Maximizing solar value in Garland with battery storage
Power in Garland runs through GP&L — a utility that has not modernized at the pace residents need. Garland Power & Light operates as a municipal utility — rates are competitive but ERCOT exposure remains. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Hurricane Laura in 2020 forced parallel evacuations across East Texas; Garland relatives took in displaced families with no power. On a typical Garland home with 7-10 kW of solar, a 13.5 kWh battery cuts the bill another 20-31% on top of solar-alone savings.
Solar in Garland: common questions
Which battery system maximizes self-consumption for Garland solar owners?
We size Garland systems at 13.5-27 kWh based on critical-loads inventory: fridge, HVAC, well pump, internet and lights for 12-36 hours. Two Powerwall 3 units totaling 27 kWh — for Garland homes with all-electric appliances or EV charging. FranklinWH aPower configured for partial-home backup — cost-optimized for Garland homes prioritizing essentials. Both options carry the 30% federal credit; the right pick comes down to your existing equipment.
How fast does a Garland battery retrofit pay for itself?
Most Garland battery installations are retrofits, and yes, they integrate with existing solar gear. 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 start with an inverter and panel inspection; the vast majority of Garland retrofits clear without swapping equipment. Garland permitting averages 1-2 weeks; GP&L PTO usually clears within 2-3 weeks after install.
How does adding a battery in Garland change my ROI on solar?
Garland customers report $40-90/month bill reduction after pairing storage with a TOU rate plan. Once you factor in the 30% federal credit and an avoided $600 per outage event, payback typically lands in the 6-10-year range. Texas TOU plans charge 24-28¢/kWh at peak and 4-6¢/kWh overnight; the battery moves load from the expensive window to the cheap window. Garland Power & Light pays around 4¢/kWh for solar exports — workable, but a battery still earns more by self-consuming kWh at retail rates.
The Math Behind the $31 Battery Cost
Many Garland 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™

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 Garland 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 Garland 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
