In this explainer

Texas has some of the cheapest electricity in the country at about $0.155/kWh, and no statewide net-metering mandate. So how long does a 2026 cash solar system in Houston actually take to pay off? About 14.0 yrs.

What changed for 2026

Start with the federal change, because it moves the whole calculation. the federal residential solar credit (Section 25D) expired for systems purchased with cash in 2026; a lease or PPA may still capture 30 percent through the Section 48E commercial credit. That is why a 2026 cash payback in Houston reads differently than a year ago. This is general information, not advice.

The Houston system and what it costs

A typical Houston system is about 9.2 kW. As a 2026 cash purchase it runs around $26,680, because the federal residential credit no longer applies to a cash buy. Through a lease or power-purchase agreement that captures the 30 percent commercial credit, the comparable basis is closer to $18,676 - a different ownership path, not the cash price.

Why cheap power slows the payback

Here is the Texas wrinkle. Texas offers no dedicated state solar credit (0%), and on net metering the rule is no statewide mandate - export credit depends entirely on your retail provider plan. With a low electricity rate of about $0.155/kWh, each offset kilowatt-hour is worth less, which lengthens the math.

How to read your payback

Here is the honest 2026 picture for Houston. As a cash purchase with no federal credit, the payback is about 14.0 yrs. Through a lease or PPA that captures the 30 percent commercial credit, it is closer to 9.8 yrs. Cheap power and no statewide mandate are what stretch the cash timeline.

Frequently Asked Questions

Does Texas require utilities to offer net metering?

No. Texas has no statewide net-metering mandate, so what you earn for exporting solar power back to the grid depends entirely on your retail electricity provider and the specific plan you choose. Some providers offer generous buyback or solar-friendly plans, while others credit exports at a low avoided-cost rate or not at all. Because of this, two Houston homeowners with identical systems can see very different payback periods. Comparing provider buyback terms matters as much as the hardware. This is general information, not advice.

Why does cheap electricity make solar take longer to pay off in Texas?

Solar saves you money by replacing power you would otherwise buy from the utility, so the value of each kilowatt-hour your panels produce is tied directly to your electricity rate. When power is cheap, as it is across much of Texas, each unit of solar generation offsets a smaller dollar amount, so it takes more years of savings to recover the upfront system cost. Higher-rate states recover that cost faster even when hardware prices are similar.
