EMMVEE has reported achieving up to 25.4% efficiency on M10 TOPCon solar cells after successfully ramping up its new 1.4 GW production line in Bengaluru
The production line was established using equipment from German companies centrotherm, RENA Technologies, and halm, with process integration support from ISC Konstanz
It has now placed follow-up equipment orders for the German technology to support its expansion into solar cell manufacturing
Indian solar PV manufacturer EMMVEE has achieved solar cell efficiencies of up to 25.4% on M10 wafers after successfully ramping up its new 1.4 GW TOPCon solar cell production line in Bengaluru.
The company said the production line integrates equipment supplied by German firms centrotherm, RENA Technologies, and halm. While centrotherm coordinated the setup of the production line, RENA provided wet processing equipment for the same.
The ramp-up was supported by the International Solar Energy Research Center Konstanz (ISC Konstanz), which worked with the manufacturer on process integration and technology transfer.
Following the successful commissioning of the production line, the German technology providers say they have secured follow-up equipment orders worth 6 GW from EMMVEE as the latter expands its upstream manufacturing capabilities.
According to the project partners, RENA Technologies will supply additional wet-processing equipment for texturing, cleaning and glass removal processes as part of the repeat order. The tools are designed to reduce water, chemical, and power consumption while lowering operating costs.
Commenting on the milestone, centrotherm Chief Technology Officer (CTO) Helge Haverkamp said the project demonstrated the benefits of close collaboration between equipment suppliers and technology specialists.
RENA Technologies R&D Director Solar, Damian Brunner, said achieving 25.4% efficiency in a newly established production environment highlighted the role of advanced wet-processing technology and strong industry partnerships in accelerating TOPCon manufacturing.
ISC Konstanz will also serve as the integrator for the EMMVEE project, and claims to have an order book of approximately 20 GW in India through its consortium with centrotherm and RENA.
At the end of March 2026, EMMVEE’s installed manufacturing capacity for solar modules was 10.3 GW and 2.94 GW for solar cells. It plans to set up a 6 GW integrated cell and module facility going forward. By FY2028, it aims to increase the capacity to 16.3 GW for modules and 8.94 GW for cells (see Emmvee Doubles Revenue In FY26; 193% Surge In Profit).
