Borosil Renewables Boosts Solar Glass Output with Major Expansion

Expansion Details and Financial Snapshot

Borosil Renewables plans to significantly boost its solar glass production by adding two new furnaces, each with a 300 TPD capacity. This ₹950 crore expansion project aims to increase total output from 1,000 TPD to 1,600 TPD, a 60% jump, with full production expected by FY28. The company's market capitalization was around ₹7,587.92 crore as of May 13, 2026. While past losses affected its trailing twelve months (TTM) P/E ratio, a March 2026 P/E of 23.39 suggests current earnings are stronger. The stock has seen volatility, gaining between 1.34% and 3.76% over the past year, trading within a 52-week range of ₹374.40 to ₹721.00.

Market Growth and Policy Support

This expansion is driven by India's rapidly growing solar market, projected to become the world's second-largest by 2026 and aiming for 500 GW of non-fossil capacity by 2030. Government initiatives like PM Surya Ghar and broader industrial expansion fuel this demand. The company's move follows the government's imposition of anti-dumping duties on solar glass imports from China and Vietnam, effective December 4, 2024. Borosil Renewables previously saw its shares rise sharply on January 9, 2025, after announcing a 50% capacity expansion and the Ministry of Finance's 'Reference Price' policy, designed to protect domestic producers.

Competitive Landscape and Analyst View

Borosil Renewables currently holds about 43% of India's solar glass market and a significant 65% share in Germany through its subsidiaries. However, the competitive landscape is intensifying, with rivals like Vishakha Renewables and Triveni Renewables also announcing capacity increases. Analyst sentiment appears cautiously optimistic, with at least one 'strong buy' rating noted, though a broad consensus target price is not yet available.

Key Risks and Future Strategy

Despite the positive outlook, several risks are present. The ₹950 crore expansion project involves project management and ramp-up challenges. Margin pressure could arise during the transition period before full capacity utilization. The company's reliance on government policies like anti-dumping duties means it is vulnerable to changes in trade regulations. Potential oversupply from expanded domestic and international capacities could also affect pricing. Borosil Renewables has also faced significant charges from the insolvency of its German subsidiaries. Looking ahead, the company anticipates marginal performance improvements in FY27, with potential early commissioning of one furnace by January 2027. Borosil is also exploring entry into the rooftop solar solutions market. The expansion is funded through a mix of equity, debt, and internal accruals, aiming to secure an estimated 60% of India's domestic solar glass market by 2026.
