Kosol Energie Launches Hail-Resistant N-Type Glass-to-Glass Solar Modules

Kosol Energie, India’s Leading Solar Energy Company and a Grade-A Top Tier-1 Global Solar Module Manufacturer, has introduced its enhanced N-Type Glass-to-Glass (G2G) Solar PV Modules, engineered to deliver exceptional durability, long-term reliability, and superior performance under extreme weather conditions. Designed to withstand harsh monsoons and severe hailstorms in global markets, the new modules reinforce Kosol’s commitment to manufacturing technologically advanced and climate-resilient solar solutions.

As climate conditions become increasingly unpredictable, solar modules are expected to perform reliably under heavy rainfall, high humidity, strong winds, and hailstorms. Addressing these evolving challenges, Kosol’s latest N-Type Glass-to-Glass modules are qualified for 35 mm hail impact testing, significantly exceeding the conventional IEC qualification requirement of 25 mm hail diameter under IEC 61215:2021 standards. The modules have successfully undergone testing at a NABL-approved IEC laboratory, demonstrating enhanced resistance against glass damage and microcracks caused by hail impact.

The modules are manufactured using thermally tempered high-strength solar glass, providing improved mechanical strength and impact resistance. Their premium Glass-to-Glass (G2G) architecture offers enhanced protection against moisture ingress, environmental stress, and long-term degradation while improving overall module reliability.

To further strengthen durability, the modules utilize higher GSM POE (Polyolefin Elastomer) encapsulation, offering superior cushioning to solar cells during transportation, vibration, thermal cycling, and hail impact. The advanced encapsulation technology helps minimize mechanical stress, ensuring sustained module performance throughout its operational life.

Additionally, the modules feature high-transmission Anti-Reflective Coated (ARC) glass, enabling greater light absorption and improved energy generation while maintaining high conversion efficiency under diverse climatic conditions.
Kosol’s enhanced N-Type G2G modules have also successfully completed 3× IEC qualification testing, validating their ability to perform consistently under demanding environmental conditions and reinforcing the company’s focus on quality, reliability, and long-term energy generation.

Commenting on the launch, Kalpesh Kalthia, Chairman and Managing Director, Kosol Energie, said, “The future of solar energy depends not only on higher efficiency but also on long-term reliability under increasingly challenging weather conditions. Our enhanced N-Type Glass-to-Glass modules are engineered to deliver exceptional durability, helping customers maximize energy generation while reducing long-term operational risks. At Kosol, we continue to invest in advanced manufacturing technologies that deliver global quality standards while addressing the evolving needs of the Indian and international solar markets.”

The newly introduced modules are available in 600 Wp, 620 Wp, and 630 Wp variants and are fully compliant with IEC 61215:2021 standards. They are also available in BIS-certified DCR configurations, including G12R and G12 models, supporting the growing demand for domestically manufactured high-performance solar modules in India.

With continuous investments in advanced manufacturing, rigorous quality assurance, and product innovation, Kosol Energie remains focused on delivering next-generation solar technologies that offer higher efficiency, greater reliability, and long-term value for utility-scale, commercial & industrial, and residential solar projects across India and global markets.
