The Japanese Kyocera has introduced new 410 W -Zonne -modules for PV systems on the roof in regions with heavy snowfall. The modules have a patented mounting system and are suitable for areas with up to 2.5 meters of vertical snowfall.
“In recent years there has been an increase in damage accident for solar energy generation facilities in snowy areas, where the main cause is the weight of accumulated snow that puts excessive pressure on the mounting frame and modules,” Kyocera said in a statement. “With our new product, the impact of snow accumulation can be minimized and PV systems can be installed safely, even in snowy areas.”
The manufacturer said that the double glass panels, available in Japan from March 2025, have support brackets on the back that make a snow load capacity of 7,500 PA possible, with a vertical snowfall up to 2.5 meters.
“The support brackets are normally separated from the back of the module and only support the panel after bending due to the load of snow accumulation. In addition to wearing the load, the design also minimizes the impact of the pressure exerted through the bracket on the module, “said Kyocera.
The modules did not undergo specific tests, which showed improved safety, lifetime and dirt resistance compared to conventional panels, the company said. It explained that its unique notch structure on the long side of the aluminum frame possible dust on the surface glass can be washed away by rainwater and melting snow.
These high anti-fouling performance helps to suppress a reduction of electricity generation, lower maintenance costs and lowering the failure percentages. The company added that the modules were also made with a Guesting resistant structure that protects them against flying debris.
