The company earned BloombergNEF Tier 1 bankability status in Q3 2024 and has scaled quickly, with production capacity reported at roughly 20 GW in 2025 and rising toward the mid-30 GW range by early 2026, placing it among the larger Tier 1 module makers by volume. CEEG, headquartered in Nanjing and founded in 1990, is a long-established Chinese electrical equipment conglomerate whose PV arm produces modules under the CEEG and Quasar brands through its China Sunergy subsidiary, with panels certified to IEC 61215, IEC 61730 and UL 1703 standards. Available figures put CEEG's dedicated solar production capacity at a comparatively modest 600 MW across four factories, a much smaller scale than AIKO's, and public sourcing did not confirm current BloombergNEF Tier 1 status for CEEG, suggesting a weaker institutional and bankability footprint than AIKO's. AIKO's product lineup, including its Infinite series, centers on high-efficiency ABC modules reaching around 22 to over 24 percent efficiency, positioned for premium residential rooftops as well as commercial and industrial installations, with 2025 launches pushing toward 500 W, 25 percent-efficiency C&I modules and silver-free copper metallization for improved durability. CEEG's offering leans toward conventional crystalline-silicon modules and broader electrical equipment solutions (including transformers and grid gear), reflecting its identity as a diversified power-equipment group rather than a specialized high-efficiency PV innovator; its panels are generally positioned for standard residential and commercial projects across its established European and Chinese customer base rather than cutting-edge efficiency niches. For a typical buyer in 2025, AIKO is the stronger default choice: it holds confirmed Tier 1 bankability, larger and rapidly growing manufacturing scale, and clear technological differentiation through ABC back-contact cells offering higher efficiency and better aesthetics. CEEG remains a legitimate, long-tenured Chinese manufacturer with solid certifications and an established European distribution network, making it a reasonable option for conventional, budget-conscious projects, but it does not match AIKO's institutional footprint or technology leadership. \---LINKS--- \- https://www.pv-magazine.com/2025/03/12/aiko-launches-500-w-ci-back-contact-solar-module-with-25-efficiency/ \| Aiko launches 500 W C&I back-contact solar module, 25% efficiency \| article \- https://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/ \| AIKO achieves BloombergNEF Tier 1 status \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar Panels Review \| review \- https://www.enfsolar.com/ceeg \| China Electric Equipment Group (CEEG) profile \| article \- https://greenworldinvestor.com/ceeg-sst-solar-review-of-ceeg-solar-monocrystalline-modules-180250w-pricesspecifications-and-comparision/ \| CEEG SST Solar module review and specifications \| review Written by claude-sonnet-5 from the figures above. ## Other comparisons - [AIKO vs A.B.
