Get a Free QuoteHouston solar panels cost $2.50–$2.90/W installed in CenterPoint Energy territory. A 10 kW system runs ~$27,000 gross with 5.2 peak sun hours per day producing 15,600 kWh/year. Section 25D is dead ($0 residential tax credit), but Section 48E lease/PPA options and Propel Solar offer $0-down paths. CenterPoint has no solar rebate — your savings depend on REP buyback plan choice and the property tax exemption.
2026 Alert: The federal residential solar tax credit (Section 25D) expired December 31, 2025. Houston homeowners who purchase solar with cash or a loan receive $0 in federal tax credits. All prices shown are full installed cost. The commercial ITC (Section 48/48E) is still available through lease/PPA or Propel Solar where a third-party owner claims the 30% credit. Construction must begin before July 4, 2026.
What a Houston homeowner actually pays for solar in 2026 — from equipment to installation to 25-year financial returns. Updated pricing reflects March 2026 market conditions.
Larger systems lower the $/W — a 12 kW system may be $2.55/W vs $2.85/W for a 6 kW system. Houston homes with high AC usage often benefit from 10-14 kW systems.
Two-story homes with steep pitches or tile roofs add $0.10-0.30/W. Many Houston ranch-style homes have ideal low-pitch asphalt roofs that keep installation costs low.
6-bolt rail mounting, stainless steel hardware, and wind-rated panels add $0.10-0.20/W but are recommended for Gulf Coast installations. Insurance may require it.
With Section 25D dead, how you finance solar matters more than ever. Two of these four options still access the 30% federal ITC through third-party ownership.
All figures based on a 10 kW system in CenterPoint territory at $2.70/W average, $0.16/kWh REP rate, 8.5¢ buyback via Green Mountain Energy.

The residential tax credit (25D) is dead, but the commercial ITC (Section 48/48E) lives on. When a third-party company owns your solar system, they claim the 30% credit and pass savings to you through lower lease or PPA payments.
A solar financing company (not your installer) purchases and owns the panels installed on your roof.
On a $27,000 system, that is $8,100 in tax credits plus accelerated depreciation benefits.
Instead of paying $27,000, you pay a fixed monthly amount that is typically 10-15% less than your current electric bill.
Lower monthly cost, protection from rate increases, and panels on your roof generating clean energy.
Fixed monthly payment ($110-$150/mo for 10 kW) regardless of production. You pay for the equipment, not the energy. Typical escalator: 1.5-2.9%/year. Ownership at end of 20-25 year term or buyout option.
You buy the electricity at a fixed rate (8-12 cents/kWh) instead of paying for equipment. If panels underperform, you pay less. In Houston at 16 cents/kWh, a 10-cent PPA saves 37% on solar-generated energy.
$0 down, fixed payment (~$155/mo vs $175 electric bill). Full ownership transfers by year 5 — unlike leases that take 20-25 years. Uses American-made Silfab 440W panels. Available in TX now.
The OBBBA (signed July 4, 2025) sunsets the commercial ITC for new projects not under construction by July 4, 2026. For Houston homeowners considering lease, PPA, or Propel financing, this means acting in Q1-Q2 2026. After this deadline, the only path to solar is cash or loan at full price with no tax credit of any kind. If you are considering third-party ownership, do not wait.
Propel is NuWatt's recommended financing path for Houston homeowners who want $0 down, immediate savings, and ownership in approximately 5 years — not 20-25 years like a traditional lease.
The financing company owns your system and captures the 30% Section 48E commercial ITC plus MACRS depreciation. That tax benefit funds your $0 upfront cost.
Your Houston CenterPoint electricity bill of ~$175/mo becomes a fixed ~$155/mo Propel payment — saving ~$$240/year from day one. No escalator. Predictable.
Full ownership transfers after ~5 years at no additional cost. Silfab 440W American-made panels with free maintenance during financing. You own the panels for 20+ remaining years.
CenterPoint offers $0 in solar rebates. The best REP buyback rate is 8.5 cents/kWh — well below retail. With 25D dead, a cash buyer gets zero credits on a $27,000+ system. Propel solves this by accessing the 30% commercial ITC that cash buyers cannot.
Unlike a 20-25 year lease where you never own the panels until the end, Propel transfers ownership by year 5. You get free electricity for the remaining 20+ years of the panel lifespan — which is where the real ROI lives.
Houston is in the deregulated ERCOT market. CenterPoint Energy delivers electricity to your home, but you choose your Retail Electric Provider (REP). Your solar economics depend on which REP buyback plan you select.
In CenterPoint territory, your REP determines how much you earn for exported solar energy. Choosing the right plan can save $500-$1,500 per year compared to a poor buyback rate.
| REP | Plan | Buyback Rate | Contract | Rollover |
|---|---|---|---|---|
| Green Mountain EnergyTop Pick | Pollution Free Solar Buyback 36 | 8.5¢/kWh fixed | 36 mo | |
| Chariot Energy | Solar Buyback 24 | 7.0¢/kWh fixed | 24 mo | |
| Constellation | Solar Buyback 12 | 6.5¢/kWh fixed | 12 mo | |
| Shell Energy | Solar Buyback 24 | 6.0¢/kWh fixed | 24 mo | |
| Pulse Power | Solar Buyback 12 | 5.5¢/kWh fixed | 12 mo | |
| Rhythm Energy | Solar Buyback | Wholesale (variable) | Month-to-month |
Your 10 kW system produces ~15,600 kWh/year. You self-consume about 70% (10,920 kWh), saving 16¢/kWh. The remaining 30% (4,680 kWh) is exported and credited at your REP's buyback rate. At Green Mountain's 8.5¢, that is ~$398/year in export credits. At Shell's 6.0¢, it drops to ~$281/year — a $117/year difference on the same system.
No, you have one REP at a time. But you can switch REPs when your contract expires. Strategy: Start with a high buyback plan (Green Mountain 36-month), then switch to whatever has the best rate when your contract ends. Check powertochoose.org quarterly for new offers.
TXU Energy's popular retail-match solar buyback plan (which provides effective 1:1 net metering) is only available in Oncor territory (Dallas-Fort Worth). Houston homeowners in CenterPoint territory cannot access this plan. The best fixed-rate option for Houston is Green Mountain Energy at 8.5 cents per kWh.
After Hurricane Beryl (July 2024) left 2.7 million CenterPoint customers without power for up to 12 days, Houston solar+battery adoption surged. Solar alone shuts down during grid outages — a battery is essential for hurricane protection.
Standard panels: 140 mph. Premium panels (REC, Silfab): 180+ mph. Houston building code requires wind resistance for the local design speed. A proper rack mount matters more than the panel rating itself.
6-bolt rail mounting systems (vs standard 4-bolt) reduce uplift risk during hurricanes. Adds $0.05-0.10/W but strongly recommended for Gulf Coast homes. Stainless steel lag bolts resist corrosion.
Most Houston homeowners insurance covers solar panels as part of the dwelling. Confirm your policy covers full replacement cost. Some insurers offer discounts for wind-rated mounting systems. Annual premium increase is typically $10-30/month.
Without a battery, grid-tied solar panels shut off during a power outage (anti-islanding protection). During Hurricane Beryl, solar-only homes had no power. Solar+battery homes ran AC, refrigerators, and essential circuits for days.
Tesla Powerwall 3 and other smart batteries detect incoming storms via weather data and auto-charge to 100% before the hurricane arrives. Your battery is fully charged when the power goes out.
Beyond hurricane protection, batteries enable peak shaving during ERCOT heat waves when wholesale prices spike. Some REPs offer time-of-use rates where batteries shift solar export to highest-value hours.
| Battery | Capacity | Backup | Installed Cost | Warranty |
|---|---|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh | 12-18 hrs (essentials) | $9,500-$12,000 | 10-year |
| Enphase IQ Battery 5P | 5 kWh (stackable) | 4-8 hrs per unit | $7,000-$9,000 | 15-year |
| Franklin WH aPower2 | 13.6 kWh | 12-20 hrs | $10,000-$13,000 | 12-year |
| SonnenCore+ | 10 kWh | 8-14 hrs | $8,500-$11,000 | 10-year |
Houston averages 75-80% relative humidity. High humidity scatters sunlight, reducing direct irradiance by 3-5%. Afternoon convective clouds further reduce clear-sky hours. Net impact: ~5-8% less production vs arid West Texas.
Within 15 miles of Galveston Bay or the Gulf, salt air accelerates corrosion. Choose panels with IEC 61701 salt mist certification and marine-grade aluminum or stainless steel mounting hardware.
No. Houston still receives 5.2 peak sun hours per day, well above the national average of 4.5. The humidity and hurricane factors are manageable with proper equipment choices. Thousands of Houston homes already have solar producing reliable savings.
The key is choosing an experienced Gulf Coast installer who uses appropriate mounting hardware and corrosion-resistant materials. Adding a battery ($7,000-$13,000) provides hurricane resilience and turns solar from a savings play into an essential resilience investment.
Harris County has one of the highest property tax rates in Texas. The 100% solar property tax exemption is the single largest financial incentive for Houston solar owners in 2026.
After your solar installation is complete, file Form 50-123 (Exemption Application for Solar or Wind-Powered Energy Devices) with the Harris County Appraisal District by April 30 of the year following installation. This is NOT automatic — you must file separately from your homestead exemption. The exemption ensures your property taxes do not increase due to the added value of your solar system. At Harris County's 2.31% rate, this is worth $624 per year in the first decade alone.
Solar adoption varies across Houston's sprawling metro area. Here is what to expect in the most active neighborhoods.
High home values, large roofs, strong HOA compliance rates
New construction friendly, modern electrical panels
High adoption rate, Fort Bend County 2.29% tax rate
Growing solar adoption, competitive installer access
Coastal area: salt air considerations, higher wind ratings needed
Older homes, may need panel/roof upgrades
| City | $/W | Rate | Utility | Rebate | Payback |
|---|---|---|---|---|---|
| Houston | $2.50-$2.90 | ~16¢/kWh | CenterPoint | $0 | 10-12 yrs |
| Dallas | $2.50-$2.90 | ~15¢/kWh | Oncor | $0 | 10-12 yrs |
| Austin | $2.50-$2.90 | ~12¢/kWh | Austin Energy | $2,500 | 8-10 yrs |
| San Antonio | $2.45-$2.85 | ~12.5¢/kWh | CPS Energy | Limited | 9-11 yrs |

Estimates based on average 2026 TX solar pricing, 5.3 peak sun hours/day, 0.5%/year panel degradation, 3%/year electricity rate increase, and TX property tax exemption (Tax Code §11.27). Actual costs vary by installer, roof condition, and system configuration. Section 25D residential ITC expired Dec 31, 2025 — $0 federal tax credit for cash/loan purchases.
The calculator reflects $0 federal tax credit for cash and loan purchases. Section 25D expired December 31, 2025. Lease/PPA or Propel Solar access the 30% commercial ITC (Section 48/48E) through third-party ownership. Construction must begin before July 4, 2026.
The Texas property tax exemption at Harris County's 2.31% rate saves $11,850 over 25 years on a $27,000 system. This is the single largest incentive for Houston solar owners and is factored into the savings estimate.
