How storage protects Plano homes through the next ERCOT event
Living in Plano means living with the Oncor grid — and that grid has buckled twice in five years. The May 2024 derecho ripped through Plano with 100+ mph winds, downing transmission lines and leaving Oncor service interrupted for 36+ hours in some neighborhoods. The Oncor model rewards self-consumption: charge the battery during the day, run the house off it during peak. When Oncor crews are stretched thin, on-site storage is what keeps a Plano home livable. The 30% Federal Investment Tax Credit applies to standalone batteries through 2032 with no upper cap.
Solar in Plano Solar Battery Installation The Light: common questions
Tesla Powerwall, Enphase, or Franklin — which is right for Plano homes?
We size Plano systems at 13.5-27 kWh based on critical-loads inventory: fridge, HVAC, well pump, internet and lights for 12-36 hours. Enphase IQ Battery 5P (modular) — start at 5 kWh, expand to 25 kWh as Plano household demand grows. Enphase IQ Battery 10 plus IQ8H microinverters for sun-up backup — a fully Enphase-stack solution for Plano retrofits. Either choice claims the 30% federal credit; we walk you through the tradeoffs in your free assessment.
Do I need to replace my inverter to add a battery in Plano?
Yes — adding a battery to existing Plano solar is the standard scenario, not the exception. 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 assess your existing inverter and main panel first; older string inverters sometimes need a small AC-coupling component (~$1,200), but most Plano retrofits go in clean. Plano permits typically issue in 1-2 weeks and Oncor PTO follows in 2-3 weeks.
Will a battery cut my Plano electric bill?
On top of bill savings, the avoided costs from the next major event (Winter Storm Uri (Feb 2021)) often equal a year of savings in a single weekend. 0¢ buyback on Oncor Electric Delivery means every exported kWh is essentially free to the utility — battery storage flips that around. 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. Typical Plano savings come in at $40-90/month once a battery is paired with a TOU plan from Rhythm, Octopus or Reliant.
Why Solar Panels Alone Aren’t Eliminating Electric Bills
Many homeowners in Plano installed solar expecting their electric bill to drop close to zero.
But many still see $120–$200 monthly bills, even with a solar system producing plenty of energy.
The reason is simple:
Solar power is produced during the day, while homes often use the most electricity later in the evening.
In many Plano homes, energy demand increases when:
Why Many Solar Homes Still Rely on the Grid
Most solar systems operate in a simple cycle.
During the day:
- Solar panels produce electricity
- Extra solar energy is exported to the grid
- Solar production stops
- Electricity must be purchased from the grid
Exporting solar energy during the day
and then
buying electricity back later when prices are higher.
Even though the solar system produced plenty of energy overall.

How the Light Battery Program™ Changes the Math
Battery storage allows your solar system to store excess energy during the day.
That stored energy can then power your home after sunset, when electricity demand increases.
The Light Battery Program™ includes a $54 monthly battery credit that helps offset much of the battery cost.
Example scenario.
Typical Plano solar homeowner:
With the Light Battery Program™
Battery lease: $85/monthBattery credit: –$54/month
Instead of exporting solar power and buying electricity later, homeowners can use their solar energy when their home actually needs it.
A Battery Upgrade Designed for Existing Solar Systems
The Light Battery Program™ was built for homeowners who already have solar panels installed.
The program includes:
- Battery storage installation
- A participating electricity provider
- A fixed $54 monthly battery credit
- 1:1 net metering structure under the program
- Backup power capability
- Store more solar energy
- Reduce electricity purchased from the grid
- Add backup power protection

Before and After Adding Battery Storage
Before installing a battery:
Solar powers the home during the dayExtra solar energy exported to the gridElectricity purchased from the grid at night
Typical remaining bill:
~$150/month
After installing a battery:
Solar energy stored during the dayStored energy powers the home in the evening
Battery lease: $85/monthBattery credit: –$54/month
Effective cost:
~$31/month
Actual results depend on:
- Solar system size
- Household electricity usage
- Electric plan
- Battery capacity
Use the solar power your system already produces.

Frequently Asked Questions
The $54 monthly credit is available under the current participating retail plan used within The Light Battery Program™. Eligibility and plan terms are reviewed prior to enrollment.
Eligible homeowners enrolled in the participating retail plan receive 1:1 net metering under current plan terms. Details are confirmed before activation.
The Light Battery Program™ is primarily structured as a lease model to reduce upfront investment compared to traditional purchase financing.
Total bill impact depends on system size, usage patterns, and rate structure. Many homeowners reduce evening grid exposure significantly, but outcomes vary.
When configured for backup, the battery can power designated circuits or the home during grid interruptions and recharge from solar during daylight.
