Quick Answer
Houston solar works well with 204 sunny days and 4.5 peak sun hours (NOAA data). The deregulated Texas market is both opportunity and challenge—you must choose a retail electricity provider (REP) with good solar buyback rates. Expect $2.40-3.00/watt and 9-13 year paybacks. Texas property tax exemption applies; no state income tax means no state credit.
Solar in Houston
Houston is Texas's largest city and offers solid solar potential. According to NOAA data, Houston averages 204 sunny days annually. While not as sunny as West Texas, Houston still gets plenty of sunshine to make solar worthwhile, especially given rising electricity costs.
From my experience:Houston's deregulated electricity market is both a blessing and a headache. The good news: you can shop around for a retail electricity provider with solid solar buyback rates. The bad news: you have to shop around, and many REPs either don't buy back solar at all or offer terrible rates. Don't sign with an installer until you've figured out which REP you'll use—that decision affects your entire payback calculation.
Houston Solar Stats
Houston averages 204 sunny days and 4.5 peak sun hours daily. A typical 8 kW system produces 10,000-11,000 kWh annually—enough to significantly offset most households' electricity usage. (Source: NREL Solar Resource Data)

Why Houston is Good for Solar
- Deregulated market: Choose your electricity provider
- Net metering alternatives: Some providers buy back excess
- Rising rates: Electricity costs trending up in Texas
- Property tax exemption: 100% of solar value excluded
- No state income tax: No state tax benefit, but no penalty either
Houston Solar Costs
Average System Costs
| System Size | Gross Cost | After Incentives* |
|---|---|---|
| 6 kW | $15,000-18,000 | $15,000-18,000 |
| 8 kW | $20,000-24,000 | $20,000-24,000 |
| 10 kW | $25,000-30,000 | $25,000-30,000 |
*Federal 25D credit ended Dec 31, 2025. PPA/Lease options still benefit from 30% through 2027.
Cost Per Watt
- Houston average: $2.50-3.00 per watt
- Budget installs: $2.20-2.50 per watt
- Premium installs: $3.00-3.75 per watt
Deregulated Market
Houston's deregulated electricity market means you can choose your retail electricity provider (REP), but CenterPoint remains the distribution utility. This creates both opportunities and complexity for solar.
How It Works
- CenterPoint: Delivers power, maintains grid, handles interconnection
- REP (Retail Electric Provider): You choose; bills you for usage
- Solar excess: Some REPs buy back, others don't
- Key factor: Choose an REP with good solar buyback policy
Finding Solar-Friendly REPs
Not all retail electricity providers buy back solar excess at good rates. Look for providers specifically offering solar buyback plans with competitive rates for excess generation. (Source: EIA Electric Power Monthly)
REP Solar Options
| Approach | How It Works | Best For |
|---|---|---|
| Solar buyback plan | REP credits excess at set rate | Overproducers |
| Time-of-use plan | Higher rates when you need it | Self-consumers |
| Standard plan | No export credit | High daytime usage |
Texas Incentives
Available Incentives
- Property tax exemption: 100% of solar value excluded
- No sales tax: On solar equipment purchases
- Some utility rebates: Check local programs
- No state tax credit: Texas has no income tax
Federal Options
- Purchased systems: No federal credit (25D ended 2025)
- PPA/Lease: Still benefits from 30% credit through 2027
- Consideration: PPA may be more attractive given no federal credit for purchases
Houston Considerations
Climate Factors
- Humidity: Can reduce production slightly, self-cleaning in rain
- Hurricanes: Proper installation withstands most storms
- Flooding: Ground-mount may need elevation consideration
- Heat: Summer heat reduces efficiency slightly
Houston-Specific Factors
- HOAs: Texas law protects solar rights, but check guidelines
- Roof types: Mix of asphalt shingle and tile; both work
- Permitting: Varies by municipality within greater Houston
- Tree coverage: Many neighborhoods heavily shaded
Production Estimates
- Annual production: 1,300-1,400 kWh per kW installed
- 8 kW system: ~10,400-11,200 kWh/year
- Best months: April-June, September-October
- Summer reality: Good production but heat reduces efficiency
Hurricane Resilience
Modern solar installations in Houston are designed to withstand high winds. Most panels are rated for 140+ mph winds. Adding battery storage provides backup power during outages. (Source: manufacturer specifications and EnergySage data)
The Bottom Line
Houston offers solid solar potential with unique market dynamics. The deregulated market means you need to choose your electricity provider carefully, but solar can significantly reduce bills and provide resilience during outages.
Key points:
- Choose a retail electric provider with good solar buyback rates
- Property tax exemption protects your home value increase
- Consider battery storage for hurricane season resilience
- PPA/Lease options may be attractive given no federal credit for purchases
- Expect 7-10 year payback depending on system and REP choice
