Houston sits in one of the strongest solar markets in the country. More than 200 days of usable sunshine per year, electricity rates that keep climbing, and a deregulated energy market that lets homeowners shop for the best buyback plans, all of it points toward solar making real financial sense for most residential properties in the Greater Houston area.
Most “best solar companies” lists rank installers without explaining why. That makes it difficult for homeowners to assess whether the ranking reflects anything beyond advertising spend. We approached this differently.
No company paid for placement on this list. Suntria is featured as our top recommendation based on the evaluation criteria above, and is a partner of this publication.

Sunrun is the largest residential solar company in the United States by installation volume, and their Houston operation benefits from that scale. The primary advantage of working with Sunrun in 2026 is their lease and PPA product because Sunrun owns the system under these arrangements, they claim the commercial investment tax credit (Section 48E) and pass savings to the homeowner through reduced monthly rates.
Best for: Homeowners who want lease or PPA structures that still capture federal tax credit value through third-party ownership, and who prefer a fully managed service model.
Years in business: 5+
Key equipment: Various tier-one and mid-tier panels; Enphase microinverters

Solar Houston Solutions serves both residential and commercial clients, which makes them a practical choice for small business owners who also want solar on their home, or property investors managing multiple buildings. Their commercial experience translates to an understanding of structural engineering requirements, utility-scale interconnection, and permitting workflows that purely residential installers rarely encounter.
Best for: Business owners and property investors who want one installer for both commercial (where the federal tax credit still applies) and residential projects.
As of early 2026, the average cost of a residential solar installation in Houston falls between $2.16 and $2.84 per watt, depending on equipment quality and system size. For context, the national average sits around $3.03 per watt, so Houston pricing is competitive.
At current pricing, here is what Houston homeowners can expect to pay before incentives:
8 kW system: $17,280 to $22,720
10 kW system: $21,600 to $28,400
12 kW system: $25,920 to $34,080
14 kW system: $30,240 to $39,760
These figures are the full installed cost, including panels, inverters, mounting hardware, electrical work, permitting, and CenterPoint Energy interconnection. They do not include battery storage, which adds $10,000 to $16,000 for a system like the Tesla Powerwall or Enphase IQ Battery.
Texas requires solar installers to hold an active electrical contractor license through the Texas Department of Licensing and Regulation (TDLR). Verify this before signing any contract. It's searchable on the TDLR website. Beyond the state license, look for NABCEP certification.
Warranty Coverage
Solar warranties have three layers, and most homeowners only pay attention to one. The panel manufacturer warranty covers the modules themselves, typically guaranteeing production at or above 80–85 percent of rated capacity for 25 to 30 years.
Financing Options
The expiration of the federal residential tax credit fundamentally changed the financing calculus for Houston homeowners. When the 30 percent ITC was available, cash purchases offered the clearest return because the buyer claimed the full credit directly. In 2026, the math is different.
Third-party ownership models solar leases and power purchase agreements have become more attractive because the company that owns the system can still claim the commercial investment tax credit (Section 48E) through 2027 and pass those savings to the homeowner in the form of lower monthly payments.
The equipment your installer puts on your roof matters for long-term performance. Tier-one panel manufacturers including Silfab, REC, Q Cells, Canadian Solar, and SunPower have the financial stability and manufacturing quality control to honor 25-year warranties. Less established brands may offer lower upfront pricing but carry more risk if the manufacturer exits the market before your warranty period ends.
A solar system is a 25 to 30-year asset. The company you choose needs to be available for monitoring, maintenance, and warranty claims over that entire period. Ask prospective installers whether they provide a monitoring platform (most integrate with Enphase or SolarEdge apps), how they handle warranty claims, and whether they have a dedicated service team for post-installation support. Companies that subcontract installation and have no local service presence are riskier long-term partners than those with Houston-based operations teams.
The incentive landscape for residential solar changed substantially at the start of 2026. Here is what is and is not available to Houston homeowners right now.
The Residential Clean Energy Credit commonly known as the solar ITC expired on December 31, 2025, following the passage of the One Big Beautiful Bill Act signed on July 4, 2025. Previously, homeowners who purchased and owned their solar systems could claim 30 percent of the total installation cost as a federal tax credit. That benefit is no longer available for systems installed in 2026 or later. If you installed a system before the deadline and have not yet filed your 2025 taxes, you can still claim the credit on your return.
While homeowners can no longer claim a federal credit directly, the commercial solar tax credit remains available through the end of 2027. This matters for residential solar because third-party ownership structures, leases and PPAs qualify under this provision.
Texas Property Tax Exemption: Active
Texas law provides a 100 percent property tax exemption on the added value of a solar energy installation. Solar panels typically increase a home’s market value by approximately 4 percent, and in a state with one of the highest property tax rates in the country (averaging 1.6 percent), this exemption saves Houston homeowners an estimated $400 to $600 per year for the life of the system. Over 25 years, that adds up to $10,000 to $15,000 in avoided property taxes. To claim the exemption, file Form 50-123 with your county appraisal district by April 30 of the tax year following installation.
Texas does not have a statewide net metering mandate, but Houston’s deregulated energy market gives homeowners the ability to shop for retail electric providers that offer solar buyback plans.
Local Utility Rebates
Some Texas utilities offer direct rebates for solar installations, though availability is limited in the Houston area. Oncor’s Solar PV Standard Offer Program provides rebates for customers in its service territory, and Austin Energy offers $2,500 for residents in its coverage area. For most Houston homeowners served by CenterPoint Energy, utility rebates are not consistently available, making the property tax exemption and solar buyback programs the primary financial incentives in 2026.
This is the question that matters most, and the answer in 2026 is more nuanced than it was a year ago.
The end of the federal residential solar tax credit marks a real shift in the economics of going solar in Houston, but it does not make solar a bad investment. Texas’s property tax exemption, competitive retail electricity buyback plans, and the continued availability of the commercial tax credit through third-party ownership structures mean that most Houston homeowners can still achieve meaningful savings. The path to those savings just looks different than it did in 2025.
The average Houston home uses about 1,574 kWh per month, which typically requires a 10 to 14 kW system to offset most or all of that consumption
Who is the highest-rated solar company in Houston?
Among the companies on this list, SolRa Tech holds the highest Google review rating at 5.0 stars from over 140 reviews. However, ratings should be considered alongside volume, longevity, and warranty terms.
Do solar panels increase home value in Texas?
Yes. Research consistently shows that solar panels increase residential property values by approximately 4 percent. In Houston, where the median home value exceeds $250,000, that represents roughly $10,000 or more in added equity.
What happens to solar panels during a Houston hurricane?
Modern solar panels are engineered to withstand wind speeds of 140 mph or higher, which covers Category 4 hurricane conditions. Most Houston installations use flush-mounted racking systems that sit close to the roof surface, minimizing wind uplift. The greater risk during severe weather comes from flying debris, which can damage individual panels.
Texas does not mandate net metering at the state level, but Houston’s deregulated energy market means many retail electricity providers voluntarily offer solar buyback plans. Under these plans, you earn credits for excess energy your system sends to the grid, which offset your electricity costs when your panels are not producing (nighttime, cloudy days).
