Its 16th consecutive appearance on the Bloomberg Tier 1 list (Q1 2025) and its headquarters in Germany translate into greater guarantee stability and service availability compared to Asian manufacturers. - **Efficiency: 22.07-22.96% - Top performer in the segment** - The CMER-108BDS series outperforms the Trina Solar Vertex Backsheet (21.2%) by 0.87-1.76 percentage points at the same power range of 490-510 Wp. This result is comparable to that of the JA Solar JAM60S40 LR (23.0%), confirming the module's position among the leading products in the 108-cell segment. - **30-year product and performance warranty** - The manufacturer guarantees a power retention rate of >87% after 30 years of operation. The industry standard for Tier-1 (JA Solar, Trina Solar) is 25 years, meaning that the CMER-108BDS offers an additional 5 years of warranty coverage - a direct improvement in the NPV (Net Present Value) of the installation, which is particularly important for commercial and prosumer installations. - **N-type TOPCon: TC -0.29%/°C, zero LID** - The temperature coefficient specified in the datasheet (-0.29%/°C) is significantly better than the typical -0.35%/°C for PERC technology. When the module is heated to 65°C (typical summer in Poland), the difference in yield is approximately 1.7% higher compared to PERC. The absence of LID (Light-Induced Degradation) eliminates the typical power loss observed in the first few weeks of operation. - **Independent quality verification - PV Magazine 5★** - The METEOR modules received a "Very Good" rating (5 stars) in the independent PV Magazine Module Test, as well as a "Top Performer" status in the Kiwa PVEL 2025 certification (according to 8MSolar Expert Review 2026), which confirms that the actual parameters meet the specifications provided in the product data sheets. ## Cons - **The double-glass module has a higher weight.** - The double-glass bifacial design weighs 23.5 kg compared to 20.3 kg for the monofacial version of the same series - a difference of 16%. When installing on older residential building roofs (e.g., wooden structures built before 1990), a roof load assessment may be required before selecting the number of modules. ## About this series The AE Solar METEOR CMER-108BDS series redefines performance standards thanks to the use of innovative **N-type TOPCon cell** technology, which ensures significantly higher energy conversion efficiency compared to traditional solutions. A key differentiator of these modules is the **bifacial Double Glass** construction, which not only increases total energy yield through light absorption from both sides but also drastically improves the panel's resistance to micro-cracks and extreme weather conditions. The application of **SMBB (Super Multi Busbar)** technology allows for more efficient current flow and better performance in low-light conditions, which is crucial in the Polish climate. These panels solve the problem of long-term performance loss, offering **exceptionally low power degradation** over time, translating into a higher return on investment for homeowners and businesses. They are an ideal choice for prosumer and commercial installations where durability and maximizing energy production from limited roof or ground areas are the priority. By choosing the METEOR series, investors receive a product with an elevated fire safety standard, which results directly from the reinforced double glass structure, outclassing standard monofacial modules in terms of lifespan. ## Notable figures - At 22.7% efficiency, this panel is on par with typical \*\*TOPCon 500-550W\*\* modules - At 227.4 W/m² power density, roof space requirements are typical for \*\*TOPCon 500-550W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #3267 out of 14129 panels for efficiency in the database ## Questions ### What is the warranty on AE Solar METEOR CMER-108BDS panels? The METEOR CMER-108BDS series is covered by both a 30-year product warranty and a 30-year performance warranty. This means that for three decades, the manufacturer guarantees that the panel will maintain a specific level of performance - significantly higher than the standard 25 years offered by most competitors. This is an exceptionally long warranty period, which directly translates into a higher return on investment. ### What does it mean that the CMER-108BDS panel is bifacial, and does this actually increase energy production? "Bifacial" refers to a panel that generates energy from both sides - the front and the back. The back side captures light reflected from the roof, ground, or other bright surfaces. In practice, this can increase the annual energy yield by 5-15% compared to a single-sided module, especially in installations on reflective surfaces or on the ground. The Double Glass construction also protects the cells from both sides, enhancing the module's durability. ### Does the AE Solar METEOR CMER-108BDS panel perform well in low-sunlight conditions, typical of the Polish climate? Yes. The N-type TOPCon technology used in the CMER-108BDS series offers lower temperature coefficients and better performance under diffused light compared to older PERC cells. Another advantage is the SMBB (Super Multi Busbar) technology, which improves current flow at lower light intensities. This translates to higher energy production on cloudy days, which are common in Poland. ### What is the maximum power output of the most powerful panel in the AE Solar METEOR CMER-108BDS series? The maximum power output of the CMER-108BDS module series is 510 Wp. This is a high power output for a 108-cell format, made possible by the N-type TOPCon technology, which achieves a conversion efficiency of over 22%. This means that even with a limited roof area, a larger total power output for the installation can be achieved, which is particularly important for roofs with a small usable surface area. ### Is AE Solar a reliable manufacturer, and is the METEOR series available in Poland? AE Solar (AE Alternative Energy GmbH) is a Tier 1 manufacturer based in Germany, which means that it is classified by independent agencies as a supplier with proven financial stability and production quality. The METEOR CMER-108BDS series is currently in production (not discontinued) and is available on the Polish market through industry distributors. The manufacturer's European headquarters facilitates warranty claims. ### What are the key differences between the AE Solar METEOR CMER-108BDS panel and older PERC panels? The main difference lies in the technology used for the cells: CMER-108BDS utilizes N-type TOPCon cells instead of P-type PERC cells. TOPCon offers a lower annual power degradation, higher module efficiency (above 22%), and better resistance to LID (Light Induced Degradation). The bifacial double glass design replaces the rear glass with glass, eliminating the risk of microcracks and increasing the fire safety rating compared to standard monofacial modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmer-108bds-490w-510w-sc-11-5-ver25-9-1-fc9ae3aba506.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.0 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.8 pp | | [AE Solar CMER-72BD-325](https://comparepv.com/panel/ae-solar-cmer-72bd-325) | 325 W | -180 W, -8.1 pp | | [AE Solar CMER-72BD-330](https://comparepv.com/panel/ae-solar-cmer-72bd-330) | 330 W | -175 W, -7.9 pp | | [AE Solar CMER-72BD-335](https://comparepv.com/panel/ae-solar-cmer-72bd-335) | 335 W | -170 W, -7.6 pp | | [AE Solar CMER-72BD-340](https://comparepv.com/panel/ae-solar-cmer-72bd-340) | 340 W | -165 W, -7.4 pp | | [AE Solar CMER-72BD-345](https://comparepv.com/panel/ae-solar-cmer-72bd-345) | 345 W | -160 W, -7.2 pp | | [AE Solar AE CMER-108BDE-490W](https://comparepv.com/panel/ae-solar-ae-cmer-108bde-490w) | 490 W | -15 W, -0.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +55 W, cooler, +2.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +45 W, lighter, +1.7 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +35 W, lighter, +1.7 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-cmer-108bds-505 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.
