Solar plus storage

Homeowners in New England often see significant power outages from Nor'easters, hurricanes, high winds, severe thunderstorms and other natural events. Sometimes even human error — such as a traffic accident or a backhoe severing a powerline — can take down your grid power. Now, many across Massachusetts from the North shore down to the South shore are adding backup battery power to their rooftop solar panels.

Energy Storage 24/7

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.


Easy Backup Power for Hurricanes

Installing Powerwall with Boston Solar is easy. We take care of everything from system design to installation from the professional Boston Solar Powerwall Certified Installer team.


What’s in Tesla Powerwall?

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.


Why Add Tesla Powerwall to Your Home Solar?

Adding Powerwall to your residential solar system can give you access to a number of benefits:

  • Increasing 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.
  • Load shifting - 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.
