Solar + Heat Pump + Battery Storage for Texas. One installer. One project. Grid independence. Cut summer electric bills 60-80%, replace your aging AC with a heat pump, and never worry about ERCOT again.
A full home electrification bundle in Texas -- solar panels, heat pump, and battery storage -- costs $42,000-$60,000 before incentives. After utility rebates, property tax exemption, and solar buyback income, effective cost drops to $38,000-$52,000. With Propel $0-down financing, you pay just 70% of system cost because a third-party owner claims the 30% commercial ITC. One installer handling all three components saves $3,500-$5,600 vs. hiring separate contractors. The biggest TX advantage: solar produces the most power exactly when your AC demand is highest -- perfect summer alignment.
Texas summers push electric bills to $300-$500/month. Your AC is the single biggest energy consumer. Each component solves a different problem. Together, they turn your home into its own power plant.
TX gets 1,400-1,600 kWh/kW annually -- among the best solar production in the US. Solar produces the most power during summer afternoons, exactly when your AC is running hardest. Perfect alignment.
A heat pump IS a high-efficiency AC that also heats. Replace your aging 10-13 SEER AC with a 16+ SEER2 unit. Save 25-35% on cooling costs immediately. The heating mode handles TX mild winters easily.
Winter Storm Uri. Summer ERCOT conservation alerts. Rolling blackouts. A battery keeps your heat pump and critical loads running when the grid fails. Solar recharges it during the day.
Charge battery from solar midday. Discharge during 4-7 PM peak pricing. With ERCOT TOU plans, this arbitrage saves $300-$600/year on top of direct solar offset savings.
ERCOT operates as an isolated grid -- Texas is not connected to the Eastern or Western Interconnection. When the grid fails, there is no backup from neighboring states.
4.5 million homes lost power for up to 5 days in freezing temperatures. Over 200 deaths. Pipes froze, families sheltered in cars. Solar + battery homeowners kept their heat pumps running through the entire event.
Every summer, ERCOT issues conservation appeals when demand exceeds generation capacity. Your battery discharges during these peaks, keeping your AC running while reducing grid strain. No more sweating through "voluntary conservation" requests.
Solar + battery = on-site generation + storage. During outages, solar charges your battery by day while powering your home. At night, the battery takes over. A 10 kW solar + 13.5 kWh battery can power a heat pump + essential loads for 12-24+ hours.
Texas has no single statewide program. Incentives come from individual utilities, property tax law, and REP solar buyback plans. The key is knowing which ones you qualify for.

If your current AC + furnace costs you $4,500/year and the bundle brings that to $800/year, you are saving $3,700/year. On a $51,000 bundle with Propel (paying $35,700), payback is under 10 years. After that, it is pure profit for the remaining 15+ years of equipment life.
Bundling all three components with one installer saves money on shared electrical work, permitting, crew mobilization, and project management.
| Component | Individual Install | Bundle Price | You Save |
|---|---|---|---|
| Solar (10 kW) | $27,000 | $25,500 | $1,500 |
| Heat Pump (4-ton ducted, 16 SEER2) | $12,000 | $11,000 | $1,000 |

Solar, heat pump, and battery are not three separate systems. When designed together, they create an integrated energy ecosystem perfectly tuned for the Texas climate.
TX solar production peaks 10 AM - 4 PM -- exactly when your AC runs hardest. Panels on your roof convert sunlight to electricity. Microinverters (Enphase IQ8) convert DC to AC at each panel.
Your heat pump draws from solar first. A 16 SEER2 heat pump uses 25-35% less electricity than your old AC. Powered by free solar electricity, your cooling costs approach $0 during sunny hours.
When solar produces more than your home and heat pump need (midday), excess energy charges your battery. Once full, surplus feeds to the grid for solar buyback credits from your REP.
ERCOT peak pricing hits 4-7 PM. Your battery discharges to power your home and heat pump, avoiding the most expensive grid electricity. TOU arbitrage saves $300-$600/year.
During blackouts, the battery powers your heat pump and critical circuits. Solar recharges the battery during the day. A 10 kW + 13.5 kWh system can sustain a home 12-24+ hours with careful load management.
In deregulated ERCOT territory, your REP pays for surplus production. Plans like TXU Solar Buyback credit you $0.06-$0.10/kWh for exported energy. $600-$1,800/year in buyback income.
Texas is a Propel financing state. A third-party system owner claims the Section 48 commercial ITC (30%), passing the savings to you. This is NOT a lease or PPA -- you own the system.

Important: Propel is a Concert Loan + Prepaid ESA. The third-party system owner (financing company) claims the Section 48 ITC -- not you, and not the installer. You own the system from day one. This is not a lease or PPA. Monthly payments are fixed for 25 years.
TX rebates vary dramatically by utility. Austin Energy and Oncor offer the largest bundle incentive stacks. Your delivery utility determines which rebates you qualify for.
| Utility | Solar Rebate | HP Rebate | Battery Rebate |
|---|---|---|---|
| Austin Energy | $2,500 | ~$3,000 | $2,500 |
| Oncor | -- | $600 | Up to $3,500 |
| CenterPoint | -- | ~$500 | -- |
| CPS Energy | Tiered | $100-$275/ton | -- |
Austin Energy is the big winner: Up to $8,000 in combined rebates for a full solar + heat pump + battery bundle. Oncor territory is second-best with up to $4,100 (mostly from the battery+solar rebate). CenterPoint and CPS territory have smaller incentives but benefit equally from property tax exemption and Propel financing.
TX is cooling-dominant with extreme summer heat (100F+), significant hail risk in north TX, and high humidity along the Gulf Coast. Equipment must handle these conditions.

TX is cooling-dominant -- SEER2 rating matters more than HSPF2. 16+ SEER2 units save 25-35% on cooling vs. old 10-SEER AC. Variable-speed compressor handles humidity.
Compare Heat PumpsBattery
PW3: 13.5 kWh / 11.5 kW continuous. IQ5P: 5 kWh modular. Both support ERCOT TOU arbitrage and whole-home backup during grid emergencies.
Battery OptionsDFW, Fort Worth, Plano, and north TX metro areas experience significant hail storms. Silfab 440W panels are UL 61730 hail-tested (2-inch ice at 52 mph). Enphase microinverters mean one damaged panel does not take down the whole array. Review your homeowners insurance policy to confirm solar panel coverage as an attached structure.
Most TX solar companies install panels only. Most HVAC contractors do heat pumps only. NuWatt installs all three as one coordinated project.
TX homes run 3-5 ton AC loads (30-50 amp circuits). Solar, heat pump, and battery all connect to your panel. One installer designs the full system together -- no capacity conflicts, no oversizing, no panel upgrade surprises.
Texas requires TDLR licensing for HVAC work. Having one company handle solar, HVAC, and electrical means all trades coordinate under one project plan. No scheduling conflicts between three separate contractors.
One building permit and one electrical permit instead of three separate applications. One inspection schedule. TX permit timelines are 5-10 business days for most jurisdictions.
If the battery stops charging from solar, or the heat pump circuit trips, one phone number handles everything. No finger-pointing between solar, HVAC, and electrical contractors.
A complete electrification project takes 6-8 weeks from contract signing to full operation. TX permitting is generally faster than Northeast states.
All three components designed together. Electrical load analysis (TX homes run 3-5 ton AC loads), roof assessment (checking for hail damage), Manual J heat load calculation.

Common questions about full home electrification in Texas.
A complete home electrification bundle in Texas -- solar panels, heat pump, and battery storage -- costs $42,000-$60,000 before incentives. After utility rebates (Oncor up to $4,100, Austin Energy up to $5,500), property tax exemption savings, and solar buyback income, effective cost drops significantly. With Propel $0-down financing, the system cost is reduced by 30% because a third-party owner claims the Section 48 commercial ITC. Federal residential credits (25D/25C) are expired as of 2026.
Yes. NuWatt installs all three components as a coordinated project in Texas. One installer designs the full electrical system (panel, solar, heat pump, battery) together, avoiding capacity conflicts and ensuring optimal sizing. You get one building permit, one inspection, and one project manager. Having one company handle everything simplifies the design, avoids finger-pointing between contractors, and eliminates duplicate electrical panel work.
Yes -- this is the key TX advantage. A heat pump is essentially a high-efficiency AC that can also heat. Since TX is 80% cooling / 20% heating, you are replacing your AC with a unit that does both jobs. A 16 SEER2 heat pump replaces a 10-13 SEER AC with 25-35% better cooling efficiency, saving $150-$300/month in summer. The heating mode handles TX mild winters easily (30-50F lows).
Texas homes with heat pumps typically need 8-12 kW solar systems (18-27 Silfab 440W panels). TX gets excellent solar production -- approximately 1,400-1,600 kWh per kW installed annually. A 10 kW system produces ~14,500 kWh/year, which covers both your existing usage and the heat pump load. Since the heat pump replaces your old AC (which already used significant electricity), the incremental electricity increase is modest -- roughly 1,500-3,000 kWh/year for the heating function.
Yes. A Tesla Powerwall 3 (13.5 kWh, 11.5 kW continuous) can run a heat pump for 4-8 hours during an outage. This matters enormously in Texas -- Winter Storm Uri (Feb 2021) left millions without power for days in freezing temperatures. During summer ERCOT conservation alerts, your battery keeps your AC running when the grid is stressed. During daytime outages, solar panels recharge the battery while simultaneously powering the heat pump.
Propel is a Concert Loan + Prepaid ESA financing structure available in TX. A third-party system owner claims the Section 48 commercial ITC (30% base), reducing your system cost by 30%. You pay 70% of the system cost at 8.99% APR over 25 years with $0 dealer fee and $0 down. Minimum 660 FICO, $10K-$135K loan range. Requires Silfab 440W panels (FEOC-compliant). Propel is NOT a lease or PPA -- you own the system.
Texas incentives are utility-specific rather than statewide. Solar: Austin Energy $2,500 rebate, Oncor battery+solar rebate up to $3,500, 100% property tax exemption, solar buyback income (REP-dependent). Heat pump: Austin Energy ~$3,000, Oncor $600, CenterPoint ~$500, CPS Energy $100-$275/ton. Battery: Oncor up to $3,500, Austin Energy $2,500, ERCOT TOU arbitrage savings. Federal credits (25D/25C) are expired. No state income tax means no state tax credits.
Yes. Bundling solar, heat pump, and battery with one installer saves $3,500-$5,600 compared to hiring separate contractors. Savings come from shared electrical work (one panel upgrade instead of multiple), one building permit, one crew mobilization, one design cycle, and one project manager. The electrical panel upgrade ($2,200 if done separately) is absorbed into the bundle at no extra cost.
Quality solar panels are tested to withstand 2-inch ice balls at 52 mph (UL 61730). Silfab 440W panels used in our bundles meet this standard. However, Texas does see extreme hail events exceeding test standards. Homeowners insurance typically covers hail damage to solar panels as an attached structure. We recommend reviewing your policy and considering endorsements for solar equipment. Enphase microinverters (panel-level) also mean one damaged panel does not take down the whole system.
ERCOT deregulation is actually an advantage for solar + battery owners. In deregulated areas (85% of TX), you choose your own REP (Retail Electric Provider) and can select solar buyback plans that pay you for excess production. With a battery, you can charge from solar during the day and discharge during expensive peak hours (4-7 PM), exploiting TOU rate differences. REPs like TXU Solar Buyback, Reliant, and Green Mountain offer various buyback structures. Austin Energy and CPS Energy (regulated) have their own buyback programs.
Solar + Heat Pump + Battery -- designed as one integrated system for Texas. Replace your AC, cut summer bills 60-80%, and never worry about the grid again. Propel $0-down financing available.
