How payback works
11.9 yrs
Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Lake Dallas
A typical solar installation here runs $13,900–$18,200. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Dallas–Fort Worth
Lake Dallas gets strong North Texas sun, so production per panel is high, but in deregulated Texas there's no statewide net metering, so your payback hinges on the solar buyback plan you choose. Some retail providers credit exports near the full retail rate; others pay far less, so the plan matters as much as the panels.
Peak sun hours
~5.3/day
Strong North Texas sun yields high annual production per installed kW.
Local electric rate
~15¢/kWh
The rate you offset; your export credit depends on the retail provider's buyback plan.
Annual output
~1,500 kWh/kW
A typical North Texas production factor per installed kW.
Incentives in 2026
The 30% federal residential solar credit (25D) expired December 31, 2025, so 2026 cash buyers get $0 federal credit. Texas has no state credit but exempts the added home value from property tax, and Oncor's 'Take a Load Off Texas' offers a solar-plus-battery rebate up to about $9,000 combined, though battery storage is required to qualify. Shop your retail provider's buyback plan before sizing a system.
Permits
Rooftop solar needs a building and electrical permit plus Oncor interconnection approval in Lake Dallas; a licensed installer handles the permitting and paperwork.
FAQ
Solar questions, answered for Lake Dallas
Is there still a federal solar tax credit in 2026?
No. The 30% residential solar credit (Section 25D) expired December 31, 2025. Cash buyers in 2026 receive $0 federal credit. Texas still exempts the added home value from property tax, Oncor offers a solar-plus-battery rebate, and leases/PPAs can use the business 48E credit through 2027.
What's the payback period on solar in Lake Dallas?
Use the estimator above: it divides your net system cost by estimated annual bill savings. DFW has great sun, but with no federal credit in 2026 and buyback rates that vary by provider, expect a longer payback than the often-quoted national figures, your retail plan matters most.
Does Texas have net metering?
Not statewide. In deregulated DFW, Oncor delivers the power but your retail electric provider sets the solar buyback rate, some credit exports near the full retail rate, others well below it. Confirm yours before you size a system.
Do I need a battery in Lake Dallas?
Not always, but it helps here: a battery is required to claim Oncor's rebate, adds backup power during outages, and lets you store midday production when buyback rates are low. It adds roughly half again to the project cost.
