New Delhi: Tanfac Industries Ltd., one of India’s leading fluorine chemical manufacturers, has successfully commissioned the second phase of its Solar Grade Dilute Hydrofluoric Acid (DHF) plant in Chennai, marking a major milestone in India’s solar energy supply chain. The new 5,000 TPA (AHF Basis) unit was commissioned on October 6, 2025, following the successful trial production and customer quality approvals.
With this expansion, Tanfac’s total Solar Grade DHF capacity now stands at 10,000 TPA (AHF Basis), making it the only Indian chemical company to operate such a facility. The first phase of the project, also with a capacity of 5,000 TPA, was commissioned in June 2025. Together, the two phases represent a strategic leap in India’s ability to supply high-purity chemicals critical to solar energy production.
The Solar Grade DHF produced by Tanfac meets stringent quality standards required by major solar energy manufacturers, reinforcing the company’s position as a trusted supplier in the clean energy ecosystem. The product is essential for photovoltaic cell manufacturing, where chemical purity directly impacts efficiency and performance.
Speaking on the occasion, Director Afzal Malkani stated, “We are excited to announce the successful commissioning of the second 5,000 TPA solar grade DHF plant after successfully commissioning the first phase in June 2025. The product from the new line also conformed to the stringent quality requirements of its major and key solar energy producing customers. Tanfac is the first and only chemical company in India to achieve this. This is another milestone in the history of Tanfac and has the potential of increasing the top and bottom lines significantly.”
The expansion was completed within an implementation window of 8–12 months, demonstrating Tanfac’s operational efficiency and commitment to timely delivery. The move is expected to significantly boost the company’s financial performance while strengthening India’s domestic supply of critical solar-grade chemicals.
Under Regulation 30 of SEBI LODR, the company disclosed the following:
- Existing capacity before expansion: 5,000 MT per annum (AHF Basis)
- Revised capacity after expansion: 10,000 MT per annum (AHF Basis)
- Implementation period: 8–12 months
Tanfac’s achievement comes at a time when India is aggressively expanding its solar energy footprint, with ambitious targets under the National Solar Mission. By localizing the production of high-purity DHF, Tanfac is helping reduce import dependence and enabling faster, more cost-effective solar infrastructure development.
The commissioning also reflects the company’s long-term strategy to align with India’s clean energy goals and contribute to the global push for decarbonization. As demand for solar components surges, Tanfac’s expanded capacity positions it as a key enabler of sustainable growth in the renewables sector.
This development not only strengthens Tanfac’s market leadership but also signals a broader shift in India’s chemical manufacturing capabilities—toward high-tech, high-purity, and energy-aligned production.
