*500 Watt* Solar Panels For Your Rooftop From Aiko

Solar cell and module manufacturer Aiko has showcased what it says is the world’s first 500 W panel under 2m² (only just) at the All Energy Australia 2025 event in Melbourne.

What Are The Aiko Infinite Neostar 3P54’s Specifications?

Specifications for the third-generation ABC (All Back Contact¹) Infinite mono-glass series — Neostar 3P54 — are pretty impressive:

The AIKO-A-MCE54Mw range has been approved for installation in Australia by the Clean Energy Council. I haven’t seen pricing as yet for the 500-Watt panel, but Aiko gear is generally towards the budget end of the market.

Aiko’s Not Done Pushing The Power Envelope Yet

We could see even more powerful rooftop panels while maintaining the same footprint in the not-too-distant future from Aiko.

Last year Aiko announced it had teamed up with the Australian Centre for Advanced Photovoltaics, aiming to achieve 30% conversion efficiency for back contact cells. As at August 2025, Aiko was achieving above 27% in mass production.

Aiko In Australia

Ailo is a relative newcomer to Australia, launching here early last year and setting up an office in Melbourne.

The company has attracted a lot of attention locally during that time; but also created some controversy over partial shading optimisation claims. That doesn’t seem to have dampened installers embracing the brand; with Aiko winning the SolarQuotes Installers Choice Awards for the best solar panels in 2025  ahead of REC and JinkoSolar — and by quite a margin; scooping up 27% of the vote compared to REC’s 16%.

As well as installers, the company’s panels have proved popular with Australian homeowners too. Aiko solar panel reviews on SolarQuotes from Australians who’ve had them installed have averaged 5 stars from 278 ratings.

Zhejiang Aiko Solar Technology Co., Ltd. was founded in 2009 in China. Originally focused on cell manufacturing, the firm began producing solar panels in 2023, so it’s a new kid on the block in that aspect as well. It has six major production bases in China, supported by three R&D centers — one in Europe and two in China. The company claims to have shipped more than 170 GW of cells and modules since it was founded, and boasts 10,000+ employees globally.

High Power Solar Panel Choices Proliferating

We’ve seen a bunch of high-powered solar panels suitable for installation on Australian rooftops unveiled this year, among them:

• Trina Vertex S+ 475W
• TW Solar TWMNH 470 W
• Risen Energy RSM96-11 475 W 
• Winaico WST-475BDX54-B2 475 W.

And it was only in February 2025 when Aiko launched the Neostar 2P 480W here. At the time, it was claimed to be the first residential panel in Australia to exceed 24% module efficiency. The new 500 W Gen3 Neostar Infinite 3P54 has blasted past that, and is close to a kilogram lighter.

All of the panels listed above have a footprint of just under 2 m² with the exception of Winaico’s, which is a whisker over. 2 m² is generally considered the cut-off limit for rooftop installations, and even then they are challenging for installers to handle.

With so many brand and module choices available to Australians, it can be confusing to determine what to get. Learn about buying the right solar panels for your home.

All Energy Australia is promoted as the largest gathering of renewable energy professionals in the Southern Hemisphere. It was held yesterday and continues today at the MCEC in Melbourne. Some of the SolarQuotes team are attending the event, and they’ll no doubt have some yarns to tell on their return. Sign up for the SolarQuotes weekly newsletter to stay informed.
