How to Choose a Solar Installation Company in DFW

The best solar installation company for your DFW home is one that is licensed, insured and local enough to service your system for decades. It should give you an itemized quote, explain its warranties in writing and tell you the truth about 2026 incentives. That last test matters a lot this year: the 30% federal homeowner tax credit ended after 2025, and any company still promising it is a company to skip. This guide covers how to vet the business itself: who they are, how they sell and whether they will be around in year ten.

There are plenty of solar companies working in Dallas-Fort Worth. Some are excellent. Some are fine. And some are high-pressure sales operations that will sell you whatever you’ll sign for, whether or not it fits your home. Here is how to tell them apart.

7 Questions to Ask Every Solar Company

1. Where is your office, and who owns the company? A DFW-based installer has its reputation on the line in this market. You should be able to find a real local address and learn who runs the business.

2. Who will actually be on my roof? Many solar “installers” are sales companies that hire out the work to other crews. That is not always bad, but you should know who is doing the work, how they are trained and who supervises them.

3. Who holds the electrical license? In Texas, the electrical side of a solar job must be done under a licensed electrical contractor registered with the Texas Department of Licensing and Regulation (TDLR). Ask for the license number and look it up.

4. What certifications do your installers hold? NABCEP (North American Board of Certified Energy Practitioners) certification is a widely respected solar credential. Manufacturer certifications matter too. For example, battery makers like FranklinWH certify installers to install and register their systems for warranty.

5. What is your workmanship warranty, in writing? Panel and inverter makers cover their products. The installer should cover the installation itself, including roof penetrations, wiring and racking, under a separate written workmanship warranty. Ask how long it lasts and what it excludes.

6. Can I talk to customers whose systems are more than a year old? Anyone can find a happy customer from last week. A system that has made it through a Texas summer and a hail season tells you more.

7. What happens if I need service in year eight? Ask how service calls work, who answers and how quickly. This question separates installers from sales teams.

The 2026 Red Flag: Outdated Tax Credit Claims

This is the easiest test this year. The residential clean energy credit (IRC §25D) was ended early by the One Big Beautiful Bill Act, signed July 4, 2025. It no longer applies to systems completed after December 31, 2025. If a salesperson in late 2026 says you’ll “get 30% back” on a system you buy with cash or a loan, they are either uninformed or misleading you. Either way, that tells you something about the company.

Honest companies will tell you three things:

• Homeowner purchases completed in 2026 get no federal credit.
• Leases and PPAs may still carry commercial credits that the leasing company claims, and you should ask how much of that reaches your price.
• You should confirm tax questions with a tax professional, not a salesperson.

Other Red Flags in Solar Sales Pitches

“Free solar.” There is no free solar. The cost is built into a long loan, a lease or a power purchase agreement (PPA). These setups sometimes work for homeowners, but “free” is always misleading.

Pressure to sign today. A solar system will be on your roof for 25 years or more. “Today only” pricing is a sales tactic. If you do sign at your kitchen table, federal rules for sales made at your home generally give you three business days to cancel. Know that before anyone hands you a tablet.

Promises about your bill going to zero. Texas has no statewide net metering. In Oncor areas, what you earn for extra solar depends on your retail electric provider’s plan. Anyone promising a $0 bill without asking about your plan is guessing.

Vague equipment. “Premium tier-1 panels” means nothing without a brand and model number. Your contract should list exact models so equipment can’t be swapped after you sign.

Storm chasers. After big hail events, out-of-town crews flood DFW neighborhoods with solar and roofing offers. Some do fine work. But a company that leaves when the storms stop can’t honor a 10-year warranty.

Local vs. National Solar Companies

National companies offer scale, name recognition and sometimes lower prices. They may also mean call centers, distant decision-making and crews you never meet again.

Local installers offer direct accountability, faster service and real knowledge of DFW permitting, HOA rules and Oncor interconnection. They may cost a bit more and have tighter schedules in peak season.

The right fit depends on what you value. In our experience, the gap usually shows up after installation, when an inverter needs a firmware update, a squirrel chews a wire or an HOA asks a question. For more on this topic, see our guide on what to look for in a DFW solar power energy company.

Reading Online Reviews the Right Way

• Detail beats volume. Reviews that name people, timelines, equipment or how a service call was handled are more believable than “Great company!”
• Watch how they answer complaints. One calm, problem-solving reply to a bad review tells you more than dozens of five-star ratings.
• Check the pace. Steady reviews over years are a better sign than a sudden burst in a few weeks.
• Look for post-install stories. Reviews written months after install, about service or production, are the most useful.

Check Licenses, Insurance and Contracts

Before you sign, ask for and verify:

• The TDLR electrical contractor license number.
• Certificates of general liability and workers’ compensation insurance.
• A written contract listing equipment models, total price, payment schedule and warranties.
• Who handles permits, HOA paperwork and Oncor interconnection (it should be the installer).
• Whether the company can also handle a roof replacement or battery add-on, so one company is responsible if something goes wrong.

Frequently Asked Questions

How do I verify a solar company is licensed in Texas?

Ask for the electrical contractor license number and look it up on the Texas Department of Licensing and Regulation (TDLR) website. Also ask for current certificates of general liability and workers’ compensation insurance.

Is it a red flag if a solar company promises a 30% tax credit in 2026?

Yes. The federal residential solar credit ended for systems completed after December 31, 2025. A company still promising it to cash or loan buyers is either out of date or misleading you.

Should I choose a local or national solar installer in DFW?

National firms may offer lower prices, but local installers usually provide faster service and better knowledge of DFW permits, HOAs and Oncor interconnection. Both can do good work, so judge each on its warranty, references and service plan.

Can I cancel a solar contract signed at my home?

Federal rules for sales made at your home generally give you three business days to cancel. Read your contract’s cancellation terms before signing.
