Serving up clean energy on an island that runs on fossil fuels and ferry logistics.

We create solar solutions built for Nantucket's unique demands — marine-grade engineering, HDC-compliant design, and an approachable, expert, local team that knows this island inside and out. 

We’re not just Nantucket’s solar company–

we’re your neighbors.

HDC expertise, not just experience

Nantucket’s Historic District Commission requirements aren’t a formality — a rejected submission adds months to your project timeline and stress you don’t need. We’ve navigated the HDC process more than any other solar installer on the island, achieving a 75% first-submission approval rate.

We design for the HDC from day one: system placement, panel color, hardware visibility, and landscaping integration are all considered before the first drawing goes out.

Marine-grade materials

Nantucket's salt air does things to hardware that mainland installers never account for. We spec stainless steel fasteners and marine-grade mounting components on every install — not because it's required, but because we know what this environment does to standard hardware over 20 years.

We also build proactive spot checks into every maintenance plan, catching corrosion before it becomes a problem. It's the difference between a system that performs for 10 years and one that performs for 25.

Prompt and local island response

When something goes wrong with a high-value property, you can’t afford to wait. Off-island contractors need to catch a boat — then find a hotel. Our team is already here, year-round, responding within 24 hours for every client no matter the season.

For seasonal homeowners managing a property remotely, that responsiveness isn’t a convenience. It’s the whole point.

  • "ACK Smart did a great job on our solar system, which was installed in Sconset earlier this year. Cleared the HDC approval process with nary a hitch and the installation was done in no time. The system is now cranking out lots of free power and should pay for itself in under a decade. Tim and the rest of the team are responsive and easy to deal with. Would highly recommend."
