Texas Home Solar in 2026: Power to Choose, Net Metering, and Real Savings

Texas has no state income tax — and no uniform net metering rule. Here's how deregulated electricity markets affect solar payback and what to check before you sign.

Texas produces more solar than almost any US state — sunshine is not the problem. Retail choice is. In deregulated markets (ERCOT), your REP contract and export terms matter as much as panel quality.

Key takeaway: In Texas, read the electricity plan and interconnection agreement together. Two identical systems can have very different payback depending on your REP.

Deregulated vs regulated areas

Area type	Examples	Solar consideration
Deregulated (ERCOT)	Houston, Dallas, most metros	Shop REP + solar export adder
Regulated munis/co-ops	Austin Energy, CPS (San Antonio)	Utility-specific solar rules
Outside ERCOT	El Paso, parts of Panhandle	Different grid, different rules

Net metering is not statewide

Unlike California or New York, Texas does not mandate full retail net metering statewide. Common setups:

Buyback / solar export rider — fixed ¢/kWh for exports
Real-time wholesale value — can be volatile
No export credit — rare but possible on some plans

Ask installers: "Which REP plans have you successfully paired with this system size?"

Typical Texas system economics (2026)

System size	Installed cost (USD)	Strong fit when…
8 kW	$18,000–$26,000	Bill $150–$250/mo, high summer AC
12 kW	$24,000–$34,000	Large home, pool, EV
+ battery	+$10,000–$18,000	Backup during outages

Payback often lands 7–12 years without strong export credits — faster if you have high daytime usage and a favorable buyback plan.

Storms, hail, and insurance

Texas homeowners should confirm:

Hail-rated panels and installer workmanship warranty
Homeowner insurance rider for solar
Dealer/Manufacturer bankability (25-year product warranty)

Compare quotes the Texas way

Same annual kWh production estimate across quotes
Same REP export assumption (or "worst case" sensitivity)
Roof warranty and penetration details in writing
Local permit and HOA approval timeline
