Written summary
Exiom is a Spanish manufacturer founded in 2019 and headquartered in Asturias, with roughly 100 employees and a production capacity of 0.5 GW. The company does not hold Tier 1 bankable status, which is a key distinction from Jinko Solar - a Chinese industry giant founded in 2006, listed on the NYSE, employing over 33,800 people, and operating at a scale of 130 GW annual production capacity. Jinko Solar is one of the most widely recognised names in global PV manufacturing and has maintained Tier 1 status consistently, giving financiers and developers strong confidence in long-term product warranties and corporate continuity. Exiom, by contrast, is a smaller regional player currently building a 500 MW module factory in Langreo, Spain in partnership with Iberdrola - a project that signals strategic ambitions in European domestic manufacturing.
Technologically, Exiom's current portfolio is built primarily around PERC cell technology (72% of models), with a maximum module efficiency of 23.4% and an average of 19.6%. A notable feature is its high share of bifacial panels (72%), making the lineup suitable for flat-roof commercial installs, ground-mount systems, and agri-PV applications that can benefit from albedo gain. Jinko Solar leads on cell technology, with TOPCon as its dominant offering (39% of models), reaching a maximum efficiency of 24.8% and an average of 22.0%. Jinko's better temperature coefficient (-0.308%/°C vs. -0.347%/°C for Exiom) delivers lower thermal losses in warm climates, and its portfolio of 545 models spanning up to 735 Wp covers residential rooftop installs, large commercial C&I projects, and utility-scale ground-mount deployments globally.
For international buyers choosing between the two, Jinko Solar is the lower-risk, higher-performance option for most project types - its Tier 1 status simplifies project financing and insurance, while its broad portfolio and proven global supply chain reduce procurement risk. Exiom is a credible alternative for buyers who prioritise European-made modules for ESG or supply-chain compliance reasons, or for installers seeking bifacial panels in the mid-power range, provided they are comfortable operating outside a Tier 1 framework.
