Battery backup
Keep the lights on when Texas doesn’t
A home battery stores the power your solar panels make, so your home keeps running through outages and you use more of your own clean energy. We add batteries to new systems and to solar you already have.
Why add a battery
Your solar, working around the clock
Ride out outages
Texas storms and grid emergencies happen. A battery switches on automatically so the essentials keep running.
Use your own solar at coal
Store the power your panels make in the afternoon and use it after sunset instead of buying it back.
Dodge peak prices
On time-of-use plans, run your home from the battery when grid power costs the most.
Peace of mind
Keep medical devices, the fridge, Wi-Fi and A/C going while the street goes dark.
How it works
Backup built around your home
Already have panels from another installer? We can add a battery to most existing systems too.
- 1
Pick what matters
Whole home, or just the essentials? We help you decide which circuits to back up.
- 2
Size it right
We size the battery to your usage and your solar, so you don’t pay for capacity you won’t use.
- 3
Install & connect
We install it with your new or existing solar system and set up the app so you can watch it work.
How do I pay for it?
Three ways: zero down with payments deferred 12 months, a solar loan, or cash (including a mortgage refinance). We’ll compare them side by side for you.
What happens in a power outage?
A standard grid-tied system shuts off during an outage for line-worker safety. Add a battery and your home keeps running on stored solar power.
