Spring, TX Battery Installation — Turn Solar Surplus Into Savings
Trusted Partners
The Spring bill-cut math behind solar + storage
After what Hurricane Beryl (July 2024) did to Spring, homeowner sentiment toward the grid is permanently changed. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. CenterPoint customers in Spring watched roughly 2.7 million homes lose power during Hurricane Beryl in July 2024 — battery storage is the post-Beryl insurance policy. The summer 2023 heat dome forced ERCOT into multiple Energy Emergency Alerts as Spring demand pushed grid capacity past safe margins. Adding a battery to existing Spring solar typically cuts the energy bill an additional 20-31% by self-consuming peak kWh that would otherwise export at low buyback rates.
Solar in Spring: common questions
Tesla Powerwall vs Enphase IQ — which saves more in Spring?
Typical Spring sizing lands at 13.5-27 kWh of usable storage, covering essentials for 12-36 hours unaided. Franklin aPower 2 with 13-year warranty — long-tail value for Spring homeowners staying long-term. FranklinWH aPower + aGate combo — competitive on cost-per-kWh for Spring customers comparing systems. Both qualify for the 30% federal tax credit on the full installed cost.
How fast does a Spring battery retrofit pay for itself?
Yes — most Spring battery installations we do are retrofits, not bundled with new solar. We can add Tesla Powerwall, Enphase IQ Battery, or Franklin aPower to systems originally installed by Sunnova, ADT Solar, SunPower, Freedom Forever, Vivint and others. Step one is checking your inverter and main panel — most Spring retrofits go in without changes; older string inverters occasionally need a small AC-coupling adder (~$1,200). Permitting in Spring is generally 7-14 days, and CenterPoint PTO follows in 14-21 days.
Will a battery actually save 20-31% on my Spring energy bill?
Battery owners in Spring typically see $40-90/month off the electric bill once they switch to a TOU plan from Rhythm Energy, Octopus or another REP. 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. 0¢ buyback on CenterPoint Energy means every exported kWh is essentially free to the utility — battery storage flips that around. Plug in time-of-use exposure plus the 30% credit and Spring customers usually justify the spend within the first 4-7 winters.
The Math Behind the $31 Battery Cost
Many Spring 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 Spring 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 systems
- Appliances and cooking
- Electronics and entertainment
- EV charging
Why More Spring 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.
