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. - **ABC Technology – No Front Shadows** - 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. - **30-year power guarantee, degradation less than 0.35% per year** - 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. - **Dual-glass construction – low degradation and environmental resistance** - 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 – a pioneer in mass production of ABC, ranked as a Tier 1 company by BNEF** - 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. ## Cons - **Premium price ~25–30% above standard tier-1 prices** - 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. - **Load of 33 kg – structural requirements for the roof** - 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. - **15-year product warranty – below premium-level standards** - 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. ## About this series 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. ## Notable figures - Efficiency of 24.4% matches the \*\*Back Contact 650-700W\*\* median - At 244.3 W/m² power density, roof space requirements are typical for \*\*Back Contact 650-700W\*\* panels - At -0.26%/°C, hot weather performance is typical for \*\*Back Contact 650-700W\*\* panels - In the top 1% for efficiency among all Back Contact panels ## Questions ### What distinguishes the Back Contact (ABC) technology in AIKO Stellar 3N+72 panels from standard monocrystalline panels? In the ABC (All Back Contact) technology, all electrical contacts have been moved to the back of the cell – the front surface has no current-collecting strips. This allows more light to directly reach the active surface of the cell, resulting in higher efficiency (up to 25%) and better performance with diffuse light. Standard monocrystalline panels with visible metal strips simply lose some of their active surface area to these components. ### What is the maximum power output and efficiency of the Aiko Stellar 3N+72 (Aiko-A-MDE72Dw) solar panels? The AIKO Stellar 3N+72 series achieves a peak power output of up to 675 Wp with a module efficiency of 25%. This is one of the highest results among commercially available panels in 2025. The module has dimensions of 2382 × 1134 × 30 mm and weighs approximately 33 kg, which, at this power output, provides a very favorable power density per square meter. ### What warranty does the Aiko Stellar 3N+72 panel cover, and what specific benefits does it offer? The manufacturer provides a 15-year product warranty (materials and workmanship) and a 30-year linear power warranty. Degradation is very low: less than 1% in the first year and no more than 0.35% per year in subsequent years. After 30 years, the module should maintain at least 88.85% of its nominal power. This data allows for precise planning of return on investment throughout the entire lifespan of the product. ### Do the Aiko Stellar 3N+72 panels perform well in cloudy and low-light conditions? Yes. The Back Contact technology eliminates shading caused by front rails, and N-type (ABC) cells have a lower temperature coefficient for Pmax, of only -0.26%/°C. Both of these factors improve performance in diffusion-limited conditions – a typical scenario in Poland for a significant portion of the year. The dual-glass construction further minimizes the risk of microcracks, which could reduce energy production after several years of use. ### Are Aiko Stellar 3N+72 panels suitable for large-scale solar farms and industrial installations? This is the primary application of this series. High individual power output (up to 675 Wp) means fewer modules and cabling per megawatt of installed power, which reduces BOS (Balance of System) costs and simplifies logistics. Low degradation and a long power warranty (30 years) also make project financing and LCOE (Levelized Cost of Energy) forecasting easier. The dual-glass design also provides the mechanical durability required in field conditions for decades. ### Is AIKO a reputable manufacturer, and is the Stellar 3N+72 series still available? AIKO Solar is a Chinese manufacturer classified as Tier 1 by independent industry agencies, indicating financial stability and a confirmed quality control process. The Stellar 3N+72 (AIKO-A-MDE72Dw) series is active and available on the European market. The manufacturer's datasheet was updated in February 2025, confirming the ongoing production of this product line. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/stellar-3n-plus-72-aiko-a-mde72dw-650w-675w-b101725b0e4c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -10 W, lighter, +0.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +20 W, lighter, +0.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +15 W, lighter, +0.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -15 W, lighter, +0.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +40 W, heavier, +0.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +35 W, heavier, +0.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +10 W, lighter, +0.4 pp | | [AIKO AIKO-G625-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g625-mch72mw) | 625 W | -35 W, lighter, -1.3 pp | | [AIKO AIKO-G630-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g630-mch72mw) | 630 W | -30 W, lighter, -1.1 pp | | [AIKO AIKO-G635-MCH72Dw](https://comparepv.com/panel/aiko-aiko-g635-mch72dw) | 635 W | -25 W, -0.9 pp | | [AIKO AIKO-G640-MCH72Dw](https://comparepv.com/panel/aiko-aiko-g640-mch72dw) | 640 W | -20 W, -0.7 pp | | [AIKO AIKO-G645-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g645-mch72mw) | 645 W | -15 W, lighter, -0.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +10 W, lighter, +0.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +10 W, +0.4 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a660-mde72dw Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
