A fully black panel, with no metal lines on the front, which handles partial shading better. 460 W over 2 sqm, about 23.1% efficiency and only -0.26%/°C loss in a heatwave.
On the front of this panel you cannot see the thin metal lines that normally cross the cells: all the electrical contacts are moved to the back, a technology called ABC (All Back Contact). The result is a uniform surface, more room to catch light and a better behaviour when part of the panel falls into shade - from a chimney, an antenna or a branch. The cells sit between two sheets of glass, as in a thin window, which protects them from cracks and from the weather.
The panel measures 1757 x 1134 mm, that is about 2 sqm, and weighs 24.2 kg; as a guide, 11 pieces mean around 5 kWp over approximately 22 sqm, and 22 pieces around 10 kWp over approximately 44 sqm (calculated from power and dimensions). The efficiency of about 23.1% is among the highest in the format for houses, so you get more kilowatts out of the same roof. On very hot days it loses 0.26% of its power for every degree above the reference temperature, less than an ordinary TOPCon panel, which loses 0.29%. The declared ageing is below 1% in the first year and below 0.35% per year afterwards, and the warranty is 15 years on the product, extendable to 25, plus 30 years on performance.
Configuration of 108 N-type ABC cells (6 x 18), glass-glass laminate 2.0 + 2.0 mm, 30 mm black anodised aluminium frame. Temperature coefficients -0.26 %/°C for Pmax and -0.22 %/°C for Voc, maximum system voltage 1500 V DC, mechanical load 5400 Pa on the front and 2400 Pa on the back. Stäubli MC4-EVO2 connectors with 1200 mm cables, useful for interconnection in long rows. Note: the individual electrical values (Voc/Isc) of the 460 W version have not been confirmed on a dedicated datasheet; the data above are those valid for the whole Neostar 2P+54 Dual-Glass series.
Suitable for a house whose roof has partial shading from chimneys, antennas or trees, or for someone who wants a uniform appearance and high yield over a small area.

Series-level specifications — valid for the product family
AIKO-A460-MAH54Dw is part of the Neostar 2P+54 Dual-Glass series (455-475 W) and uses AIKO's own ABC (All Back Contact) technology: all the electrical contacts are moved to the back of the cell, so the face exposed to the sun has no busbars or metal fingers. The result is a larger active surface, a uniform appearance and a high yield per square metre - 460 W on a module of 1757 x 1134 mm means about 23.1% module efficiency.
The cells are N-type ABC, 108 pieces in a 6 x 18 configuration, encapsulated between two 2.0 mm glass sheets in a 30 mm black anodised aluminium frame. The temperature coefficient of power is -0.26 %/grad C, and that of open-circuit voltage -0.22 %/grad C, among the best on the market - the module loses less power on scorching days than an ordinary TOPCon (-0.29 %/grad C). The ABC architecture also offers a good tolerance to partial shading: when part of the module is shaded, the drop in production is smaller than with conventional modules.
The glass-glass structure and the absence of the front grid reduce the risk of microcracks and hot spots, and the manufacturer declares degradation below 1% in the first year and below 0.35% per year afterwards. The module withstands 5400 Pa front load and 2400 Pa on the back, has a maximum system voltage of 1500 V DC and Staubli MC4-EVO2 connectors with 1200 mm cables, which simplifies interconnection in long rows. Note: the individual electrical values (Voc/Isc) of the 460 W version have not been confirmed on the dedicated datasheet; the data above are those valid for the whole Neostar 2P+54 Dual-Glass series.
More energy from the same roof area: 600 W from a single module, at 23.2% efficiency, with the contacts moved to the back for a fully active front face.
Fewer parts and faster installation for the same power: 615 W per module, at 23.8% efficiency, in a panel of 27 kg and 2278x1134x30 mm.
455 W and 22.8% efficiency in a 21.5 kg panel, with cells without metal contacts on the front and low losses in heat.
The front of the panel has no metal stripes: 450 W, 22,6% efficiency and only 21,5 kg, with good behaviour under partial shading.
