LONGi introduces a Class A fire-resistant module to suppress ignition and limit fire spreading on commercial rooftops

Photovoltaic fire safety on commercial buildings gains significant attention across Europe. European and international fire standards demand strict compliance to prevent rooftop disasters. LONGi addresses this market challenge with the Hi-MO X10 Guardian Fire-Resistant module. The company presents this specialized photovoltaic product to the European market to safeguard critical infrastructure. The hardware functions as a specialized BC module to prevent industrial accidents in environments with stringent safety requirements. Facility managers deploy these panels across multiple high-risk scenarios to create a reliable roof safety perimeter. Target locations include data centers with high value equipment and automated production lines. Warehouses with valuable storage also require this protection to safeguard concentrated assets against uncontrollable losses. Crowded public facilities like hospitals and malls, alongside chemical or textile plants with flammable gases and dust, utilize this technology.  

Integrated cell and glass engineering eliminates internal ignition risks

Standard fire safety evaluations often overlook internal ignition sources. Industry investigations show that hot spots trigger forty percent of solar plant fires. Direct current arcing causes another forty percent of these incidents. To resolve this vulnerability, the Hi-MO X10 architecture features a dedicated dual protection safety design. Upgraded HPBC 2.0 cell technology actively suppresses internal hazards by keeping hot spot temperatures below 100 degrees Celsius. This baseline operating temperature remains approximately 80 degrees Celsius lower than conventional TOPCon products. An enhanced junction box provides six times higher aging resistance to stop electrical failures at the root. For the second line of defense, fire retardant additives form a carbonized barrier to starve the flame of oxygen. A specialized fire-resistant glass simultaneously doubles the burst resistance of the panel due to a high softening temperature.  

Dual testing frameworks prove comprehensive fire protection capabilities

Independent testing institutions evaluate two distinct aspects of hardware safety. The first category covers the reaction to fire. Experts use the EN 13501-1 standard to measure if a solar panel fuels an existing fire. The second category assesses resistance to external flames. European authorities implement the EN 13501-5 framework to test whether a roof catches fire from outside sources. American regulators apply the UL 790 standard to evaluate this same external fire resistance. The new module successfully addresses these rigorous requirements. Mass production units already hold the official TÜV Rheinland Class A fire certification. The manufacturer achieved this premium rating without using thicker glass. This engineering choice preserves the standard mechanical weight. The technical team also submitted official applications for the EN 13501-1 Fire Class B standard. Simultaneous applications cover the EN 13501-5 external roof fire tests for categories t1 through t5. Researchers currently evaluate the hardware to reach the premium EN 13501-1 Fire Class A2 standard. This comprehensive safety profile directly reduces corporate insurance concerns. Qualified projects secure lower premiums through a strategic partnership between LONGi and PICC.  

Optimized physical dimensions and advanced layouts maximize energy yields

The physical construction utilizes 144 cells arranged in a six by twenty-four orientation. Each panel weighs exactly 32.5 kilograms. Dimensions measure 2382 millimeters in length, 1134 millimeters in width, and 30 millimeters in thickness. This structural format delivers up to 670 watts of power output with a maximum module efficiency of 24.80 percent. Advanced anti shading properties cut shading related power losses by up to 70 percent to maintain high yields on crowded commercial roofs. Buyers receive a 15-year warranty for materials alongside a 30-year warranty for the extra linear power output. Performance metrics record a one percent drop in the first year. The system experiences a minor 0.35 percent annual decline through year thirty.
