FSLR vs JKS: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: FSLR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. FSLR and JKS share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined FSLR and JKS exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

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.

JinkoSolar (JKS) is one of the world's largest solar photovoltaic module manufacturers, headquartered in Shanghai, China, and listed in the United States as an American Depositary Receipt (ADR) on the NYSE, where each ADR represents four ordinary shares. The company designs, makes, and sells solar modules, cells, and wafers, and has expanded into energy-storage systems, mainly through its majority-owned (about 54%) Shanghai-listed operating subsidiary Jinko Solar Co., Ltd. It shipped roughly 86 gigawatts of modules in 2025, holding its position as the top module supplier by volume for the seventh straight year. That scale has not translated into steady profits. The global solar industry is in a severe oversupply, and module prices have fallen far faster than costs, compressing margins across the sector. JinkoSolar reported total revenue of about US$9.4-9.6 billion in 2025, down roughly 20% year over year, with gross margin collapsing to about 2.2% and a full-year net loss. The slide continued in 2026: second-quarter revenue was about US$1.82 billion, down about 31% year over year, with a net loss near US$103 million, though the loss per ADR of $0.49 was narrower than the $0.70 analysts expected. On October 16, 2026 the operating subsidiary estimated a nine-month 2026 net loss of RMB 2.98-3.58 billion under PRC accounting.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• FSLR drivers: Domestic manufacturing incentives; Differentiated thin-film technology.
• JKS drivers: Scale leadership in a growing end market; Technology and storage expansion.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: First Solar's fortunes are closely tied to policy, particularly US clean energy manufacturing incentives, which could change with political shifts. For JKS, the overriding risk is a severe, industry-wide solar oversupply that has pushed module prices below the production cost of many manufacturers, crushing margins: JinkoSolar's 2025 gross margin fell to roughly 2.2% from 10.9% a year earlier, its trailing gross margin is under 5%, and it has posted net losses in each of the last four quarters, with the operating subsidiary estimating a nine-month 2026 loss of RMB 2.98-3.58 billion.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick FSLR if you believe its drivers more; JKS if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the FSLR and JKS guides.

FSLR. First Solar is valued as a profitable, policy-advantaged solar manufacturer with substantial contracted backlog, and in October 2026 that valuation is low by its own standards: about 11 times trailing earnings, about 7.5 times forward estimates and about 7.4 times EBITDA after a roughly 36% fall in 2026. Investors are weighing strong margins and incentive support against uneven revenue, policy and trade risk, and higher rates. The October 29, 2026 report (consensus EPS near $4.70) will update the picture.

JKS. JinkoSolar's economics are dominated by the price of solar modules, which the company does not control and which fell faster than its costs during the oversupply. With four straight loss-making quarters a trailing P/E is not meaningful, and the ADR at about 0.2 times book trades on expectations for a module-pricing recovery, industry capacity cuts, the value of its tech stakes, and the RMB. Data providers list a dividend rate of about $1.50 per ADR (an ~18% yield at the October 2026 price, far above earnings), which should not be read as a reliable recurring payout. Third-quarter results are expected around mid-November 2026; all figures are approximate.

Headline figures (approximate, October 2026): FSLR shows revenue (ttm) ~$5.4 billion (Q2 2026 down ~4% year over year), margins (ttm) ~44% gross, ~43% operating, ~32% net, net income (ttm) ~$1.75 billion, q2 2026 eps ~$3.92 vs ~$2.88 expected; JKS shows q2 2026 revenue ~US$1.82 billion, down about 31% year over year, q2 2026 result net loss ~US$103 million; loss of $0.49 per ADR vs. ~$0.70 expected, gross / operating margin (ttm) ~4.8% / ~-11.5%, revenue (fy2025) ~US$9.4-9.6 billion, down roughly 20%; ~86 GW shipped.

FSLR and JKS are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined FSLR and JKS exposure against your real portfolio. It is not an investment adviser.
