Market Driver

"Government Regulations and Incentives"

Government regulations and incentives are essential drivers of growth in the photovoltaic (PV) module testing and certification market. These regulations ensure that solar modules adhere to stringent safety, performance, and environmental standards, essential for reliable and safe solar installations.

Standards such as IEC 61215 (performance) and IEC 61730 (safety) require comprehensive testing and certification of solar modules before they are brought to market, thereby enhancing consumer protection and ensuring quality assurance.

Furthermore, many countries impose certification requirements, such as the CE marking within the European Union and the UL listing in the United States, to confirm compliance with local regulatory standards. This further stimulates the market for PV module testing and certification.

• In December 2024, Saatvik Solar announced that its TOPCon (Tunnel Oxide Passivated Contact) modules have been certified by the Bureau of Indian Standards (BIS). This certification sets new benchmarks for solar technology in India.

Market Challenge

"Lack of Standardization Across Markets"

The lack of standardization across markets presents a considerable challenge within the photovoltaic (PV) module testing and certification market. While international standards such as IEC 61215 and IEC 61730 provide a foundational framework for assessing module performance and safety, individual countries often implement their own specific certification requirements.

For example, in the European Union, compliance with CE marking standards is mandatory, whereas, in the United States, UL certification is typically required. Furthermore, emerging markets like India adhere to local standards established by the Bureau of Indian Standards (BIS).

This variability in certification requirements results in a complex and fragmented landscape for manufacturers, who navigate numerous testing protocols and certification processes to effectively market their products globally.

To tackle the lack of standardization in the photovoltaic (PV) module testing and certification industry, a collaborative approach is crucial. Harmonizing global standards through organizations like the International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL) can create universal guidelines for performance, safety, and quality.

This would allow manufacturers to meet consistent criteria across regions, reducing complexity and certification costs. Mutual Recognition Agreements (MRAs) between governments and certification agencies can further streamline the process by recognizing PV modules certified in one region across others, eliminating redundant testing. Promoting international cooperation on testing protocols will encourage consistent product quality and regulatory transparency.

Market Trend

"Advancement in Testing Technologies"

Recent advancements in testing technologies are enhancing the accuracy and reliability of photovoltaic module testing and certification market. Techniques like electroluminescence (EL) imaging and infrared thermography effectively detect internal defects, such as microcracks and degradation, that are not visible externally.

As bifacial solar modules gain popularity, new methods are being developed to assess their performance under varying real-world conditions. Improved thermal cycling and damp heat tests allow manufacturers to better understand the durability of solar panels over long-term environmental exposure. These innovations are vital for ensuring that future solar products meet higher standards for performance, efficiency, and longevity.

• In March 2024, MBJ Solutions introduced its new MBJ Module Tester, designed to simplify the process of PV module recycling. This innovative tool allows for efficient testing of solar modules at the end of their life cycle, helping to assess their potential for reuse or recycling, thereby supporting sustainability efforts in the solar industry and promoting a circular economy for photovoltaic technology.
