Why Southlake solar owners are adding batteries right now
The conversation in Southlake has shifted from "if" the grid will fail to "when it fails next, what's our plan." The Oncor model rewards self-consumption: charge the battery during the day, run the house off it during peak. Each ERCOT cold-weatherization audit since Uri has flagged the same gas-supply weakness — meaning the next freeze can replay 2021. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Battery storage retrofitted onto Southlake solar usually delivers another 20-31% bill reduction by capturing midday surplus for evening use.
Solar in Southlake: common questions
What's the best ROI battery for a Southlake solar retrofit?
We size Southlake systems at 13.5-27 kWh based on critical-loads inventory: fridge, HVAC, well pump, internet and lights for 12-36 hours. Franklin aPower 2 (15 kWh) with Franklin aGate — newer entrant that's gaining traction in Southlake retrofits. Tesla Powerwall 3 — single-unit installation, sized for typical Southlake 3-bed home with 13.5 kWh capacity covering essentials for 12-24 hours. Both systems are eligible for the 30% Federal Investment Tax Credit through 2032.
What's the typical ROI on a battery retrofit for Southlake solar homes?
Yes, retrofits are the majority of our Southlake battery work and almost always go in clean. Whether your panels came from Sunnova, ADT Solar, SunPower, Tesla, Vivint or Freedom Forever, we can layer storage on top with Tesla, Enphase or Franklin. Our retrofit assessment covers your inverter, main panel and grounding; the typical Southlake home retrofits with no inverter swap. Southlake permits typically issue in 1-2 weeks and Oncor PTO follows in 2-3 weeks.
Will a battery actually save 20-31% on my Southlake energy bill?
If your Southlake home runs heavy AC during summer, the savings ramp up — peak-rate avoidance is where the dollars compound. Southlake customers report $40-90/month bill reduction after pairing storage with a TOU rate plan. Summer peaks in Texas hit 24-28¢/kWh during 4-7 PM; off-peak overnight rates drop to 4-6¢/kWh — exactly the spread a battery converts into savings. 0¢ buyback on Oncor Electric Delivery means every exported kWh is essentially free to the utility — battery storage flips that around.
The Math Behind the $31 Battery Cost
Many Southlake 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.

With the Light Battery Program™
Battery lease: $85/monthBattery credit: –$54/month
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 Southlake 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
- Pool equipment
- Appliances and entertainment systems
- EV charging
- Family activity
Why More Southlake 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
