How I calculate this
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 still in business: 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.
Counts from public records, not rankings; quote requests go to a referral network. How I calculate.
