in Laredo |
|---|---|
| Export credit rate | Laredo’s high midday production means lots of exports, so whether they are credited near retail or lower drives most of your value |
| Rollover of credits | Some plans roll unused credit forward; others zero it out each cycle, which hurts when summer over-produces |
| Import (energy) rate | Heavy summer air-conditioning means you still buy a lot of evening power, so the plan’s base energy rate matters as much as its buyback |
| Term and fees | Contract length, monthly base charges, and early-termination fees change the real cost |
Because Laredo summers push heavy cooling loads and long, sunny days, a battery can be worth a closer look here than in milder parts of Texas: it lets you store cheap midday solar and lean on it through the evening peak instead of exporting at a low credit rate. Whether it pays off depends on your provider’s plan and your usage, so price it both ways.

Frequently asked questions about solar in Laredo
Who is my utility for solar in Laredo?
AEP Texas is the transmission and distribution utility (TDU) for Laredo and Webb County. It owns the poles, wires, and meters and delivers your electricity, and it runs the interconnection that connects rooftop solar to the grid. AEP Texas is not a retail seller of power, so it does not set your rate and it does not pay your solar buyback. In Laredo’s deregulated ERCOT market, you pick a Retail Electric Provider for your energy plan, and that provider decides any buyback for exported solar. (Source: AEP Texas service territory)
Does AEP Texas pay me for my excess solar?
No. AEP Texas delivers power and runs interconnection, but it does not buy your surplus solar. In deregulated Texas your buyback comes from your Retail Electric Provider through its solar buyback plan. Because Texas has no statewide net metering, what your exports are worth depends entirely on the plan you choose. Compare providers on their export credit rate, whether credits roll over, and the base energy rate you pay for power you import at night. Sizing a system close to your own annual usage usually beats oversizing to chase export credits.
Do I need a permit to install solar in Laredo?
Yes. The City of Laredo requires a solar panel permit for residential rooftop solar, and it must be obtained before work starts. Under Ordinance 2024-O-247 the solar panel permit fee is $200, and a $20 technology fee applies to residential permits. The permit is processed through the City of Laredo Building Development Services. Your licensed installer normally pulls this permit and handles the AEP Texas interconnection application as part of the job. (Source: City of Laredo Building Development Services)
How much solar power does a Laredo home produce?
Laredo has one of the strongest solar resources in Texas, about 5.8 peak sun-hours a day for ZIP 78040 according to NREL. In MySolarFY’s August 2026 analysis, a typical 8 kW rooftop system is modeled to produce about 12,700 kWh a year (NREL PVWatts, ZIP 78040), which is more than the same-size system in Dallas. At Texas’s average residential rate of about 16.44 cents per kWh that output is worth roughly $2,085 a year, though the dollar value of exports depends on your provider’s buyback plan. Model your own roof with NREL PVWatts before you shop.
What happened to the federal solar tax credit in 2026?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Laredo homeowner who buys solar in 2026 with cash or a loan cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the company that owns the system claims it, not the homeowner. Texas’s strong solar resource and your provider’s buyback plan were not affected. MySolarFY does not provide tax advice; confirm your situation with a tax professional.

Should I add a battery to my Laredo solar system?
It is worth pricing. Laredo’s long, sunny days and heavy summer cooling load mean you often produce a lot of solar at midday and still buy power in the evening. A battery lets you store cheap midday solar and use it through the evening peak instead of exporting at a low buyback rate, and it adds backup during outages. Whether it pays off depends on your Retail Electric Provider’s plan and your usage pattern, so ask your installer to price the system both with and without storage before you decide.
