Commercial Solar

Solar for warehouses, offices, and industrial roofs

Cut operating costs and lock in your kWh rate for 25 years.

Commercial work is different — bigger systems, different financing, MACRS depreciation, and usually a roof that's been ignored. We size every commercial job around your demand profile and the available roof or ground area.

We work with REC panels and SolarEdge string inverters for most commercial installs (better economics at scale than microinverters). Pricing is $2.50/W installed.

We've installed for businesses across RI, MA, and CT — small office buildings, warehouses, agricultural operations.

How it works

01

Energy audit

We pull 12+ months of utility data, model your demand, and design around it.

02

Financing path

We walk you through Sunstone Credit (commercial financing), MACRS depreciation, and the 30% federal ITC.

03

Engineering

Stamped plans, structural roof analysis, interconnection study with the utility.

04

Install + commission

Crews scale to project size. Most 100–250 kW jobs land in 2–4 weeks.
