en.Wedoany.com Reported - LONGi launched the Hi-MO 9 series of scenario-based PV product portfolios at the Intersolar Europe exhibition in Munich, Germany, on June 24, 2026. Centered on the high-efficiency Back Contact (BC) technology platform, the series includes four specialized variants: Ice-shield, Sea-shield, Edge, and Hydro Clear, designed to address different application scenarios such as hail, offshore corrosion, wind and snow, and dusty environments.
With the accelerated deployment of global solar projects, developers face challenges such as extreme weather and land constraints. Instead of adopting a standard module approach, LONGi's new product portfolio enhances structural and material properties to ensure long-term asset safety, maximize power generation, and reduce operational and maintenance (O&M) expenses across different deployment environments.
The Hi-MO 9 Ice-shield module is developed for regions prone to severe hail and extreme winds. Standard IEC testing relies on 25mm hail impact, but historical data shows that over 30% of hail events involve larger sizes. This module uses LONGi's TaiRay silicon wafers with 16% higher strength, paired with a thickened 3.2mm front glass capable of withstanding 55mm hail impact, resulting in a 4.5-fold improvement in overall impact resistance and a 70% reduction in glass breakage probability. Its high-strength aluminum alloy frame achieves a yield strength of 270 MPa, combined with highly reliable BC cell "single-line" welding and OBB structure, reducing cell edge stress by 48% compared to TOPCon products. The module supports loads of ±5400Pa on fixed structures and ±3600Pa on mainstream tracking systems. This product has shipped over 1GW globally.
The Hi-MO 9 Sea-shield module is specifically designed for offshore PV environments. It features a molecular-level passivated frame and weather-resistant anodized coating, passing Grade 8 salt spray testing and suitable for C5 and CX corrosive environments. Its quadruple protection system includes a corrosion-resistant frame, sealed junction box, and connectors, using a dual-POE encapsulation formulation with low water vapor transmission rate, offering anti-PID and anti-aging performance. The glass structure is denser, with excellent full-seal surface durability. To resist wave forces and high wind loads, the module adopts a high-load design combining bolts and clamps, withstanding a maximum wind speed of 65.1 m/s (Category 16-17 typhoon) on the front side.
The Hi-MO 9 Edge product (not exhibited at the show) targets environments affected by high winds, low temperatures, and sandstorms, using a patented high-strength steel frame to replace traditional aluminum, increasing material strength by 150% and wind load capacity by 25%, with a basic load guarantee of 6000/3000Pa. By removing the C-side frame obstruction, the rear light-receiving area increases by 2.5%, and the bifaciality rate improves by 2%. The A-side frame profile is over 20% lower than standard modules, facilitating dust and snow shedding. The steel-based frame reduces product carbon emissions by approximately 70% compared to typical aluminum frames, helping meet requirements such as the EU Carbon Border Adjustment Mechanism (CBAM). Its plug-in, grounding-free design, simulated for a 100MW ground-mounted PV power plant, can reduce 152,000 grounding wires and 1,689 hours of installation time.
The Hi-MO 9 HydroClear module is developed for dusty environments and snow zones. The short-side frame is flush with the front glass, reducing dust accumulation at the bottom and facilitating snow shedding. The module uses LONGi's HPBC 2.0 technology, offering excellent low-irradiance performance and tolerance to uneven light, with a verified average monthly power generation gain of over 2%. Dust and snow easily slide off under natural wind and gravity, preventing mud strip formation and uneven load risks from stagnant melting snow, reducing O&M costs.
EUPD Research awarded LONGi's scenario-based products the 2026 European Top Innovation Award, won in the highly competitive "Modules" category. Customers in high-dust areas can opt for a dust-free glass upgrade, whose surface micro-rough peaks weaken dust adhesion, allowing natural dust shedding. All four products are commercially ready and entering mass production. LONGi is showcasing at booth A2.170 at Intersolar Europe 2026.
