Vikram Solar opens 5 GW plant in Vallam, reaches 9.5 GW capacity

Vikram Solar has announced the commissioning of its new manufacturing facility in Vallam, Tamil Nadu, with an annual module production capacity of 5 GW. This facility brings the company’s total capacity to 9.5 GW, strengthening its position among India’s leading solar photovoltaic manufacturers. The project is part of the company’s broader strategy to scale up domestic production capacity in response to rising solar energy demand.

A facility designed for large-scale automated manufacturing

The Vallam plant spans 27,000 square metres and is built on a fully automated industrial architecture, combining intelligent robotics, advanced material handling systems, integrated quality control processes and automated packaging. It features Tunnel Oxide Passivated Contact (TOPCon) technology, compatible with M10, G12 and G12R formats, and designed for future upgrades to Heterojunction Technology (HJT).

This level of automation aims to improve manufacturing precision, reduce defect rates, and ensure more stable and predictable output. The modules meet Tier-1 and international quality standards. Efficiency gains are expected to increase the company’s competitiveness in the domestic market while offering shorter delivery timelines for developers and commercial clients.

Strengthening industrial presence in Tamil Nadu

The Vallam launch is part of a regional consolidation strategy, complementing the existing Oragadam site and the under-construction Gangaikondan facility. These industrial locations aim to establish an integrated solar manufacturing hub in Tamil Nadu, a key state for renewable energy development in India.

Modules from the Vallam plant will serve utility-scale developers, commercial and industrial (C&I) customers, and distributed generation projects. Process standardisation is expected to ensure higher performance, longer durability, and improved reliability for large-scale applications.

Expanded capacity and local growth outlook

The company has stated its objective to achieve 40% to 50% workforce diversity at the Vallam site, as part of its inclusive industrial development policy. This approach supports the development of local skills in automation and high-tech manufacturing while building a skilled labour base in the region.

The investment in the Vallam plant reflects Vikram Solar’s commitment to building a sustainable manufacturing base in India, aligned with the country’s growing demand for photovoltaic modules. This industrial expansion follows the medium-term growth dynamics of the Indian solar market, which continues to attract value chain investments.
