AIKO STELLAR 1N+72 635W–660W Bifacial Solar Panel
The AIKO STELLAR 1N+72 solar panel is a high-power bifacial photovoltaic module designed for utility-scale solar farms and other large PV installations. The series combines N-Type ABC cell technology with a dual-glass structure and offers six power ratings from 635W to 660W.
With module efficiency reaching 24.4%, the STELLAR 1N+72 series helps increase installed capacity within a limited project area. Its bifacial design can also generate additional energy from light reaching the rear side of the module, subject to ground reflectivity, mounting height, row spacing and site conditions.
Key Features
- 635W–660W power range: Six models are available for different PV system requirements.
- N-Type ABC cells: All Back Contact cell technology removes front-side busbars and increases the active light-receiving area.
- Up to 24.4% efficiency: High module efficiency supports greater installed capacity per unit of land.
- Bifacial power generation: A 75±5% bifacial factor enables rear-side energy generation under suitable installation conditions.
- Dual-glass construction: The module uses 2.0+2.0 mm coated semi-tempered glass.
- Better temperature performance: The Pmax temperature coefficient is −0.26%/°C.
- 1500V DC system compatibility: Suitable for the electrical design of large-scale PV systems.
- Long-term warranty: 15-year product warranty and 30-year linear performance warranty.
N-Type ABC Cell Technology
ABC means All Back Contact. The electrical contacts are positioned on the rear side of the solar cells, leaving the front surface free from conventional metal grid lines. This design increases the effective light-receiving area and gives the module a clean, uniform appearance.
The STELLAR 1N+72 module contains 144 N-Type ABC cells in a 6 × 24 configuration. Its electrical design provides a positive power tolerance of 0 to +3%, helping ensure that the delivered module power is not below the rated output under standard test conditions.
Bifacial Dual-Glass Design
The module uses a bifacial dual-glass structure with a specified bifacial factor of 75±5%. In a properly designed installation, reflected sunlight can reach the rear side of the module and contribute additional power generation.
Actual bifacial gain is not a fixed percentage. It depends on ground albedo, module height, tilt angle, row spacing, shading and other site-specific factors. A project simulation should therefore be completed before estimating total system energy yield.
