A gap of roughly 3 percentage points means a materially smaller array footprint for the same installed power. - **Quarter-cut N-type TOPCon cells** - Quarter-cut cell segmentation further reduces resistive losses compared to common half-cut designs, while N-type TOPCon delivers lower LID/LeTID degradation and better high-temperature performance than the older PERC cells used by the peer comparables. - **Bifacial double-glass construction** - Double-glass bifacial design captures additional energy from rear-side reflected light without increasing installation footprint, which is particularly relevant for utility-scale PV farms and large commercial installations optimizing LCOE. - **30-year power warranty, Tier-1 manufacturer** - A 30-year performance warranty paired with a 15-year product warranty exceeds the market standard (typically 25/12 years). AE Solar is a German Tier-1, BNEF-bankable manufacturer operating since 2003, further reducing project financing risk. - **Mechanically robust anodized aluminum frame** - A solid anodized aluminum frame and high declared snow and wind load resistance make the series suitable for demanding mounting conditions, including the Polish climate. ## Cons - **Limited public documentation availability** - A direct datasheet for the CMEQ-66BDS variant could not be located on AE Solar's official resources (api.ae-solar.com) - only datasheets for related Meteor series (CMER-96BDS 440-460W, CMER-132BDS 610-630W) are indexed, making independent verification of parameters harder for integrators and investors. ## About this series The METEOR CMEQ-66BDS series brings **quarter-cut cell technology** to the market, reducing resistive losses even further than the now-common half-cut design and translating into higher energy yield from every square meter of roof or ground-mounted array. The modules rely on next-generation **n-type TOPCon cells**, delivering stronger performance under diffuse light and at elevated operating temperatures - a real advantage in Poland's variable-irradiance climate. Thanks to a **bifacial double-glass construction**, the panels also capture reflected light on the rear side, boosting total system output without increasing the installation's footprint. This makes the series particularly attractive for utility-scale solar farm developers and large commercial installations, where every fraction of efficiency matters and **LCOE** optimization is a priority over decades of operation. A rugged anodized-aluminum frame combined with high snow and wind load resistance makes the series suitable for demanding mounting conditions as well. A long-term **30-year performance warranty** further protects the investment, setting CMEQ-66BDS apart from monofacial modules and older PERC-generation competitors. ## Notable figures - At 24.2% efficiency, this panel is 1.9pp above typical \*\*TOPCon 650-700W\*\* modules (median: 22.4%) - At 242.5 W/m² power density, this panel generates 18.8 W/m² more per unit area than \*\*TOPCon 650-700W\*\* median (223.7 W/m²) - At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions - 32.2 kg weight - 2.4 kg lighter than \*\*TOPCon 650-700W\*\* median (34.6 kg), reducing installation effort - Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof ## Questions ### How does quarter-cut cell technology in AE CMEQ-66BDS panels differ from popular half-cut cells? Quarter-cut cells are cut into four pieces, twice as many as half-cut. Shorter current paths mean lower resistive losses and reduced module heating, resulting in higher energy yield from the same surface area. Additionally, smaller cell fragments handle partial shading better, for example from chimneys or trees. ### What warranty comes with AE CMEQ-66BDS panels? AE Solar provides a 15-year product warranty and a 30-year power output warranty. This means the manufacturer guarantees a defined performance level for three decades, one of the longer terms on the market, setting this series apart from older PERC-based modules. ### Do AE CMEQ-66BDS bifacial panels require special installation? To fully exploit the bifacial potential, panels should be mounted on racking that elevates them above the ground, paired with a light, reflective surface (such as white gravel or reflective sheeting), especially in ground-mounted installations. On dark roof surfaces, the rear-side gain will be lower, but the panel still performs as a standard monofacial module. ### What is the maximum power output of the AE CMEQ-66BDS panel and what installations is it suited for? CMEQ-66BDS series panels reach up to 670 Wp, placing them among high-power modules. Due to their large format and high wattage, the series is particularly attractive for utility-scale solar farms and large commercial or industrial installations, where minimizing module count and optimizing LCOE are priorities. ### Do n-type TOPCon cells in AE CMEQ-66BDS panels perform better than classic PERC cells in Poland's climate? Yes, TOPCon cells have a lower temperature coefficient and perform better under weak, diffuse light conditions than PERC. In Poland's climate, with frequent cloudy days and temperature swings, this translates into more stable energy production throughout the year, especially in spring and autumn. ### Is AE Solar, the manufacturer of CMEQ-66BDS panels, a trustworthy company? AE Solar is a Tier 1 manufacturer headquartered in Germany, indicating strong financial standing and bankability for projects using its modules. Tier 1 status matters for financing large installations, as banks and investors more readily accept equipment from manufacturers with a proven track record and supply stability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/AE_CMEQ_66_BDS_650_W_670_W_Ver26_9_1_d309c28f93-759ff3916818.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Lighter, +0.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +25 W, lighter, +0.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +20 W, lighter, +0.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -10 W, lighter, +0.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +45 W, heavier, +0.8 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +20 W, +0.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +40 W, heavier, +0.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +15 W, lighter, +0.6 pp | | [AE Solar AE CMER-88BD-410](https://comparepv.com/panel/ae-solar-ae-cmer-88bd-410) | 410 W | -245 W, hotter, -9.1 pp | | [AE Solar AE CMER-88BD-415](https://comparepv.com/panel/ae-solar-ae-cmer-88bd-415) | 415 W | -240 W, hotter, -8.9 pp | | [AE Solar AE CMER-88BD-420](https://comparepv.com/panel/ae-solar-ae-cmer-88bd-420) | 420 W | -235 W, hotter, -8.7 pp | | [AE Solar AE CMER-88BD-425](https://comparepv.com/panel/ae-solar-ae-cmer-88bd-425) | 425 W | -230 W, hotter, -8.5 pp | | [AE Solar AE CMER-88BD-430](https://comparepv.com/panel/ae-solar-ae-cmer-88bd-430) | 430 W | -225 W, hotter, -8.3 pp | | [AE Solar CMER-132BDS-610](https://comparepv.com/panel/ae-solar-cmer-132bds-610) | 610 W | -45 W, hotter, -1.6 pp | | [AE Solar CMER-132BDS-615](https://comparepv.com/panel/ae-solar-cmer-132bds-615) | 615 W | -40 W, hotter, -1.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +15 W, lighter, +0.6 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-cmeq-66bds-655 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.
