The company targets European and Middle Eastern markets and covers PERC, TOPCon, and BIPV cell technologies across a broad wattage range. No BloombergNEF Tier 1 listing or published annual production figure in GW was found for TommaTech, placing it firmly in the mid-tier or niche-brand category by institutional standards. AIKO, by contrast, is a Chinese manufacturer that achieved BloombergNEF Tier 1 status in Q3 2024, reports a production capacity of roughly 20 GW as of early 2025, and has rapidly built a recognized footprint in financed utility and residential projects globally. On institutional bankability, AIKO holds a substantially stronger position. TommaTech's product catalog covers monocrystalline PERC and TOPCon modules suited to residential rooftops, light commercial installations, and niche segments such as BIPV facades and flexible panels for marine or vehicle use - a range that suits installers who need breadth and moderate price points in European supply chains. AIKO is built around a single technology bet: N-type ABC (All Back Contact) cells, which place all contacts on the rear of the cell to maximize light capture. Its Neostar series targets premium residential rooftops with efficiencies confirmed by pv-magazine at up to 24.3% in early 2025 shipments, while the larger Comet series (600-630 W) addresses commercial and industrial rooftops. AIKO won the 2025 SolarQuotes Installers' Choice Awards in Australia, and third-party testing has confirmed superior shading tolerance compared with PERC and standard TOPCon alternatives. For a buyer prioritizing peak efficiency on space-constrained rooftops and long-term bankability, AIKO is the clearer choice in 2025, particularly for premium residential or C&I projects where financing is involved. TommaTech remains a reasonable option for buyers operating in European supply chains who need a locally accessible, competitively priced PERC or TOPCon module with BIPV or flexible variants - segments where AIKO does not compete. The two brands occupy genuinely different niches and are not directly interchangeable. \---LINKS--- \- https://www.pv-magazine.com/2025/02/07/aiko-launches-new-rooftop-solar-panels-with-24-3-efficiency/ \| Aiko launches new rooftop solar panels with 24.3% efficiency - pv magazine \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/ \| AIKO achieves BloombergNEF Tier 1 status \| article \- https://www.enfsolar.com/tommatech \| TommaTech GmbH company profile - ENF Solar \| article \- https://www.pv-tech.org/aiko-solar-n-type-abc-module/ \| Aiko Solar adds products to n-type ABC module series - PV Tech \| article Sources: \- \[Aiko launches new rooftop solar panels with 24.3% efficiency\](https://www.pv-magazine.com/2025/02/07/aiko-launches-new-rooftop-solar-panels-with-24-3-efficiency/) \- \[Aiko Solar panels review - SolarQuotes\](https://www.solarquotes.com.au/panels/aiko-solar-review.html) \- \[AIKO achieves BloombergNEF Tier 1 status\](https://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/) \- \[TommaTech GmbH company profile - ENF Solar\](https://www.enfsolar.com/tommatech) \- \[Aiko Solar adds products to n-type ABC module series - PV Tech\](https://www.pv-tech.org/aiko-solar-n-type-abc-module/) Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
