LONGi Solar, a global leader in solar technology, proudly announces that its high-efficiency photovoltaic modules, led by the flagship Hi-MO series, including Hi-MO X10, have successfully achieved the highest results: Class A fire resistance rating following rigorous testing by the Emirates Safety Laboratory (ESL), alongside internationally recognized TÜV certifications.
This milestone reinforces LONGi’s commitment to delivering safe, high-performance solar solutions tailored for the Middle East, where extreme climate conditions and stringent regulatory standards demand superior product reliability.
Setting the First in Fire Safety
The Class A rating, the highest fire safety classification available, confirms that LONGi modules offer maximum resistance to flame spread and external fire exposure, making them ideal for:
- Building Applied Photovoltaics (BAPV)
- Rooftop installations
- Commercial & industrial projects
- High-risk urban environments
Testing was conducted in accordance with globally recognized standards, including:
- IEC 61730-2:2023 (Fire Hazard Testing)
- ASTM E108 Fire Test
- UAE Fire and Life Safety Code of Practice (2018)
The modules successfully passed critical fire safety evaluations, including:
- MST 23: Fire Spread Test
- MST 24: Ignitability Test
- MST 25: Bypass Diode Thermal Test
- MST 26: Reverse Current Overload Test
Certified in the region for the region: Middle East Market
The Middle East, particularly the UAE, enforces some of the world’s most stringent fire safety regulations for solar systems. By securing ESL and TÜV Class A certifications,LONGi ensures full compliance with regional standards, providing developers, EPCs, and project owners with unmatched confidence.
These certifications confirm that LONGi modules are:
- Fully compliant with UAE fire safety regulations
- Engineered for extreme heat and environmental stress
- Suitable for long-term deployment across GCC markets
Advanced Engineering for Maximum Protection
LONGi’s Hi-MO modules integrate cutting-edge design and materials to achieve superior fire resistance, including:
- Dual-glass bifacial structure (2.0 mm heat-strengthened glass)
- POE-EVA encapsulation technology
- IP68-rated junction boxes
- High-grade anodized aluminium frames
This robust architecture not only enhances durability and energy yield but also ensures structural integrity under extreme fire conditions, with no flaming debris or structural failure during testing.
Driving Safe Energy Transition in the Region
As the Middle East accelerates its shift toward renewable energy, safety remains a top priority. LONGi’s Class A certified modules play a critical role in enabling secure, 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.”
