Commercial energy that cuts operating costs.
Nexis is one licensed team for commercial solar, battery storage, heat pump HVAC, O&M, and interconnection. We build SMART-for-business, net metering, and the federal 48E ITC into a clear ROI model — then design, install, and service the system, so energy becomes a managed cost instead of a rising one.
For business owners
One team for your building's energy
Businesses waste money and time coordinating separate vendors for solar, storage, HVAC, and electrical. Nexis brings them under one licensed roof: we assess your building, model the incentives, engineer the systems, manage interconnection, and provide long-term O&M — so you have a single accountable partner for the energy side of your P&L.
Whether it's a rooftop solar array, a demand-charge-shaving battery, a heat pump HVAC retrofit, or all three, we build the business case first and the system second.
What we do for commercial clients
- Commercial solar — rooftop and ground-mount PV modeled around SMART, net metering, and 48E ITC.
- Battery storage — peak-demand reduction and resilience, with demand-charge modeling.
- Heat pump HVAC — efficient VRF and heat pump systems for commercial and multifamily buildings.
- Interconnection — National Grid / Eversource / Unitil applications and studies, managed.
- O&M & monitoring — keep systems performing across their 25-plus-year life.
- One licensed team — solar, electrical, HVAC, and roofing under one contract and timeline.

Commercial incentives that pencil in 2026
Commercial SMART (20-year term, adders), net metering, and the federal 48E ITC with domestic-content bonus remain available for qualifying business systems, and Mass Save offers commercial HVAC incentives (about $2,000/ton up to 35 tons for heat pumps; a Rebate Commitment Letter sets a hard figure beyond that). We model them into your ROI. (Figures verified per project.)

Commercial FAQ
Answers for business
We work across light and mid-size commercial and multifamily — from smaller rooftop arrays to larger systems, plus commercial HVAC and storage. We'll scope the right approach at your ROI analysis.
Commercial SMART (20-year term with adders), net metering (with the 60% market-credit rule above 25 kW AC), and the federal 48E ITC with a domestic-content bonus. 48E continues for commercial projects. We model all of it.
Often, yes. Battery storage paired with solar can shave peak-demand charges on commercial accounts. We model the specific demand-charge savings for your building.
Yes — we manage the full interconnection process and provide ongoing operations and maintenance so systems keep performing.
