## Summary

AIKO is a Chinese solar manufacturer headquartered in Guangzhou, founded in 2009, that has grown into one of the most closely watched high-efficiency producers in the global market. The company achieved BloombergNEF Tier 1 status as of Q3 2024 and reported annual ABC module shipments of 14.71 GW in 2025, representing 132% year-on-year growth - a scale that places it firmly among the global top tier. SoliTek, by contrast, is a Lithuanian manufacturer founded in 2009 under the name Baltic Solar Solutions and relaunched under the SoliTek brand in 2014; it is part of the privately owned BOD Group and operates at approximately 250 MW of annual capacity, making it the largest solar panel producer in Northern Europe but a considerably smaller player globally. SoliTek does not appear on the BloombergNEF Tier 1 list, and AIKO holds the stronger institutional footprint by a wide margin.

AIKO's lineup is built exclusively around its proprietary N-type ABC (All Back Contact) technology, which removes front-surface busbars to maximize active cell area and achieve mass-produced module efficiencies above 24.8%. The range spans premium residential rooftops, commercial and industrial installations, ground-mount utility projects, and floating PV, making AIKO a versatile option for virtually any application where high efficiency justifies a higher upfront cost. SoliTek focuses on glass-glass modules with efficiencies reaching up to 22.93%, emphasizing durability, aesthetics, and sustainability credentials: the company holds a Cradle to Cradle GOLD certification and manufactures using 100% renewable energy. Its Solid Solrif BIPV product targets architecturally sensitive residential installations, and its Blackstar bifacial range suits buyers who prioritize low environmental impact and a 30-year performance guarantee over raw watt-per-square-meter output.

For most buyers in 2025, AIKO is the stronger default when maximum efficiency and bankable scale are the priorities - especially for space-constrained rooftops or large installations requiring financeable supply chains. SoliTek makes the more compelling case for European buyers who specifically require locally manufactured, sustainability-certified modules or are specifying a BIPV roof integration, niches where its EU origin and Cradle to Cradle pedigree carry genuine commercial value.
