Dual-Glass Module | 655W-675W
The AIKO STELLAR 3N+72 Dual-Glass 655W-675W stands out as a high-output, high-efficiency solar module for Australian projects where roof or installation conditions can accommodate its large format. Its N-type ABC cells, dual-glass construction, 25.0% maximum efficiency, low published degradation and 15-year product/30-year performance warranties make it a strong premium contender. For homeowners and businesses comparing AIKO solar panels in Australia, the best approach is to compare the STELLAR 3N+72 against other suitable panels on whole-system value, usable roof area, expected energy yield, installer capability, warranty terms and total installed cost. |

Key features of the AIKO STELLAR 3N+72 Dual-Glass
The AIKO STELLAR 3N+72 Dual-Glass series incorporates advanced manufacturing innovations designed to maximise clean energy output while lowering balance-of-system (BOS) costs. Below are the key core features that define this high-output panel series:
- N-Type All-Back Contact (ABC) Architecture: Routing all electrical connections to the rear of the solar cell keeps the front face completely unshaded by metal busbars. This design maximises sunlight absorption and enhances overall module efficiency up to 25.0%.
- Dual-glass structural design: Built with 2.0mm front and 2.0mm rear semi-tempered glass, this construction offers superior mechanical strength and moisture protection. It eliminates backsheet degradation and significantly reduces the risk of micro-cracking over time.
- Cell-level partial shading optimisation: Integrated cell-level management ensures localised shading from soot, trees, or structural obstacles affects only the affected cell, rather than reducing the yield of the entire string. This provides a distinct advantage on complex Australian commercial roofs.
- Low temperature coefficient: With an ultra-low temperature coefficient of -0.26%/°C for maximum power (Pmax), this module retains higher power output during intense heatwaves. It minimises heat-induced power loss across hot Australian regions.

AIKO STELLAR 3N+72 Dual-Glass Warranty
- Product warranty: Backed by a robust product materials and workmanship warranty (typically 15 to 25 years depending on local distributor registration).
- 30-year performance warranty: Guarantees at least 99.0% power output after year one and a maximum annual degradation of 0.35% from year 2 through year 30.
Pros of the AIKO STELLAR 3N+72 Dual-Glass
- High power output per panel: With outputs up to 675W in the Australian range, the STELLAR 3N+72 delivers substantial nameplate capacity per module. This can help large residential, commercial, and industrial arrays where reducing module count matters in practice.
- Excellent module efficiency: The 675W version reaches 25.0% efficiency, while even the 655W version is rated at 24.2%. Higher efficiency can be especially valuable when roof area is constrained.
- N-type ABC technology: The N-type ABC architecture gives the panel a modern cell platform designed around high efficiency and low degradation. AIKO positions the STELLAR 3N+72 as part of its third-generation product family.
- Dual-glass construction: A glass-glass module avoids the conventional polymer backsheet and offers robust construction for demanding installations. The current ANZ datasheet specifies 2.0mm + 2.0mm coated semi-tempered glass.
- Strong published degradation profile: A maximum 1% first-year degradation followed by no more than 0.35% annually from years two to 30 supports the panel’s long-term value proposition.
- Long warranty coverage: A 15-year product warranty and 30-year performance warranty provide long-term coverage that aligns with the expected service life of a quality solar installation.
Cons of the AIKO STELLAR 3N+72 Dual-Glass
- Large physical footprint: At 2,382mm long and 1,134mm wide, the module is considerably larger than many conventional residential solar panels. Roof obstructions, setbacks, access pathways and mounting layouts therefore need careful assessment.
- Relatively heavy module: At approximately 32.2kg, handling the panel can be more demanding than handling smaller modules. The installer must confirm that the roof structure, mounting equipment, and installation method suit the specific site.
- High-power electrical characteristics require system compatibility
The panel’s current and voltage characteristics must match the inverter, string configuration, maximum input current, and applicable design requirements. Never select a high-wattage panel based on wattage alone. - Bifacial gains are site-dependent
Although the dual-glass design supports bifacial operation, the extra rear-side generation potential depends on the installation environment. A conventional rooftop with little rear irradiance may deliver far less additional energy than an elevated, reflective or purpose-designed bifacial installation.
Applications for the AIKO STELLAR 3N+72 Dual-Glass
The AIKO STELLAR 3N+72 Dual-Glass is particularly suited to projects where high module output and efficiency can justify its larger physical format. AIKO positions the Australian product in its utility-oriented STELLAR range, but the module also suits larger commercial installations and carefully designed residential projects.
Residential solar: Large homes with generous roof areas may benefit from 655W-675W modules because fewer panels can provide substantial nominal system capacity. However, installers should verify whether the dimensions work around skylights, roof edges, chimneys, hips, valleys and other constraints.
For smaller homes, the panel’s physical size may outweigh its high wattage. In those situations, a smaller high-efficiency panel can sometimes create a more practical roof layout, even if it requires more modules.
Commercial and industrial solar
Commercial rooftops often fit high-output modules more naturally. Warehouses, factories, agricultural buildings, and other large roofs may have enough uninterrupted space to accommodate the STELLAR 3N+72’s dimensions while using fewer modules for a given system capacity.
The potential bifacial contribution may also be more meaningful on appropriate commercial structures. Nevertheless, model the expected rear-side gain rather than assume it.
Utility-scale applications
The module’s 1,500V maximum system-voltage rating and high power output align with the high-capacity system architecture commonly considered for larger projects, subject to the full system design and applicable standards.
For utility projects, however, module-level specifications are only part of the equation. Developers should also evaluate energy yield, BOS costs, transport, mounting configuration, inverter compatibility, procurement terms and warranty arrangements.
Solar-plus-battery systems
The STELLAR 3N+72 can form the generation side of a solar-plus-battery system. Adding a battery lets you store more daytime solar production and use it later rather than exporting it to the grid.

Is the AIKO STELLAR 3N+72 Dual-Glass right for you?
The AIKO STELLAR 3N+72 Dual-Glass 655W-675W is a compelling option if you prioritise high module output, strong efficiency, modern N-type ABC technology, and long-term performance. The 675W model reaches 25.0% efficiency, while the range carries a 15-year product warranty and a 30-year performance warranty.
It makes the most sense when the site can physically accommodate a large 2,382 × 1,134mm module and the electrical design matches the panel. The right decision should therefore be based on the complete solar system—not simply on the biggest wattage number.
The AIKO STELLAR 3N+72 is worth considering if:
- You want high-output solar panels with up to 675W per module.
- Your roof or project has sufficient space for large-format modules.
- You value high panel efficiency, with up to 25.0% in the Australian 675W model.
- You want an N-type ABC solar panel with a low published degradation rate.
- You prefer a dual-glass construction.
- You are considering a larger residential, commercial or industrial solar project.
- Your installer can properly evaluate the panel’s electrical characteristics and mounting requirements.
- Your site could benefit from bifacial generation.
You may want to consider another panel if:
- Your roof has numerous obstacles or limited usable space.
- Manual handling and installation weight are major constraints.
- You want the lowest upfront module price rather than premium specifications.
- Your system design doesn’t materially benefit from the module’s high output or bifacial characteristics.
- A smaller panel would improve the overall roof layout.
Before signing a quote, ask your installer to identify the exact AIKO model number, wattage, inverter pairing, string configuration, mounting method and applicable warranty documentation. You should also confirm product availability and eligibility for any relevant Australian programs or incentives at the time of installation.
