A lot of power per square metre, at low weight: 475 W and 23.8% efficiency at only about 21 kg, suitable including for lightweight roofs.
In this model too, all the electrical contacts are on the back of the cell, so the front is uniform, without metal lines, and the panel copes better when part of it falls into shade. The difference from the versions with glass on both faces is the construction: here there is a single sheet of tempered glass, thicker, at the front, and a protective film on the back. That makes it a few kilograms lighter and simpler to lift onto the roof.
On the same overall size of 1757 x 1134 x 30 mm, i.e. about 2 sq m, the panel delivers 475 W and 23.8% efficiency, one of the highest power densities in the residential 54-cell format. As a guideline, 11 panels mean around 5.2 kWp, and 21 panels approximately 10 kWp over about 42 sq m (calculated from power and dimensions). It weighs only about 21 kg, compared with 24 kg for the double-glass version, so it loads the structure of lightweight roofs, of sheet metal or sandwich panel, less. On scorching days it loses 0.26% of its power for each degree above the reference temperature, and the warranty is 15 years on the product, extendable to 25, plus 30 years on performance.
At STC: Vmp 34.80 V, Imp 13.66 A, Voc 41.24 V, Isc 14.35 A, 108 N-type ABC cells (6 x 18), 3.2 mm tempered front glass and backsheet, black anodised aluminium frame. IP68 junction box with 3 bypass diodes, original MC4 connectors, 4 sq mm cable with 1200 mm on the positive side. Coefficients -0.26 %/°C for Pmax, -0.22 %/°C for Voc and +0.05 %/°C for Isc; maximum system voltage 1500 V DC; mechanical load 5400 Pa front / 2400 Pa back; fire class IEC C. It is used with inverters of 3-20 kW.
Suitable for a house with a small or lightweight roof (sheet metal, sandwich panel), where you need a lot of power on few square metres, without loading the structure.

Specifications confirmed from the manufacturer's datasheet
AIKO-A475-MAH54Mw is the mono-glass (Mw) version of the Neostar 2P54 series, with 108 N-type ABC cells in a 6 x 18 configuration. On the same overall size of 1757 x 1134 x 30 mm as the dual glass versions, the module reaches 475 W and 23.8% module efficiency - one of the highest power densities for the residential 54-cell format.
The parameters at STC are Vmp 34.80 V, Imp 13.66 A, Voc 41.24 V and Isc 14.35 A. The construction uses 3.2 mm tempered glass at the front and a backsheet, a black anodised aluminium frame and an IP68 junction box with 3 bypass diodes; the connectors are original MC4, and the 4 sq mm cable has 1200 mm on the positive side. Being mono-glass, the module weighs only about 21 kg, so it places a small load on lightweight roofs and is simpler to install than a 24 kg dual glass one.
The temperature coefficients are -0.26 %/degree C for power, -0.22 %/degree C for Voc and +0.05 %/degree C for Isc, and the back-contact technology without a front grid brings good tolerance to partial shading. The module withstands 5400 Pa of front load and 2400 Pa on the back, a maximum system voltage of 1500 V DC and has fire class IEC C. It is used in residential and small commercial systems, with inverters of 3-20 kW.
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.
