First Solar (FSLR) opens $330 million South Carolina facility as U.S. solar manufacturing strategy expands

First Solar, Inc. (NASDAQ: FSLR), the American thin-film solar module manufacturer, is inaugurating the first phase of its approximately $330 million production facility in Gaffney, South Carolina, on October 28, 2026, adding another operating location to its expanding U.S. manufacturing network. The Cherokee County facility currently employs approximately 500 people, with staffing expected to increase to nearly 700 by mid-2027 when the second development phase is scheduled for completion. The plant will carry out final production processes for First Solar’s Series 6 Plus modules, using products initiated at the company’s international manufacturing facilities rather than establishing a completely independent domestic cell production operation. Its commercial importance lies in how the additional finishing capacity could improve supply-chain flexibility, tariff exposure and access to applicable domestic manufacturing incentives while supporting demand for American-produced solar equipment.

First Solar announced the South Carolina investment in November 2025, committing approximately $330 million to a facility at 121 Logistics Drive in Gaffney. The project was intended to begin operations during the second half of 2026, with the latest announcement confirming the inauguration of its initial operating phase.

The event is scheduled to include First Solar Chief Executive Officer Mark Widmar and representatives of the South Carolina government. The manufacturing milestone follows substantial investment in American solar technology across Ohio, Alabama and Louisiana.

The inauguration does not mean that every part of the facility has been completed. Management expects the second phase to become operational by mid-2027, and the economic impact will depend on how efficiently the two phases can be integrated into First Solar’s wider production network.

Why is First Solar investing $330 million in South Carolina instead of building another conventional solar module factory?

First Solar’s South Carolina investment follows a different manufacturing model from its fully vertically integrated American facilities. The new site is designed to complete production processes for solar modules whose initial manufacturing stages take place internationally.

This approach enables the group to use existing manufacturing infrastructure overseas while moving selected final production activities into the United States. It may provide flexibility in managing transport requirements, production schedules and the regulatory treatment of finished modules.

The distinction matters because a manufacturing plant carrying out final processing is not economically identical to a factory producing every component from raw materials. Its investment requirements, employment structure and contribution to domestic manufacturing capacity can differ.

First Solar operates a global network of thin-film production facilities. Its technology is based on cadmium telluride rather than the conventional crystalline silicon architecture used by many competing solar manufacturers.

The company has developed substantial manufacturing and research capabilities in the United States while retaining international production operations. South Carolina creates another point at which the group can coordinate output across those facilities.

The strategy may help First Solar respond to changes in American trade rules and domestic content requirements. However, the financial treatment of any particular module depends on applicable regulations, production processes and contractual arrangements.

Completing production in the United States does not automatically establish that a module satisfies every domestic content requirement or qualifies for every available tax benefit. Those outcomes must be assessed under the relevant rules.

The Gaffney project therefore represents an operational investment with potential regulatory and commercial advantages, rather than a simple addition of fully integrated American cell production.

How much manufacturing capacity will the completed Gaffney facility add to First Solar’s network?

During its second-quarter 2026 earnings call, First Solar said the completed South Carolina facility was expected to provide up to approximately 3.5 gigawatts of finishing capacity for modules initiated at international manufacturing sites.

The figure provides a useful measure of the facility’s intended scale, but it must be interpreted correctly. Finishing capacity represents the amount of module production that can pass through the relevant final manufacturing processes.

It should not be added mechanically to First Solar’s fully integrated domestic cell manufacturing capacity as though all 3.5 GW represented additional solar cells produced entirely in the United States.

The distinction is especially important when assessing the company’s wider manufacturing targets. First Solar has invested in new factories across several states and expects significant domestic production capability as its expansion programme progresses.

Some earlier descriptions of the South Carolina project referenced approximately 3.7 GW of capacity. The company’s subsequent second-quarter commentary provided a more recent operating reference of up to 3.5 GW of finishing capacity.

The October 27 inauguration announcement itself does not publish a revised capacity figure. Investors should therefore distinguish that earlier guidance from any future production target management may provide.

Actual output will depend on commissioning, equipment performance and the supply of partially completed modules from overseas factories. A finishing line cannot operate at full utilization without sufficient compatible upstream production.

The second phase is also relevant because full utilization may require supporting equipment and operational systems that are not available during the initial phase. Successful commissioning will be more meaningful than installed theoretical capacity alone.

Why does the second phase in mid-2027 matter for production efficiency and employment?

First Solar expects the South Carolina workforce to increase from approximately 500 employees to nearly 700 by mid-2027. The expansion is associated with completion of the project’s second phase.

The difference represents approximately 200 additional positions compared with the current workforce. However, the company has not disclosed a detailed hiring timetable or the allocation of jobs across specific production functions.

The phased development approach allows initial operations to begin while additional equipment and processes are prepared. This can reduce the delay between construction expenditure and the commencement of manufacturing activity.

Nevertheless, operating a partially completed facility can introduce temporary inefficiencies. Production processes may need to be coordinated around the equipment already available, while additional installation work continues.

First Solar has identified the incorporation of its CuRe technology as one reason for the revised second-phase timetable. Management said in July that completing the second phase in mid-2027 would allow earlier integration of the technology into the South Carolina operation.

CuRe is part of First Solar’s work to improve the performance and durability of its thin-film modules. Introducing the technology within a production expansion could reduce the need for subsequent modifications.

The financial benefit will depend on whether the manufacturing changes improve product performance, production yield or customer value without creating excessive additional costs.

For South Carolina, the project creates manufacturing employment and demand for supporting services. However, the announced job total should not be expanded into speculative estimates of indirect employment without supporting economic analysis.

How could domestic finishing capacity affect tariffs, U.S. manufacturing incentives and First Solar’s margins?

American solar manufacturing economics are influenced by import duties, domestic content rules and federal manufacturing incentives. These measures can affect the relative cost of equipment produced through different international supply chains.

First Solar’s South Carolina strategy is designed partly to improve flexibility in responding to that environment. Completing final production stages domestically may alter how products are classified or treated under applicable rules.

The company has also identified the relevance of Section 45X manufacturing tax credits. These incentives can provide meaningful support to qualifying domestic solar manufacturing activity, subject to statutory requirements and regulatory guidance.

However, the value of a potential tax credit depends on the specific production activity and whether the relevant requirements have been met. It would be inappropriate to assume that the full 3.5 GW of finishing capacity automatically qualifies for the same benefit as a fully integrated domestic production process.

Tariff exposure presents another consideration. First Solar’s international operations can be affected by trade restrictions and changes in the cost of imported materials or partially completed products.

A more flexible network may allow management to adjust production allocation in response to changing economics. That could improve competitiveness if the benefits of domestic processing exceed the additional logistics and manufacturing expenditure.

The company has not disclosed a standalone gross margin or earnings forecast for the Gaffney operation. Consequently, investors cannot reliably calculate the facility’s annual profit contribution using the announced investment and capacity figures alone.

The strongest financial evidence would involve production costs, tax credit recognition, logistics savings and customer pricing after the facility reaches stable operating conditions.

What do First Solar’s latest financial results reveal about the investment behind its U.S. expansion?

First Solar reported second-quarter 2026 net sales of approximately $1.06 billion, a decline of 4% from the corresponding period of 2025. Management attributed the reduction primarily to lower revenue associated with customer contract terminations, partially offset by increased module deliveries.

Despite the revenue decline, net income increased to approximately $423 million from $342 million a year earlier. Diluted earnings per share rose 23% to $3.92 from $3.18.

The company reported adjusted EBITDA of approximately $644 million for the quarter. Its financial results demonstrate substantial earnings generation while the business continues investing in manufacturing expansion.

First Solar also reported a net cash balance of approximately $1.7 billion at June 30, providing resources to support capital expenditure and operating requirements.

Its contracted sales backlog stood at 45.1 GW at the end of the second quarter. The backlog gives the company visibility over expected future deliveries, although fulfillment and revenue recognition depend on contractual schedules and performance requirements.

For the full year, management reaffirmed guidance for net sales between $4.9 billion and $5.2 billion, with projected module sales of 17 GW to 18.2 GW.

Adjusted EBITDA was expected to range from $2.6 billion to $2.8 billion, while planned capital expenditure stood between $800 million and $1 billion.

The guidance also assumed substantial Section 45X manufacturing tax credit benefits. This demonstrates the importance of federal policy to the company’s reported profitability and operating outlook.

The South Carolina facility is one component of that wider manufacturing strategy. Its economic contribution should be assessed alongside other investments rather than treated as the sole driver of First Solar’s earnings performance.

Why is First Solar expanding U.S. solar manufacturing while domestic demand and trade policy remain uncertain?

The American electricity market is experiencing increasing attention to generation capacity as data centres, industrial activity and electrification create additional demand. Solar projects can contribute new generation capacity, but their commercial viability depends on financing, interconnection arrangements and electricity market conditions.

First Solar is positioning its domestic manufacturing network to serve utility-scale customers seeking reliable equipment supply and greater visibility over production origin.

Its contracted backlog indicates substantial existing customer commitments. However, new bookings, order cancellations and changes in project schedules can affect the value and timing of future deliveries.

Trade policy introduces additional uncertainty. Import duties may improve the relative competitiveness of some domestic production activities while raising costs for materials or products sourced internationally.

Federal incentives can also influence factory profitability and customer purchasing decisions. Changes to those incentives could alter the economics of both existing operations and future investments.

First Solar’s South Carolina plant is particularly relevant because it combines international production with domestic finishing. The model provides flexibility but also exposes the business to questions about the regulatory treatment of products crossing borders at different manufacturing stages.

The company must also compete with solar manufacturers using crystalline silicon technology, including producers with substantial international capacity.

Its thin-film technology provides differentiation, but product performance, pricing, reliability and delivery schedules will remain important to customer purchasing decisions.

The investment case therefore depends on sustained commercial demand and competitive manufacturing economics, not merely the completion of new facilities.

How does the Gaffney facility fit First Solar’s wider American manufacturing footprint and supply chain?

First Solar’s American manufacturing expansion includes major facilities in Ohio, Alabama and Louisiana. These sites support the company’s vertically integrated thin-film production network.

The South Carolina operation extends that footprint through final manufacturing processes associated with international production. The company also operates a distribution centre in Duncan, South Carolina, and maintains a relationship with Inland Port Greer.

These logistics arrangements may be useful in coordinating movement of materials and finished equipment. Proximity to established transport infrastructure can reduce some distribution complexity, although the company has not disclosed the savings expected from the location.

The Gaffney facility is situated within Cherokee County’s industrial economy, where manufacturing employers can draw upon regional workforce and transportation infrastructure.

South Carolina approved job development credits associated with the project, reflecting state support for the investment. The announcement does not quantify the total realized value of those incentives.

The company is also developing a broader American supply chain intended to support manufacturing operations across multiple states. Domestic procurement can potentially improve resilience and reduce exposure to particular international supply disruptions.

However, the value of local sourcing depends on product availability, costs and manufacturing quality. A supplier located within the United States is not automatically more competitive than an international alternative for every component.

The Gaffney plant’s contribution will ultimately be measured through its ability to deliver completed modules reliably and at an attractive cost.

How did FSLR shares perform ahead of the South Carolina inauguration, and what are investors assessing?

First Solar shares closed at approximately $175.85 on Nasdaq on October 27, 2026, rising about 4.6% from the previous session’s $168.15 closing price.

The company’s October 27 announcement confirmed that the South Carolina inauguration would take place the following day. However, the share-price movement cannot be attributed exclusively to that event because the stock is also influenced by solar-sector sentiment, policy developments and earnings expectations.

The stock remained substantially below its June 2026 high, reflecting the volatility associated with changing expectations for American solar manufacturing and renewable energy investment.

Investors evaluating the Gaffney facility may view it as evidence that First Solar is executing its manufacturing strategy despite sector uncertainty.

A constructive interpretation would emphasize the added processing capability, domestic employment, contractual backlog and potential advantages from supply-chain flexibility.

A more cautious assessment would focus on the limited standalone financial disclosure, dependence on international upstream manufacturing and the possibility that regulatory changes affect the value of domestic finishing activities.

The company has not published a specific earnings-per-share contribution from the South Carolina facility. It would therefore be premature to quantify the impact on shareholder value using only the announced investment and employment figures.

The next important disclosures will involve commissioning progress, production utilization and any updated financial guidance that incorporates the completed phases.

What will determine whether First Solar’s $330 million Gaffney facility creates lasting shareholder value?

The immediate milestone is successful operation of the first phase following its October 28 inauguration. Production output and quality consistency will be central to establishing the facility’s operating readiness.

The second milestone is completion of the remaining development work by mid-2027, including the planned expansion of employment to nearly 700 people.

Management will also need to demonstrate that the finished modules can be integrated into customer deliveries without unnecessary transport or production bottlenecks.

The economic benefits will depend on the interaction of manufacturing costs, product performance, tariff exposure and applicable incentives.

A fully utilized facility could improve operating flexibility and support higher module deliveries, provided demand remains sufficient and the upstream production network supplies compatible material.

Conversely, underutilization could increase the cost associated with each unit processed and weaken the expected return on investment.

First Solar’s substantial backlog and existing financial resources support its ability to continue execution. However, the financial return from Gaffney must still be demonstrated through operating performance.

The South Carolina inauguration is therefore an important manufacturing milestone, but not the end of the investment process. Its longer-term significance will emerge when both phases are operational and the company can show that additional American finishing capacity improves the economics of supplying utility-scale solar customers.
