Germany-based solar cell manufacturing equipment supplier RENA Technologies has signed a contract with Emmvee Energy to supply solar cell production equipment with a total manufacturing capacity of 6 GW.
The order will support the production of Emmvee’s tunnel oxide passivated contact (TOPCon) solar cells.
Emmvee Energy is a subsidiary of Bengaluru-based solar module and cell manufacturer Emmvee Photovoltaics Power.
According to RENA, the scope of supply includes multiple units of its BatchTex 3 N600, InEtchSide 4+ BSG, InEtchSide 4+ PSG, BatchEtch 3 N600, and BatchPolyClean 3 N600 equipment. Such systems are designed for large-scale solar cell manufacturing.
The contract also includes wastewater management systems integrated with each production unit. RENA said the systems are intended to support environmental compliance and reduce wastewater treatment requirements associated with manufacturing operations.
In addition to equipment supply, the agreement includes a service package covering on-site and remote technical support, training programs, spare parts supply, and access to RENA’s spare parts warehouse in Chennai, India.
The project will be executed in collaboration with Centrotherm and ISC Konstanz. RENA said the partners will contribute expertise toward the delivery of the production solution.
The announcement comes against the backdrop of the Ministry of New and Renewable Energy mandating that solar cells be sourced from the Approved List of Models and Manufacturers List-II.
In the fourth quarter (Q4) of the financial year (FY) 2026, Emmvee Photovoltaic Power reported revenue of ₹17.39 billion (~$184 million), up 62% year-over-year from ₹10.72 billion (~$113.4 million).
In Q4 FY 2026, Emmvee increased its installed manufacturing capacity to 10.3 GW for solar modules and 2.94 GW for solar cells. Module production reached 2,999 MW, while cell production stood at 1,520 MW for the year.
The company commissioned two 2.5 GW solar module manufacturing lines during the year, supporting capacity expansion and scale-up. It also reported solar cell utilization of approximately 79% in Q4.
Emmvee’s order book increased to 9.4 GW at the end of Q4, with order inflows of 1.27 GW during the fourth quarter, providing visibility for future growth.
In December 2025, Emmvee Energy entered into a supply agreement with a domestic buyer for the offtake of 4.5 GWp of TOPCon crystalline silicon solar cells.
