Alishan Green Energy, one of India’s leading encapsulant and backsheet makers, is steadily expanding its role in the country’s solar sector. In an exclusive interview with TaiyangNews at REI 2025, Dr. Khushbu Patel, AGM of Business Development, discussed the company’s recent progress and growing capabilities.
She says Alishan began operations in 2020 with a 600 MW encapsulant capacity. As the solar market expanded, the company added backsheet production in 2022 and was the first in India to introduce coated backsheets with super-hydrophobic properties. These backsheets are breathable while maintaining a low WVTR to help prevent issues such as choking or blistering.
In 2025, Alishan launched an expansion plan targeting 10 GW. By November 2025, it reached 6.6 GW of encapsulant capacity. The year also saw the introduction of 3 new products designed for the Indian market. The first was a low-acid EVA that produces 40 times less acid within a module compared to conventional EVA, improving long-term reliability.
Another new launch was Alishan’s down-conversion EPE films. According to Patel, this technology, introduced for the first time in the encapsulant segment, enables the film to contribute to power generation. In theory, it can increase output by up to 3% through UV conversion. The company believes this innovation will be well received, especially as heterojunction (HJT) and high-quality cell technologies are sensitive to UV exposure.
Patel picked Alishan’s EPE encapsulant for n-type (TOPCon) cells as its current top-selling product. It is designed to address TOPCon UVID concerns by optimizing POE thickness and adjusting EVA acidity, making it suitable for varied Indian climatic conditions, she explained.
Based on current market response, Alishan expects to reach 10 GW of encapsulant capacity by the end of next year, when Patel expects Alishan EPE and the new down-conversion films to remain its key products, which the company hopes will support more sustainable solar development in India.
