DFW is the largest metro in Texas and sits in the middle of Hail Alley. The company you choose determines whether your system survives 25 years of North Texas weather — and whether you actually save money without the federal tax credit.
The best solar company in DFW in 2026 should have: TDLR electrical contractor license, hail-rated panels with enhanced testing, 50+ Oncor interconnections, ERCOT/REP buyback expertise, transparent pricing at $2.30-$2.70/W, coverage across all DFW suburbs, and a 25-year workmanship warranty. Get at least 3 quotes and compare line-item pricing.
The 30% residential solar ITC (Section 25D) expired December 31, 2025. Cash and loan buyers get $0 from the IRS. Every dollar of installer overcharge comes directly out of your pocket.
DFW averages 7-10 hail events per year. A cheap installation with non-hail-rated panels is not a savings — it is a $25,000 liability waiting to be destroyed.
DFW is deregulated. Your REP, not Oncor, determines your buyback rate. Choosing the wrong REP plan can cut your solar savings by 40%. Your installer must understand this.
The difference between a $2.40/W installer and a $3.50/W installer on a 10 kW system is $11,000
Without the federal ITC, that is 100% out-of-pocket — no 30% cushion to absorb the mistake.
Evaluate every installer against these seven criteria. Ask the specific questions listed under each one. The answers will tell you everything you need to know.
The legal requirement most buyers never verify
Ask the installer:
“What is your TDLR electrical contractor license number?”
DFW averages 7-10 hail events per year — this is non-negotiable
Ask the installer:
“What hail rating do your panels carry? Does the warranty cover hail-related damage?”
Oncor interconnection takes 4-8 weeks if done right, months if done wrong
Ask the installer:
“How many Oncor interconnections have you completed? Will you handle the rebate application?”
Your Retail Electric Provider determines your export value
Ask the installer:
“Which REP plans work best with solar in DFW? What buyback rate did you assume in my savings estimate?”
Line-item quotes, not mystery bundle pricing
Ask the installer:
“Can I see a line-item cost breakdown? What is the all-in per-watt price?”
DFW sprawls 9,300+ square miles — will they service your suburb?
Ask the installer:
“Do you serve my specific address? Are your crews your own employees?”
The warranty that separates serious installers from fly-by-night companies
Ask the installer:
“What is your workmanship warranty length? What happens if there's a roof leak in year 12?”
DFW is a top-10 solar market, which means it attracts legitimate companies and predatory ones in equal measure. Watch for these warning signs.
The Section 25D residential solar ITC expired December 31, 2025. If an installer quotes you a 30% credit on a cash or loan purchase in 2026, they are either uninformed or deliberately misleading you.
A solar installer without a TDLR electrical contractor license is operating illegally in Texas. Do not allow unlicensed work on your roof or electrical panel.
High-pressure closing tactics. A legitimate installer will hold a quote for 30 days or more. Solar panels are not going anywhere overnight.
Standard IEC testing is the minimum. In DFW's severe hail zone, you need enhanced hail testing documentation and a workmanship warranty that covers hail-related installation damage.
Your solar savings depend on your REP's buyback rate. If the installer quotes savings based on a plan you are not on, the numbers are fiction.
If the company selling you solar is not the company installing it, accountability is split. Ask directly: "Are your installation crews W-2 employees?"
Oncor interconnection is the final step before your system goes live. If the sales rep cannot explain the timeline and documentation, they likely have limited Texas experience.
Follow these steps to find the best value for your DFW home.
Contact 3+ installers who serve your specific DFW suburb. Mix local companies and regional installers. Avoid companies that only sell over the phone and never visit your roof.
Do not compare totals alone. Break down $/W pricing, equipment brands, Oncor interconnection fees, and permits. Fair DFW range: $2.30-$2.70/W for Tier-1 equipment.
Check each installer's TDLR license at tdlr.texas.gov. Ask for panel hail test documentation. Both are non-negotiable in DFW.
Have each installer analyze your actual REP plan for solar buyback value. If they assume a generic rate instead of checking your plan, the savings estimate is unreliable.
Ask each installer the 7 questions from this guide. Their answers — or inability to answer — will immediately separate the experts from the salespeople.
The cheapest quote with no hail warranty and 5-year workmanship coverage is not a value — it is a risk. Choose the best combination of equipment, warranty, Oncor experience, and fair pricing.

Common questions about choosing a solar company in DFW.
The best solar company in DFW should have a valid TDLR electrical contractor license, NABCEP certification, enhanced hail-rated panels, 50+ Oncor interconnections completed, transparent per-watt pricing between $2.30-$2.70/W, a 25-year workmanship warranty, and their own installation crews serving all DFW suburbs. NuWatt Energy meets all seven criteria with coverage across Dallas, Fort Worth, Plano, Frisco, McKinney, Allen, Arlington, and beyond.
Fair DFW solar pricing in 2026 ranges from $2.30 to $2.70 per watt for quality Tier-1 panels (Silfab, REC, Hyundai) with Enphase microinverters. A typical 10 kW system costs $23,000-$27,000 installed. The federal Section 25D residential tax credit expired December 31, 2025 — there is no 30% credit for cash or loan purchases.
Oncor administers the Take a Load Off Texas program, which offers rebates ranging from $300 to $3,500 for qualifying solar and battery systems. The program requires a smart thermostat installation. Your installer should handle the rebate application as part of the project. Availability depends on annual program funding.
Yes, but the math is tighter. DFW gets 5.2 peak sun hours per day and has some of the lowest installation costs in the country at $2.30-$2.70/W. With the right REP buyback plan and Oncor rebate, payback is typically 8-11 years. Through Propel Solar financing, a third-party system owner can claim the Section 48/48E commercial ITC for projects beginning construction before July 4, 2026, reducing your fixed monthly payment below your current electric bill.
DFW buyback rates vary by REP from 3 cents to 8.5 cents per kWh. Some REPs offer 1:1 net metering (your export rate equals your consumption rate) while others offer avoided-cost buyback at wholesale rates. Ask your installer to model savings using your actual REP plan, not a generic assumption. Switching REPs to optimize solar buyback is common and free in the deregulated ERCOT market.
Quality panels with IEC 61215 certification can withstand 1-inch hailstones at 51 mph. Premium panels like Silfab and REC carry enhanced hail testing beyond the IEC standard. DFW hail can exceed 2 inches in severe storms, so enhanced hail certification and a workmanship warranty that covers hail-related installation damage are essential. Proper mounting angle and racking also affect hail resilience.
A typical DFW solar installation takes 1-2 days of roof work. However, the full timeline from contract to system activation (Permission to Operate) is 6-12 weeks: 1-2 weeks for design and permitting, 1-2 days for installation, 2-4 weeks for city inspection, and 4-8 weeks for Oncor interconnection. Experienced installers with strong Oncor relationships consistently hit the shorter end of this timeline.
Yes. Plano, Frisco, and McKinney are all in the Oncor territory with the same interconnection process and rebate availability as Dallas proper. These suburbs have excellent solar potential with 5.2 peak sun hours, large roof areas on newer homes, and relatively fast city permitting. The same 7 criteria in this guide apply regardless of which DFW suburb you are in.
No outdated tax credit promises. No high-pressure sales. Just honest 2026 numbers, 3 panel tier options, hail-rated equipment, and a line-item quote you can compare against anyone.
