How Georgetown homeowners use storage to reduce energy costs
Across Williamson County, residents who lived through Winter Storm Uri (Feb 2021) are upgrading their homes with on-site storage. PEC members in Georgetown use batteries to bridge the gap between solar overproduction at noon and household demand at sundown. Sub-zero temperatures during Uri locked Georgetown water mains in ice — homes without power couldn't run dripping faucets, and pipes burst by the thousands. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Battery storage retrofitted onto Georgetown solar usually delivers another 20-31% bill reduction by capturing midday surplus for evening use.
Solar in Georgetown: common questions
What battery captures the most kWh from a typical Georgetown solar array?
For most Georgetown homes the right capacity is 13.5-27 kWh — enough to run essentials (refrigerator, HVAC, internet, lights, well or sump pump) for 12-36 hours. Tesla Powerwall 3 — popular for Georgetown retrofits because it integrates AC-coupled with most existing inverter brands. Powerwall 3 with the Tesla Backup Gateway 2 — full-home backup, plus Storm Watch automatic pre-storm charging in Georgetown. Both options carry the 30% federal credit; the right pick comes down to your existing equipment.
How does adding a battery to existing Georgetown solar lower my electric bill?
Yes — most Georgetown battery installations we do are retrofits, not bundled with new solar. 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. We assess your existing inverter and main panel first; older string inverters sometimes need a small AC-coupling component (~$1,200), but most Georgetown retrofits go in clean. Permitting in Georgetown is generally 7-14 days, and PEC PTO follows in 14-21 days.
How does adding a battery in Georgetown change my ROI on solar?
Most Georgetown households save $40-90/month by combining battery storage with a time-of-use plan from a TX REP like Rhythm Energy or Octopus. Pedernales Electric Cooperative offers a 7¢/kWh export credit — better than most TX utilities, but a battery still wins for backup power and time-of-use shifting. Once you factor in the 30% federal credit and an avoided $350 per outage event, payback typically lands in the 5-8-year range. Texas peak rates run 21-28¢/kWh in 4-7 PM windows; off-peak nights drop to 4-6¢/kWh — that delta is what a battery captures.
The Math Behind the $31 Battery Cost
Many Georgetown 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 Georgetown 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 Georgetown 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.
