Solar Leasing on Land in Barnwell County, South Carolina

A real, multi-project solar buildout already underway

Barnwell County isn't a hypothetical or early-stage solar market -- it already has several distinct, named utility-scale projects on the ground or announced. Cypress Creek Renewables built and operates the Barnwell Solar facility, a roughly 16-acre, 5.44-megawatt photovoltaic farm whose output has been used by the regional utility. Separately, Blackville Solar II is another named operating project in the county, and a project called Crossroads has been in pre-construction status near the town of Elko. On top of those, Barnwell PV 1, LLC has announced a considerably larger $75 million, 60-megawatt solar farm for the county. Taken together, that's a genuine pattern of developers actively working Barnwell County land across multiple project sizes -- not a single isolated deal -- which is useful context if you're trying to gauge whether your own land is a realistic solar-lease candidate and what scale of project a developer might propose.

That said, project status changes fast in this industry -- a facility described as "pre-construction" or "announced" today may be built, delayed, or cancelled by the time you're evaluating your own land, and a landowner should confirm current status of any named project directly rather than relying on this summary as a current snapshot.

Barnwell County's own solar ordinance: specific, real numbers

Unlike a county with no solar-specific rules at all, Barnwell County has adopted its own ordinance governing ground-mounted photovoltaic solar facilities of at least 1 megawatt with three or more ground-mounted collectors intended to sell power -- the scale of project a landowner leasing to a utility-scale developer would actually be part of. The ordinance sets concrete dimensional standards: a minimum 50-foot setback from roadways and a 100-foot setback from adjacent residential property, and it requires the site to be secured by a fence at least 6 feet high. Those numbers matter directly to how much of your acreage would actually be usable for panels versus buffer, and how a project would sit relative to a neighboring house.

The ordinance also addresses what happens at the end of a project's life, which is exactly the kind of detail a general due-diligence checklist won't cover but a solar-specific lease negotiation should: it requires an anticipated-lifespan and decommissioning plan up front, including estimated removal costs, a funding method, and site-restoration procedures. Decommissioning is triggered automatically after six continuous months without electricity generation, with a six-month window to remove all project infrastructure after that. Critically, the county requires a performance guarantee -- either a flat $50,000 or 125% of the estimated decommissioning cost (net of any salvage value), whichever applies -- and that guarantee must be updated annually, which is a real, specific financial-assurance mechanism rather than a vague promise in a lease contract.

What to ask before signing a Barnwell County solar lease

• Whether your parcel's zoning district and location relative to roadways and residential neighbors can actually accommodate the ordinance's 50-foot road and 100-foot residential setbacks at the scale a developer is proposing -- ask Barnwell County Building Inspector & Zoning for a site-specific read before assuming your whole tract is usable.
• Whether the decommissioning bond required by the county ($50,000 or 125% of estimated removal cost, whichever applies, updated annually) is separate from, or is meant to satisfy, any decommissioning-cost provision in your own lease with the developer -- get this in writing rather than assuming the two automatically line up.
• Current status of any of the named projects in the county (Barnwell Solar, Blackville Solar II, Crossroads, Barnwell PV 1) if your land is near one of them, since proximity to an existing project can affect interconnection queue position, developer interest, and local political appetite for further approvals.
• Lease term and renewal structure -- utility-scale solar leases commonly run 20-30 years with renewal options that can extend total commitments considerably further; confirm how that interacts with your own long-term plans for the land.
• Whether the project needs to comply with the South Carolina Solar Habitat Act (pollinator-friendly seed mixes and similar habitat provisions), since that can affect site landscaping and maintenance obligations layered on top of the county ordinance.
