The global solar industry is entering a new era where manufacturing scale alone is no longer enough to establish market leadership. As photovoltaic technologies become increasingly sophisticated, manufacturers are expected to demonstrate not only production capacity but also robust research capabilities, internationally recognized testing standards, and unwavering commitment to quality.

For companies operating in highly competitive domestic and export markets, advanced laboratory infrastructure has become a strategic asset. It enables continuous product improvement, validates long-term reliability, and builds confidence among customers, project developers, certification agencies, and financial institutions.

Recognizing the growing importance of scientific validation in solar manufacturing, Rayzon Solar Limited has achieved a significant milestone by earning accreditation for its Research and Development Laboratory from the National Accreditation Board for Testing and Calibration Laboratories (NABL) under the globally recognized ISO/IEC 17025:2017 standard.

The accreditation, valid from 12 June 2026 to 11 June 2030, certifies the technical competence of Rayzon Solar's laboratory at Karanj, Surat, Gujarat, for conducting an extensive range of photovoltaic module testing according to internationally accepted standards. The achievement reflects the company's long-term investment in research, quality assurance, and technological excellence while strengthening India's expanding renewable energy manufacturing ecosystem.

Why NABL Accreditation Matters for the Solar Industry

Solar modules are designed to operate reliably for more than two decades under constantly changing environmental conditions. Throughout their lifecycle, they must withstand extreme temperatures, humidity, heavy rainfall, ultraviolet radiation, wind pressure, and mechanical stress without significant performance degradation.

To ensure this level of durability, manufacturers must conduct comprehensive laboratory testing that accurately simulates real-world operating conditions.

NABL accreditation provides independent recognition that a laboratory possesses the required technical expertise, calibrated equipment, validated methodologies, and quality management systems to produce reliable and internationally accepted testing results.

For stakeholders across the solar value chain—including EPC contractors, developers, investors, insurers, certification organizations, and end customers—this accreditation provides additional assurance that testing data can be trusted for product evaluation and decision-making.

Extensive Testing Capability Across International Standards

Rayzon Solar's accredited Research and Development Laboratory now covers 35 standardized testing methods for photovoltaic modules.

The laboratory performs evaluations based on globally accepted standards, including:

• IEC 61215 for photovoltaic module design qualification and type approval
• IEC 61730 for photovoltaic module safety qualification
• IEC TS 62804-1 covering Potential Induced Degradation (PID)
• IEC TS 63342 addressing Light and Elevated Temperature Induced Degradation (LETID)
• IEC TS 63126 for photovoltaic modules operating under high-temperature environments

Collectively, these standards form the foundation for evaluating modern photovoltaic modules before they are deployed across residential, commercial, industrial, and utility-scale solar projects.

Building Confidence Through Rigorous Reliability Testing

One of the defining characteristics of a quality solar module is its ability to maintain performance over decades despite continuous environmental exposure.

Rayzon Solar's NABL-accredited laboratory performs comprehensive reliability assessments that examine both electrical performance and structural durability.

Testing capabilities include:

• Thermal cycling to evaluate resistance against repeated temperature fluctuations
• Damp heat testing for long-term humidity exposure
• Humidity freeze testing to simulate changing climatic conditions
• UV preconditioning for prolonged ultraviolet exposure
• Mechanical load testing to assess structural integrity
• Hail impact testing to verify resistance against severe weather
• Wet leakage current evaluation for electrical safety
• Insulation resistance measurement
• Maximum power output determination
• Outdoor exposure testing and various environmental performance assessments

Together, these evaluations provide valuable scientific data that helps verify product durability, improve manufacturing consistency, and enhance long-term field performance.

A Continuous Commitment to Excellence

NABL accreditation is not a one-time certification but an ongoing process of maintaining excellence.

Throughout the accreditation period, Rayzon Solar's laboratory will continue to undergo periodic surveillance audits, technical assessments, and reassessments to verify continued compliance with ISO/IEC 17025:2017 requirements.

This continuous monitoring ensures consistent laboratory competence, equipment calibration, testing accuracy, documentation practices, and quality management systems.

Such ongoing oversight reinforces confidence that every test result generated by the laboratory continues to meet internationally accepted standards.

By combining state-of-the-art laboratory infrastructure with internationally accredited testing practices, Rayzon Solar is helping build greater confidence in Indian solar products while supporting the industry's transition toward higher quality, stronger reliability, and sustainable long-term growth.
