Why Fitchburg homeowners choose Nexis
From older multifamily homes near downtown to capes and colonials in the hills around Cleghorn and West Fitchburg, Fitchburg homes have real Massachusetts energy costs and real savings on the table. Nexis designs, permits, installs and services solar, batteries, heat pumps, roofing and electrical for Fitchburg families, and we handle the Mass Save and SMART paperwork so you don't have to. Fitchburg is one of the few cities served by Unitil, which runs its own versions of the state programs. We know the Unitil paperwork and file it for you.
Because we're licensed across five trades in-house, your solar, roof, panel and heat-pump work happens on one timeline with one accountable team — not a chain of subcontractors pointing fingers.

What our customers say
Nexis handled our solar, panel upgrade and battery as one project — one crew, one timeline, and they filed every rebate. Painless.
They actually knew the Mass Save program cold and got us the full heat-pump rebate. No other quote came close on value.
Forbes #1 for a reason. Professional, licensed, and they didn't disappear after the install like our last installer did.
