Hi-MO X10 Guardian Light Design

LONGi’s Hi-MO X10 Guardian Light Design uses HPBC 2.0 back-contact cells to deliver up to 560W at 24.8% efficiency. It weighs 16.3kg, around 30% less than conventional modules, according to LONGi. The lighter format targets commercial rooftops where structural load limits restrict panel selection. wf-eu.longi.com

For older sheds and other weight-sensitive buildings, lower panel weight may reduce reinforcement requirements. Roof condition, mounting and wind loads still need assessment. It is an option to consider where weight matters, rather than a way to avoid structural checks.

Other Panel Models:

• Hi-MO 5 Series: Monofacial, bifacial, and Ice-Shield versions, built for durability and extreme weather conditions.

Aiko

• Panel Models:
  • NEOSTAR 3N+78 Dual-Glass: 675W-700W, 22.9% efficiency, ultra-high power for large installations.
  • COMET 2U72 Mono-Glass: 640W-670W, high-power PERC technology.
  • STELLAR Polaris 1N+72 Dual-Glass: 635W-660W, bifacial, TOPCon N-type.

AIKO Neostar 3 Series | Neostar 3P54 and 3S54 models | premium AIKO Z Series

Industry-Leading Efficiency (24.5% – 25.0%) The Neostar 3P54 is notable for being one of the first residential-sized modules (under 2m²) to achieve a massive 500W output at 25.0% efficiency in mass production. AIKO hits these numbers using their signature N-Type ABC (All Back Contact) architecture, which moves all busbars and electrical contacts to the rear of the cell so the front face can absorb 100% of incoming sunlight

Solar panel technologies keep progressing and becoming more impressive. The 2025 exhibition in China showed most solar panel manufacturers reaching 24.5% to 25% module efficiency. Aiko, one of the leaders, also showed strong results. Panels are becoming more shade-resistant, with companies demonstrating how effective their panels are under partial shade. High efficiency and shade resistance are especially important for off-grid systems, where many are located in the bush and every watt counts. Some companies also showcased clear window solar panels and very flexible solutions for curved surfaces.

Advanced Partial Shading Optimisation: The shade-resistance technology you mentioned aligns perfectly with AIKO’s proprietary cell-level partial shading optimisation. Traditional panels use bypass diodes that shut down an entire third of a panel if even a single cell is obstructed (like by a stray leaf or tree branch). AIKO’s ABC technology allows current to bypass individual shaded cells without knocking out the rest of the string. This keeps the panel producing power under patchy shade—a massive advantage for off-grid bush setups where trees are a constant factor.

Next-Gen Concept: The clear window and flexible solar panels align with AIKO’s latest generation announcements, such as their INFINITE ULTRA utility line and new architectural concepts designed to push the physical boundaries of back-contact (BC) technology

‘Air Series’ 450W Ultra-Lightweight Solar Panel

In a move to lighten the load for solar installations, Aiko, a solar manufacturer from China, has rolled out a new module in the Australian market that tips the scales at a mere 8.8kg. Dubbed the ‘Air Series,’ this 450W marvel swaps traditional solar glass for a high chemical plastic, shedding weight without compromising too much on power. While the switch does result in a slight dip in output—about 10V less than its glassy counterpart—the module still packs a punch with a peak power output of 450W.

Measuring 1758mm by 1137mm and framed with a 25mm border, the module stands out in the lightweight category. Unlike competitors such as Sunman, whose lightweight modules for roofs with low load-bearing capacities go frameless, Aiko’s inclusion of a frame bolsters reliability. The frame’s presence helps mitigate weathering risks associated with an exposed junction box.

However, it’s worth noting that while the module shines in performance, its product warranty is a modest 12 years, though it aligns with industry standards at 25 years for performance warranty.

Sunman

eArc flexible solar panels

Sunman’s eArc flexible solar panels offer the same durability as traditional glass modules, making them a revolutionary choice in the solar energy market. They have successfully passed rigorous durability and safety tests, including IEC 61215:2016, IEC 61730:2016, and UL1703 (USA), confirming their resilience to prolonged exposure to open-air climates. Furthermore, eArc has undergone additional quality assessments, including 3000 hours of damp heat, UV exposure equivalent to 25 years, potential-induced degradation (PID), salt mist, and ammonia corrosion tests.

As the modern economy increasingly embraces electric and zero-emission transportation modes like trains, yachts, mopeds, and logistic vehicles, eArc can play a crucial role in electrifying the transportation sector. It enhances cruising distances and powers essential functions such as lighting, air conditioning, and tail lifts.

For low load-bearing roofs, eArc presents an ideal solution. Approximately 40% of commercial and industrial roofs do not meet the minimum load capacity required for conventional glass modules. Glass modules typically need a minimum load capacity of 15 kg/m² for installation. In cases where buildings fall below this threshold, costly and disruptive structural reinforcements are necessary to accommodate solar installations. eArc eliminates this need, providing a lightweight and efficient alternative for solar energy generation.
