This translates to easier financing for institutional projects and a higher level of guarantee security compared to most of its competitors. - **Independent Kiwa PVEL Top Performer 2025 Award** - The Meteor series has been awarded the Kiwa PVEL Top Performer Award 2025 and received a 5-star rating ('Excellent') in the PV Magazine test. This is an independent verification of durability and actual performance parameters, which is lacking in the offerings of KDM Kingdom Solar or Lina Energy, which are included in the peer comparison list. - **Performance 22.57% above the peer group median** - The maximum efficiency of 22.57% exceeds that of the KDM SERIES (22.5%) and Lina Energy LEPV 132 ULTRA PREMIUM (22.37%), which, with a typical roof area of 40 m², translates to approximately 100 Wp more installed power compared to Lina Energy. This allows for optimization of installations on roofs with limited space. - **Low thermal expansion coefficient: -0.29%/°C** - N-type TOPCon cells exhibit a coefficient of -0.29%/°C, compared to the typical -0.35%/°C for older PERC modules. In Polish summer conditions (module temperature ~65°C, a difference of 35°C from STC), this translates to approximately 2% higher energy yield compared to PERC technology. - **30-year double warranty with retention rate >87.4%** - The manufacturer offers both a 30-year product warranty and a power output guarantee (>87.4% after 30 years), while most of the market – including typical KDM and Lina Energy modules – standardly offers a 25-year warranty. The glass-to-glass design eliminates the risk of EVA degradation and ensures long-term module sealing. ## Cons - **Performance lower than Luxor NON-REFLECT** - The maximum efficiency of 22.57% is 0.29% lower than Luxor ECO LINE N-TYPE TOPCon NON-REFLECT (22.86%). On a standard module measuring 1722×1134 mm, this translates to approximately 1.2% less peak power with the same surface area. For investors with very limited roof space, Luxor offers a power density that is unavailable in this series. ## About this series The AE Solar METEOR CMD-108BDS series is a breakthrough solution utilizing advanced **N-type ABC cell technology**, which completely eliminates front shading caused by busbars. By moving all contacts to the back of the cell, these panels achieve outstanding efficiency and offer a minimalist, black design ideal for modern architecture. The absence of front-side metallization is not just about aesthetics, but primarily about maximizing the absorption area, which directly addresses the problem of limited installation space on the roofs of single-family homes. **Bifacial double-glass construction** allows for additional energy yield from reflected radiation, significantly increasing the profitability of ground-mounted and carport installations. These modules stand out with negligible light-induced degradation, providing users with peace of mind and production stability for many years. The applied **All Back Contact architecture** minimizes the risk of micro-cracks and improves performance at high temperatures, distinguishing them from standard TOPCon modules. This solution is dedicated to the most demanding investors who expect the **highest power density** and uncompromising quality of workmanship. Exceptional resistance to extreme weather conditions makes the Meteor series one of the strongest points in the premium module range on the Polish market today. ## Notable figures - 22.6% module efficiency - 0.6pp better than the \*\*TOPCon 400-450W\*\* median of 22.0% - At 225.7 W/m² power density, this panel generates 5.5 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 23.5 kg, this panel is 1.5 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What distinguishes the ABC technology used in the AE Solar METEOR CMD-108BDS from standard TOPCon panels? The All Back Contact (ABC) technology moves all metallic contacts to the back of the cell, eliminating the need for collecting strips on the front surface. Compared to standard TOPCon modules, this results in a larger light absorption area, higher efficiency reaching 22.57%, and a reduced risk of microcracks. The result is a uniform, black panel with no visible electrodes. ### What is the warranty on AE Solar METEOR CMD-108BDS panels, and exactly what does it cover? The METEOR CMD-108BDS series is covered by a 30-year product warranty and a 30-year warranty on power output. After 30 years, the panel should maintain at least 87.4% of its nominal power output. The warranty is provided by AE Solar, a German-based manufacturer classified as Tier 1, which ensures financial stability and the certainty of claims processing throughout the warranty period. ### Are AE Solar METEOR CMD-108BDS panels suitable for ground-mounted or rooftop installations? Yes, the bifacial design with double glass is particularly beneficial in ground-mounted and wind-powered installations. The panel absorbs both direct radiation from the front and reflected radiation from the ground or water surfaces, which effectively increases energy yield. Its resistance to ammonia (IEC 62716), saline mist (IEC 61701), and strong winds makes the Meteor series suitable for use in challenging terrain conditions. ### What is the weight and dimensions of the AE Solar METEOR CMD-108BDS 440W panel? The 440 W panel has dimensions of 1721 × 1133 × 30 mm and weighs 23.5 kg. The double-glazed design increases the weight compared to standard modules, so it's important to ensure that the roof or ground structure can support the appropriate load before installation. However, the panel's dimensions are within the typical standards used by Polish installers. ### How do AE Solar METEOR CMD-108BDS panels perform in high temperatures, for example, during the summer in Poland? The temperature coefficient of the CMD-108BDS series is as low as -0.29%/°C, which is among the best results in the premium panel class. For comparison, the average PERC module loses approximately -0.35%/°C. The All Back Contact architecture also reduces the heating of the cell front, meaning that the hot Polish summers have a less negative impact on energy production compared to standard modules. ### Is AE Solar a reliable manufacturer, and do they have an authorized service center in Poland? AE Solar is a German-based company that has been operating since 2003 and is classified as Tier 1 by Bloomberg NEF, which confirms its financial stability and product credibility. The panels are sold through authorized distributors in Poland, and certifications such as IEC 61215, IEC 61730, and ISO 9001:2015 guarantee compliance with European standards. It is advisable to confirm the warranty terms with the distributor before making a purchase. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmd-108bds-420w-440w-ver25-4-1-8f73d380c12e.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, lighter, +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, cooler, +1.7 pp | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -160 W, -8.2 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -155 W, -8.0 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -150 W, -7.7 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -145 W, -7.4 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -140 W, -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-108bds-440 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
