How long is solar payback in Texas?

Solar payback in Texas typically runs 7–12 years depending on your electricity rate, system size, sun hours, and whether you qualify for the federal 30% Investment Tax Credit plus any Texas state incentives. Use the calculator above for a personalized estimate.

What solar incentives are available in Texas in 2026?

All Texas homeowners qualify for the federal 30% Solar Investment Tax Credit (ITC) on the gross system cost. Texas may also offer a state tax credit, rebates from your utility, or favorable net metering. See the calculator inputs above for Texas-specific values.

Is net metering available in Texas?

Net metering rules vary by state and utility. Texas has its own rules — full retail credit, time-of-use rates, or buyback programs. The calculator above factors in Texas's effective net metering value when estimating your monthly bill offset.

How many sun hours does Texas get?

Texas's average peak sun hours per day (NREL TMY3 data) determines how much solar your system can generate. The calculator above uses Texas-specific irradiance to size the system from your monthly electricity bill.

Should I buy solar panels or lease them in Texas?

Buying outright (cash or loan) lets you claim the 30% federal ITC and any Texas state credit, and you own the energy. Leasing or PPAs let the installer take the credit but you avoid upfront cost. For long-term value in Texas, ownership almost always wins.

Solar Payback in Texas (2026) — High Sun, No State Credit

Texas has some of the best solar conditions in the country — 5.3 daily peak sun hours on average (top quartile nationally) — but a deregulated electricity market that makes solar economics highly dependent on which retail electric provider (REP) you choose. There’s no Texas state solar income tax credit. The federal 30% ITC is the main incentive, plus a property tax exemption that prevents your solar system from increasing your assessed home value.

Use the calculator below — your state is already selected. Adjust your monthly electric bill and system cost for a Texas-specific payback estimate.

How Texas solar buyback works

Texas doesn't have statewide net metering. Instead, each retail electric provider (REP) sets its own 'buyback' rate for excess solar exported to the grid. Major variations:

Green Mountain Energy: 1-to-1 buyback (full retail rate) for excess exports — best for solar economics
Octopus Energy: Solar Plan with 1-to-1 buyback up to monthly net-zero
Reliant Solar Payback: ~$0.06-0.08/kWh credit (wholesale-style)
TXU Renewable Buyback: avoided-cost rate, typically $0.06/kWh
Municipal utilities (Austin Energy, CPS San Antonio): Value-of-solar tariffs or full retail net metering

Before installing solar, switch to a REP with strong solar buyback. The difference can extend payback by 3-5 years.

Texas property tax exemption for solar

Texas Code 11.27 provides a 100% property tax exemption for residential solar PV systems — meaning your solar installation doesn't increase your assessed home value or property tax bill. With Texas's 1.74% effective property tax rate, this exemption saves homeowners $300-$500/year on a typical residential solar system. File Form 50-123 with your county appraisal district.

What 2026 Texas solar economics look like

A typical 7 kW solar system in Texas 2026:

Gross system cost: $19,600 ($2.80/W)
Federal 30% ITC: -$5,880
Net cost: $13,720
Annual production: ~13,500 kWh (Texas sun is excellent)
Annual savings at $0.14/kWh, 75% net metering value: ~$1,418
Simple payback: ~9.7 years

Same system on a REP with 100% buyback (Green Mountain, Octopus): annual savings ~$1,890, payback ~7.3 years. The REP choice is worth ~2-3 years of payback time.

How to use the Texas solar calculator above

The state is pre-selected. Adjust if needed.
Enter your typical monthly electric bill (averaged across the year).
The calculator auto-fills your state's average electricity rate and peak sun hours — override the electricity rate with your real $/kWh from your bill if you know it.
Adjust the system cost per watt based on quotes from local installers. Texas averages are typically within the $2.50–$3.50/W range for cash installs.
The output shows estimated system size, net cost after federal and state credits, year-1 savings, and 25-year cumulative savings.
