Intertek Acquires Mitsui Chemicals’ Solar Testing Lab in Gujarat
⚡ Quick Read
- What happened: Intertek Group has acquired Mitsui Chemicals India’s ISO 17025-accredited solar PV testing laboratory located in Ahmedabad, Gujarat.
- Why it matters: The acquisition provides local solar manufacturers with enhanced access to BIS and IEC certification services, critical for navigating India’s stringent quality control mandates.
- Watch: Further consolidation in the quality assurance sector as India’s domestic module manufacturing capacity continues to scale rapidly.
Background and Context
As India’s renewable energy sector experiences unprecedented growth, the demand for rigorous quality assurance has become paramount. Intertek Group, a global leader in assurance, testing, inspection, and certification, has strategically expanded its footprint in the region by acquiring the assets of Mitsui Chemicals India’s solar photovoltaic (PV) testing laboratory in Ahmedabad, Gujarat. This move aligns with the increasing focus on technical excellence within the Indian solar manufacturing ecosystem.
Key Details
The newly acquired facility is an ISO 17025-accredited laboratory capable of providing comprehensive testing services for solar installations, materials, and components. Beyond standard performance testing, the lab is equipped to facilitate Bureau of Indian Standards (BIS) and International Electrotechnical Commission (IEC) conformity assessment programs. By integrating this facility into its global network of over 1,000 laboratories, Intertek aims to streamline the certification process for Indian manufacturers, enabling faster access to both domestic and international markets.
This acquisition follows Intertek’s February 2026 purchase of Aerial PV Inspection, signaling a broader strategy to dominate the solar quality assurance vertical. The timing is significant; in 2025, the Ministry of New and Renewable Energy (MNRE) issued revised guidelines for the series approval of solar modules, mandating strict performance and safety testing under the ‘Solar Systems, Devices and Components Goods Order, 2025.’
What This Means for EPCs and Developers
For EPC contractors and solar developers, the availability of high-quality, local testing infrastructure is a critical risk-mitigation tool. With India adding a record 36.6 GW of solar capacity in 2025—a 43% increase over the previous year—the pressure on supply chains to maintain quality is immense. Recent reports, including Kiwa PI Berlin’s 2025 PV Module Manufacturing Quality Report, indicate that rapid capacity expansion has led to defect rates exceeding 8% in some regions. Access to Intertek’s harmonized testing services will allow developers to ensure that the modules procured for their projects meet rigorous safety and efficiency standards, thereby protecting long-term project bankability and operational stability.
What Happens Next
The integration of this lab into Intertek’s portfolio is expected to enhance the reliability of the domestic supply chain. As India continues to scale its solar manufacturing base—having added nearly 119 GW of module capacity in 2025—the focus will shift from sheer volume to quality control and operational longevity. Industry stakeholders should monitor how this increased testing capacity influences the enforcement of BIS standards and whether it leads to a reduction in module defect rates across upcoming utility-scale projects in the broader India renewable energy sector.
