Borosil Renewables to invest ₹950 crore to expand solar glass unit in Gujarat by 600 TPD 

Borosil Renewables Ltd has laid the foundation stone for a ₹950-crore expansion project in Gujarat that will increase the company’s solar glass production capacity by 600 tonnes per day (TPD) from the third quarter of financial year 2026-27. The Centre has announced a definitive anti-dumping duty on all imports of solar glass originating in or exported from China and Vietnam for a period of five years,

“We had a plan that was discussed 2-3 years ago. Unfortunately, the anti-dumping duty which was previously in place had lapsed, and so due to increased competition, we were not in a position to consider expansion. After imposition of a provisional anti-dumping duty on imports of solar tempered glass from China and Vietnam in December 2024, we decided to go ahead to revive our expansion plan,” Pradeep Kheruka, Chairman, Borosil Renewables Ltd told businessline. The expansion project, which will be commissioned between October-December 2026, will take the total installed capacity of the unit in Bharuch district to 1600 TPD.

The previous plan of the company to expand the unit by 500 TPD has now been revised to 600 TPD. “The domestic demand for solar glass is twice that being produced in India. Because of the prevailing low prices of solar glass, it was not viable for us to set up a new production line. Now, prices have become viable,” Kheruka added. The imposition of anti-dumping duty for a period of five years, effective from December 4, 2024, on the import of solar glass from China and Vietnam, is expected to establish a level playing field for domestic manufacturers.

Borosil Renewables has more than 40 per cent of the market share of solar glass produced in India. The present solar glass capacity in the country is 2,300 tonnes per day, which is 40 per cent of the domestic demand. Despite the domestic manufacturing capacities, India currently imports about 3000 TPD of solar glass.

“Domestic demand continues to be robust. Manufacturing capacity for solar modules has already reached 90-plus gigawatts and is expected to rise to 150 gigawatts by March 2027. The country has seen its highest ever solar installations at 25 gigawatts, which means module consumption of about 35 gigawatts in the year just completed, as against 15 gigawatts during the previous year. We expect the installations to rise to 40 to 45 gigawatts annually, going forward. Use of locally produced modules has risen sharply after the implementation of the ALMM (Approved List of Models and Manufacturers) mechanism from April 2024, which has led to increased demand for all components, including solar glass,” Kheruka said during a recent earnings call hosted by the company.
