Rayzon Solar Achieves NABL Accreditation for Its R&D Laboratory
On 10 July 2026, Rayzon Solar Limited announced that its research and development laboratory located in Karanj, Surat, Gujarat, has been accredited by the National Accreditation Board for Testing and Calibration Laboratories (NABL) under the ISO/IEC 17025:2017 standard. The accreditation is effective from 12 June 2026 through 11 June 2030 and confirms the laboratory’s technical competence to conduct a comprehensive suite of photovoltaic (PV) module tests in line with internationally recognised standards.
The NABL‑accredited facility is authorised to perform 35 distinct testing methods covering design qualification, safety, and durability of PV modules. Core standards applied include IEC 61215 for design qualification and type approval, IEC 61730 for safety qualification, 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 high‑temperature operating conditions. These standards collectively provide a framework for assessing long‑term performance and operational safety before modules are deployed.
In addition to the standardised qualification tests, the laboratory conducts an extensive range of environmental, electrical, and mechanical assessments that simulate decades of field exposure. The test portfolio comprises thermal cycling, damp‑heat exposure, humidity‑freeze testing, UV pre‑conditioning, mechanical load assessments, hail‑resistance testing, wet leakage current evaluation, insulation performance testing, maximum power determination, outdoor exposure studies, and other reliability assessments covering critical operational parameters. The data generated from these tests enable engineers to optimise module design, verify manufacturing consistency, and identify improvement opportunities prior to commercial production.
By establishing in‑house, NABL‑accredited testing capabilities, Rayzon Solar can accelerate research and development cycles, perform design verification, material evaluation, and comparative studies without depending on external laboratories. This integrated approach shortens development timelines, supports faster commercialisation of new products, and upholds internationally recognised quality standards. The company asserts that the investment strengthens its quality‑assurance framework, delivers greater confidence to customers, and contributes to the maturation of India’s solar manufacturing ecosystem, positioning the nation as a trusted global hub for solar production.
