Maximizing solar value in Carrollton with battery storage
When Winter Storm Uri (Feb 2021) hit Carrollton, the homes that kept the lights on were the ones that already had batteries installed. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Carrollton sits within the path that Hurricane Beryl carved through Harris County in July 2024, forever changing the storage conversation. On Oncor territory, exporting solar is essentially a donation; storage flips that around. Most Carrollton solar owners see a 20-31% additional bill cut once the battery starts shifting peak-hour usage off-grid.
Solar in Carrollton: common questions
Powerwall vs Enphase vs Franklin — best value for Carrollton retrofit?
Sizing for Carrollton is usually 13.5-27 kWh, calibrated to keep essentials live through 12-36 hours of grid downtime. Enphase IQ Battery 5P stacked to 20 kWh — typical sizing for a Carrollton home with 4-bedroom HVAC and electric water heating. Enphase IQ Battery 10 plus IQ8H microinverters for sun-up backup — a fully Enphase-stack solution for Carrollton retrofits. Both options carry the 30% federal credit; the right pick comes down to your existing equipment.
Is a battery retrofit profitable for solar already on a Carrollton roof?
Yes — most Carrollton battery installations we do are retrofits, not bundled with new solar. We retrofit Tesla, Enphase and Franklin systems onto solar arrays from Sunnova, SunPower, ADT Solar, Vivint, Tesla Energy and other major installers. Our retrofit assessment covers your inverter, main panel and grounding; the typical Carrollton home retrofits with no inverter swap. Local permits in Carrollton take 1-2 weeks; Oncor PTO clears in 2-3 weeks post-install.
Will a battery actually save 20-31% on my Carrollton energy bill?
Oncor Electric Delivery pays 0¢/kWh for excess solar export, which makes self-consumption with a battery the highest-ROI play. Typical Carrollton savings come in at $40-90/month once a battery is paired with a TOU plan from Rhythm, Octopus or Reliant. Don't forget the federal ITC at 30% through 2032 — a Carrollton typical 13.5 kWh build sees roughly $4-6K back at tax filing. DFW REPs charge 24-28¢/kWh from 4-7 PM during summer peak while off-peak overnight rates drop to 4-6¢/kWh on plans like Rhythm Free Nights or Octopus Intelligent.
The Math Behind the $31 Battery Cost
Many Carrollton homeowners installed solar expecting their electric bill to disappear.
But today many still pay $120, $150, or even $200+ per month because most homes use the most energy after the sun goes down.
The Light Battery Program™ changes how solar works by adding battery storage and pairing it with an electricity plan that includes a $54 monthly battery credit.
Here’s a simplified example.

Instead of exporting solar cheaply during the day and buying power back at night, the battery allows you to store solar energy and use it when your home actually needs it.
Why Many Solar Homes in Carrollton Still Have Electric Bills
Across Texas, the original solar math has changed.
Several things happened:
- Solar buyback rates dropped
- Utilities increased delivery charges
- Evening electricity usage increased
- Homes consume the most energy after sunset
- Air conditioning
- Appliances and cooking
- Electronics and entertainment
- Laundry and household activity
- EV charging
Why More Carrollton Homeowners Are Adding Batteries
A battery changes how your solar system works.
Instead of exporting extra solar energy during the day, the battery stores it.
This allows homeowners to:
Use solar power at night
Stored solar energy powers the home after sunset when energy use is highest.
Reduce expensive evening energy imports
Electricity pulled from the grid during peak hours is often the most expensive.
Add backup protection
Without a battery, solar shuts off during power outages.
With a battery, your home can stay powered.
A New Way to Upgrade Your Solar System
The Light Battery Program™ was designed specifically for homeowners who already have solar but still pay a monthly electric bill.
The program combines:
- Battery storage
- A participating electricity provider
- A $54 monthly battery credit
- 1:1 net metering under current plan structure
- Backup capability during outages
Before and After Adding a Battery
Before battery installation:
Solar offsets daytime energyEvening energy is pulled from the grid
After adding a battery:
Daytime solar stored in batteryEvening energy powered by stored solar
Battery lease: $85/monthBattery credit: –$54/month
Actual results vary based on home size, energy usage, and solar production.
But the goal is simple:
Use your solar power when it’s most valuable.
