FSLR (First Solar, Inc.): Themes, ETFs, and Basket Ideas
Last updated June 2026
Short answer
What does First Solar, Inc. do?
First Solar is one of the largest solar panel manufacturers in the United States and the leading maker of thin-film solar modules. Unlike most competitors that use crystalline silicon, First Solar uses a cadmium telluride (CdTe) thin-film technology that it developed and manufactures at scale. This gives it a differentiated cost structure, strong performance in hot and humid climates, and a supply chain largely independent of the Chinese silicon ecosystem. The company sells utility-scale solar modules primarily to large developers and power producers building solar farms, mainly in the US, India, and other markets. First Solar makes money by manufacturing and selling these modules, and its US-based production qualifies for domestic manufacturing incentives. Headquartered in Tempe, Arizona, First Solar has expanded capacity aggressively across Ohio, Alabama, Louisiana, and India. It benefits from policy support for domestic clean energy manufacturing and from buyers seeking non-Chinese solar supply.
Where is First Solar, Inc. heading?
1. Domestic manufacturing incentives.
First Solar is a major beneficiary of US policy supporting domestic clean energy manufacturing, including production tax credits for US-made solar modules. As one of the largest American panel makers, it captures meaningful incentive value that supports margins and funds capacity expansion across several US states.
2. Differentiated thin-film technology.
First Solar's cadmium telluride thin-film technology gives it a supply chain largely independent of Chinese silicon, strong performance in hot climates, and a distinct cost structure. This differentiation appeals to utility-scale buyers seeking reliable, non-Chinese supply and a hedge against polysilicon market volatility.
3. Large contracted backlog.
First Solar typically sells modules under multi-year contracts, giving it a large backlog that extends visibility well into the future. This contracted volume reduces near-term demand uncertainty and supports planning for additional manufacturing capacity and technology investment.
Risks worth tracking: First Solar's fortunes are closely tied to policy, particularly US clean energy manufacturing incentives, which could change with political shifts. Solar is a cyclical, competitive industry with persistent pricing pressure from low-cost Chinese silicon panels. Oversupply, tariffs, and trade disputes can swing economics quickly. The company also faces technology risk, since its thin-film approach must keep pace with improving silicon efficiency. Interest rates affect utility-scale project economics, and large customers can delay or cancel projects. Manufacturing ramp execution, warranty issues, and module quality concerns are additional risks for a capital-intensive business that depends on flawless large-scale production.
Earnings and valuation (approximate, early 2026)
A simple financial snapshot. These are approximations and refresh quarterly; for current figures see First Solar, Inc.'s investor relations page or your broker.
- Revenue (TTM): ~$4 to 5 billion
- Operating margin: ~high teens to mid-twenties percent
- Net income (TTM): ~$1 billion or more
- Contracted backlog: ~tens of gigawatts, multi-year
- Cash position: ~strong net cash
- Market cap: ~low tens of billions
First Solar is valued as a profitable, policy-advantaged solar manufacturer with substantial contracted backlog. Investors weigh strong current margins and incentive support against the cyclicality and pricing pressure of the broader solar industry. The valuation reflects both the durability of its domestic manufacturing position and sensitivity to policy and trade developments.
FSLR's competitors
Crystalline silicon panel makers
Competes against large Chinese silicon module manufacturers such as JinkoSolar, LONGi, and Trina Solar, which dominate global volume and compete largely on price.
US solar manufacturers
Faces growing competition from other domestic and Western panel makers expanding US capacity to capture the same manufacturing incentives.
Broader clean energy supply
Competes for utility-scale project share with alternative generation and storage providers as developers weigh solar against other clean energy options.
