Rooftop solar is strongly protected in Massachusetts. State zoning law bars towns from prohibiting or unreasonably regulating solar systems, so a homeowner mainly needs a building and electrical permit plus a net-metering agreement with the utility.
Massachusetts law favors solar. Under MGL c.40A §3, no zoning bylaw may prohibit or unreasonably regulate a solar-energy system except to protect health, safety, or welfare, so towns like Northampton, Amherst, and Easthampton cannot zone rooftop panels away. A homeowner still needs a building and electrical permit under the state Building Code (780 CMR), with wiring meeting the electrical code and a fire-access pathway on the roof. The system connects to the grid under a net-metering agreement with the serving utility, usually Eversource or National Grid, though some Valley towns run municipal light plants. The state SMART program and DPU net-metering rules add incentives.
Energizing a system without an interconnection agreement forces disconnection, and unpermitted or unlicensed electrical work fails inspection and draws town building-code enforcement, with retroactive permits and fines.
