Why Cambridge homeowners choose Nexis
From two- and three-family homes in Cambridgeport and East Cambridge to Victorians near Harvard and Porter Squares, Cambridge 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 Cambridge families, and we handle the Mass Save and SMART paperwork so you don't have to. Cambridge homes are close together and often older, so roof condition, panel capacity and historic review all matter. One licensed team for roofing, electrical and solar keeps the project simple.
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.
