Bankability increased from 26% (2023) to 50% (2024), making it easier for banks and investment funds to finance commercial projects. - **Low thermal expansion coefficient (-0.29%/°C)** - The temperature coefficient of power at -0.29%/°C is better than typical PERC modules (-0.34 to -0.37%/°C), which translates to a higher actual power output on hot, sunny days. For the Polish climate, this means lower power losses during the peak summer months. - **30-year product and performance warranty** - AE Solar offers both a 30-year product warranty and a 30-year linear performance warranty, maintaining ≥87% of the nominal power output. Most Tier 1 Asian manufacturers (JA Solar, Trina Solar) typically offer a standard 25-year performance warranty, so the METEOR CMD-108 clearly exceeds the market standard. - **Class A fire resistance rating and Class 4 hail resistance rating** - The panel has a fire-resistant rating of Class A (the highest rating) and a hail resistance rating of Class 4 (withstanding 25 mm diameter hailstones at a speed of 23 m/s). The Class A rating expands the installation possibilities for buildings where fire safety regulations require panels of Class B/C. - **Efficiency of 22.57% – top performer in the 108-cell segment** - The maximum efficiency of 22.57% exceeds two out of three comparable products: Lina Energy LEPV 132 ULTRA PREMIUM (22.37%) and KDM Kingdom Solar (22.5%). The higher power density directly reduces the required mounting area for the same installed power. ## Cons - **87% power guarantee after 30 years – below the segment leader** - The Luxor Solar ECO LINE N-TYPE TOPCON non-reflective panel guarantees ≥89% power after 30 years, which is 2 percentage points higher than the METEOR CMD-108 (≥87%). For a 10 kWp installation, this difference translates to approximately 200 Wp less of guaranteed peak power after 30 years of operation. - **There is no dual-sided version of the CMD-108 series.** - The METEOR CMD-108 series is exclusively monofacial. In the same power class and technology, Luxor Solar offers a glass-glass bifacial variant, which, under favorable ground albedo conditions (e.g., light gravel, snow, or a white membrane), can generate an additional 5–15% annual yield. ## About this series The AE Solar METEOR CMD-108 series redefines performance standards on the Polish photovoltaic market thanks to the use of **N-Type TOPCon technology**, which guarantees significantly higher efficiency compared to traditional modules. It solves the key problem of power loss at high temperatures, making it an ideal choice for sunny roofs of residential and commercial buildings. A unique feature of this series is the use of **rectangular half-cut cells**, which not only increase the active surface area of the panel but also improve current flow and reduce the risk of micro-cracks. Investors appreciate these modules for their exceptional **resistance to potential-induced degradation (PID)**, ensuring the long-term financial stability of the investment. Unlike cheaper alternatives, the METEOR series offers excellent performance characteristics in diffused light, which translates into higher yields during the winter months in the Polish climate. The use of a **reinforced frame construction** makes the panels resistant to extreme snow and wind loads, ensuring the safety of the entire installation. It is a substantive choice for those seeking a compromise between the compact 108-cell size and a powerful output, allowing for the maximum utilization of every square meter of available mounting space. ## Notable figures - At 22.6% efficiency, this panel is 0.6pp above typical \*\*TOPCon 400-450W\*\* modules (median: 22.0%) - 225.7 W/m² power density - 5.5 W/m² more than \*\*TOPCon 400-450W\*\* median (220.2 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 20.3 kg, this panel is 1.7 kg lighter than \*\*TOPCon 400-450W\*\* median (22.0 kg) - easier handling during installation - In the top 28% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of the AE Solar METEOR CMD-108 panel, and how does it compare to competing products? The AE Solar METEOR CMD-108 module achieves a maximum power output of 440 W with an efficiency of up to 22.57%. This is achieved through the N-Type TOPCon technology, which generates more energy from the same surface area compared to older PERC modules. In practice, this means that on a roof with limited surface area, you can obtain more kilowatt-hours per year compared to using typical polycrystalline or monocrystalline PERC modules from previous generations. ### What warranty period does the AE Solar METEOR CMD-108 series cover, and specifically, what is guaranteed? The manufacturer offers a guarantee of up to 30 years on both the product and its output power. The output power guarantee ensures that, after three decades of use, the panel will maintain at least 87% of its nominal power. This is one of the longest warranties available on the Polish photovoltaic market, and it is a significant factor in calculating the long-term return on investment. ### Do the AE Solar METEOR CMD-108 panels perform effectively in winter and under typical cloudy conditions for Poland? Yes. N-Type TOPCon technology is characterized by excellent performance in low-light conditions, which is particularly important in the Polish climate from November to February. The low temperature coefficient also reduces power losses during summer heatwaves. Compared to PERC modules, the METEOR CMD-108 series generates more energy throughout the year, not just in full sunlight. ### What are the dimensions and weight of the AE Solar METEOR CMD-108 440W panel, and will it fit on a typical roof? The panel measures 1721 × 1133 × 30 mm and weighs approximately 20.2 kg. The compact format of 108 cells makes the module smaller than popular 120- or 144-cell models, which simplifies installation on roofs with limited span or with complex obstructions (chimneys, skylights). The weight of under 21 kg allows for safe handling by a single person during installation. ### What are half-cut rectangular cells in the AE Solar METEOR CMD-108 series, and why are they important? Half-cut cells are traditional cells that have been cut in half, which reduces internal electrical resistance and lowers the risk of micro-cracks forming during transportation and use. The rectangular shape of the cells increases the active surface area of the panel, allowing more of the glass to actually generate energy. An additional advantage is improved resistance to partial shading – even a partially shaded part of the panel does not prevent the entire module from functioning. ### Is AE Solar a reputable manufacturer – where is the company located, and is it a Tier 1 supplier? AE Solar is a German-based company that has been operating in the market since 2003 and is classified by independent agencies as a Tier 1 manufacturer. This means that it meets strict financial and quality criteria, and its modules are accepted by banks as collateral for financing large-scale installations. For the Polish consumer, Tier 1 certification guarantees that the company will remain in operation throughout the duration of the 30-year warranty. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmd-108-420w-440w-sc-11-5-ver25-9-1-2c590de1cbba.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +1.9 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +1.9 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.7 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.7 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, heavier, +1.7 pp | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -160 W, heavier, -8.2 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -155 W, heavier, -8.0 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -150 W, heavier, -7.7 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -145 W, heavier, -7.4 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -140 W, heavier, -7.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +1.9 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-cmd-108-440 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
