Donahue & Sons Mgmt Inc. works out of Barre, Massachusetts, a hill town of stone walls and sloping hayfields where the Ware River valley folds into woods and the common sits wide and green at the center of everything. Their ground is the solar field: acres of panel rows to keep clear of encroaching brush through vegetation management, slope and landfill mowing that leaves a hillside combed and open, panel washing, herbicide treatment, fence maintenance, erosion control and soil stabilization, and pollinator establishments seeded where the grass gives way to bloom. Winter turns the work to snow removal, the long aisles opened while the light is still blue over the ridgelines. They also handle Solectria inverter repairs and waste management with dumpster rentals, and they carry all of it from Barre out across the Northeast and Mid-Atlantic. There is a plain satisfaction in a site left tidy and breathing — the cut clean to the fence line, the array facing the sun with nothing in its way.
