Cost to Solar Panel Installation in San Antonio, TX (2026)
If you’re budgeting a solar panel installation in San Antonio, most projects run $14,062-$28,123, 6% below the $20,000 national average. What moves that number most is usually one thing: System Size (kW). On its own it can swing the cost by $7,500 - $40,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Claim the 30% federal Investment Tax Credit (ITC) - on a $20,000 system, that is $6,000 back on your taxes
In the Southeast (where San Antonio sits): Good sun exposure and lower labor costs. State incentives vary widely - Florida has no state tax credit.
