China-headquartered All Back Contact (ABC) solar module and integrated solar-storage-solutions manufacturer AIKO has signed 1 GW of Gen 4 agreements at All Energy Australia where the new module range was also debuted ahead of its local market release.
The Gen 4 range includes the Gen 4 ABC 4.0 INFINITE Ultra cell, featuring six process upgrades that lift average production cell efficiency from 27.2% to 27.4%.
At the panel level, zero-gap cells, hidden rear connections (InvisiRibbon) and tighter string spacing cut non-generating area by about 20%, so 97% of the surface now produces power.
Every ABC INFINITE Ultra series format gains up to 20 W over the previous generation, at exactly the same size and weight, which means up to 30 W more power per panel, compared to TOPCon panels of the same dimension, the company said.
The 60-cell panel (1,954 × 1,134 mm) reaches 560 W, and the 72-cell panel (2,382 × 1,134 mm) reaches 700 W at 25.9% efficiency, the highest in the range.
Rear-side generation weakness is addressed by Gen 4 with the 66-cell bifacial panel now reaching up to 85% bifaciality and 670 W, which opens back contact to high-albedo sites, carports, ground-mounted systems and solar farms.
Agreements and growth
The company said the agreements show strong demand for its ABC solar modules from installers and customers, and which have already seen 1 GW of its panels delivered to Australian rooftop and grid-scale projects.
AIKO ANZ Head Thomas Bywater said the company is proud to have delivered its first GW of ABC solar to Australian homes and to have become the panel of choice in under three years.
“As Australia moves to unlock its ‘missing middle’ through the expanded rebate for systems up to 1 MW, AIKO is working closely with its distribution partners to bring high-efficiency solar solutions to commercial rooftops, helping Australian businesses access the full value of solar,” Bywater said.
AIKO said to respond to the company’s market growth it is expanding a local team and will focus on commercial and industrial (C&I) and utility-scale solar, with a growing presence in New Zealand.
AIKO Head of APAC Alex Hang reflected on AIKO’s arrival into the Australian market, when ACB solar technology was new to most installers.
“Today, it is the panel so many of them choose for their own roofs,” Hang said.
“That journey belongs to the partners, installers and customers across Australia and New Zealand who put their trust in AIKO early. With Gen 4 and a growing local team, we are ready to deliver and ready to scale.”
Solar carport solution
At All-Energy Australia 2026, the company displayed a solar carport solution in partnership with local partner Canyon Solar, a Mittagong, New South Wales (NSW), business that designs prefabricated, modular solar canopies.
Built with AIKO panels, the carport gives facilities whose roof space is limited for the system they need, a way to generate more clean energy from the space they already have.
AIKO said it has become the No. 1 panel brand in OpenSolar quoting, with close to 20% of active monthly solar proposals nationwide.
Installers also voted AIKO No. 1 in the SolarQuotes Installers’ Choice Awards in both 2025 and 2026 and ranked it the best panel in SolarCalculator’s 2026 Solar Installer Survey, with an average score of 9.4 out of 10.
Gen 4 panels will be available in Australia following Clean Energy Council listing.
