Battery storage and the Helotes solar bill cut
Across Bexar County, residents who lived through Winter Storm Uri (Feb 2021) are upgrading their homes with on-site storage. CPS service held up better than ERCOT IOUs during Uri, but stored backup is still the safest bet for Helotes homes. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Heat advisories blanketed Helotes for the entire August 2023 calendar month, with overnight lows that never dropped below 80°F. Battery storage retrofitted onto Helotes solar usually delivers another 20-31% bill reduction by capturing midday surplus for evening use.
Solar in Helotes: common questions
Which battery cuts Helotes bills the most when added to existing solar?
Typical Helotes sizing lands at 13.5-27 kWh of usable storage, covering essentials for 12-36 hours unaided. Enphase IQ Battery 10 — three IQ Battery 5P units stacked to 15 kWh, ideal for Helotes homes already running Enphase microinverters. FranklinWH aPower + aGate combo — competitive on cost-per-kWh for Helotes customers comparing systems. 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 Helotes roof?
Yes, retrofits are the majority of our Helotes battery work and almost always go in clean. We retrofit Tesla, Enphase and Franklin systems onto solar arrays from Sunnova, SunPower, ADT Solar, Vivint, Tesla Energy and other major installers. We assess your existing inverter and main panel first; older string inverters sometimes need a small AC-coupling component (~$1,200), but most Helotes retrofits go in clean. Local permits in Helotes take 1-2 weeks; CPS PTO clears in 2-3 weeks post-install.
How much can a battery cut my Helotes bill if I already have solar?
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. Helotes customers report $40-90/month bill reduction after pairing storage with a TOU rate plan. Factor the 30% federal tax credit, $750 avoided per outage, and 6-9-year payback — the math holds in most Helotes ZIPs. CPS Energy 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 Helotes 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 Helotes 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
- Cooking
- Pool systems
- EV charging
Why More Helotes 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

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:
