Dual-Glass Module | 655W-675W
If you are comparing high-output solar panels for a large Australian home, commercial property, or utility-scale installation, the AIKO STELLAR 2N+78 Dual-Glass 765W-785W deserves a close look. This second-generation STELLAR module combines N-type ABC cell technology, dual-glass construction, high module efficiency and a relatively strong temperature coefficient in a format designed primarily for larger solar installations.
For Australian buyers, the appeal is straightforward: a 785W panel delivers substantial nameplate capacity with fewer modules.

Key features of the AIKO STELLAR 2N+78 Dual-Glass
- Up to 785W output: The Australian-listed range runs from 765W to 785W, delivering substantial capacity per module.
- Up to 24.4% efficiency: The 785W model reaches 24.4% module efficiency under standard test conditions.
- N-type ABC cells: AIKO uses its N-type All Back Contact architecture for the module platform.
- Dual-glass construction: A 2.0mm + 2.0mm coated semi-tempered glass configuration provides a glass-on-glass design.
- Temperature coefficient of -0.26%/°C: This helps limit power losses as module temperature rises.
- Bifacial capability: The Australian datasheet specifies a 70±5% bifacial factor, although actual rear-side energy contribution depends heavily on installation conditions.
- Micro-crack resistance: AIKO identifies micro-crack resistance as one of the STELLAR platform’s technical features.
- 1500V system compatibility: The module is specified for systems with a maximum DC system voltage of 1500V.

AIKO STELLAR 2N+78 Dual-Glass Warranty
The AIKO STELLAR 2N+78 Dual-Glass warranty is one of the product’s stronger selling points. AIKO’s Australian product page specifies a 15-year product warranty and a 30-year performance warranty.
AIKO’s published warranty documentation states a first-year power degradation limit of 1%, followed by a maximum annual degradation rate of 0.35% from years two through 30. The published performance guarantee reaches 90.6% at year 25 and 88.85% at year 30, with the performance warranty applying to the module’s front-side rated power.
Pros of the AIKO STELLAR 2N+78 Dual-Glass
- Very high power output: Up to 785W per module can significantly reduce the number of modules needed for large installations.
- High efficiency: The 785W model reaches up to 24.4% efficiency, helping maximise generation from available installation area.
- Strong temperature performance: The -0.26%/°C Pmax temperature coefficient suits projects where modules regularly operate at high temperatures.
- N-type ABC technology: AIKO’s N-type ABC architecture is designed around high-efficiency cell performance and contributes to the module’s high power density.
- Long warranty period: A 15-year product warranty and 30-year performance warranty provide long-term protection for qualifying installations.
- Durable dual-glass design: The 2.0mm + 2.0mm dual-glass construction, Class A fire rating, and specified mechanical-load ratings make the module suitable for demanding, large-scale environments.
Cons of the AIKO STELLAR 2N+78 Dual-Glass
- Very large physical footprint: At 2.465m × 1.303m, the panel is substantially larger than many residential modules, making rooftop handling and layout more challenging.
- High module weight: At approximately 39.8kg ±3%, the panel requires suitable handling procedures and a mounting system designed for its dimensions and weight.
- Not ideal for every residential roof: A smaller, lower-wattage module may be a more practical solution when roof sections are fragmented, access is restricted, or installers must work around numerous obstacles.
- Requires careful inverter and system design: The relatively high operating current means you need to check the inverter MPPT and maximum-current specifications carefully during system design.
Applications for the AIKO STELLAR 2N+78 Dual-Glass
The AIKO STELLAR 2N+78 Dual-Glass 765W-785W is most compelling where high module power reduces balance-of-system complexity and improves installation density. AIKO categorises the STELLAR family for utility scenarios, reinforcing its suitability for larger projects.
Suitable applications include:
- Utility-scale solar farms where fewer modules can simplify large arrays.
- Commercial and industrial rooftops with sufficient roof area, structural capacity and access.
- Large warehouses and logistics facilities that require high-capacity solar generation.
- Agricultural and rural solar projects where available land or large structures can accommodate the module dimensions.
- Ground-mounted solar systems where panel size and handling can be managed efficiently.
- Large energy projects paired with battery storage, subject to appropriate inverter and system engineering.
For smaller homes, the answer is more nuanced. If the roof has large uninterrupted sections and the installer is comfortable with large-format modules, the STELLAR 2N+78 can work; otherwise, a smaller module may make the installation easier without materially compromising the homeowner’s overall system design.
Is the AIKO STELLAR 2N+78 Dual-Glass right for you?
Whether the AIKO STELLAR 2N+78 Dual-Glass is right for you depends less on its impressive 785W headline number and more on the project around it. High wattage matters most when the site’s roof, land area, mounting arrangement, and electrical equipment can support it.
It may be a strong choice if:
- You are developing a commercial, industrial or utility-scale solar project.
- You have large, relatively unobstructed installation areas.
- You want to reduce the number of modules required for a high-capacity system.
- High efficiency and temperature performance are important.
- You are comfortable using a large-format module.
- Your inverter and electrical design can accommodate the module’s current characteristics.
You may want to consider alternatives if:
- You have a small or complicated residential roof.
- Roof access is difficult.
- The installation has strict module-size or weight limitations.
- Your preferred inverter has limited MPPT current capacity.
- Your project would benefit more from flexible module placement than maximum watts per panel.
