Indosol Solar to Establish Vertically Integrated 5 GW Solar Manufacturing Hub

Indosol Solar, a subsidiary of Andhra Pradesh-based Shirdi Sai Electricals (SSEL) Group, aims to establish 1 GW of ingot-to-module manufacturing capacity by the end of 2025, with plans to expand this to 5 GW by October 2026.

The company is setting up a vertically integrated solar photovoltaic (PV) manufacturing facility at Ramayapatnam, under India’s Production Linked Incentive (PLI) scheme, covering the entire value chain from quartz to finished module. “By December, we’ll begin producing 1 GW from ingot to module at our pilot plant, which will serve as a training and operations hub,” said Visweswara Reddy, Chairman and Managing Director of SSEL Group.

As part of the next phase, Indosol Solar will add a 1,200-tonne-per-day (TPD) glass manufacturing unit. By February–March 2027, the company targets a 10 GW manufacturing capacity spanning ingot, wafer, cell, and module production. Upstream operations, including polysilicon production, are expected to commence by late 2027.

On land acquisition, Reddy noted that initial approvals under the previous administration secured 29 acres, while the current government, led by N. Chandrababu Naidu, facilitated the allocation of an additional 114 acres — adequate for the 1 GW facility. Major land handovers are anticipated by May 2025, with full possession by August 2025.

The acquired land will host a fully integrated solar PV manufacturing complex, with long-term plans to build 30 GW of capacity, including facilities from metallurgical silica to polysilicon and glass, and infrastructure for ancillary units.
