This difference of 1.1–2.0% translates into a significantly higher energy yield per square meter of roof area. - **ABC Technology – Low Temperature Coefficient** - 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. - **Free degradation – ≥88.85% after 30 years** - 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. - **BNEF Tier 1 – bankability confirmed for Q1 2026** - 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. - **30-year power guarantee with a high retention rate.** - 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. ## Cons - **IEC Class C fire extinguisher (not Class A)** - 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. ## About this series 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. ## Notable figures - 24.6% module efficiency - 0.9pp better than the \*\*Back Contact 600-650W\*\* median of 23.7% - 245.8 W/m² power density - 8.9 W/m² more than \*\*Back Contact 600-650W\*\* median (236.9 W/m²), more power per roof area - At -0.26%/°C, hot weather performance is typical for \*\*Back Contact 600-650W\*\* panels - 27.0 kg weight - 5.3 kg lighter than \*\*Back Contact 600-650W\*\* median (32.3 kg), reducing installation effort - In the top 0% for efficiency among all Back Contact panels ## Questions ### What is the ABC technology used in AIKO Comet 3N72e panels, and why is it important? ABC (All Back Contact) is a technology for n-type solar cells, in which all electrical contacts are located on the back of the cell. This allows the front surface of the panel to be fully active, without metallic strips that block light. In practice, the AIKO Comet 3N72e achieves an efficiency of up to 25.2%, which is one of the highest results available on the market for mono-glass modules. ### What is the warranty on Aiko Comet 3N72e solar panels? The manufacturer offers a 15-year product warranty for material and workmanship defects, as well as a 30-year linear warranty for power output. Degradation is no more than 1% in the first year and a maximum of 0.35% per year from the second year, which means that after 30 years, the panel should maintain at least 87.4% of its nominal power. These parameters are significantly better than those of standard PERC modules. ### How does the AIKO Comet 3N72e perform in hot and high-temperature conditions? The temperature coefficient of the Pmax power for PERC modules is as low as -0.26%/°C, while typical PERC modules lose approximately -0.35%/°C. This means that at 45°C, the temperature causes a power loss of approximately 5.2% instead of 8.75% in PERC. In practice, on the roofs of industrial halls and warehouses, where modules heat up significantly in the summer, this translates to a significantly higher daily energy yield. ### Is the AIKO Comet 3N72e 650W solar panel suitable for the roof of an industrial building? Yes, the 3N72e mono-glass series is designed for both pitched and flat commercial roofs. The module operates within a temperature range of -40°C to +85°C and has a maximum system voltage of 1500 V DC, allowing for the creation of longer strings with fewer chains. It is advisable to check the weight of the module and the roof structure's load-bearing capacity before installation, as specified in the datasheet. ### Is the AIKO Comet 3N72e a bifacial module? No, the Comet 3N72e model in the mono-glass version is a single-sided (monofacial) module. The glass is mounted only on the front, while the back is a durable backsheet. This means there is no additional production of light reflection from the substrate, but it also results in a lighter weight and simpler installation compared to the dual-glass bifacial versions offered by Aiko in other series. ### Is the AIKO Comet 3N72e series still available for sale? Yes, the AIKO Comet 3N72e (625W-650W) series is currently available and has not been discontinued. AIKO Solar is a Tier 1 manufacturer based in China, and modules from this series are regularly imported to Europe. When planning larger installations, it is advisable to confirm the availability of specific power ratings (e.g., 650W) with a distributor, as lead times for peak power ratings may be longer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/comet-3n72e-aiko-a-mae72mw-625w-650w-76363292a5c3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +15 W, +0.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +45 W, heavier, +0.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +40 W, heavier, +0.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +10 W, +0.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +35 W, heavier | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +35 W, heavier | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Very close match | | [AIKO M530M-144](https://comparepv.com/panel/aiko-m530m-144) | 530 W | -105 W, hotter, -4.1 pp | | [AIKO M535M-144](https://comparepv.com/panel/aiko-m535m-144) | 535 W | -100 W, hotter, -3.9 pp | | [AIKO M540M-144](https://comparepv.com/panel/aiko-m540m-144) | 540 W | -95 W, hotter, -3.7 pp | | [AIKO M545M-144](https://comparepv.com/panel/aiko-m545m-144) | 545 W | -90 W, hotter, -3.5 pp | | [AIKO M550M-144](https://comparepv.com/panel/aiko-m550m-144) | 550 W | -85 W, hotter, -3.3 pp | | [AIKO AIKO-A-600-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-600-mah72mw) | 600 W | -35 W, hotter, -1.4 pp | | [AIKO AIKO-A-605-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-605-mah72mw) | 605 W | -30 W, hotter, -1.2 pp | | [AIKO AIKO-A-610-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-610-mah72mw) | 610 W | -25 W, hotter, -1.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Heavier, -0.2 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a635-mae72mw Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
