The bankability index has increased from 26% (2023) to 50% (2024), which has a direct impact on projects that involve bank or leasing financing. - **Temperature coefficient: -0.29%/°C** - The efficiency of -0.29%/°C (Pmax) places the METEOR module significantly above older PERC modules (-0.35%/°C). At a typical module temperature of 55°C in Poland during the summer, the loss is approximately 8.7% compared to 10.5% for PERC - resulting in a real, higher summer gain without any changes to the installation. - **30-year product warranty and warranty coverage** - Both the product and performance warranties are 30 years long - 5 years longer than the industry standard of 25 years (used by companies such as Trina Solar and JA Solar). The manufacturer guarantees >87% of the nominal power output after 30 years, which reduces the residual risk for the installer. - **Bifacial double-glass with half-cut solar cells** - Double-pane glass (2+2 mm) eliminates the risk of PID degradation and provides environmental protection to Class C2/salt mist/ammonia. The combination of bifacial + half-cut technology minimizes losses in partially shaded conditions and allows for the recovery of 5-15% additional energy from reflected light (e.g., from roofs, membranes, gravel, and soil). - **Efficiency of up to 22.57% - at the upper end of the segment** - Among direct peer comparisons, METEOR (22.57%) outperforms KDM SERIES (22.5%) and Lina Energy LEPV 132 ULTRA PREMIUM (22.37%), only slightly trailing Luxor ECO LINE NON-REFLECT (22.86%). The high power density allows for 440 Wp per 108 cells in a format of 1721 × 1133 mm. ## Cons - **Higher weight: 23.5 kg vs. glass-film** - The double-glass construction increases the module's weight to 23.5 kg, while comparable glass-transparent backsheet modules (e.g., Lina Energy LEPV 132) weigh approximately 20-21 kg. When installing 10 kWp (~23 modules), the total roof load increases by approximately 57-69 kg - this may require additional static assessment for older roof structures. - **Performance lower than the segment leader** - The Luxor Solar ECO LINE N-TYPE TOPCON NON-REFLECT solar panel achieves an efficiency of 22.86% at the same maximum power output of 440 Wp, which represents a 0.29% advantage over the METEOR (22.57%). In practice, this difference is marginal, but it can be significant in installations with limited roof space. ## About this series The AE Solar METEOR (AE CMD-108BDS) series are modules designed for real operating conditions in Poland - where stable energy output, even under cloudy skies, fog, and low light angles, is crucial. The use of **N-type TOPCon cells** helps to minimize energy losses and maintain high efficiency over a wider range of conditions, not just in ideal sunlight. The **bifacial** design allows for the utilization of reflected light from the ground, which is important, for example, on bright roofs, membranes, gravel, or in ground-mounted installations. The AE CMD-108BDS model also features **double-glass**, which increases resistance to moisture, temperature changes, and long-term environmental exposure, while also supporting the longevity of the module. Thanks to **half-cut cells**, the panel better handles partial shading and reduces the risk of yield drops in more complex roof configurations. This is a sensible choice for homes, businesses, and projects where durability, predictable performance, and high output are priorities. ## Notable figures - At 21.5% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - 215.4 W/m² power density is 4.8 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - requires larger installation area - 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 warranty period for AE Solar METEOR AE CMD-108BDS panels? The AE Solar METEOR (AE CMD-108BDS) series offers a 30-year product warranty and a 30-year performance warranty. After 30 years, the panel should maintain at least 87% of its nominal power. This is one of the longest standard warranties available on the market, which is particularly important when calculating the return on investment for residential and commercial installations. ### Does the AE Solar METEOR CMD-108BDS panel perform well in cloudy conditions and under typical Polish weather conditions? Yes. The N-type TOPCon technology used in the METEOR series is characterized by a low temperature coefficient of -0.29%/°C, as well as improved performance in low-light conditions compared to older PERC cells. This means that the panels maintain a reasonable energy yield on cloudy days, in foggy conditions, and with low solar angles during the winter - conditions typical for Poland for a large part of the year. ### What does it mean that the AE Solar METEOR panel is bifacial, and is it practical for a standard roof? "Bifacial" means that the panel generates electricity from both sides - the front and the back. On bright surfaces, such as white roof membranes, gravel, or concrete, the back side can add a few to several dozen percent of additional energy. On a typical dark roof, the effect is smaller, but still present. Double-glass further protects the cells on both sides, extending the lifespan of the module. ### What are the dimensions and weight of the AE Solar METEOR AE CMD-108BDS panel - will it fit on my roof, and is it difficult to install? The panel has dimensions of 1721 × 1133 × 30 mm and weighs approximately 23.5 kg in the bifacial version with double glass. These are standard dimensions for a 440W half-cut class module, suitable for standard mounting systems. The weight is slightly higher than that of panels with single glass, so when installing on steep roofs, it's important to have a qualified installation team. ### Is AE Solar a reliable manufacturer - where is it located and is it a Tier 1 supplier? AE Solar is based in Germany and has been operating in the photovoltaic market since 2003. The manufacturer holds a Tier 1 status, which means a positive assessment from Bloomberg NEF regarding its financial credibility and production quality. This translates to a lower risk for the buyer that the manufacturer may cease to exist during the term of the 30-year warranty. ### How does the half-cut technology used in the METEOR series differ from standard cells, and is this a significant factor when considering partial shading? Half-cut cells are cells that have been cut in half, which reduces internal current losses and improves the panel's performance when partially shaded, for example, by a chimney, antenna, or tree. The METEOR series utilizes 108 such N-type TOPCon cells. In practice, this means that partial shading of one part of the panel does not completely eliminate energy production from the remaining part - a significant advantage on complex roofs. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmd-108bds-420w-440w-ver25-4-1-8f73d380c12e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [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 | +45 W, lighter, +2.3 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, cooler, +2.3 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +50 W, +2.2 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +2.1 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +40 W, lighter, +2.1 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +2.1 pp | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -140 W, -7.2 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -135 W, -6.9 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -130 W, -6.7 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -125 W, -6.4 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -120 W, -6.1 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +75 W, cooler, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +85 W, cooler, +3.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +70 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/ae-solar-cmd-108bds-420w 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.
