Light for its output, no clear weak spot
The AE Solar METEOR CMD-108E series has been designed for stable and predictable energy production under real roof conditions, even when clouds, light fog, or increased sunlight occur. A key advantage is the N-type TOPCon cell technology, which supports high efficiency and helps to minimize performance degradation over time. This is a choice for investors who expect not only a good initial performance but also a long period of reliable operation.
The CMD-108E variant focuses on a monofacial design, making it easy to integrate with typical roof installations in homes and businesses, without complicating the project due to reflection from the ground. The series also features good performance in low light conditions and resistance to degradation, which translates to more consistent energy production from season to season. An additional advantage is the ability to aesthetically match the building's facade through different finishing options. This is a solution for those who want to combine affordability, reliability, and aesthetics in their solar installations.
Ranking
Signals from the data
Residential and commercial.
Top 14% of the TOPCon 400-450 W segment, against a median of 51.5.
N-type TOPCon cells exhibit a Pmax temperature coefficient of -0.29%/°C, which is a significant advantage over standard PERC modules (-0.35%/°C). In practice, this translates to lower power losses on hot days and a realistically higher annual energy yield in a central European climate.
The manufacturer guarantees a degradation of ≤1% in the first year and ≤0.4%/year in years 2-30, with a final retention of ≥87.4% of the nominal capacity. These are more favorable conditions than the industry standard of 25 years used by most comparable manufacturers (e.g., Luxen, ZNShine), which translates to a longer, more economically justifiable period of operation.
The maximum efficiency of the series is 22.31%, which places it slightly above its direct counterparts: Luxen LUXPOWER N5 (22.28%), ZNShine ZXM7-UHLDD108 (22.28%), and Solitek SOLID Blackstar (22.27%). Higher efficiency translates to greater power output from the same roof area.
The module has a fire resistance rating of Class A according to IEC 61730, as well as a hail resistance rating of Class 4, which is a requirement of many insurance companies and local building codes for installation on the roofs of residential and commercial buildings. This eliminates potential obstacles in obtaining permits.
AE Solar (headquartered in Germany, since 2003) has been listed in BNEF's Tier 1 rankings since the 16th edition and, in the 2024 BNEF report, ranked 18th out of 67 evaluated manufacturers, as the only European producer. The bankability has increased from 26% (2023) to 50% (2024), making it easier for independent commercial banks to finance projects.
The CMD-108E variant is a monofacial design - it does not utilize reflection from the ground, which in bifacial modules (such as the CMD-108BDE from the same series) can increase energy yield by 5-15% on a light surface (snow, light gravel, concrete). For ground-mounted or flat-roof installations with appropriate albedo, this represents a real loss of energy production.
- At 22.1% efficiency, this panel is on par with typical TOPCon 400-450W modules
- At 220.5 W/m² power density, roof space requirements are typical for TOPCon 400-450W panels
- Temperature coefficient of -0.29%/°C matches the TOPCon 400-450W median
- Weight of 20.3 kg (1.7 kg below TOPCon 400-450W median of 22.0 kg) allows easier transport and roof mounting
- In the top 45% for efficiency among all TOPCon panels
