San Antonio’s utility is CPS Energy, a municipal utility outside Texas deregulation, so you do not pick a retail provider here. CPS credits the solar you export at its lower avoided-cost rate, not full retail. A typical 6 kW roof makes about 8,981 kWh a year. Verify CPS Energy’s current rate and rebate status.
If you own a home in San Antonio, your electric utility is CPS Energy, and that one fact changes how rooftop solar pays you back. Most of Texas is a deregulated market where you shop for a retail electric provider, but San Antonio is not. CPS Energy is a municipal utility that sets its own rates and its own solar rules. This page explains how CPS credits your exported solar, what a San Antonio roof is likely to produce, where the local rebate stands in 2026, and how permitting and interconnection work here.
San Antonio and CPS Energy at a glance
San Antonio sits outside Texas retail choice. CPS Energy owns the wires and the billing, so your solar value comes from CPS rules, not from a competitive plan you shop for. Here is the shape of it in 2026.
| Detail | What to know |
|---|---|
| Your utility | CPS Energy, a municipally owned utility, not a deregulated retail provider |
| Market type | Outside Texas retail choice, so there is no retail electric provider to shop |
| Solar export credit | Net excess generation credited at CPS Energy’s avoided-cost rate, below full retail |
| Typical production | About 8,981 kWh a year from a 6 kW system (ZIP 78205) |
| Residential rebate | The old CPS residential rooftop rebate is no longer funded; verify current status with CPS Energy |
| Permitting | A City of San Antonio Development Services permit plus a separate CPS interconnection agreement |
| Sources | DSIRE: CPS Energy net metering, EIA |
How CPS Energy credits your solar: avoided cost, not net metering
The single most important San Antonio detail is that CPS Energy does not offer full-retail, one-to-one net metering. You still buy grid power at your normal retail rate, but the surplus solar you send back is credited at CPS Energy’s avoided-cost rate, which is lower than retail (DSIRE, last updated February 2026). In plain terms, the power you use in your own home while the sun is up is worth the most, and the power you export is worth less. That is different from the deregulated parts of Texas, where any solar buyback depends on a retail provider’s plan, and different from a true net-metering state. Because CPS pays less for exports than for the power you offset directly, sizing your system to your own daytime usage matters more here than chasing a big export surplus. Confirm the current avoided-cost figure on your CPS Energy rate schedule before you model savings, since the rate moves over time. For the mechanics of how export credits work in general, see how net metering credits your solar exports.

What a San Antonio roof produces
South Texas sun is the good news. According to MySolarFY’s analysis (August 2026), a typical 6 kW rooftop system in San Antonio produces about 8,981 kWh a year, modeled from NREL’s PVWatts for ZIP 78205 (PVWatts calculator). That works out to roughly a 17% capacity factor, strong for a rooftop system, and it is why San Antonio is a solid solar market even without one-to-one net metering. Your actual output depends on roof pitch, orientation, and shade from those live oaks, so treat the figure as a starting estimate and run your own address. Statewide, Texas homes pay about 16.4 cents per kWh (EIA Electric Power Monthly, Table 5.6.A, May 2026); CPS Energy’s residential rates have historically run below that statewide average, so check your own CPS bill for the rate solar actually offsets for you. To see how the bill credit lowers your monthly cost, read how solar lowers your electricity bill.
The CPS Energy rebate question in 2026
Do not budget around a San Antonio residential solar rebate without confirming it is open. CPS Energy ran a well-known residential rooftop solar rebate for years, but that residential funding was exhausted and the residential rebate is no longer being paid out. DSIRE still lists a CPS rebate tied to net-metering enrollment as of February 2026, so the honest answer is that any current CPS incentive may be limited or aimed at commercial customers, and the residential picture changes with each budget cycle (DSIRE). The right move is to verify the live status and dollar amount directly with CPS Energy before you sign anything, and to treat your quote’s economics as sound without a rebate. A licensed installer who works in San Antonio every week will know the current program state.
Permits and interconnection in San Antonio
Going solar in San Antonio means two separate approvals: a city permit and a CPS Energy interconnection. You cannot energize the system until CPS completes its commissioning and sets the meter. The general path is:
- City permit. Your installer files a building and electrical permit with the City of San Antonio Development Services Department before work begins (San Antonio DSD, Information Bulletin 153).
- CPS interconnection application. A separate interconnection agreement goes to CPS Energy with a one-line diagram, a site plan, and equipment specifications.
- Install and city inspection. The system is installed by a licensed electrician and passes a Development Services inspection.
- Commissioning and meter. After the permit is released, CPS Energy schedules a commissioning test and sets a bidirectional meter that measures what you export.
- Permission to operate. Only after CPS signs off can the system run on the grid.
City permit fees for a residential solar system in San Antonio generally fall in the low hundreds of dollars, and a licensed installer normally manages the whole permit-and-interconnection process for you. For the questions to ask before you hire, see the right questions to ask a solar installer.
Texas is deregulated, but San Antonio is not
This is the part that trips up San Antonio homeowners reading generic Texas solar advice. Across most of Texas, the electricity market is deregulated: you choose a retail electric provider for your energy while a regulated wires company delivers it, and any solar buyback depends on whether your provider offers a solar plan, at a rate that is not fixed statewide. San Antonio and Austin are the big exceptions. Both are served by municipal utilities, CPS Energy here and Austin Energy in Austin, that sit outside retail choice and run their own solar programs. So advice about picking a solar buyback plan from a competitive provider simply does not apply in San Antonio; your terms come from CPS Energy. For the statewide picture, see our Texas solar incentives guide, and to weigh the numbers, see the Texas solar cost breakdown.
What changed federally, and what it means in San Antonio
The federal homeowner credit is gone, but San Antonio’s sun and CPS bill offset are not. 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 San Antonio homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS OBBB FAQ; SEIA). The value of San Antonio solar now rests on the power you offset at CPS retail rates plus strong South Texas production, not on that expired credit. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner, and it runs for projects placed in service through 2027, with a begin-construction safe harbor by July 4, 2026 (IRS Clean Electricity Investment Credit). For a leased system in San Antonio you do not file for a federal credit yourself; the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025.
How you pay changes your San Antonio solar value
Ownership decides who keeps the value. On a lease or PPA the company that owns the panels typically keeps the bill credits, while your benefit is a lower or fixed power price with no up-front cost. Here is how the paths compare under CPS Energy.
| How you pay | Up-front cost | Who owns the system | Who keeps the CPS bill credits |
|---|---|---|---|
| Cash | Full system price | You | You |
| Solar loan | Little or none, financed over time | You | You |
| Lease or PPA | $0-up-front where you qualify | A third-party company | Usually the company that owns the panels |
If you own the system through cash or a loan, you keep the CPS Energy bill credits and the avoided-cost export credit yourself. Neither path gives a 2026 San Antonio homeowner the federal residential credit, since that credit ended after December 31, 2025. For a deeper payback comparison, see the financial case for whether solar panels are worth it.
How to choose a solar installer in San Antonio
San Antonio has a deep market of solar installers, so screen any company against objective criteria rather than a “best” list:
- NABCEP certification, the industry’s professional standard for PV installers.
- A licensed electrician and any required City of San Antonio permits.
- Real experience with CPS Energy interconnection, so the commissioning and meter set go smoothly.
- A clear workmanship and equipment warranty in writing.
- A written production estimate and a transparent quote that is honest about CPS Energy’s avoided-cost export credit and the current rebate status. For a checklist, see the right questions to ask a solar installer, and to weigh payback, see the financial case for whether solar panels are worth it.

Frequently asked questions
Does CPS Energy offer net metering in San Antonio?
Not full-retail, one-to-one net metering. CPS Energy credits the surplus solar you export at its avoided-cost rate, which is lower than the retail rate you pay for grid power (DSIRE, updated February 2026). The practical effect is that the solar you use directly in your home is worth more than what you export, so sizing a system to your own daytime usage gives the best result. Confirm the current avoided-cost figure on your CPS Energy rate schedule, since it moves over time.
Is there still a CPS Energy solar rebate for homeowners?
The residential rooftop rebate that CPS Energy ran for years is no longer being paid out after its funding was used up, so you should not assume one is available. DSIRE still lists a CPS rebate tied to net-metering enrollment as of February 2026, which means any current incentive may be limited or aimed at commercial customers. Verify the live residential status and dollar amount directly with CPS Energy before you count on it, and make sure your quote works without a rebate.
How much solar power will a San Antonio home produce?
According to MySolarFY’s analysis (August 2026), a typical 6 kW rooftop system in San Antonio produces about 8,981 kWh a year, based on NREL PVWatts modeling for ZIP 78205. That is roughly a 17% capacity factor, strong for a rooftop system thanks to South Texas sun. Your real output depends on roof pitch, orientation, and shading, so run your own address before you decide.
What happened to the federal solar tax credit in San Antonio?
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 San Antonio 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 business that owns the system claims it, not the homeowner. The value of solar here now rests on CPS bill offset and strong production.
Do I pick a retail electric provider for solar in San Antonio?
No. Unlike most of Texas, San Antonio is outside the deregulated retail market. Your utility is CPS Energy, a municipal utility, so there is no retail electric provider to shop and no competitive solar buyback plan to choose. Your solar terms, including the avoided-cost export credit, come from CPS Energy directly.
What permits do I need for solar in San Antonio?
Two approvals: a building and electrical permit from the City of San Antonio Development Services Department, and a separate interconnection agreement with CPS Energy (San Antonio DSD IB153). After the install passes city inspection and the permit is released, CPS Energy runs a commissioning test and sets a bidirectional meter, and only then can the system operate. A licensed installer usually handles the whole process for you.
