Austin has the best solar economics in Texas — a $2,500 rebate and 9.91 cents/kWh Value of Solar. But the federal ITC expired. The company you choose determines whether you capture every available dollar or leave money on the table.
Austin is still the best Texas city for solar. But one major change reshapes how you should buy.
The residential solar ITC (Section 25D) expired December 31, 2025. Cash and loan buyers get $0 from the IRS. Only third-party-owned systems access Section 48.
Austin Energy still offers a flat $2,500 residential solar rebate — the only major municipal solar rebate left in Texas. Must use an approved contractor.
The Value of Solar tariff is currently 9.91 cents per kWh but is recalculated annually. It has declined from 11.3 cents in 2015. Lock in solar now before it drops further.
Ask every solar company these seven questions. If they cannot answer all of them, keep looking.
Ask: “Will I own the panels?”
Solar leases and PPAs mean someone else owns your panels for 20-25 years. You are renting your own roof and cannot claim property value increases.
Propel: a third-party owner holds the system for 5 years to capture the commercial ITC, then full ownership transfers to you. By year 5, the panels are yours. No buyout. No escalator. No landlord on your roof.
In Austin, ownership matters even more because solar adds significant property value — studies show $20 per $1 of annual energy savings. Austin's strong housing market means owned solar panels increase your home equity. Leased panels complicate real estate transactions.
Ask: “Does my payment increase over time?”
Many solar leases include 2-3% annual escalators. A $120/month payment becomes $180/month by year 15 and $217/month by year 20.
Propel: $126/month fixed for the entire financing period. No escalators. Period. Your Austin Energy bill goes up year after year — your solar payment stays exactly the same.
Austin Energy rates have increased steadily as the city invests in grid upgrades and renewable targets. A fixed solar payment at $126/month creates a widening savings gap compared to a rising utility bill.
Ask: “How do I get the tax credit if 25D expired?”
If you buy solar with cash or a loan in 2026, you get $0 in federal tax credits. The residential Section 25D credit expired December 31, 2025.
Propel uses a Section 48/48E hybrid structure. The third-party system owner claims the 30% commercial ITC for projects beginning construction before July 4, 2026. Those savings flow to you as a lower monthly payment — on top of the $2,500 Austin Energy rebate.
Austin is unique: the $2,500 local rebate stacks with Propel's Section 48 structure. Cash buyers get the rebate but lose the federal credit. Propel customers get both — the rebate reduces gross cost, and the Section 48 credit reduces the monthly payment.
Ask: “Where are the panels manufactured?”
Most budget installers use Chinese-manufactured panels. These panels do not qualify for FEOC (Foreign Entity of Concern) bonus credits and face potential tariff increases.
Propel requires Silfab 440W panels — manufactured in the USA. FEOC-compliant. 25-year product warranty, 30-year performance warranty. Rated for Texas heat and hail.
Austin Energy's approved contractor list ensures quality installations, but it does not mandate panel origin. FEOC compliance is a separate requirement for the Section 48 bonus credit. Make sure your installer uses qualifying panels to maximize the financing benefit.
Ask: “What happens if something breaks?”
Many installers offer 10-year workmanship warranties or rely solely on manufacturer warranties. If the installer goes out of business, you are on your own.
Propel includes 25-year Silfab panel warranty + 25-year Enphase IQ8 microinverter warranty. Free maintenance during the financing period. After ownership transfer, manufacturer warranties continue.
Austin averages 5-7 hail events per year and summer temperatures regularly exceed 100 degrees Fahrenheit. Enphase microinverters handle heat better than string inverters. Silfab panels carry hail certification. Cheap equipment with short warranties is a false economy in Central Texas.
Ask: “Can I visit their office?”
National door-to-door companies have no local office, no local service team, and no accountability. FTC solar complaints increased 700% from 2020-2024. The Maine Attorney General sued three national solar companies — the same brands operate in Texas.
Choose a company with a physical Texas presence, verified TDLR electrical contractor license, and local installation crews. Bonus: confirm they are on Austin Energy's Approved Solar Contractor list.
Austin has a robust local solar market, but national companies are aggressively door-knocking in 78701-78759 ZIP codes. Always verify Austin Energy approved contractor status — without it, you forfeit the $2,500 rebate. Check TDLR for the Texas electrical contractor license.
Ask: “Is my system sized for the VoS tariff?”
Undersized systems miss daytime production potential. Oversized systems export more than needed — VoS credits expire at year-end, so unused credits are lost.
The right installer sizes your system to cover 100-110% of annual usage, maximizing self-consumption at 12 cents per kWh while earning 9.91 cents on exports through the VoS tariff.
Austin's VoS rate of 9.91 cents per kWh is generous compared to CPS Energy (3-4 cents) or deregulated market buyback rates (3-8.5 cents). This means moderate oversizing is acceptable in Austin — unlike San Antonio where you sell at a 70% discount. But credits still expire in December, so do not oversize beyond your annual usage.

Austin is the only major Texas city where Propel customers get triple stacking: the $2,500 Austin Energy rebate + Section 48 commercial ITC + Value of Solar export credits at 9.91 cents per kWh. In San Antonio, Dallas, and Houston, the rebate and VoS components do not exist.
The best solar company in Austin in 2026 is on the Austin Energy Approved Solar Contractor list (required for the $2,500 rebate), offers panel ownership rather than a lease, uses FEOC-compliant American-made panels, provides fixed monthly payments with no escalator clauses, and understands the Value of Solar tariff to optimize your system sizing. NuWatt Energy meets all seven criteria through its Propel Solar program: $0 down, $126/month fixed, full ownership by year 5, Silfab 440W FEOC panels, and 25-year warranties.
Yes. Austin Energy offers a flat $2,500 residential solar rebate. This is the only major municipal solar rebate remaining in Texas. To qualify, you must be an Austin Energy customer and your system must be installed by an Austin Energy-approved contractor. The rebate can stack with Propel financing — the rebate reduces your upfront net cost, and Propel handles the rest with $0 down and fixed payments. Availability is subject to annual program budget, so confirm current funding status before signing a contract.
Yes. Austin has the best solar economics in Texas even without the residential ITC. The combination of the $2,500 Austin Energy rebate, the Value of Solar tariff at 9.91 cents per kWh for exports, and strong 5.5 peak sun hours makes Austin solar payback 6-8 years. Through Propel Solar, a third-party owner can also claim the 30% commercial ITC (Section 48/48E) for projects beginning construction before July 4, 2026, further reducing your fixed monthly payment to approximately $126/month — about 10% less than a typical $140/month Austin Energy bill.
Austin Energy pays 9.91 cents per kWh for all exported solar energy through the Value of Solar (VoS) tariff. This is NOT net metering — you buy electricity at full retail (approximately 12 cents per kWh) and sell excess at the VoS rate. Credits roll over month to month but expire at the end of the calendar year. The VoS rate is recalculated annually based on avoided energy costs, capacity value, environmental benefits, and fuel cost savings. At 9.91 cents per kWh, Austin has the most generous export credit of any major Texas utility.
