At its core lies **advanced n-Type TOPCon cell technology** arranged in a quarter-cut (48x4) layout, which reduces current losses and microcracking while improving the module's tolerance to partial shading. Thanks to **enhanced rear-side power generation**, these bifacial panels capture light reflected off the ground, boosting energy yield without expanding the footprint of the installation. The **black, double-glass construction** pairs a premium aesthetic with durability and strong resistance to PID corrosion, making it an appealing choice for both residential rooftop systems and commercial projects that value a uniform, all-black appearance. The module also stands out for **better performance under low-light conditions**, delivering more consistent output on overcast days, mornings, and evenings typical of the Polish climate. The combination of high efficiency, long-lasting tempered glass, and a lower LCOE means the CMEQ-48BDE series meets the needs of investors seeking **lower energy cost over the system's full lifecycle**, all backed by solid build quality and extended power and product warranties. ## Notable figures - Efficiency of 24.3% is 1.8pp above the \*\*TOPCon 450-500W\*\* median (22.5%) - At 242.9 W/m² power density, this panel generates 17.7 W/m² more per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.26%/°C vs median -0.29%/°C means ~1% less power loss at 65°C - Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof - In the top 1% for efficiency among all TOPCon panels ## Questions ### What is n-Type TOPCon technology in the METEOR CMEQ-48BDE panels, and does it offer a real advantage over classic PERC? TOPCon (Tunnel Oxide Passivated Contact) is an n-Type cell technology that adds a passivation layer on the rear side of the cell, reducing electron recombination. In practice this means higher conversion efficiency, lower power degradation over time, and better performance at high temperatures compared to older p-Type PERC panels. For investors, this translates into higher energy yield from the same roof area over the full 30-year power warranty period. ### Does it make sense to use bifacial METEOR CMEQ-48BDE panels on a single-family home roof, or only on ground-mount systems? Bifacial panels perform best where the rear side can capture reflected light, such as on freestanding structures, ground-mount systems, or flat roofs with light-colored surfaces. On a typical pitched roof, where the module sits close to the surface, the extra rear-side gain is smaller but still present thanks to reflection from tiles or metal sheeting. Even in these conditions, users gain a few extra percent of energy without increasing the installation footprint. ### How do the METEOR CMEQ-48BDE panels perform on cloudy days and in low-irradiance conditions typical of the Polish climate? Thanks to TOPCon cells and the quarter-cut (48x4) design, these modules make better use of diffuse and weak light than older technologies. Smaller cell segments reduce current losses, and the n-Type technology has a lower temperature coefficient, which helps under low irradiance and in cooler climates. As a result, energy production is more stable in the mornings, evenings, and on cloudy days, not just in full sun. ### What warranty comes with the METEOR CMEQ-48BDE panels, and what does it cover? Manufacturer AE Solar, a German tier 1 supplier, provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that after 30 years the panel should still generate the manufacturer-guaranteed percentage of its initial power output, placing it among the longer warranty periods available on the market. ### Is the double-glass construction of the CMEQ-48BDE panels more durable than a classic glass-and-backsheet module? Yes, the double-glass construction replaces the rear backsheet with tempered glass, increasing resistance to moisture, microcracks, and PID (Potential Induced Degradation). Such a panel better withstands variable weather conditions, including hail and large temperature swings, and typically has a longer lifespan than single-glass modules. The black aesthetic also makes it well-suited for building facades and single-family home roofs. ### What maximum power output do the METEOR CMEQ-48BDE series panels reach, and who are they suited for? Modules in this series reach a maximum power of up to 485 Wp, allowing a larger system to fit on limited roof or ground area compared to lower-power panels. This makes the series well suited both for single-family homes with limited roof surface and for commercial projects where installed power per square meter and lower levelized cost of energy (LCOE) over the system's lifetime are priorities. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/AE_CMEQ_48_BDE_475_W_485_W_Ver26_9_1_9c184c9702-3e958f64645e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +25 W, cooler, +0.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +10 W, lighter, +0.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +20 W, cooler, +0.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +20 W, heavier, +0.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Lighter, +0.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +15 W, cooler, +0.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +15 W, lighter, +0.2 pp | | [AE Solar CMER-64BD-290](https://comparepv.com/panel/ae-solar-cmer-64bd-290) | 290 W | -195 W, hotter, -9.7 pp | | [AE Solar CMER-64BD-295](https://comparepv.com/panel/ae-solar-cmer-64bd-295) | 295 W | -190 W, hotter, -9.5 pp | | [AE Solar CMER-64BD-300](https://comparepv.com/panel/ae-solar-cmer-64bd-300) | 300 W | -185 W, hotter, -9.2 pp | | [AE Solar CMER-64BD-305](https://comparepv.com/panel/ae-solar-cmer-64bd-305) | 305 W | -180 W, hotter, -9.0 pp | | [AE Solar CMER-64BD-310](https://comparepv.com/panel/ae-solar-cmer-64bd-310) | 310 W | -175 W, hotter, -8.7 pp | | [AE Solar AE\_CMD-108BD-Terracotta](https://comparepv.com/panel/ae-solar-ae-cmd-108bd-terracotta) | 360 W | -125 W, hotter, -6.2 pp | | [AE Solar AE\_CMD-108BD-Emerald](https://comparepv.com/panel/ae-solar-ae-cmd-108bd-emerald) | 375 W | -110 W, hotter, -5.5 pp | | [AE Solar AE\_CMD-108BD-Blues](https://comparepv.com/panel/ae-solar-ae-cmd-108bd-blues) | 380 W | -105 W, hotter, -5.2 pp | | [AE Solar AE\_CMD-108BD-Frost](https://comparepv.com/panel/ae-solar-ae-cmd-108bd-frost) | 385 W | -100 W, hotter, -5.0 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-cmeq-48bde-485 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.
