The Mansfield letter emphasizes that “ . . . the strong statutory protections for solar installations and related structures such as ESS in G.L. c. 40A, § 3, and the [Supreme Judicial Court’s recognition in Tracer Lane II v. City of Waltham, 489 Mass. 775 (2022)] that large-scale solar and related structures ‘are key to promoting solar energy in the Commonwealth.’”
