San Antonio is Texas's best solar market thanks to CPS Energy's municipal programs. With 220 sunny days (NOAA data), 1:1 net metering, and rebates of $0.40-0.60/watt, expect 6-9 year paybacks.

From my experience:San Antonio is where I tell people to look when they think Texas solar is complicated. CPS Energy makes it simple—real rebates, 1:1 net metering, no shopping around for retail electricity providers. The rebate funds do run out, though. I've seen people wait for "the right time" and miss the rebate window by a month. If you're serious, check the current rebate status and don't sit on it. San Antonio's solar market is one of the most straightforward in Texas.
