Quick Answer
CPS Energy in San Antonio is one of Texas best solar markets. Full retail net metering plus cash rebates ($0.40-0.60/watt, meaning $3,200-4,800 off an 8 kW system) create 6-9 year paybacks. Unlike deregulated Houston/Dallas, CPS offers straightforward municipal utility economics. Key tip: apply for rebates early—funds are limited and run out each program year.
CPS Energy Overview
CPS Energy is the nation's largest municipally owned energy company, serving San Antonio and surrounding areas. Unlike deregulated Texas, CPS offers straightforward solar programs with rebates and net metering.
From my experience:San Antonio is the sweet spot in Texas for solar. While Houston and Dallas homeowners are fighting with REPs over buyback rates, CPS customers get straightforward net metering AND cash rebates. That $0.40-0.60/watt rebate can mean $3,000-5,000 off your system—but here's the catch: the fund runs out. Every year I see people miss the rebate window because they waited too long. If you're in San Antonio thinking about solar, apply for the rebate early in the fiscal year. The municipal utility model here actually works in your favor for once.
