Smart-E Battery

Battery storage paired with solar PV gives you a new way to control your home’s power supply and keep the lights on during an outage. Batteries make your home more resilient by allowing you to decide when and how your solar power is consumed.

Who can add a battery?
Batteries can be added to an existing solar PV system or coupled with a new solar PV installation.

Key terms:

  • 5, 7 and 10-year terms available
  • Finance battery storage up to $40,000

Whether you are looking to improve the comfort of your home, lower your energy costs, or increase your home’s value, a Smart-E Loan makes it easy!

Typically when your solar PV system produces more electricity than your home needs at that time (like when the sun is out but you’re at work), it gets sent back to the utility grid. Batteries allow you to store that extra electricity and use it to power your home later.

If there is a grid outage event, you can use your stored solar energy to power
certain loads in your home like your lights and refrigerator until the grid comes back online. Since your batteries are recharged by solar, your battery will
recharge itself each day when the sun comes out.

Cleaner: Unlike generators that run on fossil fuels, batteries charged by solar energy are a cleaner option for powering your home during an outage.

Customizable: Batteries can be customized to meet your home’s energy needs. Ask your contractor about designing a system that works for you.
