New England's most credible energy team.
Nexis Power is one Forbes #1–ranked, fully licensed team for solar, battery storage, heat pumps, roofing, and electrical — residential and commercial. We handle the SMART enrollment, Mass Save rebates, and permitting so homeowners and businesses across Massachusetts get cleaner, cheaper energy without juggling five contractors.
Who we are
One team for everything your home's energy needs
Most homeowners who want to go solar, replace an oil system, or electrify their home end up managing a solar company, an HVAC contractor, a roofer, and an electrician — each with their own timeline, paperwork, and finger-pointing. Nexis exists to end that. We're licensed across all five trades, so one team designs, installs, and services it all.
That structure is also why we can do things others can't: replace your roof and install solar under one warranty, upgrade your panel in step with your heat pump, and take responsibility for the whole outcome instead of one slice of it.
We're headquartered in Woburn and work across Massachusetts — plus Connecticut, New Hampshire, and Rhode Island — and we're proud to have been named Forbes #1 Best Solar Company in Boston in both 2024 and 2025.
What we stand for
- Credibility over hype. Real numbers, real licenses, real warranties — not "discover more" fluff.
- We carry the paperwork. SMART, net metering, Mass Save, HEAT Loan, and permits — handled by us.
- Premium equipment only. Tier-1 brands, installed to spec, backed by warranties that outlast the loan.
- One point of accountability. Five trades, one team, one outcome you can hold us to.
