Why First Solar (FSLR) Is a Strong Buy in 2026

The global solar manufacturing industry has expanded rapidly over the past decade as countries and energy providers shift toward renewable power. Solar energy, particularly utility-scale solar farms, has become one of the fastest-growing sources of electricity because of declining production costs and increasing demand for low-carbon energy. At the same time, the industry is highly competitive, with Chinese manufacturers dominating global panel production due to large-scale manufacturing capacity and lower costs. This has created significant pressure on non-Chinese producers to differentiate themselves through technology, efficiency, and domestic production. In the United States, government policies such as the Inflation Reduction Act have further accelerated solar adoption by providing tax credits and incentives for renewable energy projects and domestic manufacturing. Within this landscape, First Solar occupies a distinct position in the solar value chain as a U.S.-based manufacturer specializing in thin-film solar modules, supplying panels primarily for large utility-scale projects while benefiting from policy support aimed at strengthening domestic clean-energy production.

First Solar was founded in 1999 and has grown into one of the largest solar manufacturers headquartered in the United States, evolving from a small photovoltaic technology company into a major supplier of solar modules for large energy projects. The company’s core business centers on manufacturing advanced thin-film solar modules and supporting the development of utility-scale solar power plants, which are designed to supply electricity directly to the grid. Over time, First Solar has focused heavily on improving manufacturing efficiency and scaling production, with major manufacturing facilities located in the United States, Malaysia, and Vietnam. Its primary customers include utilities, independent power producers, and large energy developers that build large-scale solar farms. Revenue is largely driven by long-term supply agreements for solar modules used in these projects. Strategically, First Solar concentrates on the utility-scale solar market rather than residential or rooftop systems, positioning the company as a key supplier for large renewable energy installations that support the global transition toward lower-carbon electricity generation.

First Solar’s main technological advantage is its use of cadmium telluride (CdTe) thin-film solar cells rather than the conventional crystalline silicon (c-Si) technology used by most global solar manufacturers. In First Solar’s modules, CdTe acts as the light-absorbing semiconductor layer, allowing efficient sunlight absorption with significantly less material usage. This gives the company a structural cost advantage while maintaining competitive performance.

Compared with conventional crystalline silicon panels, CdTe modules offer stronger real-world performance characteristics. They perform better in high temperatures, humid climates, and low-light conditions, and are less susceptible to degradation issues such as microcracks. These advantages make them particularly well-suited for large utility-scale solar installations, where long-term energy output and reliability matter more than peak efficiency ratings.

From a cost perspective, First Solar benefits from a simplified and highly automated manufacturing process that reduces production time and input intensity. Critically, CdTe modules do not rely on polysilicon, insulating the company from price volatility and geopolitical risks tied to the global polysilicon supply chain. This also aligns with increasing regulatory scrutiny around sourcing practices.

Over the long term, these technological and supply-chain advantages support stronger margins and pricing power. First Solar’s ability to deliver consistent energy output, lower lifecycle costs, and ESG-aligned products positions it as a premium provider in a market often driven by commoditized pricing.

First Solar has demonstrated strong and consistent revenue growth, driven by rising global demand for utility-scale solar energy. Over recent years, revenue has scaled alongside production capacity expansions and an increasing volume of long-term supply agreements with major energy developers.

One of the company’s most important demand indicators is its contracted backlog, which extends several years into the future. This backlog provides high revenue visibility and reduces short-term volatility, as a large portion of future production is already committed under fixed agreements. These contracts are primarily with utilities and large-scale developers, reflecting the company’s focus on grid-level energy generation.

Demand trends remain particularly strong in the United States, where policy incentives and electrification efforts are accelerating solar adoption. At the same time, international markets such as Europe and India are contributing to growth as governments pursue energy security and decarbonization goals.

Looking ahead, solar demand is expected to grow under multiple scenarios. In a base case, steady policy support and cost declines drive continued expansion. In a bullish scenario, increased electrification, AI-driven power demand, and faster decarbonization targets significantly accelerate solar deployment. Across these scenarios, First Solar is well positioned to capture demand due to its scale, backlog, and differentiated technology.

First Solar remains one of the more profitable large-scale solar manufacturers, though its margins have come off unusually high 2024 levels. In full-year 2025, the company generated $5.2 billion in net sales, $2.12 billion in gross profit, and $1.60 billion in operating income, implying a gross margin of about 40.8% and an operating margin of about 30.7%. While slightly lower than 2024 levels, these margins remain exceptionally strong relative to industry peers.

A key driver of this profitability is manufacturing scale combined with a differentiated cost structure. First Solar’s expansion to over 25 GW of expected capacity by 2026 enables economies of scale, while its CdTe technology reduces reliance on expensive inputs like polysilicon. This allows the company to maintain positive margins even as competitors face pricing pressure.

Compared with peers such as JinkoSolar and Canadian Solar, which have reported significantly lower margins or even operating losses, First Solar stands out for its consistent profitability. This reflects both technological differentiation and strategic positioning in the utility-scale market.

Looking forward, profitability is expected to remain strong, though somewhat dependent on execution. Costs related to ramping new factories and scaling production may temporarily weigh on margins, but long-term efficiency gains and sustained demand should support continued margin leadership.

Government policy plays a critical role in First Solar’s growth trajectory, particularly in the United States. The Inflation Reduction Act (IRA) has significantly boosted domestic solar manufacturing by offering tax credits tied to U.S.-based production. First Solar is one of the primary beneficiaries of these incentives due to its large domestic manufacturing footprint.

In addition to direct subsidies, trade policies and tariffs on imported solar panels have helped level the competitive landscape against low-cost foreign producers. These measures provide additional protection for domestic manufacturers and encourage investment in U.S.-based capacity.

However, reliance on policy support also introduces risk. Changes in political leadership or regulatory priorities could impact incentives, trade protections, or renewable energy funding. As a result, while policy acts as a major tailwind, it also represents a key variable in the company’s long-term outlook.

First Solar integrates ESG directly into its core business strategy through its “Responsible Solar” framework, which emphasizes environmental stewardship, responsible supply chains, labor and human-rights protections, and strong corporate governance. The company supports this positioning with extensive sustainability reporting, including annual sustainability and corporate responsibility reports, CDP climate disclosures, and publicly available policy documents that improve transparency for investors and stakeholders. A key component of First Solar’s sustainability narrative is its cadmium telluride (CdTe) thin-film solar technology, which has a significantly lower lifecycle carbon footprint and faster energy payback time compared with many conventional crystalline silicon panels. The company also promotes circular manufacturing through a module recycling program designed to recover the majority of semiconductor and glass materials at the end of a panel’s life. Together, these practices strengthen First Solar’s ESG profile and contribute to generally positive perceptions among investors focused on climate solutions, sustainable manufacturing, and responsible supply-chain management.

First Solar differentiates itself through a strong focus on environmental sustainability, particularly in how its products are manufactured and recycled. Solar manufacturing can be resource-intensive, but First Solar’s CdTe technology reduces carbon emissions, water usage, and overall environmental impact compared with traditional silicon-based production.

A key pillar of this strategy is the company’s advanced recycling program. First Solar was one of the first solar manufacturers to implement a large-scale, global recycling system for its modules. At the end of a panel’s life, up to 90% of materials—including glass and semiconductor components—can be recovered and reused in new products.

This circular economy approach not only reduces waste but also lowers long-term material costs and environmental liabilities. Compared with many competitors, whose recycling capabilities remain limited or underdeveloped, First Solar’s established infrastructure provides both an ESG advantage and a potential long-term cost benefit.

First Solar’s supply chain strategy is built around resilience, transparency, and reduced geopolitical risk. Unlike many solar manufacturers that depend heavily on polysilicon sourced from concentrated regions, First Solar’s CdTe technology allows it to avoid this dependency altogether.

The company emphasizes ethical sourcing practices, including strict supplier standards and audits to ensure compliance with labor and human-rights guidelines. This is particularly important in an industry that has faced scrutiny over forced labor risks in certain regions.

In addition, First Solar has diversified its manufacturing footprint across multiple countries, reducing exposure to regional disruptions and improving supply chain stability. While risks related to raw material sourcing—such as mining impacts for cadmium and tellurium—still exist, the company’s proactive ESG policies help mitigate reputational and operational challenges.

First Solar operates in a highly competitive global market alongside major players such as LONGi Green Energy, JinkoSolar, and Canadian Solar. While many competitors focus on crystalline silicon technology and compete aggressively on price, First Solar differentiates itself through its CdTe platform and focus on utility-scale projects.

This differentiation allows the company to compete less on commoditized pricing and more on total system value, including energy yield, reliability, and lifecycle costs. As a result, First Solar has established a strong position in the utility-scale segment, particularly in the U.S. market.

Market share trends indicate that while Chinese manufacturers dominate global shipments, First Solar maintains a leading position among non-Chinese producers and continues to gain traction in regions prioritizing domestic supply chains and energy security.

First Solar’s stock (FSLR) has experienced strong performance in recent years, driven by improving fundamentals, favorable policy support, and growing investor interest in clean energy. The company typically trades at a premium valuation relative to peers, reflecting its higher margins, differentiated technology, and more stable earnings profile.

Key valuation metrics such as price-to-earnings (P/E) and EV/EBITDA ratios suggest that investors are pricing in continued growth and margin strength. Analyst sentiment is generally positive, with many highlighting First Solar’s backlog visibility, domestic manufacturing advantage, and exposure to long-term energy transition trends.

Institutional ownership remains high, indicating strong confidence from large investors. However, valuation levels also imply that execution risks and policy changes could lead to volatility if expectations are not met.

First Solar presents a compelling long-term investment case driven by several key upside factors. Continued growth in global solar demand, supported by decarbonization efforts and electrification trends, provides a strong macro tailwind. U.S. policy incentives, particularly under the Inflation Reduction Act, further enhance the company’s competitive positioning and profitability. Additionally, ongoing manufacturing expansion increases capacity and revenue potential.

However, the investment is not without risks. Technological competition from improving silicon-based panels could narrow First Solar’s differentiation over time. Policy dependence introduces uncertainty, particularly if government support weakens. Commodity price fluctuations and execution risks related to scaling production also remain important considerations.

From an ESG perspective, First Solar is well positioned to benefit from increasing investor focus on sustainable and responsible businesses. Its strong environmental profile and transparent supply chain practices add to its long-term appeal.

Overall, First Solar stands out as a high-quality player in the global solar industry. Its combination of technological differentiation, strong margins, policy support, and long-term demand visibility supports a bullish investment thesis, making it a strong candidate for investors seeking exposure to the energy transition.
