San Antonio Solar Battery Installation The Light Battery Program™
Add a battery, receive a $54 monthly credit, and store your solar energy for nighttime use.
Electricity Costs Are Rising Across San Antonio
Many homeowners in San Antonio installed solar panels expecting their electricity bills to drop dramatically.
But many still see $120–$200 monthly electric bills, even with solar systems producing plenty of energy.
The reason comes down to how electricity is used throughout the day.
Solar panels generate most of their electricity during:
- Late morning
- Midday
- Early afternoon
But homes in San Antonio often use the most energy during the evening, when:
- Air conditioning continues running
- Families return home
- Appliances and electronics are used
Why Solar Energy Is Often Sold to 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
buying electricity back later in the evening.
Even though the solar system produced enough energy overall.

How the Light Battery Program™ Changes the Math
A solar battery allows your system to store excess solar energy during the day.
That stored energy can then power your home after sunset, when electricity demand is highest.
The Light Battery Program™ includes a $54 monthly battery credit that helps offset the cost of the battery.
Example scenario.
Typical San Antonio solar homeowner:
- Remaining electric bill:
- $150/month
With the Light Battery Program™
Battery lease: $85/monthBattery credit: –$54/month
Effective battery cost: about $31/month
Instead of exporting solar power and buying electricity later, homeowners can store their solar energy and use it when their home needs it most.

CPS Energy provides stability.
But timing still matters.
Summer cooling demand continues to rise.
If your solar system was built only to offset usage — not manage timing — it may be under-optimized.
The Light Battery Program™ was designed to modernize that structure.
