Solar plus Storage

Easy Backup Power for Nor'easters and Hurricanes

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. We now offer customized solar-plus-battery solutions that enable you to access the free, abundant power of the sun and reduces your reliance on fossil fuels. Installing batteries with Boston Solar is easy. We take care of everything from system design to installation.


Battery Storage 24/7

With battery storage, 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.


Why Battery Storage to Your Home Solar?

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

  • Increasing self-consumption of solar power generation - Batteries can store surplus solar energy during daylight hours and use that energy later when the sun is not shining.
  • Load shifting - Batteries 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.
Generac PWRcell Battery

What is pwrcell?

Generac PWRcell is an intelligent energy storage system. Equipped with PWRview energy monitoring technology, PWRcell protects homeowners during times of power outage and allows them to time-shift their energy usage to save on utility costs.

  • Gain greater independence from the grid PLUG-AND-PLAY


Tesla Powerwall

What is 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.


What is Sonnen eco?


The sonnenBatterie residential and commercial storage systems only use lithium-ion iron phosphate (LiFePO4) battery technology, one of the most reliable, safe and long-lasting lithium battery technologies currently available. 

The Sonnen is a smart energy storage solution for homes that uses intelligent software to manage energy usage throughout the day – providing homeowners with greater energy management during peak time-of-use periods, backup power during grid outages and a powerful way to store solar energy for use day or night.

Boston Solar offers multiple Sonnen eco and Sonnen ecoLinx batteries. These range in capacity from 5-20 kWh. Sonnen battery systems are AC coupled, this makes them compatible with any existing solar inverter.
