Cypress Battery Storage — Self-Consume Solar, Save More

Why Cypress solar owners are adding batteries right now
Battery storage in Cypress stopped being a luxury the moment the Hurricane Beryl (July 2024) happened. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. On CenterPoint Energy lines, residential solar export pays nothing — a battery turns those exports into evening usage. Winter Storm Heather in early 2024 brought another freeze event to Cypress, and ERCOT once again came within margin of load-shed. Most Cypress solar owners see a 20-31% additional bill cut once the battery starts shifting peak-hour usage off-grid.
Solar in Cypress: common questions
Powerwall vs Enphase vs Franklin — best value for Cypress retrofit?
Most Cypress households install 13.5-20 kWh — enough to run the fridge, AC, lights and internet through a one- or two-day event. Enphase IQ Battery 10 plus IQ8H microinverters for sun-up backup — a fully Enphase-stack solution for Cypress retrofits. Franklin aPower 2 with 13-year warranty — long-tail value for Cypress homeowners staying long-term. Both qualify for the 30% federal tax credit on the full installed cost.
How does adding a battery to existing Cypress solar lower my electric bill?
Yes, retrofits are the majority of our Cypress battery work and almost always go in clean. We commonly add Powerwall 3, IQ Battery 5P/10, and Franklin aPower onto third-party solar from Sunnova, ADT, SunPower, Freedom Forever and others. We start with an inverter and panel inspection; the vast majority of Cypress retrofits clear without swapping equipment. Cypress permits typically issue in 1-2 weeks and CenterPoint PTO follows in 2-3 weeks.
Is the 31% bill reduction realistic for typical Cypress homes?
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. Cypress customers report $40-90/month bill reduction after pairing storage with a TOU rate plan. 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 Cypress customers usually justify the spend within the first 4-7 winters.
The Math Behind the $31 Battery Cost
Many Cypress 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 Cypress 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 Cypress 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.
