Texas sunshine can generate serious electricity, but installing panels is not simply a matter of covering a roof and waiting for the bills to fall. Hail, extreme summer heat, utility buyback rates, roof condition, battery requirements and long-term servicing can all affect the actual value of a home solar system.
Homeowners must also examine the company behind the equipment. A strong installer should provide realistic production estimates, licensed electrical work, transparent financing, dependable workmanship warranties and support after the system is activated.
The following companies were selected after reviewing their current Texas operations, service areas, installation processes, battery options, warranties, electrical licences and official company information. This is an editorial list rather than a price ranking because system costs and savings depend on the property, electricity usage, roof design and local utility.
1. Freedom Power
Freedom Power, previously widely known as Freedom Solar Power, is one of the most established home-energy companies operating in Texas. Founded in 2007, the company has expanded beyond rooftop solar to provide battery storage, backup generators, EV charging and HVAC services.
A significant advantage is its integrated operating model. Freedom Power states that its design, permitting, installation and maintenance work is handled by its own team rather than being passed among unrelated contractors. It serves customers through offices in Austin, Dallas–Fort Worth, Houston and the San Antonio area.
The company installs panels from manufacturers such as Maxeon, Qcells, REC and Mission Solar. Its solar package includes a 25-year workmanship warranty, while the panels it offers carry manufacturer product and performance protection of at least 25 years. Battery choices can include Tesla Powerwall and Enphase equipment.
Why Freedom Power is good for Texas homeowners: Its in-house installation structure, multiple Texas offices and combination of solar, battery, generator and home-energy services make it suitable for customers who want one company to manage a larger energy project.

2. TriSMART Solar
TriSMART Solar is a Houston-based residential solar installer with one of the widest published service footprints in Texas. Its service areas include Austin, Dallas–Fort Worth, El Paso, Houston, Lubbock, McAllen, Midland–Odessa and San Antonio.
The company reports that Solar Power World ranked it as the leading residential installer in Texas and seventh among residential installers nationally. Its website also reports more than 17,000 completed projects. TriSMART holds Texas Electrical Contractor Licence TECL 32259.
TriSMART manages system design, site assessment, installation, HOA coordination, permitting and the utility permission-to-operate process. Battery storage options include products from Tesla, SolarEdge, FranklinWH and EcoFlow, allowing customers to add backup power instead of installing a solar-only system.
Why TriSMART Solar is good for Texas homeowners: Its broad statewide coverage is useful for residents outside the four largest metropolitan areas. It is also worth considering for customers who want solar panels, battery storage and utility activation managed through a single project team.

3. Good Faith Energy
Good Faith Energy was established in Addison, Texas, in 2014. It provides residential and commercial solar, battery backup, Tesla Solar Roof installation, EV chargers, roofing, solar repairs and ongoing system maintenance.
The company is a licensed and insured Texas electrical contractor under TECL 31876. It is also certified to install or work with equipment from Tesla, Enphase, REC, Sol-Ark and SPAN. Good Faith Energy operates mainly across Dallas–Fort Worth, Austin, Houston, San Antonio and surrounding communities.
Good Faith Energy is particularly strong in projects involving several connected technologies. A homeowner can combine rooftop panels with Tesla Powerwall storage, a smart electrical panel and a home EV charger. Its service department also handles maintenance and repairs, which can become important many years after the original installation.
Manufacturer warranties on panels commonly extend for 25 years, while the company provides its own workmanship protection. Customers should still request the complete warranty document because coverage periods can differ for panels, inverters, batteries, roof penetrations and labour.
Why Good Faith Energy is good for Texas homeowners: It provides a carefully integrated selection of solar, storage, electrical, roofing and EV-charging services. This can simplify technically complex installations that would otherwise require several contractors.

4. Longhorn Solar
Longhorn Solar has been installing solar energy systems in Texas since 2009. It serves residential and commercial customers in Greater Austin, San Antonio, Dallas–Fort Worth and Houston.
The company offers equipment from recognised manufacturers, including REC, Qcells and Mission Solar panels, along with SolarEdge, SMA and Tesla inverter technology. Battery choices can include Tesla Powerwall, FranklinWH and other home-storage systems.
Longhorn Solar publishes 25-year performance and workmanship warranties. It also provides system maintenance, solar-panel removal and reinstallation for roof replacement, hail-damage assistance and support for certain “orphaned” systems whose original installers are no longer available. These services are valuable in Texas, where major hailstorms and roof-insurance work can require panels to be temporarily removed.
The company lists Texas Electrical Contractor Licence TECL 27514 and maintains physical offices in Round Rock, San Antonio and Plano.
Why Longhorn Solar is good for Texas homeowners: Its long Texas operating history and post-installation services make it a practical company to investigate when future maintenance, roof work and local support are important parts of the decision.

5. Atma Energy
Atma Energy is a San Antonio-based solar and home-energy company with additional offices in Austin and Houston. It provides custom solar systems, battery storage, commercial installations, energy buyback plans and maintenance services.
Its approach goes beyond the original installation. Atma services and repairs solar systems installed by other companies, including systems whose original installers have closed or stopped providing support. The company also offers monitoring and preventative-maintenance services.
Atma publishes a 25-year production guarantee, 25-year workmanship warranty and 25-year leak-free warranty. Its systems can be combined with whole-home battery storage, while its solar-focused electricity plans are designed to help customers manage the value of power exported to the Texas grid.
Why Atma Energy is good for Texas homeowners: Its combination of solar installation, battery backup, electricity-plan support and repairs makes it useful for customers who want continued assistance after installation rather than a company focused mainly on selling new systems.

What Should Texas Homeowners Compare Before Choosing a Solar Company?
Request written proposals from at least three companies using the same expected system size and battery requirements. Each proposal should identify the panel, inverter and battery models, projected first-year production, annual degradation assumptions, cash price, financed price and total loan repayment.
Homeowners should verify the installer’s Texas electrical contractor licence. The Texas Department of Licensing and Regulation states that non-exempt electrical work must be completed by licensed individuals working through a licensed electrical contractor.
The warranty should clearly separate manufacturer protection from the installer’s workmanship coverage. Ask who will pay for labour, shipping, roof repairs and panel removal if equipment fails or the roof must be replaced.
Customers should also be careful with 2026 savings estimates. The IRS states that the Residential Clean Energy Credit applied to qualified home systems installed through December 31, 2025, and is unavailable for property placed in service after that date. A quotation for a system installed in 2026 should not assume that the former 30% residential federal credit remains available.
Frequently Asked Questions
Q: Is the 30% federal residential solar tax credit available in 2026?
A: No. According to the IRS, the Residential Clean Energy Credit is not available for residential clean-energy property placed in service after December 31, 2025. Customers should consult a qualified tax professional about their individual situation rather than relying only on a salesperson’s estimate.
Q: Will solar panels keep a Texas home running during an outage?
A: A normal grid-connected solar system usually shuts down during an outage to protect utility workers. Keeping the home powered normally requires compatible battery storage, an automatic transfer system and equipment capable of safely isolating the property from the grid.
Q: How long does a Texas solar installation take?
A: The physical installation may require only a few days, but the complete project can take several weeks. Roof inspections, engineering, permits, HOA approval, utility interconnection, final inspection and permission to operate can all affect the schedule.
Q: Should homeowners select the company offering the lowest price?
A: Not automatically. A cheaper proposal may use lower-output equipment, weaker workmanship protection, unrealistic production estimates or expensive financing hidden behind a low monthly payment. Compare the cash price, total financed cost, equipment specifications, warranties and expected utility savings before signing.
