Battery storage in Arlington — the resilient-home story
Every Arlington homeowner who lost power during the last major event understands why batteries are now standard equipment. On Oncor territory, exporting solar is essentially a donation; storage flips that around. Sub-zero temperatures during Uri locked Arlington water mains in ice — homes without power couldn't run dripping faucets, and pipes burst by the thousands. Oncor restoration takes time during major events; a battery turns 12-36 hours of darkness into normal living. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap.
Solar in Arlington Solar Battery Installation The Light: common questions
What's the most-installed battery system in Arlington right now?
Most Arlington households install 13.5-20 kWh — enough to run the fridge, AC, lights and internet through a one- or two-day event. Enphase IQ Battery 5P (modular) — start at 5 kWh, expand to 25 kWh as Arlington household demand grows. Tesla Powerwall 3 paired with stackable Powerwall 2 — for Arlington homes that need 27+ kWh of capacity. Either choice claims the 30% federal credit; we walk you through the tradeoffs in your free assessment.
What's involved in adding battery storage to Arlington solar systems?
Yes — most Arlington battery installations we do are retrofits, not bundled with new solar. We commonly add Powerwall 3, IQ Battery 5P/10, and Franklin aPower onto third-party solar from Sunnova, ADT, SunPower, Freedom Forever and others. Our retrofit assessment covers your inverter, main panel and grounding; the typical Arlington home retrofits with no inverter swap. Permitting in Arlington is generally 7-14 days, and Oncor PTO follows in 14-21 days.
Are batteries worth it financially for Arlington homeowners?
Arlington homeowners typically save $40-90/month with a battery on a time-of-use plan from REPs like Rhythm Energy, Octopus Energy or Constellation. 0¢ buyback on Oncor Electric Delivery means every exported kWh is essentially free to the utility — battery storage flips that around. The math sharpens further if Arlington REPs raise time-of-use peaks again next summer — every additional cent of peak rate widens the gap. Peak rates in Arlington run 21-28¢/kWh during the 4-7 PM window; off-peak nights drop to 4-6¢/kWh on plans like Rhythm Free Nights or Octopus Intelligent.
Electricity Use Peaks After the Sun Goes Down
Many homeowners in Arlington installed solar expecting their electric bills to drop dramatically.
But many solar homeowners still see $120–$200 monthly electricity bills.
The reason is simple:
Solar panels generate most of their electricity during the middle of the day, but homes often use the most electricity in the evening.
In many Arlington homes, electricity usage increases when:
The Export vs. Import Problem
Most solar systems operate the same way.
During the day:
- Solar panels generate electricity
- Extra energy is exported to the grid
- Solar production stops
- Electricity is purchased from the grid
Selling solar power cheaply during the day
and
buying electricity back later at full price.
Even though their solar system produced enough energy overall.

How the Light Battery Program™ Changes the Math
Battery storage allows your solar system to store excess energy during the day.
Instead of exporting that power to the grid, the battery saves it.
That stored energy can then power your home during the evening when electricity demand is highest.
The Light Battery Program™ includes a fixed $54 monthly battery credit, which helps offset the cost of the battery.
Example scenario.
Typical Arlington solar homeowner:
With the Light Battery Program™
Battery lease: $85/monthBattery credit: –$54/month
Instead of exporting solar energy and buying electricity later, homeowners can store their solar power and use it when their home actually needs it.
A Battery Upgrade Designed for Existing Solar Systems
The Light Battery Program™ was designed specifically for homeowners who already have solar installed.
The program includes:
- Battery storage installation
- A participating electricity provider
- A fixed $54 monthly battery credit
- 1:1 net metering structure under the program
- Backup power capability during outages
- Store more of their solar energy
- Reduce electricity purchased from the grid
- Add backup power protection

Before and After Adding Battery Storage
Before installing a battery:
Solar powers the home during the dayExtra energy exported to the gridElectricity purchased from the grid at night
Typical remaining bill:
~$150/month
After installing a battery:
Solar energy stored during the dayStored energy powers the home in the evening
Battery lease: $85/monthBattery credit: –$54/month
Effective cost:
~$31/month
Actual results depend on:
- Solar system size
- Household electricity usage
- Electric plan
- Battery capacity
Use the solar power your system already produces.

Eligible homeowners enrolled in the participating retail plan receive 1:1 net metering under current plan terms. Details are confirmed before activation.
The Light Battery Program™ is primarily structured as a lease model to reduce upfront investment compared to traditional purchase financing.
Total bill impact depends on system size, usage patterns, and rate structure. Many homeowners reduce evening grid exposure significantly, but outcomes vary.
When configured for backup, the battery can power designated circuits or the home during grid interruptions and recharge from solar during daylight.
