In a world grappling with the impact of climate change, there is an urgent need to take decisive actions to reduce carbon emissions and transition to sustainable, greener energy. The Indian government has recognised this necessity, setting ambitious renewable energy targets, including 300 GW of solar power by 2030. Contributing to this goal, Novanext Energies Pvt. Ltd. is making a mark with its state-of-the-art solar backsheet manufacturing plant.

A Humble Beginning with Big Ambitions
Promoted by a group of seasoned entrepreneurs with over 75 years of combined experience, Novanext Energies is poised to make a substantial impact. The company is starting its journey with the installation of India's first state-of-the-art PV solar backsheet manufacturing plant. This plant, featuring the widest width of 1600mm for solar backsheets, represents just the beginning. With a clear vision to move up the value chain, Novanext aims to expand its offerings, driving greater environmental impact as it grows.

As its name suggests – ‘Novanext’ meaning ‘New + Next’- the company is committed to being a leader in innovation. Their latest achievement is bringing the technology of fluoro-coating on solar backsheets to India for the first time. This advanced coating enhances the backsheet's durability and performance, making it ideal for the next generation of PV solar modules, particularly those that require backsheets as wide as 1600mm. Novanext's commitment to high-quality standards extends beyond just their products - it's embedded in every aspect of the company’s operations.

Novanext Energies has introduced its newly developed high water-resistant transparent backsheet. Specially designed for N-type TOPCon and HJT cells, this backsheet addresses two major challenges faced by these solar modules: cell blackening and rapid power degradation under humid and hot conditions. This solution is a testament to Novanext's innovative approach and dedication to solving critical industry pain points.

Key Features of Novanext’s New Low WVTR Backsheet
The new backsheet is packed with advanced features, making it a game-changer for the solar industry:

Excellent light-shielding properties with uniform pigment distribution.
Superior resistance to UV aging and damp-heat aging, ensuring long-lasting durability.
Low Water Vapour Transmission Rate (WVTR) of less than 0.1 g/m² per day, providing excellent moisture resistance.
Strong adhesion to EVA/POE film, essential for stable module construction.
High retention of water permeability at elevated temperatures, maintaining performance even after extensive damp-heat treatment.

The backsheet's ability to withstand extreme conditions, such as 2000 hours of damp-heat testing with minimal yellowing, makes it a standout choice for the most demanding solar applications. Additionally, the customisable low WVTR range (0.1-0.001 g/m² per day) allows manufacturers to tailor the product to specific requirements, offering flexibility and enhanced performance.

Moving Beyond Glass in Solar Modules
While glass has long been a popular material for photovoltaic (PV) module backsheets, it comes with several drawbacks that Novanext’s backsheet aims to overcome. Glass is heavier and more fragile, leading to increased installation costs, especially for rooftop systems. Its higher thermal conductivity can also result in heat loss in colder climates, reducing the efficiency of solar panels. Furthermore, glass offers limited flexibility and design options, making it less versatile for various solar applications.

Novanext’s polymer-based backsheet, by contrast, offers significant advantages, including lightweight construction, greater flexibility, and enhanced durability, addressing many of the limitations posed by glass. By bringing in the latest innovations, including fluoro coating and wide-width backsheets, the company is well-positioned to meet the evolving needs of the solar industry, particularly as it moves towards N-type TOPCon and HJT cells.
