The difference of approximately 1% compared to the first two indicates a significantly higher energy yield from the same roof area or ground space. - **Temperature coefficient: -0.26%/°C** - The ABC (Back Contact) technology moves the metallization to the back of the cell, improving heat dissipation. The -0.26%/°C coefficient is better than the typical values for TOPCon (-0.30%/°C) and PERC (-0.34%/°C), which translates into measurable lower power losses compared to standard modules during the hot Polish summers. - **30-year linear warranty with ≥88.85% power output** - AIKO claims to maintain ≥88.85% of its rated power after 30 years, with a degradation rate of ≤0.35% per year, which exceeds the typical TOPCon modules that guarantee ~87.4% after 30 years. This translates to a higher cumulative energy yield (LCOE) throughout the entire lifespan of C&I installations. - **Construction of dual-glass 2.0+2.0 mm – mechanical durability** - The 2.0+2.0 mm tempered glass on both sides provides better protection against micro-cracks, moisture (without EVA on the back), and the PID effect compared to single-pane glass. This is a key advantage for industrial and farm installations, where mechanical loads (snow, wind) are greater. - **Bifaciality in Back Contact Technology** - The combination of ABC cells with a dual-glass, bifacial design eliminates shading losses caused by wires on the front, while also allowing for the absorption of reflected radiation from the ground (typical albedo of +5–15% of energy). This effect is not available in mono-glass models in the same price range. ## Cons - **Premium price compared to TOPCon tier-1** - AIKO ABC modules are priced approximately 20–30% higher than comparable Jinko Tiger Neo or Canadian Solar TOPCon modules (market data for AU/EU 2024–2025). In C&I projects that are highly sensitive to capital expenditure (CAPEX), where the performance difference of approximately 1% does not compensate for the higher unit cost, the price premium requires individual profitability analysis. ## About this series The AIKO Comet 1N+ Dual-Glass (610W-630W) series is designed for maximum yield from every square meter of commercial and industrial installations. Its key advantage is the application of **N-type cells in ABC technology (back contact)**, where conductive elements are moved to the rear side of the cell. The effect is cleaner front side operation, better light utilization, and high visual cleanliness without compromising performance. The dual-glass (**glass-glass**) version targets longevity - the construction is mechanically stronger and better withstands typical operating conditions for roof of halls, warehouses, and carports. In practice, it helps reduce the risk of micro-cracks, thereby minimizing power degradation over time - a tangible benefit for investors focusing on LCOE and reliability. Modules also feature **optimized performance under partial shading**, which is crucial where roof tiles, dirt, or diffuse light occur. Additionally, **behavior at high temperatures** supports stable energy production during summer, when many standard panels suffer the most. This is the choice for projects where yield, safety, and robust construction matter just as much as catalog specifications. ## Notable figures - Efficiency of 24.2% matches the \*\*Back Contact 600-650W\*\* median - At 241.9 W/m² power density, this panel generates 5.0 W/m² more per unit area than \*\*Back Contact 600-650W\*\* median (236.9 W/m²) - Temperature coefficient of -0.26%/°C matches the \*\*Back Contact 600-650W\*\* median - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces - #184 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What distinguishes the ABC technology used in AIKO Comet 1N+ panels from standard N-type cells? In the All Back Contact (ABC) design, all conductive contacts are moved to the back of the cell – the front surface is completely free of metallic contacts. This allows for more surface area to absorb light, eliminating losses due to shading from busbars (metal strips). The result is a module efficiency of up to 23.6%, which is significantly higher than that of typical N-type TOPCon or PERC cells of the same power class. ### What warranty does AIKO offer on the Comet 1N+ Dual-Glass series? AIKO offers a 15-year product warranty (for material and workmanship defects) and a 30-year linear power warranty. Degradation in the first year is a maximum of 1%, and does not exceed 0.35% per year from the second year onwards. This means that after 30 years, the module should retain at least approximately 87.4% of its nominal power – this is one of the best indicators in the commercial segment. ### Is the AIKO Comet 1N+ Dual-Glass 630W suitable for a factory or warehouse roof? Yes, this series was specifically designed for roofs of industrial halls, warehouses, and farms. The dual-glass construction provides greater mechanical strength and resistance to moisture compared to standard laminates with film, which translates into a longer lifespan in demanding industrial conditions. The modules weigh approximately 32.5 kg with dimensions of 2278×1134×30 mm, so it's important to check the roof's load-bearing capacity before installation. ### How does the AIKO Comet 1N+ Dual-Glass window perform in high summer temperatures? The temperature coefficient for the module's power output is -0.26%/°C, which is among the lowest figures for commercial modules. For comparison, standard PERC (Passivated Emitter and Rear Cell) modules typically exhibit a temperature coefficient of -0.35%/°C or higher. In practice, this means that when the panel is heated to 70°C, the AIKO Comet 1N+ module loses approximately 12% of its power, while a conventional module loses as much as 18%. This translates to a significantly higher energy yield on hot summer days. ### Are the AIKO Comet 1N+ Dual-Glass modules bifacial, and what does this mean in practice? Yes, the Comet 1N+ Dual-Glass series is bifacial – the rear glass allows light reflected from the ground (albedo) to reach the back side of the module, increasing the total energy yield. In commercial installations on bright roofs or on light-colored surfaces, this additional gain can range from 5 to 15% of the annual energy production compared to a monofacial module with the same rated power. ### Is the AIKO Comet 1N+ Dual-Glass (610W-630W) series still available for sale? Yes, this series has not been discontinued and remains an active product offering from AIKO in the commercial and industrial sector. AIKO is a manufacturer on Bloomberg NEF's Tier 1 list, which makes it easier for banks and funds to finance projects. However, when purchasing, it is advisable to confirm the current delivery schedule with the distributor, as the high individual power output of 610-630 W makes these modules particularly attractive in solar farm projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/comet-1n-plus-184-aiko-a-mah72dw-610-630w-2278x1134x30mm-dsd-5e7afe79c1fc.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +25 W, lighter, +1.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +0.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +20 W, lighter, +0.8 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +0.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +0.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +15 W, lighter, +0.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, +0.6 pp | | [AIKO M530M-144](https://comparepv.com/panel/aiko-m530m-144) | 530 W | -95 W, hotter, -3.7 pp | | [AIKO M535M-144](https://comparepv.com/panel/aiko-m535m-144) | 535 W | -90 W, hotter, -3.5 pp | | [AIKO M540M-144](https://comparepv.com/panel/aiko-m540m-144) | 540 W | -85 W, hotter, -3.3 pp | | [AIKO M545M-144](https://comparepv.com/panel/aiko-m545m-144) | 545 W | -80 W, hotter, -3.1 pp | | [AIKO M550M-144](https://comparepv.com/panel/aiko-m550m-144) | 550 W | -75 W, hotter, -2.9 pp | | [AIKO AIKO-A-600-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-600-mah72mw) | 600 W | Hotter, lighter, -1.0 pp | | [AIKO AIKO-A-605-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-605-mah72mw) | 605 W | Hotter, lighter, -0.8 pp | | [AIKO AIKO-A-610-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-610-mah72mw) | 610 W | Hotter, lighter, -0.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +10 W, lighter, +0.4 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a625-mah72dw Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
