Katy Solar Battery Installation The Light Battery Program™
Add a battery, receive a $54 monthly credit, and store your solar power for night-time use.
Electricity Demand in Katy Peaks After Sunset
Many homeowners in Katy installed solar expecting their electric bill to drop close to zero.
But many still see $120–$250 electric bills every month.
The reason comes down to when energy is used.
Solar panels generate most of their electricity during:
- Late morning
- Midday
- Early afternoon
But homes in Katy often use the most energy during:
- Evening hours
- Nighttime cooling
- After families return home
Why Solar Energy Leaves the Home Too Early
Without a battery, most solar systems operate in a simple way.
During the day:
- Solar panels generate electricity
- Extra energy is exported to the grid
- Solar production stops
- The home buys electricity back from the grid
- Selling solar energy cheaply during the day
and
Buying electricity later at full price.
That’s why even large solar systems can still leave homeowners with $150+ monthly electric bills.

How the Light Battery Program™ Changes the Math
Battery storage allows your solar system to save energy for later.
Instead of exporting excess solar power during the day, the battery stores it.
That stored energy can then power your home in the evening when electricity demand is highest.
The Light Battery Program™ includes a $54 monthly battery credit, which helps offset the battery cost.
Example scenario.
Typical Katy 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
This allows homeowners to store their solar power and use it later, instead of buying electricity from the grid.
