The Allen bill-cut math behind solar + storage
After what Winter Storm Uri (Feb 2021) did to Allen, homeowner sentiment toward the grid is permanently changed. Hurricane Harvey in 2017 dropped 50+ inches of rain on Allen and surrounding Collin County — flooding alone took transformers offline for weeks. Oncor pays nothing — zero cents — for excess solar pushed back to the grid, which means every kWh you don't store is a kWh you give away. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap. Battery storage retrofitted onto Allen solar usually delivers another 20-31% bill reduction by capturing midday surplus for evening use.
Solar in Allen: common questions
What's the best ROI battery for a Allen solar retrofit?
Typical Allen sizing lands at 13.5-27 kWh of usable storage, covering essentials for 12-36 hours unaided. Tesla Powerwall 3 — popular for Allen retrofits because it integrates AC-coupled with most existing inverter brands. Tesla Powerwall 3 paired with stackable Powerwall 2 — for Allen homes that need 27+ kWh of capacity. Both systems are eligible for the 30% Federal Investment Tax Credit through 2032.
Can I add storage without replacing my existing Allen solar inverter?
Yes, retrofits are the majority of our Allen battery work and almost always go in clean. 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. Our retrofit assessment covers your inverter, main panel and grounding; the typical Allen home retrofits with no inverter swap. Local permits in Allen take 1-2 weeks; Oncor PTO clears in 2-3 weeks post-install.
Will a battery actually save 20-31% on my Allen energy bill?
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. Because Oncor Electric Delivery doesn't pay residential solar exports (0¢ buyback), a battery is the smartest place for every kWh — store and self-consume rather than give away. The bigger you size the battery, the more peak hours you can dodge — Allen customers with EVs often go to 27 kWh for that reason. Battery owners in Allen typically see $40-90/month off the electric bill once they switch to a TOU plan from Rhythm Energy, Octopus or another REP.
The Math Behind the $31 Battery Cost
Many Allen 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 Allen 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 Allen 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 program combines:
- Battery storage
