Rayzon Solar’s research and development laboratory in Surat, Gujarat, has received accreditation from the National Accreditation Board for Testing and Calibration Laboratories (NABL) under the ISO/IEC 17025:2017 standard, strengthening its in-house photovoltaic (PV) module testing capabilities.

The accreditation, valid from June 12, 2026, to June 11, 2030, covers the company's laboratory at Karanj in Surat district and certifies its technical competence to conduct 35 testing methods for solar PV modules in accordance with internationally recognised standards.

The accredited scope includes testing under IEC 61215 for module design qualification and IEC 61730 for safety qualification, along with 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.

The facility is equipped to conduct a range of performance and reliability tests, including thermal cycling, damp heat exposure, humidity freeze, ultraviolet preconditioning, mechanical load, hail resistance, insulation performance, wet leakage current, maximum power determination and outdoor exposure, the company said.

Rayzon Solar said the accreditation would enable it to carry out internationally recognised testing in-house, reducing dependence on external laboratories while accelerating product development, material validation and reliability studies.

The company added that the accredited laboratory would support the development and qualification of advanced photovoltaic technologies and next-generation solar modules as the industry increasingly focuses on higher efficiency and long-term reliability.

The accreditation also comes as India's solar manufacturing sector expands capacity and seeks to strengthen quality infrastructure to improve export competitiveness and product reliability.

NABL accreditation requires laboratories to undergo periodic surveillance and reassessment to ensure continued compliance with ISO/IEC 17025:2017 standards for testing competence, calibration traceability and quality management.

Rayzon Solar said the certification reinforces its investment in research, development and quality assurance as demand for high-performance and bankable solar modules continues to grow in domestic and international markets.
