Your solar estimate
An estimate, not a quote: system size comes from your bill, production from NREL for your ZIP. No federal credit, rate increases, panel degradation or financing. How I calculate.
I went through utility interconnection records: 6,676 home solar systems were installed within 12.6 miles of central San Antonio in 2022–2024, by 30 companies with 30 or more systems each. The five most active: Pure Energy Ca (705), Freedom Solar Power Tx (602), Freedom Forever (590), Greenstar Powerllc (521), Sunrun (417). Today, quotes average $2.20/W in San Antonio (EnergySage, updated 2026-09-04) — about $15,400 for a 7 kW system before incentives.
I don't install solar or rank companies; these are counts from public records. Hank is our illustrated character, not a real homeowner or installer. If you request quotes, your request goes to a referral network of installers. How I calculate.

Incentives and rules for San Antonio homeowners
- Federal tax credit: the 30% Residential Clean Energy Credit is not available for property placed in service after December 31, 2025 (IRS).
- CPS Energy: Monthly bill = full-service rate less Net Excess Generation credit; NEG credit = NEG kWh x avoided energy cost (fuel + variable O&M + losses), applied to the next bill, not above the total electric bill, balance carries over. Seasonal NEG values come from a 2024 billing sample; current 2026 values requested from CPS 2026-09-14. Residential solar rebates are not currently offered (CPS FAQ).
- Property tax: Tax Code Section 11.27: exemption of the appraised value added by a solar energy device primarily for production and distribution of energy for on-site use; apply to the county appraisal district with Form 50-123 between January 1 and April 30.
- Selling power back: No statewide net metering rule; export compensation is set by each utility. CPS Energy is a municipal utility outside the competitive market.
