The company claims annual module shipments in the range of 4 GW to 8 GW, though independent confirmation of the upper figure is limited. No BloombergNEF Tier 1 designation for Q-SUN has been confirmed by publicly available sources at the time of writing. AIKO Solar, also a Chinese manufacturer, is a more recent entrant that has grown rapidly: it secured BloombergNEF Tier 1 status in Q3 2024 and reports an annual production capacity of around 20 GW. AIKO received the 2025 SolarQuotes Installers' Choice Award and has held the top position on TaiyangNews' monthly high-efficiency module ranking for over 34 consecutive months. On institutional footprint, AIKO clearly holds the stronger position. Q-SUN Solar's catalog centers on N-type TOPCon technology - notably the Mercury Series with outputs spanning roughly 400 W to over 580 W - and the full-black Onyx Series, which targets design-conscious residential rooftops. Certified to ISO 9001, ISO 14001, and ISO 45001 and TUV-approved, Q-SUN is well positioned for commercial and budget-utility segments where cost competitiveness outweighs headline efficiency. AIKO differentiates through its proprietary ABC (All Back Contact) cell architecture, which relocates all electrical contacts to the rear of the cell to eliminate front-side shading losses. The result is class-leading efficiency - AIKO reported a mass-produced module efficiency of 24.8% in late 2025 - along with superior low-light and high-temperature performance. Its Neostar series targets premium residential and commercial rooftops where maximizing output per square meter justifies a price premium. For buyers seeking the best available efficiency in 2025 and willing to pay for it, AIKO is the clearer choice, backed by verifiable Tier 1 bankability and consistent independent benchmarking. Q-SUN is a credible mid-market alternative for buyers prioritizing cost and supply flexibility, particularly in commercial or utility contexts, but lacks comparable independent recognition at this stage. \---LINKS--- \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://taiyangnews.info/technology/aiko-solar-abc-module-power-efficiency \| AIKO ABC module efficiency deep-dive - TaiyangNews \| article \- https://solarbytes.info/aiko-secures-global-bnef-tier1-solar-maker-status-q3-2024/ \| AIKO secures BNEF Tier 1 status Q3 2024 - SolarBytes \| article \- https://www.enfsolar.com/q-sun-solar \| Q-SUN Solar manufacturer profile - ENF Solar \| article \- https://www.youtube.com/watch?v=rdkVNV5djeA \| NEW AIKO Neostar 3 Review - Are Aiko Solar Panels the BEST in 2025? \| video Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
