Renewsys announces giga-scale expansion of solar encapsulant and backsheet manufacturing


Solar manufacturer Renewsys India has announced plans to increase its solar cell encapsulant annual manufacturing capacity to 3 GW. The company, which currently boasts 1.65 GW of encapsulant production lines, will also expand its backsheet output, from 3 GW to 4 GW.

Renewsys CEO Avinash Hiranandani said: “The Indian solar industry is growing at a steady pace. However, to be competitive, we need indigenous manufacturing to keep up with global advances in technology in both the PV module and PV component manufacturing areas. The encapsulant and backsheet components of a module have a significant role in the performance and life of solar modules. Our investments in technology, R&D and capacity expansion will help India and Renewsys maintain the foothold we have established as a key player in the global market.”

Solar cell encapsulants such as ethylene-vinyl acetate (EVA) and polyolefin elastomer (POE) sheets are polymer-based components used in PV modules to seal in solar cells by supplying adhesive and cushioning functions. The sheets are essential components that keep the glass, cells and backsheets integrated and support modules mechanically.

Renewsys claims to be India’s largest producer of indigenously-formulated encapsulants and backsheets and says it is among the top five manufacturers worldwide. Its Bengaluru factory has supplied around 9 GW of encapsulants and backsheets since opening in 2012. The plant also boasts India’s only NABL [National Accreditation Board for Testing and Calibration Laboratories]-accredited encapsulant and backsheet testing facility.
