Solid all-round for its segment
AIKO Stellar 3N+72 (AIKO-A-MDE72Dw) are dual-glass modules designed to maximize energy yield where every square meter counts and ensure stable performance year after year. The key advantage is the back-contact cell technology (XBC/ABC) - without front busbars, limiting shading on the active surface and improving performance under weaker illumination. The dual-glass construction increases resistance to environmental factors and reduces the risk of micro-cracks, translating to more reliable energy production over the long term. This is also an excellent choice for projects where low degradation and long warranties are important, as it allows for easier financial project planning. These modules are suitable for PV farms, large industrial rooftops, and commercial investments, where lower LCOE and predictable yield along with the high-quality execution that distinguishes this series from standard bifacial dual-glass panels is crucial.

Signals from the data
Commercial, utility-scale and hot-climate.
Comparable models from this power segment (Neo Solar Power NESE, BYD AURO MSTK-33, Trina Vertex TSM-DE21) achieve a maximum efficiency of 21.73%. The MDE72Dw series outperforms them by approximately 3.2 percentage points (≈+15%), which, with the same roof area, translates into a proportionally higher yield – a significant advantage in situations where roof space is limited.
The All Back Contact design eliminates the front-side current collection rails, which reduces shading of the active area of the cell and lowers the temperature coefficient to -0.26%/°C (compared to -0.35%/°C for typical PERC). At a module temperature of 70°C, this represents an increase of approximately +1.2% in power output compared to PERC technology – a significant advantage in Central European climates.
AIKO guarantees ≥88.85% of its rated power after 30 years with an annual degradation rate of <0.35% (from the 2nd year onwards). For comparison, Trina Solar Vertex DE21 in this segment typically offers a 25-year warranty with a level of ~84.8%. A longer warranty period simplifies LCOE modeling and increases the value of project financing.
Double-pane glass eliminates the EVA backsheet as a pathway for moisture ingress, significantly reducing the risk of PID (Potential Induced Degradation) and microcracks. For solar farms and large industrial rooftops, where maintaining and replacing modules is expensive, this translates into a more predictable production curve throughout the system's lifespan.
AIKO was the first company in the world to master N-type ABC technology on an industrial scale, and is featured on Bloomberg NEF's Tier-1 list. The modules hold IEC 61215/IEC 61730 certifications and have up-to-date reports from DNV/PV Evolution Labs, which enables banks and insurers to finance commercial projects without requiring additional due diligence on the technology.
European quotations (2025) place AIKO ABC modules in the range of €180–220/piece, while comparable modules from Jinko/JA Solar cost €140–170/piece. The difference of approximately 25–30% may be difficult to justify in projects where only CAPEX/kWp is considered, rather than optimization for surface area.
With dimensions of 2382 x 1134 x 30 mm and a weight of 33 kg (dual-glass), these units are larger than typical single-glass modules in this power class (approximately 28-30 kg). When upgrading older industrial buildings, they may require an additional structural assessment and steel reinforcement, which increases the CAPEX (capital expenditure) for the installation.
The product warranty is 15 years, while REC Alpha and Maxeon offer 25-year product warranties in the premium back-contact segment. In the context of projects with a 20+ year financing horizon, this difference can be significant when assessing residual risk after 15 years.
