For this, Emmvee is setting up a new plant in Karnataka with an investment of ₹5,500 crore.
As a part of backward integration, the company will also set up a 9 GW ingot and wafer manufacturing facility, for which the location has not yet been finalised. The facility will be commissioned in two phases, with 5 GW scheduled for FY29 and the remaining 4 GW for FY30. The total capital expenditure for the project is estimated at ₹ 5,000–5,500 crore.
Gautam Solar to invest ₹4,000 Cr for Cell, Ingot and Wafer Manufacturing
Gautam Solar outlined its plans to establish a solar cell, ingot, and wafer manufacturing plant in Madhya Pradesh with an investment of ₹4,000 crore.
At the REI expo, a representative of the company mentioned that the upcoming facility will support backward integration for Gautam Solar’s existing solar module manufacturing plants in Bhiwani and Haridwar.
The new plant will be developed in phases, with the first phase covering solar cell manufacturing and the second phase adding ingot and wafer manufacturing lines.
At the expo, Gautam Solar also displayed other products, including distribution boxes, inverters, Battery Energy Storage Systems (BESS), and a 640 Wp solar module launched at the previous edition of the event.
Saatvik Launches 640 Wp Solar Module
Saatvik Green Energy Ltd., an Indian renewable energy company headquartered in Gurugram, launched 640 Wp G12 R TOPCon solar module at REI Expo 2026. The module has an efficiency of 23.69% and features 132 rectangular solar cells.
These newly launched modules are being manufactured at the company’s plant in Odisha, and Saatvik expects to begin supplying them in November 2026.
Saatvik Green Energy is targeting a solar module manufacturing capacity of 8.8 GW by the end of FY27, up from the current capacity of 4.8 GW.
Also, the company will be entering the energy storage segment next year. According to a company spokesperson, Saatvik will manufacture BESS at its plant in Ambala.
Inox Solar Targets Jan 2027 for Solar Cell Production
Inox Solar is setting up a solar cell, ingot, and wafer manufacturing plant in Odisha. The solar cell manufacturing line is expected to be commissioned by January 2027, while the ingot and wafer manufacturing lines are scheduled to be commissioned over the next two years.
Further, the company will also be foraying into inverter and BESS manufacturing segment in 2027. Speaking with CableCommunity, a company representative said that Inox Solar will establish a new plant for manufacturing inverters and energy storage systems. However, the location for the plant has not been finalised, although Gujarat is being considered.
BESS Manufacturing and Storage Technologies Gain Ground at REI 2026
Raydean Showcases Ray-Batt Storage System, Microinverters
Raydean Enterprises Limited, a Jaipur-based manufacturer of renewable energy equipment, showcased its recently launched Energy Storage System and microinverters at the expo.
Mr. Praveen Mishra, Senior Manager at Raydean Enterprises, told the team of CableCommunity that the Energy Storage System, namely Ray-Batt, includes a lithium-based energy storage system with a storage capacity of up to 50 kWh. This system is available in rack-mounted, wall-mounted, and wheeled lithium battery configurations to fit in different installation spaces.
Further, the company’s newly launched microinverters are available in 1 KW and 2 KW power output capacities. These solar microinverters are specifically designed for balcony power plants and residential rooftop systems. Raydean is also developing hybrid inverters with an output capacity of up to 10 KW.
Waaree Commissions ₹8,000 Crore BESS Manufacturing Plant
Waaree Group has recently commissioned a new BESS container manufacturing plant in Gujarat with a total annual capacity of 5.15 GWh. This marks the first phase of the company’s plan to reach 20 GWh of storage capacity, a plan backed by an investment of ₹8,000 crore.
In a conversation with CableCommunity, a company representative discussed Waaree’s expansion beyond solar and BESS manufacturing. The representative added that Waaree is exploring opportunities in semiconductor manufacturing and green hydrogen, although further details have not yet been disclosed.
Additionally, Waaree has also recently acquired a stake in a smart meter manufacturing company based in Greater Noida.
Vikram Solar Targets LFP Cell Manufacturing by FY29
Vikram Solar, a Kolkata-based solar energy company, displayed its 650 Wp, 670 Wp, and 720 Wp solar modules at REI Expo 2026.

REI 2026 Signals Shift Towards Integrated RE Manufacturing
REI Expo 2026 reflected a widening of India’s domestic renewable-energy manufacturing ambitions. While solar module capacity continues to expand, manufacturers are increasingly moving towards backward integration into cells, ingots and wafers, alongside investments in BESS and battery-cell manufacturing. The announcements indicate an industry moving towards a more integrated domestic renewable-energy supply chain
Also, the expo has been renewed for its next edition (20th edition), which will be held on 4th to 6th November 2027 at the India Expo Mart, Greater Noida.
