This means full coverage for the typical lifespan of a commercial installation without the need to renegotiate terms. - **BNEF Tier 1 – the only European project with 'high bankability'** - AE Solar has been included in the BNEF Tier 1 list for the 16th consecutive quarter (Q1 2025), and as the only European manufacturer, it achieved a "high bankability" rating in 2024. The bankability index increased from 26% (2023) to 50% (2024), which directly reduces project risk when financing with banks and insuring the installation. - **Efficiency of 22.31% – above average compared to peers** - The top-performing variant of the series achieves 22.31% at 435 Wp, while its direct counterparts – Luxen LUXPOWER N5 and ZNShine ZXM7-UHLDD108 – reach 22.28%, and Solitek SOLID Blackstar reaches 22.27%. The small difference confirms the series' leading position in the 108-cell segment. - **Double glazing + bifaciality = increased durability and higher energy yield** - The double-glass construction ensures resistance to ammonia, saline mist, sand, and mechanical loads – which are important for industrial and agricultural installations. The bifacial design allows for additional energy generation from the back side when the ground reflectance (albedo) is ≥0.2 (light gravel, concrete, snow), which is particularly beneficial for ground-mounted and flat-roof installations. ## About this series The AE Solar METEOR CMD-108BDE (Black Double-Glass) series is a range of modules designed for maximum performance, where both efficiency and durability are crucial. The use of **N-type TOPCon** cells ensures stable operation over a long period and better light utilization in conditions of lower sunlight. The **bifacial** design allows for energy generation from both sides, which helps to increase production on bright surfaces, flat roofs, and ground-mounted structures. A key feature of this version is **double-glass**, which improves resistance to moisture, corrosion, and mechanical stress - a significant advantage in installations exposed to harsh weather conditions. The **full black** finish, valued in premium installations where aesthetics are important, adds to the overall appeal. This is a good choice for homes, businesses, and commercial projects that require high performance, a robust structure, and predictable yields without compromising on quality. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 218.0 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - At 23.5 kg (1.5 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is the N-type TOPCon technology used in AE Solar METEOR CMD-108BDE panels, and how does it differ from PERC? N-type TOPCon cells have a lower degradation rate than standard PERC cells, which means that the panel maintains a high power output for a longer period. In the METEOR CMD-108BDE series, this translates to a temperature coefficient of only -0.29%/°C, as well as better performance under low sunlight conditions. On cloudy days or at low sun angles, the module produces proportionally more energy than older technologies, which is particularly important in the Polish climate. ### What is the warranty on AE Solar METEOR CMD-108BDE panels? The METEOR CMD-108BDE series comes with a 30-year product warranty covering physical defects and workmanship, as well as a 30-year performance warranty. AE Solar is a Tier 1 manufacturer based in Germany, which further strengthens the credibility of these warranties. This extended linear warranty allows for precise investment return planning throughout the entire lifespan of the installation. ### Do AE Solar METEOR CMD-108BDE panels suitable for flat roofs and ground-mounted installations? Yes, this is one of the natural applications of this type of panel. Thanks to its bifacial design, the panel also generates energy from the back side, and this effect is most effective on flat roofs with a light-colored membrane or gravel, as well as on ground-mounted structures with a light-colored surface. The double-pane glass also provides protection against moisture and mechanical loads, typical for installations exposed to snow and wind. ### What distinguishes the double-glass version of the AE Solar METEOR CMD-108BDE series from a standard panel with a backsheet? In the CMD-108BDE version, the rear glass replaces the backsheet, significantly increasing resistance to moisture, corrosion, and mechanical stress. Double-glass is better suited for humid environments, such as green roofs or agro-photovoltaic farms. A drawback is its slightly higher weight, approximately 23.5 kg, which should be considered when designing a roof structure or selecting a mounting system. ### Do the AE Solar METEOR CMD-108BDE panels perform effectively in winter and on cloudy days? Yes. N-type TOPCon cells exhibit higher efficiency under diffuse light compared to older PERC technology, which directly improves energy production on cloudy days and with low sun angles. The -0.29%/°C temperature coefficient also means that the module operates closer to its rated power on cold, sunny days, unlike in the summer when high panel temperatures limit performance. ### What are the dimensions and weight of the AE Solar METEOR CMD-108BDE 435 W panel, and does it fit on a typical pitched roof? The panel has dimensions of 1721 × 1133 × 30 mm and weighs approximately 23.5 kg. This is a typical size for 108-cell modules, compatible with standard mounting systems. When installing on a pitched roof, it is important to check the available surface area and the roof's load-bearing capacity, as double-glazed panels are slightly heavier than those with a film. For larger installations, it is advisable to consult with a designer or installer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmd-108bde-415w-435w-sc-11-5-ver25-9-1-0707cd5d5846.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +2.2 pp, +10 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, lighter, +2.0 pp | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, lighter, +2.0 pp | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, +2.0 pp | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, heavier, +2.0 pp | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, cooler, +2.0 pp | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -145 W, -7.4 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -140 W, -7.2 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -135 W, -6.9 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -130 W, -6.7 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -125 W, -6.4 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/ae-solar-cmd-108bde-425w 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.
