The brand-new anti-glare heterojunction solar module released by Risen Energy achieves a maximum efficiency of 23.5% in power conversion and produces an output Power that can go to 730 watts, indicating an important milestone on the way to the merger of high-efficiency PV with tough requirements in the field of light-safety. The new product, known as RSM132-8-710-730BHDG and belonging to the Hyper-ion series, got the highest level in the glare-control certification given by TÜV Rheinland (the Class AAA anti-glare certification).
Specifications and Performance
The module has a temperature coefficient of −0.24%/°C for maximum power and a maximum system voltage of 1,500 V while being rated for mechanical loads of up to 5,400 Pa from the front. Risen provides a 15-year product warranty along with a 30-year linear power output warranty, assuring performance of 90.3% at the term completion with annual degradation at 0.3%.
Dual-Layer Optical Design
What distinguishes this module from conventional anti-glare approaches is its dual-layer optical architecture. Most existing solutions modify only the front glass, which reduces surface reflection but leaves a residual halo caused by light that passes through the glass and reflects off the cell surface beneath. Risen's design addresses both interfaces. The outer glass receives a micron-scale matte texture through a process the company calls "nanocrystalline phase reconstruction," producing a surface gloss as low as 6.7 GU and a haze of 89%, which scatters incident light into soft diffuse reflection. Independently, the HJT cells receive a dedicated anti-reflection and light-absorbing coating that suppresses secondary reflection at the source. The combined effect reduces the module's glare rating by more than 80% compared with conventional modules, while front glass transmittance remains at 93.2%.
TÜV Rheinland measurements confirm the performance: the module achieves a maximum daylight glare probability (DGP) of 0.30, below the Class AAA threshold of 0.35, and a maximum glare luminance of 3,463.94 cd/m² against a limit of 20,000 cd/m². Specular reflectance is as low as 0.85%.
Standards, Compliance, and Market Context
The launch carries significance beyond product specifications. Risen was the principal drafting organization behind T/CPIA 0119-2025, the group standard for photovoltaic module glare testing, which for the first time established "glare rating" as a quantifiable metric in China's PV testing framework. For airports, highways, and urban public buildings-where glare is treated as a safety or compliance issue rather than an aesthetic preference-a certified, standardized anti-glare rating can function as a de facto market-access requirement.
The timing also reflects the competitive trajectory of HJT. In early 2026, Risen's mass-produced HJT modules reached 23.8% efficiency, reversing a brief period in which TOPCon modules had edged ahead in published efficiency rankings. China's Ministry of Industry and Information Technology has raised the efficiency bar for the top class modules at 23.4% for both TOPCon and HJT. This implies that the efficiency of the Hyper-ion anti-glare module of 23.5% effectively puts it at the threshold for the highest class. Risen's HJT order book reflects the market position of the company too as it has an order of 1.2 GW for HJT module from China Huaneng Group, with around 600 MW already delivered.
For an industry navigating the dual pressures of efficiency competition and increasingly granular siting regulations, the Hyper-ion anti-glare module illustrates a practical pathway: optical safety need not come at the expense of wattage, and standardization can transform a niche technical requirement into a scalable commercial proposition.
