Summary
Bethel requires Planning and Zoning Commission site plan review and a building permit before any large-scale ground-mounted solar photovoltaic installation of 250 kW DC or more is built. The rule sits in the Renewable Energy Overlay Zone provisions of the brand-new Chapter 118 zoning regulations, effective May 15, 2025.
The purpose of this § 118-5.10 is to promote the creation of new large-scale ground-mounted solar photovoltaic installations by providing standards for the placement, design, construction, operation, monitoring, modification and removal of such installations that address public safety, minimize impacts on scenic, natural and historic resources and to provide adequate financial assurance for the eventual decommissioning of such installations. ... Site plan review. Ground-mounted large-scale solar photovoltaic installations with 250 kW or larger rated nameplate capacity shall undergo site plan review by the Commission prior to construction, installation or modification as provided in this section. ... Building permit and building inspection. No large-scale solar photovoltaic installation shall be constructed, installed or modified as provided in this section without first obtaining a building permit.

Full Breakdown
10 of the Bethel Zoning Regulations governs large-scale ground-mounted solar photovoltaic installations, defined as ground-mounted (not roof-mounted) systems with a rated nameplate capacity of 250 kW DC or higher. These installations are permitted only within the Renewable Energy Overlay District established under Article IV, excluding the Village Center Zone, and setbacks match the underlying zoning district. Before construction, installation or modification, an applicant must go through Commission site plan review under Subsection E, submitting Professional Engineer-stamped plans and electrical diagrams, documentation of major components (panels, mounting system, inverter), installer and applicant contact information, proof of liability insurance, a description of financial surety for eventual decommissioning, and an operation and maintenance plan covering safe access and stormwater controls.
A separate building permit is also required before construction under Subsection G(6), and the Commission must approve any material modification made after that permit issues. The applicant must notify the utility operating the local grid of the interconnection (off-grid systems are exempt) and provide the Bethel Fire Department with the project summary, electrical schematic and site plan so an emergency response plan can be developed. Signage on the array may identify the owner and a 24-hour emergency contact but may not be used for advertising. Lighting must be shielded from abutting properties and, where feasible, full-cut-off and downward-directed.
Violations & Fines
An installation is considered abandoned if it stops operating for more than one year without written Commission consent, or if the owner fails to notify the Commission by certified mail of a planned shutdown date. Once abandoned, or once operations end, the owner or operator must physically remove all panels, structures, equipment, security barriers and transmission lines within 150 days and dispose of waste under applicable law. If removal does not happen within that window, the Town may enter the property and physically remove the installation itself, and every approved applicant must grant the Town the license or easement needed to do so.
