LONGi Solar has announced that its high-efficiency photovoltaic modules, led by the flagship Hi-MO series including Hi-MO X10, have achieved a Class A fire resistance rating following testing by the Emirates Safety Laboratory (ESL), alongside certifications from TÜV.
The company said the milestone underscores its focus on delivering safe and high-performance solar solutions tailored to the Middle East, where extreme climate conditions and strict regulatory requirements demand robust product reliability.
The Class A rating represents the highest fire safety classification available, indicating maximum resistance to flame spread and external fire exposure. According to LONGi, this makes the modules suitable for a range of applications, including building-applied photovoltaics, rooftop installations, commercial and industrial projects, and high-risk urban environments.
Testing was carried out in line with international standards, including IEC 61730-2:2023 for fire hazard testing, the ASTM E108 fire test, and the UAE Fire and Life Safety Code of Practice (2018). The modules passed a series of assessments covering fire spread, ignitability, bypass diode thermal performance, and reverse current overload.
The Middle East, particularly the UAE, enforces some of the world’s most stringent fire safety regulations for solar installations. By securing ESL and TÜV Class A certifications, LONGi said its modules meet regional compliance requirements, assuring developers, EPC contractors and project owners.
The company added that the modules are designed to withstand extreme heat and environmental stress, supporting long-term deployment across GCC markets.
LONGi’s Hi-MO modules incorporate a range of engineering features aimed at enhancing fire resistance and durability. These include a dual-glass bifacial structure using heat-strengthened glass, POE-EVA encapsulation technology, IP68-rated junction boxes and anodised aluminium frames.
The company said this design helps maintain structural integrity under extreme fire conditions, with no flaming debris or structural failure observed during testing.
As countries across the Middle East accelerate their transition towards renewable energy, safety remains a key consideration. LONGi said its Class A-certified modules will support secure and scalable solar adoption across residential, commercial and utility-scale projects.
“Achieving the Class A fire rating reflects our ‘Safety First’ philosophy. Our modules are engineered to meet the unique environmental and regulatory challenges of the Middle East, ensuring long-term reliability and peace of mind for our partners.”
