Written summary
AIKO is a Chinese manufacturer founded in 2009 and headquartered in Shanghai, with multiple gigafactories spread across China. The company achieved BloombergNEF Tier 1 status in Q3 2024, placing it among the small fraction of global suppliers to meet that bankability threshold, and its reported annual nameplate capacity surpassed 20 GW by early 2025. Sirius PV is the module brand of Elin Energy, a Turkish group active in solar manufacturing since 1981; Sirius PV was formed as a distinct brand in 2021 and operates approximately 3.5 GW per year of capacity across three factories in Turkey, alongside a newer US facility in Waller County, Texas, that opened in 2024 with an initial 1 GW target. Unlike AIKO, Sirius PV has not yet appeared on the BloombergNEF Tier 1 list, and PV ModuleTech's bankability ratings placed its parent Elin in the lower CCC tier as of mid-2024, giving AIKO a substantially stronger institutional footprint at present.
AIKO's lineup is built around its proprietary ABC (All Back Contact) cell architecture, which removes front-side grid lines and drove mass-produced module efficiencies to a reported world record of 24.4% in mid-2025. That technology positions AIKO squarely at the premium end of the residential rooftop and high-value commercial segment, supported by a 30-year performance warranty with a low 0.35% annual degradation ceiling. Sirius PV initially shipped PERC-technology modules from its Texas plant, with a transition to TOPCon underway from mid-2024 onward; its Turkish lines already produce TOPCon and glass-to-glass bifacial modules targeting residential, commercial, and utility-scale buyers. The US-assembled Sirius PV panels can qualify project developers for the IRA domestic content bonus credit, a concrete financial advantage not available with imported AIKO product.
For most buyers outside the United States in 2025, AIKO is the stronger default - its Tier 1 bankability, record-setting efficiency, and tight degradation warranty are hard to match at a comparable price point. For US developers who need domestic content qualification under the IRA, Sirius PV offers a credible alternative, though buyers and project lenders should weigh its more limited bankability track record accordingly.
