Efficiency leader, no clear weak spot
The AIKO Comet 3N72e (mono-glass) series is designed to maximize energy yield from every square meter of roof space - where high power density and real investment profitability are crucial. The key advantage is the n-type ABC (all back contact) cell technology, which enables a more efficient active surface, an aesthetically pleasing module design, and no performance loss due to traditional front-side elements.
In practice, the Comet 3N72e helps address common challenges in commercial installations: better performance under partial shading (reduced losses during the day), more stable power output in high temperatures, and slower degradation and high parameter repeatability over the long term. The mono-glass construction facilitates installations where optimal balancing between mass, mounting, and performance is a priority.
This solution performs exceptionally well on the rooftops of halls, warehouses, retail spaces, and public utility buildings, where limited space demands uncompromising efficiency and a rapid return on investment.
Ranking
Signals from the data
Commercial, utility-scale and hot-climate.
Top 1% of the Back Contact 650-700 W segment, against a median of 24.40%. Ranked 1st in the whole database.
Top 2% of the Back Contact 650-700 W segment, against a median of 244.3. Ranked 2nd in the whole database.
Top 3% of the Back Contact 650-700 W segment, against a median of 49.8. Ranked 182nd in the whole database.
The module's efficiency ranges from 24.2-25.2%, while the direct equivalents in the same power range (625-650 Wp) achieve: BYD AURO N 23.25%, Astronergy ASTRO N5 23.3%, Jinko Tiger Neo 24.06%. This difference of 1.1-2.0% translates into a significantly higher energy yield per square meter of roof area.
The All Back Contact architecture eliminates shading of front electrodes and ensures a Pmax temperature coefficient of -0.26%/°C - better than typical TOPCon modules (-0.29 to -0.30%/°C). During peak summer sunlight (when the module reaches 65°C), the difference in energy production is realistically around 1.5% more than a typical TOPCon module.
The datasheet guarantees ≤1% degradation per year from year 1, and ≤0.35%/year from year 2 to year 30, resulting in ≥88.85% retention after a full lifespan. For comparison: TOPCon modules of the same generation retain approximately 87.4% after 30 years, while standard PERC modules retain approximately 84.8% after 25 years - this represents approximately 1.5% higher cumulative energy yield over 30 years.
AIKO is listed on BloombergNEF's Tier 1 PV Module Manufacturers (Q1 2026 update), meeting the requirement of supplying modules to at least 6 >10 MW projects funded by independent commercial banks within 24 months. This makes it easier for investors in commercial and industrial (C&I) projects to secure financing and obtain insurance coverage.
The linear warranty covers 30 years with a guaranteed minimum power output of ≥88.85% - assuming a 650 Wp system, this translates to ≥577.5 Wp at the end of the warranty period. The product warranty is 15 years, which is the standard for premium products in this power range.
The manufacturer's official datasheet indicates IEC 61730 Class C fire resistance. For installations in buildings requiring a higher fire resistance rating (e.g., public buildings with specific local or insurance requirements for Class A), this may constitute a formal limitation and require consultation with a designer or insurer.
- 25.2% module efficiency - 0.8pp better than the Back Contact 650-700W median of 24.4%
- Power density of 251.6 W/m² packs 7.3 W/m² more into the same footprint vs Back Contact 650-700W median (244.3 W/m²)
- At -0.26%/°C, hot weather performance is typical for Back Contact 650-700W panels
- 27.0 kg weight - 5.8 kg lighter than Back Contact 650-700W median (32.8 kg), reducing installation effort
- Ranked #1 out of 14129 panels for efficiency in the database
