HDC approves multiple rooftop solar arrays with screening and panel-location conditions

The Nantucket Historic District Commission approved a set of rooftop solar installations across the island with site-specific conditions aimed at minimizing visible impacts from principal public viewpoints.

At 48 Bartlett (commercial rooftop), the board approved the array on the condition that five panels on a highly visible northeast roof plane be removed; the applicant agreed to produce an Exhibit A showing the modified layout. Commissioners said the change reduced visibility from Bartlett Road while preserving the applicant’s capacity to generate power.

On a smaller residential application at 6 Nobadere Way, commissioners accepted the owner’s offer to plant additional Leyland cypress and other screening so the front-facing array would be concealed from public view; the board approved the system subject to that screening being installed and maintained. Commissioners also recommended considering a darker roof color at the time of the next roof replacement to further reduce visual contrast.

At 9 Hawthorne and several other lower-visibility addresses, panels were approved on the understanding the applicants would maintain vegetative screening and minimize visibility from public ways. In each case, commissioners balanced the town’s climate goals and the owners’ energy needs against the HDC’s mandate to preserve historic character and minimize visual intrusion.

Where visibility was a concern the board used targeted mitigation—panel relocation or removal and vegetative screening—rather than outright denial, and noted applicants may return with alternative mounting strategies if the proposed screening fails to mature.
