Rayzon Solar Limited has achieved a significant milestone in its commitment to quality, innovation, and technical excellence by receiving accreditation for its Research and Development Laboratory from the National Accreditation Board for Testing and Calibration Laboratories (NABL) under the internationally recognised ISO/IEC 17025:2017 standard.
The accreditation, valid from 12 June 2026 to 11 June 2030, recognises the technical competence of Rayzon Solar’s testing laboratory in Karanj, Surat, Gujarat, for conducting a comprehensive range of photovoltaic (PV) module testing in accordance with globally accepted standards.
The accredited laboratory covers 35 testing methods for solar photovoltaic modules, encompassing the critical requirements of IEC 61215 for module design qualification and IEC 61730 for safety qualification. The scope also includes advanced reliability assessments under IEC TS 62804-1 for Potential Induced Degradation (PID), IEC TS 63342 for Light and Elevated Temperature Induced Degradation (LETID), and IEC TS 63126 for module qualification under high-temperature operating conditions.
These capabilities enable comprehensive evaluation of solar modules through tests such as thermal cycling, damp heat exposure, humidity freeze, UV preconditioning, mechanical load testing, hail resistance, insulation performance, wet leakage current, maximum power determination, outdoor exposure, and other critical reliability assessments that determine long-term field performance.
The NABL accreditation represents far more than a compliance milestone. It establishes Rayzon Solar’s laboratory as a technically competent facility capable of generating internationally recognised testing data, reinforcing confidence among customers, EPC companies, financial institutions, and certification bodies.
By bringing this extensive testing capability in-house, Rayzon Solar can significantly accelerate product development cycles. Design improvements, material evaluations, and reliability studies can now be validated internally through NABL-accredited testing, reducing dependence on external laboratories while enabling faster innovation and more efficient product qualification.
The achievement also strengthens the company’s ability to support evolving photovoltaic technologies, including advanced cell architectures and next-generation module designs, where continuous validation and reliability testing have become increasingly important.
For the broader Indian solar manufacturing industry, the accreditation reflects the country’s growing emphasis on developing world-class quality infrastructure alongside expanding manufacturing capacity. As India continues its journey toward becoming a global renewable energy manufacturing hub, internationally accredited testing facilities play a vital role in enhancing product reliability, strengthening export competitiveness, and building long-term market confidence.
Importantly, NABL accreditation is an ongoing commitment rather than a one-time recognition. The laboratory will continue to undergo periodic surveillance and reassessment throughout the accreditation period to ensure continued compliance with ISO/IEC 17025:2017 requirements, maintaining the highest standards of testing competence, calibration traceability, and quality management.
This latest achievement reinforces Rayzon Solar’s long-term vision of combining manufacturing excellence with robust research, development, and quality assurance capabilities. By investing in internationally recognised state-of-the-art testing infrastructure, the company is strengthening its ability to deliver high-performance, reliable solar modules while contributing to the advancement of India’s rapidly growing solar manufacturing ecosystem.
As the demand for durable, bankable, and high-efficiency solar modules continues to rise globally, Rayzon Solar’s NABL-accredited Research and Development laboratory positions the company to support customers with technically validated products backed by internationally recognized testing standards.
