Texas Solar Overview
Texas is a fascinating solar market. After Winter Storm Uri, I saw interest in solar plus battery explode here. The deregulated market makes things tricky—you really need to shop for a solar buyback plan carefully. But when you find the right retail provider and pair it with that incredible Texas sunshine, the economics can work beautifully. Just do not assume net metering exists here—it is a whole different game.
Texas receives excellent solar resources—ranking among the top states for annual sunshine. The state is also the nation's largest electricity consumer, making solar a practical choice for many homeowners looking to reduce bills.
Payback period: 8-12 years
Annual sunshine: 200-300 sunny days — NREL PVWatts
Market type: Deregulated (most areas)
Why Texas Is Good for Solar
- Abundant sun: High solar production potential
- High electricity use: Larger savings opportunity
- Growing market: Competitive installer pricing
- Property tax exemption: Solar doesn't increase taxes
- No state income tax: No state credit, but no state tax either
Challenges in Texas
- No statewide net metering: Policies vary by utility/provider
- Deregulated market complexity: Many retail electricity providers
- Grid reliability concerns: Winter Storm Uri showed vulnerabilities
- HOA rules: Can sometimes complicate installations

Texas Solar Incentives
Federal Tax Credit (2026)
The federal solar Investment Tax Credit changed significantly in 2026:
- Purchased systems: The 30% residential credit (Section 25D) ended December 31, 2025
- PPA/Lease: Section 48E still provides 30% through 2027—passed to you as lower payments
- Already installed: Systems installed before 2026 still qualify
State Incentives
- State tax credit: None (Texas has no state income tax)
- Property tax exemption: 100% of added home value exempt
- Sales tax exemption: Solar equipment is taxable in Texas
Utility and Local Incentives
Some Texas utilities and cities offer additional incentives:
- Austin Energy: Has offered rebates (check current availability)
- CPS Energy (San Antonio): Rebate programs available
- Some co-ops: May offer incentives to members
Note: Local incentives change frequently. Always verify current programs with your utility.
Net Metering & Buyback
Texas doesn't have a statewide net metering requirement. What you receive for excess solar energy depends entirely on your utility or retail electricity provider.
ERCOT Deregulated Areas
Most of Texas (about 85% of customers) is in the deregulated ERCOT market. Here's how it works:
- Retail choice: You choose your electricity provider
- Buyback varies: Each provider has different solar buyback rates
- Some offer 1:1: A few providers offer full retail credit
- Most offer less: Many pay wholesale or avoided cost rates
Regulated Utility Areas
Some areas (Austin, San Antonio, co-ops, munis) have regulated utilities:
- Austin Energy: Value of Solar rate (varies)
- CPS Energy: Net metering available
- Co-ops: Policies vary widely
Finding Solar-Friendly Plans
- Search for "solar buyback" plans from Texas REPs
- Compare buyback rates and terms carefully
- Watch for time-of-use rates that affect value
- Consider plans that offer 1:1 credit for excess
Major Utilities
Austin Energy
- Type: Municipal utility (regulated)
- Solar policy: Value of Solar tariff
- Rebates: Has offered solar rebates
- Battery incentives: Sometimes available
CPS Energy (San Antonio)
- Type: Municipal utility (regulated)
- Solar policy: Net metering available
- Rebates: Solar rebate program
- Good for solar: Generally supportive
Oncor (Transmission)
- Type: Transmission/distribution utility
- Role: Delivers power, doesn't sell it
- Your REP: Choose retail provider for buyback
- Interconnection: Oncor handles connection
Retail Electricity Providers
In deregulated areas, compare these providers for solar buyback plans:
- TXU Energy
- Reliant Energy
- Green Mountain Energy
- Chariot Energy
- Many others (shop around)
Texas-Specific Considerations
Extreme Weather
- Heat: Panels work in heat but lose some efficiency
- Hail: Quality panels withstand most hail; insurance covers damage
- Winter storms: Solar + battery provides backup during outages
- Hurricanes (coast): Proper installation and insurance important
Grid Reliability
After Winter Storm Uri (2021), many Texans are interested in energy independence:
- Solar alone: Shuts off during grid outages (safety requirement)
- Solar + battery: Provides backup power during blackouts
- Growing interest: Battery attach rates increasing in Texas
HOA Rules
Texas law protects your right to install solar, but HOAs can have some say:
- Cannot prohibit: HOAs cannot ban solar panels
- Can regulate: Placement preferences within reason
- Cannot reduce efficiency: Rules can't significantly reduce output
- Get it in writing: Document any HOA requirements
Property Tax Exemption
Texas offers a 100% property tax exemption for the added home value from solar panels. This is a significant benefit that effectively reduces your cost of ownership.
- Solar doesn't increase your property tax bill
- Applies to the value solar adds to your home
- Automatic—no application needed
The Bottom Line
Is Texas Good for Solar?
Texas is a solid solar market, especially if you:
- Find a good solar buyback plan from a retail provider
- Consider PPA/lease to access remaining federal incentives

- Have high electricity usage (common in Texas with AC)
Best Candidates for Texas Solar
- High electricity bills: $150+/month

Questions to Ask Installers
- What solar buyback plans work best with my address?
- How do you handle HOA approval?
- What's the expected payback period with current rates?
- Do you recommend battery storage for my situation?
- How does a PPA compare to purchasing in Texas now?
