Chinese solar module manufacturer Risen Energy has unveiled a new heterojunction (HJT) solar module featuring a dual-layer optical design to reduce glare.
The company said the new product is part of its Hyper-ion series and is designed for installations with stringent glare-control requirements, such as those near airports and residential areas, where reflected sunlight may cause visual disturbances.
“Risen Energy’s capabilities in photovoltaic optical safety extend beyond product development. It is also the principal drafting organization behind T/CPIA0119-2025, the group standard for Photovoltaic Module Glare Testing Method,” the manufacturer said in a statement. “The launch of Hyper-ion anti-glare module represents the translation of this accumulated technical and standardization expertise into a commercial product.”
According to Risen Energy, the module uses a dual-layer optical design combining a micron-scale matte glass surface, produced through a process it calls “nanocrystalline phase reconstruction,” with technology to suppress internal reflections. The company did not provide further technical details about the process.
The manufacturer said tests conducted by Germany’s TÜV Rheinland showed 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, compared with a limit of 20,000 cd/m². The module also achieved a specular reflectance as low as 0.85%, according to the company.
The RSM132-8-710-730BHDG module comes in five versions, with power outputs of 710 W, 715 W, 720 W, 725 W and 730 W. Their conversion efficiencies range from 22.9% to 23.5%, while open-circuit voltages range from 50.01 V to 50.33 V and short-circuit currents from 18.00 A to 18.38 A.
The bifacial module features 132 HJT cells and measures 2,384 mm × 1,303 mm × 33 mm. It weighs 37.5 kg and features 2 mm anti-glare glass on the front and 2 mm heat-strengthened glass on the rear, along with an anodized aluminum alloy frame.
Under bifacial nameplate irradiance conditions, with rear-side irradiance of 135 W/m², the module delivers between 796 W and 818 W, according to the manufacturer’s specifications. With a 10% rear-side power gain, its equivalent power output ranges from 781 W to 803 W.
The panel has a temperature coefficient of -0.24%/C for maximum power, an operating temperature range of -40 C to 70 C, and a maximum system voltage of 1,500 V. It can withstand mechanical test loads of up to 5,400 Pa on the front and 2,400 Pa on the rear, depending on the installation method.
Risen Energy offers a 15-year product warranty and a 30-year linear power output warranty. The company specifies an annual degradation rate of 0.3% over 30 years, with guaranteed power output of 90.3% at the end of the warranty period.
