Bifacial with a very active rear side: 650 W, 24.1% efficiency, 75% bifaciality, fire class A and hail testing at 25 mm at 23 m/s.
This is a panel that produces power on both faces, with one particularity: its rear side is unusually productive for this category. The cells are held between two sheets of glass and have all their electrical contacts on the back, so the front stays clean, without metal lines covering the light. It was also hail tested, with 25 mm balls launched at 23 m/s, that is around 83 km/h (calculated equivalent).
The panel measures 2382 x 1134 x 30 mm, that is about 2.7 sqm, and weighs 32.5 kg. As a guideline, 100 panels mean 65 kWp over about 270 sqm of module surface (calculated from power and dimensions). The bifaciality factor of 75% ± 5% is above the average of bifacial modules with 144 cells and shows that the rear side can add, under good reflected light conditions, up to approximately three quarters of the front side production; the gain depends on the ground albedo and on the mounting height. It has fire class A, the best one, and withstands 5400 Pa pressure on the front and 2400 Pa on the rear.
At STC: 650 W, Voc 49.70 V, Vmp 40.68 V, Isc 16.64 A, Imp 15.98 A, 132 N-type ABC cells (6 x 22), front efficiency 24.1%. Compared with the 144-cell versions, this configuration works at lower voltage and higher current, which changes string sizing and fuse selection. Laminate of coated semi-tempered double glass, 2.0 + 2.0 mm, IP68 junction box with 3 bypass diodes, MC4 / MC4-EVO2A connectors with 4 sqmm cable and 400 mm; coefficients -0.26 %/°C for Pmax, -0.22 %/°C for Voc, +0.05 %/°C for Isc; maximum system voltage 1500 V DC. Note: for the code A650-GRH66Dw there are several datasheet revisions, with small differences in Vmp/Imp; the values above come from a complete authorised distributor datasheet.
Suitable for ground-mounted parks, carports and agrivoltaic structures, especially in areas with hail risk or where the project requires fire class A.

Series-level specifications — valid for the product family
AIKO-A650-GRH66Dw is a glass-glass bifacial module from the AIKO platform with 132 N-type ABC cells in a 6 x 22 configuration, in a 2382 x 1134 x 30 mm format. At 650 W this gives a front efficiency of 24.1%, and the mass is about 32.5 kg.
The electrical parameters at STC are Voc 49.70 V, Vmp 40.68 V, Isc 16.64 A and Imp 15.98 A. Compared with the 144-cell versions, this configuration works at lower voltage and higher current, which influences string sizing and fuse selection. The laminate uses coated semi-tempered double glass, 2.0 + 2.0 mm, an anodised aluminium frame and an IP68 junction box with 3 bypass diodes; the connectors are MC4 / MC4-EVO2A, with 4 sqmm cable 400 mm long. The declared bifaciality factor is 75 +/-5%, above the average of bifacial modules with 144 cells.
The temperature coefficients are -0.26 %/deg C for power, -0.22 %/deg C for Voc and +0.05 %/deg C for Isc. The module has fire class A, withstands 5400 Pa on the front and 2400 Pa on the rear and was tested against hail of 25 mm at 23 m/s. The maximum system voltage is 1500 V DC. Note: there are several datasheet revisions for the code A650-GRH66Dw (the 66-cell Stellar series), with small differences in Vmp/Imp; the values above come from a complete authorised distributor datasheet.
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.
