Solar Panel Costs and Savings in Texas (2026 Guide)

Texas has a genuinely unique electricity landscape — a deregulated retail market and its own ERCOT grid — both of which shape how solar savings actually work for Texas homeowners.

The deregulated market changes how you shop for solar buyback

Unlike states with a single regulated utility and a mandated net metering policy, most of Texas operates under a deregulated retail electricity market, meaning homeowners choose their own retail electricity provider from a competitive market. This means solar buyback terms (compensation for excess exported electricity) vary by provider and specific plan, rather than being set by a single statewide net metering mandate — see our net metering guide for the general concept, then compare specific solar buyback plans across providers serving your area, since a plan built for solar customers can meaningfully change your effective savings.

No state income tax means no state tax credit

Texas has no state income tax, so there’s no state-level income tax credit for solar, similar to Nevada and Florida among our state guides. Texas does offer a property tax exemption for the added value of a solar installation, meaning your property taxes shouldn’t increase solely due to adding solar — a real, if more modest, state-level benefit alongside the federal tax credit.

ERCOT grid reliability and battery interest

Texas operates its own electric grid through ERCOT, largely independent from the two major interconnections covering the rest of the continental U.S. Following some high-profile grid reliability events in recent years, many Texas homeowners have shown increased interest in pairing solar with battery storage specifically for backup power during outages — a consideration separate from, but complementary to, the pure financial payback calculation.

Solid sun hours across most of the state

Texas has solid average sun hours, particularly in the western and southern parts of the state, supporting strong solar production relative to system size — run your own numbers with our calculator.

Bottom line

Texas’s deregulated electricity market means shopping for the right retail provider and solar buyback plan matters as much as the installation itself, and growing interest in grid reliability has made battery-paired systems increasingly common. No state income tax credit exists, but the property tax exemption and federal credit still support a solid financial case in a state with generally strong sun hours.
