## Summary

JA Solar, founded in 2005 and headquartered in China, is one of the world's largest solar panel manufacturers, listed on the Shenzhen Stock Exchange (SZSE) with over 37,000 employees and a production capacity exceeding 100 GW per year. The company holds Tier 1 bankable status from S&P Global, ranked second globally in module shipments in 2025, and has accumulated nearly 300 GW in cumulative global deliveries. Its portfolio spans 524 panel models with peak power reaching 740 Wp and maximum efficiency of 24.4%. Lina Energy, by contrast, was founded in 2017 in the United Kingdom and operates as a small-scale manufacturer with just 28 employees and a catalogue of 37 panels. It carries no Tier 1 or equivalent bankability rating, which meaningfully limits its suitability for externally financed or insured projects.

JA Solar's portfolio is built predominantly on PERC cell technology (52.1% of its range), with a growing TOPCon offering that pushes efficiency up to 24.4% and average panel output to 441.7 Wp. A temperature coefficient of -0.323%/°C per degree Celsius positions JA Solar modules well for utility-scale ground-mount projects, large commercial and industrial (C&I) installations, and residential rooftop systems where long-term supply chain reliability is a priority. Bifacial panels account for 44.3% of the portfolio, offering strong options for dual-gain ground-mounted configurations. Lina Energy's 37-panel range tops out at 550 Wp and 22.37% efficiency, with an average output of 401.9 Wp and a slightly less favorable temperature coefficient of -0.352%/°C. The dominant cell technology for 35.1% of its catalogue is classified as unknown, which limits technical transparency for specifiers. Lina Energy's average warranty of 28.38 years is marginally longer than JA Solar's 27.85 years, though enforcing warranty claims against a 28-person company presents a practical risk over a multi-decade horizon.

For international buyers choosing between the two, JA Solar is the clear selection for any project requiring bankability, high-volume supply, or independently verified reliability - backed by repeated Top Performer recognition in PVEL testing. Lina Energy may suit buyers in markets that formally prefer European-sourced equipment or who require small, custom-specification orders, but its limited scale and absence of third-party reliability ratings make it a higher-risk option wherever long-term warranty support is a critical procurement criterion.
