The company achieved BloombergNEF Tier 1 bankability status in Q3 2024 and has expanded production capacity to over 20 GW per year as of early 2025, placing it firmly among the upper tier of global module suppliers. NeMo is the flagship module series of Heckert Solar GmbH, a German manufacturer based in Chemnitz, Saxony, with over two decades of production history. Heckert operates exclusively in Germany - across sites in Chemnitz and Thuringia - at a capacity in the hundreds of MWp range, a deliberately smaller scale than the multi-GW Chinese producers. Heckert Solar does not appear on recent BloombergNEF Tier 1 lists based on available sources, giving AIKO a clear advantage in project-finance and institutional procurement contexts. AIKO panels target the premium end of the residential and commercial rooftop segment. The Neostar series has held the world record for commercially available module efficiency at around 24.3-24.4% since 2023 - a figure cited consistently across independent reviews and confirmed by the 2025 SolarQuotes Installers' Choice Awards. That performance premium comes at a higher price per watt, making AIKO panels most competitive on space-constrained rooftops where output density justifies the cost. NeMo modules are positioned as high-reliability, Made-in-Germany products appealing to European buyers who prioritize supply-chain transparency and local manufacturing credentials. The NeMo 3.0 and 4.2 series use standard monocrystalline cell technology and carry strong mechanical certifications - tested to snow loads up to 5,400 Pa - targeting mid-tier residential and small commercial installations in European markets. For most buyers in 2025, AIKO is the stronger default where maximum efficiency, proven bankability, and broad installer availability are the priorities. NeMo from Heckert Solar remains a credible niche choice for European buyers who require EU-origin manufacturing or face procurement rules that favor domestic supply chains, even though Heckert operates at a fraction of AIKO's global scale. These two products occupy genuinely different market positions, so the right answer depends on geography and whether institutional bankability is a hard requirement. \---LINKS--- \- https://www.pv-magazine.com/2025/12/23/aiko-achieves-34-76-efficiency-for-2-terminal-perovskite-silicon-tandem-solar-cell/ \| AIKO achieves 34.76% efficiency for perovskite-silicon tandem cell \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| AIKO Solar Panels - SolarQuotes expert review \| review \- https://mcelectrical.com.au/debunking-the-aiko-solar-panel-hype-a-real-world-performance-test/ \| Debunking the AIKO Solar Panel Hype - real-world performance test \| review \- https://comparepv.com/reviews/nemo \| NeMo Solar Panels Review 2026 - Pros, Cons and Specs \| review \- https://www.photon.info/en/news/heckert-solar-expands-production-capacity-240-mw \| Heckert Solar expands production capacity \| article Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
