Recently, Solex Energy, an Indian solar module manufacturer, announced plans to invest about $1 billion in solar module and battery capacity expansion.

As part of its "Vision 2030" strategy, Solex Energy will "explore" the construction of a 2GW solar cell production plant and plans to increase its capacity to 5GW. At the same time, the company will expand its component capacity tenfold, from 1.5GW to 15GW. The company said that would require adding about 25,000 employees.

Both cells and modules will use rectangular solar cells to produce N-type TOPCon technology products. These products will be used in Solex Energy's new TPI-R series, which is an 182.2 x 210mm module consisting of 132 half-cells with a power output of up to 625Wp and a conversion efficiency of 23.14%. The new components will be double-sided and designed for deployment in large ground-based power plant projects.

Chetan Shah, Chairman and managing Director of Solex Energy, said: "Vision 2030 is an important milestone in our journey to become a fully integrated solar company. With the introduction of the N-type TOPcon technology with rectangular cells, SolexEnergy is raising the bar for efficiency and reliability."

In recent weeks, India has made a number of announcements regarding TOPCon's battery capacity. Gautam Solar last month revealed plans to build a 2GW TOPCon battery production plant in northern India, while Indian energy conglomerate Jakson Group plans to build 2.5GW of battery capacity at an unspecified location.

In addition, Adani Group, the largest player in the Indian solar industry, told PV Tech that it is planning to achieve 10GW of vertically integrated domestic solar capacity, from silicon ingot to module. However, amid plummeting prices and what analysts have called a "brutal" polysilicon market, the company has reportedly decided to "refrain" from developing 10GW of polysilicon capacity.
