First Solar is a solar technology company that manufactures advanced thin-film modules for large-scale power plants. It generated $5.22 billion in revenue in 2025, growing 24% over the previous year. The company is currently sitting on a massive 47.9 GW contracted sales backlog that stretches into the end of the decade, providing a level of visibility that is rare in the volatile energy sector.
The investment thesis on First Solar is that its proprietary thin-film technology and US-based manufacturing footprint provide a massive cost and policy advantage that Chinese rivals cannot easily replicate. More specifically, four things need to be true:
We lean positive on First Solar because it is the primary beneficiary of a US policy environment that heavily rewards domestic solar production while taxing imports. This setup provides a protected profit pool that the company is using to fund a massive expansion of its manufacturing capacity.
First Solar’s stock has soared over the last five years as the company became a powerhouse in the clean energy market. The price jumped because their unique American-made solar panels are in huge demand, giving the business a full schedule of guaranteed sales through the end of the decade that keeps them ahead of foreign rivals.
What does it do?
First Solar is a growth business that earns money by designing, manufacturing, and selling advanced thin-film solar modules to large-scale power developers. Unlike most competitors who use silicon, First Solar uses cadmium telluride technology which performs better in hot and humid conditions. The company sells these modules in massive quantities for utility-scale projects, where thousands of panels are used to build a single power plant. Revenue flows through fixed-price contracts, and the company is currently building out its manufacturing base to deliver on a multi-year queue of orders.
Where does revenue come from?
The vast majority of revenue comes from selling solar modules to third-party developers of large power plants. This includes both the sale of the physical panels and occasional licensing of technology. While the company operates globally, the United States is its largest and most profitable market due to high demand for domestic products.
Revenue Breakdown
Revenue by Geography
Who are its customers?
First Solar serves a concentrated group of global power plant developers and independent power producers. As of March 31, 2026, the company reported a contracted sales backlog of 47.9 GW, which represents several years of future production. While it does not disclose a total number of active customers in the same way a software company does, its customer base includes major energy firms like NextEra Energy and global project developers in markets like India and Australia. In the first quarter of 2026 alone, it delivered modules for over 3.4 GW of solar capacity.
What gives it staying power?
First Solar is protected by its proprietary thin-film technology and its fully integrated US manufacturing process. It owns hundreds of patents on cadmium telluride production, a process that is significantly different from the silicon-based manufacturing used by Chinese competitors. This technical barrier is reinforced by its ability to avoid the tariffs and supply chain risks that plague its rivals.
Where is it headed?
The company is making a massive strategic bet on expanding its US manufacturing capacity to capture domestic tax incentives. Management is currently building new factories in Alabama and Louisiana, which will significantly increase its total production volume. If successful, this expansion will allow First Solar to meet its massive backlog while collecting billions in government tax credits for every component it produces on American soil.
First Solar is seeing a sharp acceleration in revenue and earnings as it ramps up delivery on its multi-year backlog. Total revenue grew 24% to $5.22 billion in 2025, while net income surged over 80% to $1.53 billion. This growth is driven by both higher sales volumes and the benefits of manufacturing scale.
Cash generation is becoming a major strength as the company moves past a heavy period of factory construction. Free cash flow turned positive in 2025, reaching $1.19 billion after several years of negative results. This shift proves that the business can self-fund its growth while still maintaining a massive cash cushion.
The balance sheet is exceptionally strong with a net cash position of $2.0 billion and almost no long-term debt. This $2.0 billion cushion gives First Solar the ability to fund its factory expansions without relying on expensive outside financing. For a manufacturing business, this level of liquidity provides a massive safety margin during economic downturns.
First Solar is a financially dominant manufacturer that is effectively using government incentives to fund a massive expansion of its profit-making capacity.
The company is successfully translating its 47.9 GW backlog into record profits through high-margin US production. The combination of rising delivery volumes and significant tax credits from the Inflation Reduction Act is driving net margins above 30%.
A potential change in US trade or tax policy could sharply reduce the profitability of future module sales. If the Section 45X manufacturing credits are significantly reduced or eliminated, the company's net income would fall by hundreds of millions of dollars.
The utility-scale solar market is approximately $200 billion today and is on track to exceed $350 billion by 2029 as the world shifts toward renewable energy. This is a high-growth industry where pricing power is structural for companies that can provide reliable, domestic supply chains. First Solar is the dominant US-based player in this market, holding a unique position as the only major manufacturer that does not rely on Chinese silicon supply chains. This gives it a massive runway as US utilities prioritize energy security and domestic content.
The solar industry is generally characterized by intense price competition and a race to the bottom on panel efficiency. However, the US market is currently a "protected island" where domestic content rules create high barriers to entry for foreign firms. This dynamic allows US-based manufacturers to maintain higher margins than their global peers who must compete purely on manufacturing costs.
Hanwha Q Cells is the most direct threat because it is the only other major firm with a massive US manufacturing footprint that can match First Solar's policy advantages. Canadian Solar and JinkoSolar are global giants that are now trying to build US factories to bypass tariffs. The most dangerous threat is Hanwha Q Cells, which is spending billions to build a fully integrated US supply chain that could eventually challenge First Solar's pricing power.
First Solar is holding its ground and gaining high-quality share by signing multi-year contracts that lock in its production for the next half-decade. The 47.9 GW backlog is the clearest evidence that First Solar is winning the race for long-term supply security.
First Solar's primary protection is a massive cost advantage driven by its proprietary thin-film technology and government tax credits. Because it uses cadmium telluride instead of silicon, it has fewer manufacturing steps and is eligible for unique subsidies. The company's 30.7% net margin, which is far higher than most hardware manufacturers, proves that this cost advantage is real and durable.
These numbers show that First Solar is not just a typical manufacturer; it is a technology business with high switching costs. Once a utility signs a 5-year supply agreement, First Solar is locked into that project's economics. The combination of a 15.4% ROIC and a backlog that is nearly ten times annual revenue proves that this moat is built on more than just a good business cycle.
The forward-looking verdict is that this moat is widening as First Solar builds more US capacity and integrates its supply chain further. Its independence from Chinese silicon is becoming a more valuable asset every year as trade tensions rise.

Capital Allocation Track Record
Mark R. Widmar has led First Solar with a steady hand, focusing on a "Series 7" technology pivot and a massive US manufacturing expansion that is now paying off. He has shown exceptional strategic judgment by positioning the company as the "non-silicon" alternative just as supply chain and forced-labor concerns became central to the industry. The management team has been disciplined in not over-extending the balance sheet, keeping debt extremely low while funding a multi-billion dollar expansion program through operating cash flow and tax incentives.
The primary governance risk is the company's heavy dependence on Widmar's leadership during this critical construction and ramp-up phase. While First Solar has a deep bench of technical talent, the strategic relationship-building required to manage US trade policy and large utility contracts is concentrated in the top tier of executives. There is currently no dual-class structure or major founder control, which ensures the board remains independent and accountable to shareholders.
We expect revenue to grow from $5.1B in FY2026 to $8.6B in FY2031 (~11% CAGR), with EPS growing from $17.70 to $45.69 (~21% CAGR). Revenue grows as the company ramps up new manufacturing facilities in Alabama and Louisiana to meet the massive backlog of solar module orders. Profit margins increase because the company receives significant government tax credits for every solar component they manufacture in the United States. EPS grows faster than revenue because the fixed costs of running factories are spread across more units while tax incentives provide a pure profit boost. Operating margin expected to reach ~35% by FY2031.
Manufacturing expansion triples output to meet the massive backlog. Ramping factories in Alabama and Louisiana will allow First Solar to deliver on its 47.9 GW queue, dramatically lifting revenue.
Next-generation module efficiency widens the lead over silicon rivals. Continuous R&D into tandem modules could push panel efficiency higher, allowing First Solar to charge a premium for better performance.
International expansion in India captures a massive new growth market. The new facility in India provides a growth engine outside the US that is also protected by domestic content incentives.
Repeal or reduction of Section 45X tax credits guts profitability. If US political shifts lead to a reduction in manufacturing subsidies, First Solar's earnings would decline sharply as its cost advantage shrinks.
Major backlog cancellations if power plant projects face permitting delays. If high interest rates or grid-connection bottlenecks slow down project construction, developers may delay or cancel their module orders.
Rapid improvement in silicon efficiency makes thin-film less competitive. If traditional panels become significantly cheaper or more efficient, First Solar may lose its pricing power in the utility market.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach based on next year's earnings (FY+1). It fits First Solar because the company has a highly predictable revenue stream via its contracted backlog and clear visibility into its margin profile thanks to fixed US manufacturing tax credits. This makes earnings the cleanest and most reliable signal of value for the business today.
Applying a 20x multiple to our FY2026 EPS estimate of $17.70 results in a fair value of $354 per share. A 20x multiple sits at the higher end of the clean energy peer group (Enphase at 22x, NextEra Energy at 18x, SolarEdge at 12x), which is justified by First Solar’s "Wide Moat" rating and its unique insulation from Chinese trade tariffs. We used the FY2026 EPS of $17.70 directly from the deterministic projection to ensure consistency with the broader report’s fundamental outlook.
A 5-year Discounted Cash Flow cross-check produces a fair value of $390 — within 10% of our $354 Forward P/E answer, confirming the result. This cross-check uses a 10% discount rate and the projected ramp in free cash flow as the new Series 7 facilities reach scale. While the DCF suggests even higher long-term upside ($625 in the ultra-bull case), we prefer the $354 target as a more grounded 12-to-18 month valuation that reflects current market sentiment toward manufacturing multiples.
We're assuming First Solar maintains a dominant 90%+ share of the US utility-scale thin-film market through 2028. This is supported by the company’s $2.4B net cash position and its vertically integrated manufacturing process, which avoids the volatile polysilicon supply chain that impacts Asian competitors like JinkoSolar.
We're assuming the Section 45X tax credits remain fully intact through the 2030 sunset provision. Management has guided for a significant portion of FY2026 operating income to be derived from these credits, and the current political environment remains incentivized to protect domestic energy supply chains against overseas dumping.
We're assuming Series 7 module production ramps to full capacity of 17.7 GW by 2027. The current backlog and the expansion of the Alabama and Louisiana facilities suggest that demand is not the bottleneck; instead, the fair value relies on the company's ability to hit its stated manufacturing yield and cost-per-watt targets.
The biggest risk is a shift in US trade and energy policy that reduces the value or duration of the Section 45X manufacturing tax credits. This would erode First Solar's primary margin advantage over lower-cost silicon competitors, potentially compressing the forward multiple from 20x to 12x and knocking roughly $142 off the per-share fair value. Watch for "domestic content" eligibility changes in upcoming IRS guidance as the early signal.
Bear case ($212): Federal manufacturing tax credits (Section 45X) are repealed or significantly diluted in a legislative shift; or Series 7 module production yields fall below 85% due to technical bottlenecks at the new Alabama or Louisiana facilities.
Bull case ($485): US domestic content bonuses for solar projects are increased, allowing for an additional $0.05/watt pricing premium; or Global thin-film adoption accelerates in India, doubling the non-US revenue contribution to 8% by 2028.

The market is leaning bullish because First Solar holds a massive backlog that guarantees revenue through the end of the decade. The company uses unique thin-film technology made in the United States, giving it a stable supply chain and protection from cheaper overseas competition that other energy providers cannot match.
Skeptics think that the actual profit margins may crumble as the company attempts to clear its nearly 48 gigawatt backlog. They worry that manufacturing these specific thin-film modules at such a massive scale will lead to unexpected technical or supply costs that shrink earnings faster than analysts currently anticipate.
