As demand for clean, renewable energy continues to grow, PV module manufacturing has become a vital part of the global energy market. This growth has, in turn, led to increased competition as more players enter the renewable energy space.
In this increasingly competitive market, meeting industry standards and certification requirements is crucial for any solar manufacturer.
This article discusses the significance of certifications and regulations in the solar energy industry, covers the major certification bodies and their standards, and explores both the benefits and challenges of obtaining them.
Why Are Certifications Required for PV Module Manufacturing?
Certifications serve as official recognition that a product meets specific industry standards. In many cases, they are mandatory requirements manufacturers must meet to guarantee the safety and quality of their products.
For manufacturers, meeting these standards and certification requirements is crucial for several reasons.
- Certifications act as badges of quality, demonstrating a manufacturer’s commitment to producing high-quality products.
- They assure customers that they are purchasing a product that meets industry standards and is safe to use.
- In some cases, certifications can give manufacturers a competitive edge by differentiating their products from the competition.
Major PV Module Certification Standards
Several certification bodies regulate the PV market by setting industry standards and requirements. The most notable are the International Electrotechnical Commission (IEC), Underwriters Laboratories (UL), and the CB Scheme.
The IEC is a global organization that develops and publishes international standards for electrical and electronic technologies, including solar PV. It has established several key standards for the industry, such as IEC 61215, IEC 61646, IEC 61730, IEC 62108, IEC 61701, and IEC 62716.
UL is an independent certification organization providing safety and quality certifications for various products, including those used in solar cell manufacturing. Its UL 1703 standard, which covers flat-plate photovoltaic modules and panels, is the primary solar panel certification for the US and Canada.
The CB Scheme is a global certification system that allows manufacturers to obtain product certifications that are recognized in multiple countries.
IEC Standards for Solar Panels
Some of the most common standards for solar cells are set by the International Electrotechnical Commission, a nonprofit that establishes international assessment standards for electronic devices, including solar modules.
To obtain certifications, manufacturers must comply with several key IEC standards. These include:
IEC 61215: This core testing standard for solar panels specifies the requirements for design qualification and approval of crystalline silicon terrestrial photovoltaic modules, especially for non-US countries.
IEC 61646: This standard specifies the requirements for design qualification and type approval of thin-film terrestrial photovoltaic modules.
IEC 61730: This standard specifies the requirements for the safety qualification of photovoltaic modules.
IEC 62108: This standard specifies the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies.
IEC 61701: This standard specifies the requirements for salt mist corrosion testing.
IEC 62716: This standard specifies the requirements for testing and evaluating the potential induced degradation (PID) resistance of photovoltaic (PV) modules.
While these are some of the most important certifications, the list is not comprehensive; other regional and country-specific standards also exist. Therefore, it’s critical to consider the target market for the solar panels.
General Standards and Regulations for Solar Manufacturing
In addition to solar-specific standards, manufacturers must also comply with broader regulations that apply to PV module manufacturing. These include:
CE Marking: The CE mark is a mandatory conformity marking certifying that a product meets European Union (EU) safety, health, and environmental protection requirements.
FCC Accreditation: The Federal Communications Commission (FCC) regulates the electromagnetic compatibility (EMC) of electronic products, including solar modules. This is a mandatory certification for electrical equipment and electronics manufactured or sold in the US.
The CB Scheme is an international system for the mutual acceptance of product safety test reports and certificates for electrical and electronic equipment, devices, and components. It is an international program operated by the International Electrotechnical Commission for Electrical Equipment (IECEE).
Location-Specific Regulation and Certification
In addition to global standards, solar manufacturers must also comply with location-specific regulations and certifications.
For example, in Europe, solar modules must comply with the European Union’s Restriction of Hazardous Substances (RoHS) directive, while in the United States, manufacturers must comply with the National Electric Code (NEC) and the International Building Code (IBC).
It’s important for manufacturers to research their target market to fully understand the required certifications.
Benefits of Certification for Solar Module Manufacturers
Certifications play a crucial role in the reputation and brand management of solar PV production companies. They demonstrate a commitment to quality, helping to build trust and credibility with customers.
Furthermore, since certifications are a legal requirement in some markets, they can grant manufacturers access to new customers and renewable energy markets.
Challenges in Obtaining Certifications and Regulations
While essential, obtaining the necessary certifications can be challenging for solar module manufacturers. The process is often time-consuming and expensive, requiring products to meet strict industry standards.
Location-specific regulations add another layer of complexity, as manufacturers must comply with different requirements for each market.
Conclusion
Nearly every industry is governed by regulations or minimum standards that its players must follow. In this sense, solar PV module manufacturing is no different from construction, consumer products, or even service industries like tax consultancy.
Although obtaining certifications can be a hurdle, it is a necessary step for producing and marketing solar products.
Certification not only provides a competitive advantage but is also mandatory in some cases. It is therefore essential to research the standard requirements for a target market before beginning PV manufacturing.
