Solar batteries
Use your solar
after the sun goes down.
A battery stores the power your panels make during the day, so the house can run on it at night instead of buying it from the grid.
We install Sigenergy batteries, sized to how much power you use at night. You get a written price before we start.
Three ways to do it
New solar and a battery,
or a battery on its own.
A battery for the solar you have
Already got panels? We check your inverter first, then add a battery that works with it.

Sigenergy battery modules stack, so you can add more storage later if your use goes up.
Battery experience
We commission large battery
storage systems too.
Most of our work is home batteries. We also commission large battery storage systems, so batteries are work we know well.

the house on your solar.

Teresa had solar and a battery put in, and her older house rewired. She thanked Jason and the boys for professional, efficient work.

Questions
Battery questions,
plain answers.
How big a battery do I need?
It depends on how much power you use at night. Send us a couple of recent bills and we'll size it and give you a written price.
Can you add a battery to my existing solar?
Usually, yes. We check your inverter and switchboard first, then tell you what will work and what it costs.
Do I need solar to get a battery?
Most people pair a battery with solar, because that's where the savings come from. We'll tell you whether a battery makes sense for your house.
Will it keep the power on in a blackout?
It can, if the system is set up for backup. Tell us which circuits matter most and we'll quote it that way.
Where does the battery go?
Usually on an outside wall or in the garage, out of direct sun. We pick the spot with you.
What brand do you install?
We install Sigenergy batteries.
