First Solar Inc. (FSLR) Business & Investor Dossier

First Solar makes money primarily by selling solar panels (photovoltaic modules) to utility-scale solar project developers, independent power producers, and electric utilities. The company manufactures and sells its Series 6 and Series 7 cadmium telluride (CdTe) thin-film solar modules under long-term supply contracts, typically signed years in advance of delivery. This forward book of orders provides revenue visibility that is unusual among solar panel manufacturers. First Solar earns revenue from module sales (the dominant revenue source) and from systems sales (where it also develops, builds, and sells completed solar projects). The company benefits from the Inflation Reduction Act's Section 45X manufacturing production tax credit, which provides a direct subsidy per watt of solar modules manufactured in the United States, significantly boosting profitability.

First Solar uses cadmium telluride (CdTe) thin-film technology rather than crystalline silicon (c-Si), which is the dominant technology used by Chinese solar manufacturers (Jinko Solar, LONGi, Trina Solar) and most other panel makers. CdTe panels are deposited as a thin semiconductor film on glass, requiring less raw material and a different manufacturing process than silicon panels. First Solar's CdTe panels have historically had slightly lower efficiency than premium monocrystalline silicon panels but have also had distinct advantages: better performance in high-temperature and diffuse-light conditions, lower temperature coefficient (less efficiency loss when hot), and lower carbon footprint per watt in manufacturing due to less energy-intensive production. First Solar's CdTe technology also requires no silicon (avoiding supply chain dependence on Chinese silicon polysilicon), no silver (a cost driver for silicon panels), and no Chinese manufacturing inputs -- a significant advantage for U.S. utility customers concerned about supply chain security or domestic content requirements.

The Inflation Reduction Act (IRA), signed into law in August 2022, has been transformative for First Solar in two ways. First, Section 45X of the IRA provides a manufacturing production tax credit of approximately $0.07 per watt for solar modules manufactured in the United States. For First Solar, which manufactures entirely in the U.S. (with plants in Ohio, Alabama, and Georgia), this represents a significant per-module subsidy that directly flows to gross profit. The Section 45X credit is worth hundreds of millions of dollars annually to First Solar. Second, the IRA's investment tax credits and production tax credits for solar energy projects accelerated demand for utility-scale solar across the U.S., filling First Solar's order book years into the future. As the dominant U.S. solar manufacturer with no Chinese supply chain, First Solar also benefits from provisions requiring domestic content for maximum ITC incentives, which makes its U.S.-made panels preferable for developers seeking the full credit.

First Solar's competitive advantages over Chinese solar manufacturers include: U.S. manufacturing, which qualifies for IRA Section 45X production credits and domestic content bonuses for customers; supply chain security, as First Solar's CdTe process does not depend on Chinese polysilicon, wafers, or cells; no Xinjiang supply chain risk (Chinese silicon solar panels have faced scrutiny under the Uyghur Forced Labor Prevention Act due to polysilicon sourcing from Xinjiang, creating import barriers); premium positioning in utility-scale projects that require bankable, reliable suppliers; and First Solar's unique end-of-life module recycling program (it reclaims cadmium from old panels), which addresses customer concerns about the environmental impact of CdTe. The IRA's domestic content provisions effectively penalize Chinese-sourced panels by reducing available tax credits for customers using non-domestic content, while rewarding First Solar's U.S.-made modules.

First Solar's main risks include: policy risk from potential changes to IRA manufacturing credits (Section 45X) or investment tax credits, which are integral to its economics and competitiveness; technology risk from silicon solar panel efficiency improvements that could narrow or eliminate CdTe's advantages; commodity risk from cadmium and tellurium prices (tellurium is a rare byproduct of copper refining with limited supply); execution risk on manufacturing capacity expansion across multiple U.S. facilities; project development execution risk when First Solar builds systems (complete projects) rather than just selling modules; and competitive risk from both Chinese manufacturers finding ways around import restrictions and from new entrants building U.S. manufacturing capacity. First Solar's business is also concentrated in utility-scale solar -- it does not serve the residential or commercial rooftop solar market.
