Section 9B. Zoning ordinances or by-laws adopted or amended pursuant to section five of this chapter may encourage the use of solar energy systems and protect solar access by regulation of the orientation of streets, lots and buildings, maximum building height limits, minimum building set back requirements, limitations on the type, height and placement of vegetation and other provisions. Zoning ordinances or by-laws may also establish buffer zones and additional districts that protect solar access which overlap existing zoning districts. Zoning ordinances or by-laws may further regulate the planting and trimming of vegetation on public property to protect the solar access of private and public solar energy systems and buildings. Solar energy systems may be exempted from set back, building height, and roof and lot coverage restrictions. Zoning ordinances or by-laws may also provide for special permits to protect access to direct sunlight for solar energy systems. Such ordinances or by-laws may provide that such solar access permits would create an easement to sunlight over neighboring property. [...] Such ordinances or by-laws may further provide for establishment of a solar map identifying all local properties burdened or benefited by solar access permits. Such ordinances or by-laws may also require the examination of such solar maps by the appropriate official prior to the issuance of a building permit.
Full Breakdown
Residential and commercial solar PV systems in Lowell require a building permit and an electrical permit from Inspectional Services. Applicants submit structural analysis, a site plan, electrical line diagrams, and MA UCC-compliant rapid shutdown details. Systems must meet the 2023 Massachusetts Electrical Code and the IRC fire access pathway requirements. Lowell has a Solar Energy Overlay District that allows large ground-mounted solar as-of-right in certain industrial and municipal parcels, consistent with MGL c.40A s.9B. Panels on historic district structures, including downtown and parts of the Acre, require Historic Board approval and generally must be located on rear-facing slopes not visible from the street.
