San Antonio's price band
San Antonio is cheaper than 92% of the 195 US metros we price for solar panel work.
Expect $16,450–$25,850 for 8 kW of panels, $19,950–$31,400 for 10 kW, and $10,800–$17,350 more for a Tesla Powerwall 3. Every price here is before incentives, and the federal homeowner credit is gone for 2026 installs.
CPS Energy, San Antonio's city-owned utility, sets its own solar terms and rebates, so ask what is open now. EnergySage's November 2026 San Antonio quotes average about 15% below its US figure, and hail is a real risk.
Every price here is before incentives, and there is no federal one left for systems you own: the 30% credit ended for expenditures after December 31, 2025, and the IRS treats the expense as made when the install is complete. Texas has no state solar tax credit, but the added home value is exempt from property tax if you file Form 50-123.

Prices cover the San Antonio metro and assume a pitched shingle roof in good shape. Older roofs in East Side & Southeast more often need repair first.
Solar panel prices across San Antonio
Same system, four price bands. The spread comes from roof type, access and shade: tighter and older in Downtown, Southtown & the Pearl, easier in Stone Oak, Alamo Heights & the Northside.
Downtown, Southtown & the Pearl
- 8 kW installed
- $17,450–$27,900 installed
- Typical job
- $13,750–$33,900 / 6–10 kW system
Flat roofs, older buildings and little street parking. Arrays here often need tilt racking or weighted mounts, fire-code walkways cut the panel count, and permit reviews take longer.
East Side & Southeast
- 8 kW installed
- $16,950–$26,900 installed
- Typical job
- $13,350–$32,650 / 6–10 kW system
Older homes with character roofs and 100-amp panels. Ask early whether the roof has 10 years of life left and whether the job needs a panel upgrade.
West Side & South Side
- 8 kW installed
- $16,450–$25,850 installed
- Typical job
- $12,950–$31,400 / 6–10 kW system
Typical single-family roofs and typical prices. Most installs here take one to three days on the roof.
Stone Oak, Alamo Heights & the Northside
- 8 kW installed
- $16,100–$25,850 installed
- Typical job
- $12,700–$31,400 / 6–10 kW system
Big roofs and big bills. Larger systems cost less per kW, and this is where most 10–12 kW jobs in the metro are.
Real solar jobs in San Antonio
Here's what common solar panel jobs cost in San Antonio in 2026, installed, before incentives.
Smaller home: 6 kW, standard panels
About 25 kWh on an average day at Texas's sun levels. Smaller systems cost more per kW, about $2,650 here against $2,500 for 8 kW.
Typical home: 8 kW, standard panels
About 33 kWh a day and 12,200 kWh a year. $20,050 is the typical San Antonio price for a pitched shingle roof in good shape.
Solar plus a Powerwall 3
An 8 kW system with a 13.5 kWh battery for outages and evening use. Doing both in one job shares the crew, the permit and the utility paperwork.
Big home or EV owner: 10 kW, premium panels
Premium panels make more power per square foot, which helps on small or shaded roofs. Standard panels at 10 kW are $19,950–$31,400.
Re-roof with solar already on it
Taking about 20 panels off and putting them back after the roofers leave, on top of the roof itself. If your roof has less than 10 years left, replace it before solar goes on.
How much do solar panels cost in San Antonio?
$16,450–$25,850 installed, with $20,050 the typical San Antonio price for 8 kW. Only about a third of that is hardware (panels, inverter, racking). The rest is sales, design, permits, labor and profit, and that is the part that changes from one San Antonio installer to the next.
There is no federal credit to take off these numbers any more. What still cuts the bill in San Antonio is a second or third quote, the right system size for your actual use, and any state or utility program. Figures re-verified against 42 sources in November 2026.
Solar prices in San Antonio (2026): the lines on a quote
An 8 kW system is $16,450–$25,850 installed, a battery adds $8,450–$17,350, and a panel upgrade adds $1,350–$4,100 if your panel is full.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| 8 kW system, standard panels | $16,450 | $20,050 | $25,850 |
| 8 kW system, premium panels | $18,100 | $23,050 | $32,350 |
| Tesla Powerwall 3, added at install | $10,800 | $13,800 | $17,350 |
| Main panel upgrade (to 200 amps) | $1,350 | $2,300 | $4,100 |
| Tile roof, extra | $900 | $1,550 | $2,250 |
| Ground mount, extra | $3,600 | $5,800 | $8,950 |
| Critter guard | $630 | $1,050 | $1,500 |
| String inverter replacement (later) | $1,400 | $2,150 | $3,300 |
Standard vs premium panels in San Antonio: the gap on 8 kW is about $3,000. Premium panels pay off on small or shaded roofs where you need more power per square foot; on a big sunny roof, standard panels are the better buy.
What moves a solar quote in San Antonio:
- System size — bigger systems cost less per kW: about $2,650 at 6 kW against $2,450 at 10 kW.
- Panel and inverter brand — premium panels run 10–25% more; microinverters cost more than one string inverter but last longer.
- The roof — tile adds $900–$2,250, a ground mount $3,600–$8,950, and a worn roof should be replaced first.
- The electrical panel — a full or 100-amp panel can add $1,350–$4,100 for an upgrade.
- Who sells it — sales and marketing are about 15% of a typical price; local installers often quote less than national brands.
Ask every San Antonio installer for the same five things: system size in kW, panel and inverter models, the price per kW, the warranty terms, and what roof, panel and permit work is included. Compare those lines, not the total. Get a quote for your solar install →
Solar Panel Cost in San Antonio by System Size
A 6 kW system is $12,950–$20,300, 8 kW is $16,450–$25,850, and 10 kW is $19,950–$31,400, installed with standard panels, before any state or utility incentive.
Worked example: a San Antonio home using about 1,000 kWh a month gets an 8 kW system at $20,050. If the panel is 100 amps, add an upgrade at $2,300 for $22,350. Add a Powerwall 3 in the same job and the total is about $35,450.
A larger home with central AC or an EV may need 10–12 kW: $24,350 for 10 kW, or $30,000 for 12–13 kW at typical prices. Premium panels on 10 kW run $21,950–$39,300.
San Antonio Solar Panel Costs by System Size
| System size | Cost | Best for |
|---|---|---|
| 4 kW system — about 17 kWh a day | $9,600–$15,100 installed | Small home or condo; low bills or a small roof |
| 6 kW system — about 25 kWh a day | $12,950–$20,300 installed | Smaller home or modest power use |
| 8 kW system — about 33 kWh a day | $16,450–$25,850 installed | Typical home; about 1,000 kWh a month of use |
| 10 kW system — about 42 kWh a day | $19,950–$31,400 installed | Larger home, central AC or one EV |
| 12 kW system — about 50 kWh a day | $23,750–$37,400 installed | Big home, pool or electric heat |
| 15 kW system — about 63 kWh a day | $28,700–$45,100 installed | Very large all-electric home or two EVs |
| 8 kW solar + 13.5 kWh battery | $26,700–$42,350 installed | Backup in outages and evening use where exports earn little |
| 13.5 kWh battery only (no solar) | $10,800–$17,350 installed | Backup without panels; shaded roofs |
Hardware vs everything else: where a San Antonio solar quote goes
Panels, inverter, racking and wiring are only about 41% of a typical US solar price. On a $20,050 San Antonio job that is roughly $8,200. Sales and marketing take about 15%, design, paperwork and overhead about 20%, installer profit about 16%, and the install labor itself only about 6%.
That is why the payback math matters more than the panel brand. An 8 kW system here makes about 12,200 kWh a year. At Texas's 2024 average of 9.8 cents a kWh across all customers (EIA; home rates usually run higher), that power is worth about $1,200 a year, a simple payback near 17 years. Texas has no statewide net metering rule, so what your exports earn depends on your utility or retail plan.
What's included in a San Antonio solar quote (and what costs extra)
A standard quote covers the panels, inverter, racking, wiring, the install crew, permits, inspection and the utility hookup paperwork. The headline price often leaves out:
- Roof work — repairs, or $900–$2,250 extra for a tile roof
- Panel upgrade — $1,350–$4,100 if your electrical panel is full or 100 amps
- Critter guard — $630–$1,500 to keep birds and squirrels out from under the panels
- A battery — $8,450–$17,350 for 10–13.5 kWh of storage, if you want backup

What's local
CPS Energy, San Antonio's city-owned utility, sets its own solar terms and rebates, so ask what is open now. EnergySage's November 2026 San Antonio quotes average about 15% below its US figure, and hail is a real risk.
System size
An 8 kW system is $16,450–$25,850. A 6 kW system is $12,950–$20,300 and 10 kW $19,950–$31,400; the price per kW drops as the system grows.
Panels and inverters
Premium panels add 10–25% ($18,100–$32,350 for 8 kW). Microinverters cost more upfront than one string inverter but usually carry 20–25 year warranties; a string inverter often needs replacing once ($1,400–$3,300).
Your roof
Clay or concrete tile adds $900–$2,250, a ground mount $3,600–$8,950. If the roof has less than about 10 years left, re-roof first: removing and reinstalling panels later costs $3,150–$7,150.
Your electrical panel
A full or 100-amp panel is a common surprise. Upgrading to 200 amps adds $1,350–$4,100 in San Antonio, and it is cheapest done with the solar job.
Adding a battery
A 10–13 kWh battery adds $8,450–$15,950, a Tesla Powerwall 3 $10,800–$17,350. Batteries make the most sense where outages are common or exports earn little.
Permits and the utility in San Antonio
Permits and inspections are about 3% of a typical price, and the utility must approve the hookup before you can switch on. Ask who files the paperwork; a good installer does all of it.
- Get three quotes.Same panels, different sales costs. San Antonio quotes for 8 kW run $16,450–$25,850; a second and third bid is the fastest way to find the padding.
- Compare the price per kW.Divide each quote by its size in kW. About $2,050–$2,500 per kW is a good San Antonio price for standard panels; much above $3,200 needs a reason.
- Size it to your bills, not your roof.Use 12 months of bills. A system that makes more than you use only pays off if your utility credits exports well.
- Fix the roof first.Re-roofing under existing panels means paying $3,150–$7,150 to take them off and put them back.
- Bundle the panel and battery work.A panel upgrade ($1,350–$4,100) or a battery done in the same job shares the permit, the inspection and the utility visit.
- Check state and utility help.Texas has no state solar tax credit, but the added home value is exempt from property tax if you file Form 50-123. Ask your utility about rebates and how it credits exports before you sign.
Before you pay a deposit to a San Antonio solar installer, get these in writing:
- System size in kW and the expected output in kWh a year
- Panel and inverter brand and model
- Price per kW and the total before incentives
- Roof work, tile or ground-mount extras, priced as their own lines
- Any panel upgrade, priced as its own line
- Permit, inspection and utility interconnection, and who files them
- Warranties: panels, inverter, workmanship and roof leaks
- Payment schedule, and what happens if the utility hookup is delayed

Not for systems you buy. The 30% Residential Clean Energy Credit ended for expenditures made after December 31, 2025, and the IRS treats the expense as made when installation is complete. Lease and PPA companies may still claim a business credit and pass some of it on in their price.
How much does solar with a battery cost in San Antonio?

Roughly 17 years for a typical 8 kW system at Texas's 2024 average power price from EIA (9.8 cents a kWh across all customers), with every kWh worth the full price. Texas has no statewide net metering rule, so what your exports earn depends on your utility or retail plan.

What does solar panel cleaning and upkeep cost in San Antonio?
Cleaning is $130–$450 a visit and a health check $130–$310. Many roofs never need cleaning; rain does most of it. Budget $1,400–$3,300 for one string inverter replacement over the life of the system.
How much does it cost to remove solar panels for a new roof in San Antonio?
$3,150–$7,150 to take about 20 panels off and put them back, on top of the roof itself.
What permits does solar need in San Antonio?
A building or electrical permit, an inspection, and the utility's approval to connect. Your installer should file all of it; permits and inspections are about 3% of a typical price.
