Recently, Indian solar module manufacturer Solex Energy announced the signing of a Memorandum of Understanding (MoU) with Germany’s International Solar Energy Research Center Konstanz (ISC Konstanz). The two parties will collaborate to develop advanced solar cell manufacturing technologies.
According to the agreement, the renowned European solar research institute ISC Konstanz will provide comprehensive technical support to Solex Energy, primarily focused on three key areas: upgrading Solex’s upcoming TOPCon cell production line; jointly researching and developing Back Contact (BC) technology and perovskite/silicon tandem solar technology; and assisting Solex in establishing its internal R&D system. Additionally, ISC Konstanz will grant access to its patent portfolio to foster local solar innovation in India.
Chetan Shah, Chairman and Managing Director of Solex Energy, stated that this collaboration is a crucial step towards technological excellence and global leadership. “Under our Vision 2030, we plan to establish India as a hub for solar innovation, targeting a valuation of 1 billion Rupees and building a highly skilled team of 25,000 professionals,” Shah said.
This technical partnership is backed by Solex’s large-scale expansion plan. The company intends to invest $1.5 billion over the next five years to expand its manufacturing capacity, with a focus on increasing its export share to the US market. Its Vision 2030 clearly outlines goals to build 10 GW of solar module and 10 GW of solar cell manufacturing capacity. It is worth noting that Solex demonstrated its commitment to technological breakthroughs by launching India’s first rectangular cell-powered solar module during the 2024 Renewable Energy India Expo.
Industry analysis suggests that this Indo-German technological collaboration not only provides technical support for Solex’s expansion into international markets but is also expected to accelerate India’s transition from a solar manufacturing country to an innovation hub, potentially introducing new variables into the global solar industry landscape.
