Summary
Clarksville permits solar panels as a utility accessory use subject to setbacks. The distinctive local requirement is code section 4-310: any grid-tied generator needs a lockable, accessible load-break disconnect switch approved by CDE Lightband.
Electric generators of any type and size, interconnected to CDE Lightband's (CDE) electric grid in any way, shape, form, fashion, or means, including wind, solar, fuel cell, reciprocating engine, hydro, and other similar electric generation devices, are required by CDE to install a load-break AC disconnect or transfer switch (Switch) between CDE facilities and the interconnected customer's equipment.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 110 Update 2 | Zoning Ordinance: Supplement 6).
Full Breakdown
The switch sits on the customer's side of the interconnection, isolates automatically when CDE power is lost and manually on demand, stays accessible to CDE personnel at all times, sits near CDE's point of delivery, shows a visible open point, accepts a padlock in the open position, and is labeled Generator Disconnect Switch or Generator Transfer Switch. Failing to notify CDE, or installing a non-conforming switch, brings immediate disconnection of electric service. Reconnection follows inspection and approval by the Building and Codes Department. Clarksville has adopted the 2017 National Electric Code and the 2018 International Building Code, and an electrical permit is required before wiring changes.
Violations & Fines
Non-notification or a non-conforming switch results in immediate disconnection of electric service by CDE Lightband. Service returns only after the switch passes Building and Codes inspection.
