South Korean solar firms rally as U.S. keeps China product bans

South Korean solar manufacturers saw their shares rise sharply on Friday after the United States signaled that its curbs on Chinese solar imports are likely to stay in place, CNBC reported. The market reaction came as analysts linked the policy stance to the upcoming summit between President Donald Trump and Chinese President Xi Jinping, where trade and technology issues are expected to dominate the agenda.

The Korean companies that benefited most include Hanwha Q Cells, LG Energy Solution’s solar arm, and a cluster of smaller panel makers listed on the KOSPI. Their stock prices jumped between 4% and 9% in intra‑day trading, outpacing the broader market. Traders said the rally reflects expectations that U.S. tariffs and anti‑dumping duties will keep Chinese‑origin panels at a price disadvantage, opening room for Korean exporters to capture market share in the United States and Europe.

U.S. restrictions on Chinese solar products, first imposed in 2024, target alleged subsidies and unfair trade practices. The measures consist of a 25% tariff on imports and a series of anti‑circular‑economy rules that require detailed supply‑chain disclosures. While the Biden administration had hinted at a possible review, the latest statements suggest a continuation of the policy, reinforcing the competitive edge for non‑Chinese producers.

South Korea has positioned itself as a key alternative supplier in the global solar market. Over the past two years, Korean firms have expanded capacity, invested in advanced cell technologies such as heterojunction and tandem designs, and secured contracts in the United States’ growing renewable‑energy pipeline. The country’s export share of solar modules to the U.S. rose from 5% in 2022 to roughly 12% in 2025, according to industry data, underscoring the strategic importance of the U.S. curbs for Korean growth.

Analysts caution that the rally could be tempered if the Trump‑Xi summit leads to a broader trade agreement that eases the restrictions. Nevertheless, the immediate market response signals confidence that Korean solar firms will continue to benefit from a policy environment that limits Chinese competition, at least in the near term.

The broader implication is a reshaping of the global solar supply chain, where geopolitical considerations increasingly dictate investment flows and pricing dynamics. As the world pushes toward aggressive clean‑energy targets, the ability of countries like South Korea to fill gaps left by Chinese producers may accelerate the diversification of solar manufacturing hubs.
