650W Photovoltaic Panel AIKO Polaris 1N+ AIKO-G650-MCH72Dw N-Type Bifacial

This is a large format panel that produces current on both faces: besides direct light, it also uses the light reflected from the ground back onto the rear of the module. The cells sit between two sheets of tempered glass, and the electrical contacts are moved to the back of the cell, so the front is uniform, without metal lines stealing surface. For a ground-mounted plant this means extra energy, without occupying additional land.

The panel is 2382 x 1134 x 30 mm, that is about 2,7 sqm, and weighs around 32,3 kg, so it is handled by two people. As a guide, 100 panels mean 65 kWp over about 270 sqm of module surface (calculation from power and dimensions). The bifaciality factor of 65% ± 5% shows that the back can produce, in good reflected light conditions, up to about two thirds of what the front produces - the real gain depends on how light in colour the surface underneath is and on how much free space is left under the modules. The glass-glass structure withstands 5400 Pa of pressure on the front and 2400 Pa on the back, and the standard cable of 350 mm is designed for end to end installation, in long rows.

At STC: 650 W, Voc 54,00 V, Vmp 45,30 V, Isc 15,06 A, 144 N-type ABC cells (6 x 24), front efficiency 24,1%. Laminate with tempered glass 2,0 + 2,0 mm, anodised aluminium frame of 30 mm, MC4 EVO2 / MC4 EVOA connectors. Coefficients -0,26 %/°C for Pmax, -0,22 %/°C for Voc and +0,05 %/°C for Isc; maximum system voltage 1500 V DC. It suits photovoltaic plants, industrial halls and ground structures with high albedo.

Who it suits

Suitable for ground-mounted plants, carports and agrivoltaic structures from 250 kWp upwards, where free space remains under the modules and the ground reflects light well.

Terms explained

• Bifaciality factor: How much the back of the panel produces compared with its front; 65% means that, in good reflected light, the back can add up to about two thirds of the front's production.
• Albedo: How much the surface under the panels reflects light; light gravel, mown grass or snow reflect a lot, black asphalt almost not at all.
• Tempered glass: Heat-treated glass, much more resistant to impacts and to temperature variations than ordinary glass.

Technical specifications

Recommended applications

• Ground-mounted photovoltaic plants with high albedo (gravel, short grass, snow)
• Industrial projects from 250 kWp to several MWp
• Carports and agrivoltaic structures where the rear face is exploited
• 1500 V systems with high power string inverters

Warranty

15 year product warranty / 30 year linear performance warranty

Technical details

Series-level specifications — valid for the product family

AIKO-G650-MCH72Dw is the 650 W bifacial module of the AIKO platform with 144 N-type ABC cells (6 x 24), sold under the names Polaris 1N+ / Stellar 1N+72 Dual-Glass (the 635-660 W range). It has an overall size of 2382 x 1134 x 30 mm and a front efficiency of 24,1%, one of the highest in the large format module category.

At STC the parameters are Voc 54,00 V, Vmp 45,30 V and Isc 15,06 A. The cells are laminated between two sheets of 2,0 mm tempered glass, with a 30 mm anodised aluminium frame; the bifaciality factor declared for the platform is 65 +/-5%, so the rear face adds energy in proportion to the albedo of the surface under the module. The temperature coefficients are -0,26 %/degree C for power, -0,22 %/degree C for Voc and +0,05 %/degree C for Isc.

The glass-glass structure without a front grid reduces the risk of microcracks and hot-spots and provides a mechanical strength of 5400 Pa on the front and 2400 Pa on the back. The maximum system voltage is 1500 V DC, the connectors are MC4 EVO2 / EVOA, and the standard cable is 350 mm - a length designed for end to end installation in ground rows. The module weighs about 32-33 kg and suits photovoltaic plants, industrial halls and ground structures with high albedo.
