Aiko Comet 3N72 AIKO-A670-MDE72Mw

AIKO Solar Comet 3N – maximum conversion for your projects

The latest Comet series from AIKO Solar is the world’s most efficient solar panel (1/2026). The third generation combines the best features of the previous series – it builds on the record-breaking efficiency of the first series and retains the integrated optimisation for partial shading from the second. Thanks to this unique combination, the panel maintains high conversion efficiency even under partial shading and optimises panel performance at the cell level. Aiko’s third-generation panels once again raise the technological bar and, compared to TOPCon cells, achieve up to 50 W more power from the same surface area. 

We now offer a 670 W panel with a record efficiency of 24.8 per cent. The panel also maintains a width of 1134 mm – thus avoiding increases in construction and cabling costs, which can become significantly more expensive on large-scale projects. AIKO’s standard specification features back-contact ABC cells, containing the highest-quality N-type silicon. The panel is suitable for all commercial projects, particularly those where there is pressure to achieve a rapid return on investment. Thanks to its new features and the balance of efficiency, power output and quality, Aiko offers the greatest potential for maximising long-term returns.

Panel manufacturer: AIKO Solar

AIKO Solar was founded in 2009 and has many years’ experience in the development and manufacture of solar cells. The innovative All-Back-Contact (ABC) technology was developed in the company’s own laboratories. AIKO Solar now uses this technology in its own panels, achieving top-class efficiency. With a third of its workforce dedicated to R&D, Aiko regularly introduces innovative technologies and patents, such as optimisation for partial shading. Aiko holds a patent for tubular PERC cells, which today account for 70% of global production.
