Summary
Sussex County lets accessory solar panels serving an existing home or business go up "in all districts" with no conditional-use review under § 115-194.6A. A freestanding solar farm or array that isn't accessory to another use on the lot instead needs a conditional-use permit and must meet the added standards in § 115-172I.
Solar panels and similar uses that are accessory to or ancillary to the principal or permitted use on the same lot shall be permitted in all districts. ... All other solar panels, solar farms or solar arrays shall require a conditional use and shall comply with the requirements of § 115-172I.

Full Breakdown
Added by Ord. No. 6 splits solar into two tracks. Subsection A covers "solar panels and similar uses that are accessory to or ancillary to the principal or permitted use on the same lot," meaning rooftop or small ground-mounted arrays that power a home, farm or business already on site; those are permitted in all districts, so no rezoning or conditional-use hearing is required, only the standard building permit. Subsection B reaches everything else, "all other solar panels, solar farms or solar arrays," and routes them into the conditional-use process, which the chapter's conditional-use framework runs through the Planning and Zoning Commission and County Council at a public hearing, plus the added site standards written into § 115-172I specifically for solar facilities.
A commercial solar farm sited on undeveloped acreage rather than serving an on-site use is the kind of project that falls into the conditional-use track; a homeowner's rooftop array or a farm's panel bank tied to its own barn does not. Sussex County's conditional-use uses elsewhere in the same Article, such as borrow pits and manufactured home parks, follow the same County Council approval pathway, underscoring that a large-scale solar array is treated as a discretionary land use rather than a permitted one.
Violations & Fines
Solar installations fall under Chapter 115's general zoning penalty at § 115-229: violating the chapter, including building or operating a solar array without the required permit or conditional-use approval, is a misdemeanor punishable by a fine of up to $100, and each day the violation is permitted to exist constitutes a separate offense. A contractor or agent who assisted in the violation is separately liable for the same fine.
