This translates to improved access to project financing and increased trust from banks when installing commercial projects. - **Efficiency of up to 22.57% compared to the class average** - The maximum efficiency of 22.57% places this series above the KDM Kingdom Solar (22.5%) and Lina Energy LEPV 132 Ultra Premium (22.37%) models among direct comparable products. Higher power output per square meter is particularly important when roof space is limited. - **30-year product and performance warranty** - Both the product warranty and the power warranty last for 30 years – 5 years longer than the standard 25-year terms offered by most Tier-1 manufacturers (Trina, JA Solar, LONGi). This provides lower residual risk when modeling Net Present Value (NPV) for long-term projects. - **N-type TOPCon technology: elimination of LID and low Pmax/°C** - N-type TOPCon cells completely eliminate the LID (Light-Induced Degradation) phenomenon, which is characteristic of older P-type PERC cells. The lower temperature coefficient (typically -0.30%/°C for TOPCon vs -0.35%/°C for PERC) translates to a significantly higher energy yield during the summer months. - **Bifacial Double Glass: An added advantage and enhanced durability** - The dual-layer construction eliminates the use of a back EVA film that is susceptible to UV and moisture degradation, providing improved mechanical strength and resistance to ammonia and salt. Bifacial energy generation from the back side typically generates an additional 5–15% of energy, depending on the albedo of the surface and the mounting angle. ## Cons - **Performance lower than Luxor ECO LINE N-TYPE** - The maximum efficiency of 22.57% is 0.29% lower than the Luxor Solar ECO LINE N-TYPE NON-REFLECT (22.86%) in the same 440 Wp power range. In large rooftop installations with precise layout designs, this difference can translate into 1-2 additional modules while maintaining the same system power. ## About this series The AE Solar Horizon CMD-108BDS series redefines performance standards through the use of advanced **N-type TOPCon** cells, which minimize energy losses and ensure excellent long-term operational stability. The **Bifacial Double Glass** design allows for the efficient use of light reflected from the ground, significantly increasing the total energy yield compared to traditional monofacial modules. This solves the problem of limited installation space, offering higher power per square meter and better resistance to degradation caused by external factors. Thanks to the total elimination of the LID phenomenon and a low temperature coefficient, these panels maintain high efficiency even on hot days, making them an ideal choice for demanding prosumer and commercial installations. What distinguishes the Horizon series from the competition is its exceptional **mechanical strength** combined with an aesthetic design that fits perfectly into modern architecture. Double glass not only protects the cells from moisture and corrosion but also guarantees a significantly longer system lifespan, realistically reducing operating costs. It is a solution dedicated to conscious investors seeking a **maximum return on investment** and a technological advantage that standard older-generation modules cannot provide. ## Notable figures - At 22.6% efficiency, this panel is 0.6pp above typical \*\*TOPCon 400-450W\*\* modules (median: 22.0%) - At 225.7 W/m² power density, this panel generates 5.5 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - 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 on AE Solar Horizon CMD-108BDS panels? The Horizon CMD-108BDS series comes with a 30-year product warranty and a 30-year warranty on power output. The manufacturer guarantees that after 30 years of operation, the panel's power output will not fall below 87% of its nominal value. This is one of the longest warranties available on the market, reflecting the manufacturer's high confidence in the durability of these modules. ### What does the TOPCon technology mean in the AE Solar Horizon CMD-108BDS solar panels, and is it worth paying extra for? TOPCon (Tunnel Oxide Passivated Contact) refers to N-type solar cells, which offer higher efficiency and lower degradation compared to older PERC cells. In practice, the Horizon CMD-108BDS achieves an efficiency of up to 22.57% and a temperature coefficient of only -0.29%/°C. This translates to lower power losses in the summer and more power generated throughout the year. For most installers, the added cost is justified by the higher energy yield. ### Do bifacial (two-sided) AE Solar Horizon CMD-108BDS panels actually produce more energy than monofacial panels? Yes, the Bifacial Double Glass design allows the back side of the module to absorb light reflected from the ground, roof, or surrounding environment. Depending on the albedo (reflectivity) of the surface (e.g., light gravel, reflective membrane, snow), the energy generated from the back side typically ranges from 5–15% higher than that of a single-sided module. This effect is particularly noticeable in ground-mounted and flat-roof installations with light-colored surfaces. ### Are AE Solar Horizon CMD-108BDS panels suitable for mounting on a pitched roof with tiles or metal? Yes. The Horizon CMD-108BDS modules have dimensions of 1721 x 1133 x 30 mm and weigh 23.5 kg, which meets the standard specifications for roof installations. The double-pane glass provides protection against hail of Class 4, which is particularly important for pitched roofs. The panel is compatible with typical mounting systems for both ceramic tiles and corrugated steel. ### Is AE Solar a reputable manufacturer of solar panels? AE Solar is a German-based manufacturer classified as Tier 1 by Bloomberg NEF, indicating the product's bankability and the company's financial credibility. The panels are sold on European markets and are available through authorized distributors. A 30-year product and performance warranty confirms the manufacturer's commitment to the long-term quality of its modules. ### How do AE Solar Horizon CMD-108BDS panels perform on hot days or at high temperatures? Thanks to the temperature coefficient of -0.29%/°C, the Horizon CMD-108BDS series loses less power with increasing temperature compared to typical PERC modules (-0.34 to -0.40%/°C). The modules operate in a range of -40°C to +85°C and are resistant to LID (Light-Induced Degradation). In practice, on a very sunny roof, this means a significantly higher annual energy yield compared to older generations of panels. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-cmd-108bds-horizon-420w-440w-ver25-12-1-65f2c4875433.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +1.9 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +1.9 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.7 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.7 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +1.7 pp | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -160 W, -8.2 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -155 W, -8.0 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -150 W, -7.7 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -145 W, -7.4 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -140 W, -7.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +1.9 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-cmd-108bds-440w 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.
