Home Solar Solar + Battery Backup
FORBES #1 Best Solar Company in Boston

Solar + battery — power that never blinks.

Pairing owned solar with a home battery is the most resilient setup a Massachusetts homeowner can own: your panels cut your bill through net metering and SMART every day, and when the grid goes down your battery keeps the home running — recharging from the sun the next morning. Nexis designs the whole system as one project.

Why solar + battery together

Savings every day, resilience every storm

Solar alone lowers your bill; a battery alone gives you backup. Together, they give you both — and they cover each other's weak spot. During a multi-day outage, a solar-plus-battery home recharges each day from the sun instead of running a battery flat, so you stay powered as long as the weather cooperates.

Nexis engineers the array, storage, backup panel, and electrical as a single project on one timeline, so the system is balanced correctly and everything is covered by one workmanship warranty.

What a solar + battery system delivers

  • Daily bill savings — net metering credits and the 20-year SMART production incentive on your owned solar.
  • Automatic outage backup — the battery carries your critical loads the moment the grid drops, with no generator.
  • Daily solar recharge — during extended outages your panels refill the battery each morning.
  • Right-sized design — array and storage balanced to your usage and the circuits you want protected.
  • ConnectedSolutions earnings — eligible batteries earn seasonal incentives for peak-event participation.
  • Warranties that outlast the loan — 25-yr solar performance, long-term battery coverage, 25-yr workmanship.

The 20-year solar incentive

SMART 3.0 pays your panels back

Your owned array earns Massachusetts' SMART 3.0 production incentive — a per-kilowatt-hour payment for 20 years — stacked on top of full-retail net metering, and pairing a battery can add a storage adder to the tariff. We model your exact SMART value at your assessment.

See the details on our Massachusetts solar incentives page, or visit the official Massachusetts SMART 3.0 website.

Earn money with your battery

ConnectedSolutions in Massachusetts

Once your battery is in, Nexis can enroll it in ConnectedSolutions — the Mass Save program that pays you to share a little stored power during summer peak-demand events. Your home stays powered; the utility just pulls from your battery instead of an expensive peaker plant.

Massachusetts rewards solar + storage

Owned solar earns net-metering credits and the 20-year SMART incentive, while an eligible battery can earn ConnectedSolutions payments. Stacked, they shorten payback and add resilience. (Figures as of 2026, verified at your assessment.)

Solar + battery FAQ

Answers, straight up

A standalone battery drains during a long outage. Paired with solar, it recharges from the sun each day, so you can stay powered through multi-day outages. And the solar cuts your everyday bill through net metering and SMART, which a battery alone doesn't.

It can, depending on how the system is sized. Most homeowners back up essential circuits (heat, fridge, lights, internet, well/sump) for the best value; whole-home backup is available with larger storage. We design to your priorities.

Yes. The solar portion earns net-metering credits (systems under 60 kW) and the 10-year residential SMART production incentive. Nexis files both for you.

Absolutely — we design every solar system to be battery-ready, so you can add storage now or later without re-engineering the array.
