Solar in Arlington: What Homeowners Should Know
Arlington sees an average of 5.5 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 12,848 kWh each year in Arlington — and paired with Texas's local electricity rate of $0.102/kWh, that's where the savings come from.
At those numbers, a Arlington homeowner saves about $109/month ($1,310/year). Against a $22,000 system cost (about $21,000 after Texas state incentives), that works out to a payback of about 16 years, after which the system produces essentially free power for two decades — an estimated $23,764 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Oncor, whose net metering policy directly affects how much credit you earn for surplus power.

Choosing a Solar Installer in Arlington
- 1.Get at least 3 quotes. Prices in Texas vary widely between installers — comparing bids on the same 8 kW system is the fastest way to avoid overpaying.
- 2.Confirm Oncor interconnection experience. An installer who regularly files with your local utility will move your permit and net-metering paperwork through faster.
- 3.Check licensing & the warranty. Look for NABCEP-certified installers and a workmanship warranty of 10+ years on top of the standard 25-year panel warranty.
- 4.Size for your actual usage. With 5.5 sun hours/day in Arlington, make sure the proposed system matches your kWh history — not just your roof space.
