Suniva Closes $835 Million for a 4.5 GW South Carolina Cell Plant That Will Not Ship Until 2028

Key Facts
  • Suniva completed an $835 million capital raise combining debt and equity financing
  • The Laurens County, South Carolina plant will add 4.5 GW of monocrystalline silicon cell capacity
  • Suniva puts the project at roughly $600 million and 564 permanent manufacturing jobs
  • Completion is expected in late 2027, with a full production ramp in 2028
  • Section 232 sets a 22-cent-per-watt minimum import price for solar cells plus 15% ad valorem tariffs

Suniva has closed an $835 million capital raise for its second US solar cell plant. The money funds a 4.5 GW factory under construction in Laurens County, South Carolina. The building shell is already finished. Suniva expects to complete the plant in late 2027 and to reach full production in 2028.

The raise mixes debt and equity. Goldman Sachs Alternatives and I Squared Capital arranged senior secured credit facilities through managed funds. JBA Asset Management provided a second lien credit facility. Electron Capital Partners, Orion Infrastructure Capital and Rubric Capital Management put in equity, and Lion Point Capital, already the company’s largest shareholder, took part as well.

What The Money Buys

The Laurens County building runs 621,468 square feet. Suniva puts the project cost at roughly $600 million and permanent headcount at 564. The company already runs a 1 GW cell factory in Norcross, Georgia. Adding South Carolina takes total US capacity to 5.5 GW.

The expansion lands in the middle of a Section 232 trade action. That action sets a minimum import price of 22 cents per watt for solar cells. Ad valorem tariffs of 15 percent sit on top of the floor. Finished module prices have climbed to levels last seen during the 2023 anti-circumvention inquiry into Southeast Asian production. A high import floor makes domestic cell production more profitable, and that is the wager behind this factory.

Suniva describes the project as de-risked by a domestic supply chain already in place. It also points to long-term offtake agreements covering most of the plant’s planned output. The company signed a definitive reverse merger agreement with Nasdaq-listed SUNation Energy in June 2026. A 2023 plan to expand the Norcross plant to 3.5 GW appears to have given way to the South Carolina build.

Why It Matters

Two numbers in this announcement do not sit flush. Suniva raised $835 million for a project it prices at about $600 million. The company has not broken out what the remaining capital does. Refinancing, working capital and financing costs are the ordinary answers. None of them appear in the announcement.

The structure matters more than the headline figure. Senior secured debt and a second lien facility both carry service obligations from the day they close. The first cell off the South Carolina line is more than a year out, which leaves a single 1 GW plant in Georgia carrying the revenue in the meantime.

Buyers weighing those long-term offtake agreements have a sharper question to ask. The plant’s economics rest on an import floor set by trade policy, not by a contract. Ask what happens to the offtake price if the 22-cent floor moves before 2028.

Critical Perspective

The gap between the two headline numbers goes unexplained. Suniva raised $835 million for a project it prices at about $600 million. No source in this set says what the remaining capital does.

The plant’s economics rest on trade policy rather than on a contract. A 22-cent floor plus a 15 percent tariff makes domestic cell production pay at today’s prices. Suniva points to long-term offtake agreements as de-risking, and none of these sources says whether those offtakes are priced against the floor or set independently of it. That distinction decides who carries the risk if the floor moves.

One claim in the announcement travels unchecked. Suniva describes itself as the only US-owned solar cell manufacturer at commercial scale. That line comes from the company’s own statement, and no source here tests it.

The company has redirected an announced expansion once already. A 2023 plan would have taken the Norcross plant to 3.5 GW. pv magazine writes only that the South Carolina build seems to have superseded that plan, and Suniva has not said so plainly in these sources. The record here shows one shelved expansion and one larger expansion now funded.
