Use the free estimator for a preliminary layout, or share your preferred response method with the commercial team. Final feasibility still requires site, utility, and engineering review.
Plan roof, ground-mount, or carport solar from the property's real load, utility tariff, site constraints, and current program rules. In Massachusetts, NuWatt's in-house engineers design and install the project — a direct EPC, not a lead reseller.

Documented NuWatt installations
NuWatt's portfolio includes 12 completed commercial and institutional projects. The first search-release case study documents the 55 kW ground-mounted solar array at Pleasant Valley Gardens in Methuen, MA.

It can be, but the answer must be modeled from the facility rather than a statewide average. Use the serving utility and rate class, 12 months of usage, interval demand where available, a site-specific production model, the EPC quote, and only incentives the project can document. This page separates current official program facts from customer inputs and modeled results.
The Section 48E begin-construction window closed July 4, 2026: projects that began construction on or before that date may use the longer continuity pathway. Commercial solar projects starting now generally must be placed in service by December 31, 2027. The statutory credit is 6%; it can increase to 30% when the applicable prevailing-wage and registered-apprenticeship requirements are met. Commercial tax credit guide →
IRS Notice 2025-42 · verified 2026-08-06The value comes from the facility's real load, tariff, site, and tax position—not a generic statewide payback.
Generating power on-site turns a variable grid charge into a fixed project cost you can model for the life of the system in Massachusetts.
Model the 6% statutory Section 48E credit, the increase to 30% when PWA rules are met, and 100% first-year bonus depreciation only when your tax team confirms eligibility.
Lower electricity spend flows straight to operating income — a durable line-item reduction, not a one-time rebate.
On-site clean generation supports emissions targets and the sustainability requirements tenants, investors, and municipalities increasingly ask for.
Program decision layer
Official program facts are separated from customer inputs and modeled results so a planning number cannot be mistaken for an approved incentive or a measured outcome.
Current Massachusetts program
Program Year 2026 has 600 MW AC available subject to the program cap. Projects above 25 kW AC use the base compensation tier below; behind-the-meter projects must also apply DOER's project-specific value-of-energy calculation. Location, off-taker, and other adders are separate eligibility tests.

Statewide PY2026 base compensation rates (DOER, Table 5). Systems ≤25 kW instead earn a flat $0.03/kWh incentive ($0.06 low income). Adders are separate — add them into the rate below.

Behind-the-meter mechanic: incentive = (compensation rate − value of energy) × generation. SMART tops up the value you already capture through bill offset, so a higher value of energy lowers the SMART payment.
Estimates only. SMART 3.0 base compensation rates are statewide by system-size category and reset annually by DOER (draft PY2027 rates due Oct 1, 2026; final Dec 1, 2026), with any step-down capped at 20% per year or 1¢. The seeded figures are the PY2026 base rates; use the exact rate on your Statement of Qualification, which fixes it for the 20-year term. Confirm figures with your installer and the current DOER program documents.

One in-house engineering and install team, from first analysis through commissioning.
We model your building's real usage, roof, and Massachusetts utility tariff, then engineer a system sized to your load and budget.
Our licensed crews handle permitting, interconnection, and installation, then commission and inspect the system so it powers up to spec.
At handoff your team gets production visibility through the manufacturer portal (Enphase or SolarEdge), backed by our workmanship warranty and support line.

A defensible project cost comes from an EPC quote built on the roof or site, structural scope, electrical equipment, labor rules, interconnection work, and schedule. The calculator on this page requires the quoted cost rather than supplying a statewide per-watt average.
