Residential Energy Storage

Use solar energy, all day, all night.

SunSource is a Tesla Powerwall Certified Installer, which means we now offer a customized solar-plus-battery solution that enables you to access the free, abundant power of the sun and reduces your reliance on fossil fuels.

With Powerwall you can store solar energy generated during the day for use any time. During the day, the sun shines on your solar panels, charging your battery. At night, your home draws electricity from your battery, powering your home with clean, sustainable energy 24/7.

Installing Powerwall with SunSource is easy. We take care of everything including include system design, permitting, installation, and financing.

Powerwall offers many benefits, including:

  • Self-Powered – Powerwall increases the self-consumption of solar power generation. Powerwall can store surplus solar energy during daylight hours and use
    that energy later when the sun is not shining.
  • Time-Based Control – Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods
    when electricity demand is higher.
  • Back-up Power – Assures power in the event of a grid outage.
  • Long Battery Life – Warrantied for 10 years.

Simple Backup Power

Powerwall consists of a 14 kWh lithium-ion battery pack, liquid thermal control system, an integrated inverter and software that intelligently dispatches electricity when it’s needed most. The unit mounts seamlessly on a wall or on the ground, indoors or outdoors, and is connected to the grid to export excess energy, maximizing your opportunity for economic benefit.

Energy Independence

Modular Design

“I’ll do it myself!” Everyone has a little bit of an independent streak in them. Energy Storage allows you to take it to the next level! There’s nothing quite like the feeling you get when you know you’ll never have another utility bill showing up in the mailbox ever again! We can get your home set up to be self-sustaining. Just get in touch with us to find out how.


Want to do some now, and add later? Not a problem! Our systems are designed to be modular. If you need/want more storage in the future it’s easy and affordable to add on to your existing system.

The power companies often have Demand charges and Time Of Use charges that add $$$ to your power bills. Our energy storage systems can help avoid/offset some or all of those charges. Have us look at your power bills to see how you can start saving money today!
