Red flags when choosing an installer

- No itemized quote or vague equipment brands
- No mention of utility interconnection timeline
- Door-to-door sales with no local reviews
Texas licensing & incentives context
Texas has no statewide solar rebate but the 30% federal ITC applies. Some municipal utilities ( Austin Energy, CPS Energy) offer local rebates.
Texas is the fastest-growing solar market in the US, with no state income tax and strong sun in Houston, Dallas, San Antonio, and Austin. Most Texas utilities use buyback programs rather than full net metering — understand your REP's solar buyback rate.
