The Aiko Neostar 2P+ 470W (Part No: AIKO-A470-MAH54Dw) is a high-efficiency N-type ABC (All-Back-Contact) monocrystalline solar module with a dual-glass, black front / white rear construction. Moving every electrical contact to the rear of the cell removes the visible front gridlines found on conventional panels, giving a clean, uniform black appearance well suited to residential rooflines while achieving up to 23.6% module efficiency.

ABC Cell Technology: With All-Back-Contact cells, both electrical contacts sit on the rear of the cell rather than the front. This removes shading from visible metal gridlines, giving a cleaner black appearance and contributing to the panel's high efficiency and improved partial-shading tolerance.
System Design Limits: Maximum system voltage is 1500V DC and maximum series fuse rating is 25A — string sizing and overcurrent protection must stay within these limits. Installation should only be carried out by qualified solar professionals following Aiko's installation guidelines and current local regulations.
All-Back-Contact Cells
Moving both contacts to the rear of each cell removes front-side gridlines, reducing shading losses and giving a cleaner, uniformly black light-capturing surface.
Dual-Glass Durability
A glass-glass build with 2.0+2.0mm semi-tempered glass improves resistance to moisture ingress and mechanical stress compared with a standard backsheet panel.
Half-Cell Shading Tolerance
108 half-cut cells limit the impact of partial shading and hotspots, helping the module maintain output even when part of the array is shaded.
Bezel-Less Black Aesthetic
A black anodised aluminium frame and black front glass give a low-profile, uniform appearance suited to visible residential rooflines.
Low Long-Term Degradation
First-year degradation is rated at ≤1%, easing to ≤0.35% annually from year 2 to 30, supporting strong energy yield over a multi-decade warranty period.
IEC Class A Fire Rating
The module carries the highest IEC fire resistance classification, an important consideration for projects with strict fire-safety requirements.

What is ABC cell technology?
ABC stands for All-Back-Contact — both electrical connections are moved to the rear of the cell, removing the visible metal gridlines on the front. This reduces shading losses on the front surface and contributes to the panel's 23.6% module efficiency.
Is this panel bifacial?
This is genuinely unclear from available sources. Some suppliers list this dual-glass "Dw" variant as bifacial with rear-side gain, but Aiko's own datasheet doesn't include a bifacial power table, and independent reviews note that most dual-glass Neostar modules are monofacial. If bifacial yield matters to your design, confirm directly with Aiko or your supplier before relying on a rear-side gain figure.
What warranty does this module come with?
Aiko provides a 15-year product warranty (extendable to 25 years), separate from a 30-year linear performance warranty guaranteeing the module's power output degrades no faster than the rated schedule over its operating life.
How does this panel handle partial shading?
The half-cell layout (108 cells, 6×18 configuration) limits how much a shaded section of the panel affects overall output, helping the module maintain better performance than a full-cell design when part of the array is shaded by chimneys, trees, or nearby structures.
What are the key system design limits for this module?
Design to a maximum system voltage of 1500V DC and a maximum series fuse rating of 25A. Installation should be carried out by a qualified solar professional in line with Aiko's installation guidance and applicable local electrical regulations.
