Seldom does a solar module maker enter the Australian market without resistance. Established industry leaders healthily occupy a limited market share for distribution access, vendor sentiment and consumer appeal. Therefore, something must stand out within a product to improve stakeholder value and disruptive traction. Aiko, indeed, has a specification wow factor. Now embedded on many Australian rooftops after their first year in the local market, we gain an understanding of the real-world performance of Aiko solar panels and their acclaimed specifications.

Australia is an interesting proposition for module manufacturers. It is one of the most competitive markets globally, as some of the world’s largest volume manufacturers wrestle for improved market share through fractions of innovative differences. With such a competitive space to enter, Aiko’s proposition to the market needs to be solid, and it is.
In June 2023, Aiko Solar panels were in the spotlight of many product analysts internationally after acquiring one of the world’s most coveted international awards, the InterSolar Award for Innovation. Leveraging this innovative spotlight, in 2025, Aiko continues to push the module efficiency limits on the world stage with the most significant efficiency leaps in recent history.
The ideal Aiko solar panels for residential rooftops in Australia are the 440W Neostar 2S (all-black) and the Aiko 475W Neostar 2P series. Each is the perfect multiplier towards STC (subsidy) eligibility for a solar energy system without batteries. If you’re not concerned with maximum solar array size without batteries, the ideal multiplier for a bespoke system is the highest efficiency in a black danel design, the 450W Neostar.
Residential suitability: (order) Most ideal to least.
1. Aiko Neostar 2S (440-450 W): Certain system designs prefer multipliers of 450W. Therefore, the Aiko Neostar 2S 450W module provides an all-black solution. The most popular all-black Aiko solar panel in Australia possesses a comparative market efficiency, yet where it excels compared to alternative black solar panel designs is with an elite temperature coefficient of -0.26%/°C. That’s peak generation in temperatures above 25°C, a common scenario in Australia.
2. Aiko Neostar 2P (475 W): Solar panels in a 475W power class are nothing new in 2025. However, Aiko is the only panel capable of providing such a power class in a more accommodating residential frame size, thanks to a mind-blowing 23.8% module efficiency. Combine this with Aiko’s unique partial shade optimisation inbuilt, and the Neostar 2P is unquestionably Australia’s current most powerful solar panel per m2.
3. Aiko Comet series: The ideal Aiko series for large-scale commercial and industrial scenarios. Discovery improved module efficiency through a more internally controlled environment with increased dimensions of industry-grade solar modules in 2025. 24.1% (24.8% international) maximum module efficiency is industry-leading, coupled with a -0.26%°C high-yielding performance is assured in Australian conditions.
4. Aiko Stellar series: The Aiko Stella series provides Aiko performance in a utility-scale format. Its larger footprint for better LCOE improves module efficiency by up to 24.4% [25.15% announced]. Now boasting up to 25% module efficiency, Aiko is the leader. But it doesn’t end there. The Aiko efficiency roadmap is 40% by 2030. Certain brands shape industries: Intel, Apple, Google, Tesla, and now Aiko in silicon photovoltaic module innovation.

Each Aiko Solar panel undoubtedly has a best-case scenario yet can maximise most rooftop surface areas in power output and high-yielding performance (kWh). All maintain above-average performance as temperatures increase above 25°C. For residential solar installations in 2025, Perth Solar Warehouse recommends the better-suited Aiko solar panels for most turnkey energy system solutions are the 440W Neostar 2S or the 475W Neostar 2P, with their ABC n-type solar module technology as the perfect maximum system size multiplier.
Suppose you’re limited on rooftop surface area and looking to maximise the power output; Aiko’s Neostar 2P is unmatched with 23.8% efficiency. However, the Aiko Neostar 2S range is the highest-performing all-black solar panel when streamlining aesthetic design. Another ideal STC (subsidy) multiplying solar panel is the new 510W Aiko Neostar 2S, recently released in Australia. Keep in mind that this Aiko solar panel has increased dimensions over the 440W Neostar 2S with the same technology inside. A larger footprint solar panel, it’s best suited for commercial installations seeking improved all-black aesthetics.
