As the global energy transition accelerates into the second half of the decade, few companies have managed to maintain as strategic a “fortress” position as First Solar, Inc. (NASDAQ: FSLR). Once a niche player in a market dominated by silicon-based semiconductors, the Tempe, Arizona-headquartered firm has emerged as the definitive champion of American solar manufacturing. In early 2026, First Solar finds itself at the intersection of two of the decade’s most powerful secular trends: the re-industrialization of the United States and the voracious electricity appetite of Artificial Intelligence (AI) data centers.
While the broader solar industry has faced headwinds from high interest rates and global oversupply, First Solar has insulated itself through a unique thin-film technology stack and a multi-year backlog that stretches toward the end of the decade. At PredictStreet, our AI-driven analysis indicates that the company’s recent manufacturing expansions in the American South have fundamentally altered its margin profile, making it less of a commodity manufacturer and more of a high-value infrastructure provider.
The First Solar story is one of American ingenuity and patient capital. It began in 1990 as Solar Cells, Inc. (SCI), founded by Harold McMaster, a legendary inventor known as the “Glass Genius” of Toledo, Ohio. McMaster’s breakthrough was the use of Cadmium Telluride (CdTe) for thin-film solar cells, an alternative to the traditional crystalline silicon (c-Si) path. His vision was to manufacture solar panels as efficiently and continuously as glass sheets on a float line.
However, the transition from lab to commercial scale was fraught with financial peril. In 1999, the company was recapitalized and rebranded as First Solar, LLC, following an acquisition by True North Partners—a venture capital firm funded by John Walton, son of Walmart founder Sam Walton. The Walton family’s involvement provided the long-term capital necessary to survive the “Valley of Death” in hardware innovation.
Since its 2006 IPO, the company has undergone several major transformations. The most significant occurred in 2016 under current CEO Mark Widmar, when the company made the bold decision to bypass its “Series 5” module and move directly to the “Series 6” large-format module. This pivot, combined with the exit from its engineering, procurement, and construction (EPC) business to focus purely on manufacturing, set the stage for the explosive growth seen in the 2020s.
First Solar operates a vertically integrated manufacturing model that is unique among the world’s top solar companies. While rivals like JinkoSolar or Canadian Solar rely on a complex global supply chain for polysilicon, wafers, and cells, First Solar’s CdTe process converts raw materials into a finished module in a single, continuous automated line in under four hours.
The company generates revenue almost exclusively from the sale of solar modules to utility-scale project developers and independent power producers.
First Solar’s customer base is increasingly dominated by large tech conglomerates (Google, Microsoft, Meta) looking to power their data centers with 100% renewable energy, as well as traditional utilities. Geographically, the U.S. remains its primary market, though it maintains a significant manufacturing and sales presence in India and Southeast Asia.
Over the last decade, FSLR has evolved from a volatile, sentiment-driven stock to a cornerstone industrial asset.
PredictStreet’s latest AI-generated estimates for the fiscal year 2025 suggest a company that is hitting its operational stride.
The management team, led by CEO Mark Widmar and CFO Alex Bradley, is widely regarded by analysts as one of the most disciplined in the clean energy sector. Widmar’s strategy has been characterized by “saying no” to low-margin residential markets and “saying yes” to long-term, fixed-price contracts that provide visibility through the end of the decade.
The board’s governance has been particularly focused on navigating the complex geopolitical landscape. Their decision to stay away from Chinese silicon supply chains has been vindicated by the Uyghur Forced Labor Prevention Act (UFLPA) and subsequent trade disputes that have hamstrung many of their competitors.
The “Series 7” module is the current flagship of the First Solar fleet. Produced primarily in the new Alabama and Louisiana facilities, the Series 7 is designed specifically for the U.S. utility-scale market, offering a larger form factor and higher efficiency than previous generations.
In 2023, First Solar acquired Evolar AB, a European leader in perovskite technology. As of January 2026, the company is operating a pilot line at its R&D innovation center in Ohio, developing a Perovskite-on-CdTe tandem cell. This “tandem” approach aims to stack two different light-absorbing layers to break the efficiency ceiling of traditional modules, with commercial deployment targeted for 2027-2029.
The solar market is a tale of two technologies: Crystalline Silicon (c-Si) vs. Thin-Film (CdTe).
Three macro drivers are currently favoring First Solar:
No investment is without risk, and First Solar faces several significant hurdles:
Institutional sentiment remains robust, with roughly 98% of shares held by institutions like Vanguard and BlackRock.
Geopolitics is First Solar’s “invisible moat.” The company is the primary beneficiary of:
First Solar enters 2026 as a uniquely positioned industrial powerhouse. By decoupling itself from the Chinese silicon supply chain and leaning into the “Made in America” narrative, it has transformed from a solar module manufacturer into a critical infrastructure provider for the 21st century.
For investors, the key will be watching the execution of the Louisiana and Alabama capacity ramps and the stability of the contract backlog. While policy risks and global pricing pressures remain, First Solar’s “fortress” model provides a margin of safety rarely seen in the renewable energy space. As AI continues to drive an unprecedented need for electrons, the “Glass Genius” legacy of Harold McMaster looks more relevant than ever.
