The Aiko Neostar 2S+ AIKO-A465-MAH54Db is a 465W full-black dual-glass solar panel built on N-type ABC (All Back Contact) cell technology. With every electrical contact moved to the rear of the cell, the front surface is completely free of busbars and grid lines, giving a clean, uniform black finish and a module efficiency of 23.3% from a compact 1757 x 1134 x 30 mm footprint.
Two sheets of 2.0 mm coated semi-tempered glass replace the conventional backsheet, improving resistance to moisture ingress and micro-cracks, while the black anodised aluminium frame keeps the look consistent across the whole array. The cell layout is designed for partial shading optimisation and a low -0.26%/°C power temperature coefficient, so output holds up better on hot summer roofs and where chimneys, dormers or trees cast part-shade.
Backed by a 25-year product warranty and a 30-year linear performance warranty with ≤1% first-year degradation and ≤0.35% per year thereafter, it suits domestic roofs, carports and commercial installations where long-term yield, appearance and roof space all matter.

Installation and safety
Installation must be carried out by a qualified installer in line with BS 7671 and the manufacturer's installation manual. Do not drill the frame, and keep a minimum 10 cm gap between the module frame and the roof surface for ventilation. Frames must be earthed, and rooftop installs should be checked for structural suitability first.
Compatibility and weight
Dual-glass construction makes this a heavier panel at 24.5 kg. Confirm roof loading and mounting-rail suitability before ordering. Clamp mounting on the long frame is rated +5400 Pa / -2400 Pa; use at least four clamps per module (six where wind or snow loads are high). Panels within one string must be the same model and power class.
Strings and voltage
Voc is 41.12 V at STC and rises in cold weather (Voc temperature coefficient -0.22%/°C). Always size strings against the lowest expected site temperature so the inverter's maximum input voltage is never exceeded.
Key features
N-type ABC cell technology
All contacts sit on the rear of the cell, removing front busbars so more of the surface collects light and the panel looks uniformly black.
Dual-glass construction
2.0 + 2.0 mm coated semi-tempered glass improves resistance to moisture, micro-cracks and long-term material fatigue.
Partial shading optimisation
The cell layout and 3 bypass diodes help limit losses when a shadow covers only part of the panel.
Low temperature coefficient
Pmax coefficient of -0.26%/°C keeps more output on hot roofs than typical PERC modules.
30-year linear performance warranty
Guaranteed degradation of ≤1% in year one then ≤0.35% per year, with a 25-year product warranty.
Robust and weather-tested
Rated for +5400 Pa front / -2400 Pa rear static load, IP68 junction box, and 35 mm hail at 27.2 m/s.

Frequently asked questions
What does ABC (All Back Contact) technology mean?
In an ABC cell every electrical contact is on the rear surface, so the front has no busbars or grid lines. That leaves more active area to absorb light and gives the panel a uniform, clean black appearance.
Is this panel bifacial?
The manufacturer datasheet for the AIKO-A465-MAH54Db does not specify bifacial rear-side power gain, so it should be treated as a dual-glass panel rated on its front-side output. Design yield calculations around the 465W STC figure.
What warranty does it come with?
A 25-year product warranty and a 30-year linear performance warranty. Degradation is guaranteed at ≤1% in the first year and ≤0.35% per year from year 2, leaving 88.85% of rated power at year 30.
How should it be mounted?
Clamp mounting on the long frame is rated +5400 Pa / -2400 Pa, with the clamp centre positioned 295 to 395 mm from the module end. Use at least four clamps per panel, and six where wind or snow loads are high. Do not drill the frame.
Can it be mixed with other Aiko models in one string?
No. Modules with different electrical performance must not share a string, so keep a string to a single model and power class.
Is it suitable for UK roofs and carports?
Yes, subject to a structural check. It is a compact 1757 x 1134 mm panel with a black frame and no front grid lines, which suits visible domestic roofs and carports, but at 24.5 kg the roof and rail loading should be confirmed by your installer.
