Tesla Powerwall Battery Installation


Strengthen your solar array with a solar battery backup for your home

We’re proud to be one of the few companies in our region to offer the Tesla Powerwall battery system installations to complement a solar panel installation or add to an existing solar array. With a specially-designed solar battery, you can store energy throughout the day, saving it for peak demand and nighttime energy usage.

Tesla Powerwall

The Tesla Powerwall is one of the most advanced residential energy storage systems in the world. The Powerwall utilizes its DC energy storage system at a usable capacity of 13.5 kilowatt-hours per Powerwall.

To access more storage capacity, multiple Powerwalls may be installed in a parallel fashion. Internally, inverters have been installed atop the battery allowing the power to toggle between AC and DC stored power, allowing it to support large power draws.

Tesla Powerwall App

When you install a residential solar battery as part of your solar panel system, you’re able to store excess solar electricity at your home instead of sending it back to the grid. If your solar panels are producing more electricity than you need, the excess energy goes towards charging the battery. Later, when your solar panels aren’t producing electricity, you can draw the energy you stored earlier in your battery for night use. You’ll only send electricity back to the grid when your battery is fully charged, and you’ll only draw electricity from the grid when your battery is depleted.

As a bonus, since solar batteries store energy at your home, they also offer short-term backup power in the event that there’s a power outage in your area.
