It’s important to explore another aspect of solar certifications: solar panel certification. Today, quality solar panels must meet various standards. If you are considering running a solar business and selling panels, you must know which solar panel tests guarantee solar panel reliability.

Let’s delve into the specifics of solar panel testing and the international standards involved in this part of the solar industry.

The Importance Of Solar Panel Testing

Testing solar panels is a common practice as it ensures a module’s quality and safety. Quality solar panels do have a long lifespan. If properly built and installed, equipment should generate usable electricity for over 25 years. These numbers are striking. Just considering the longevity of such an investment, people want to ensure solar panel reliability. Thus, they expect any equipment on their roof to perform well and operate safely after all solar panel tests are carried out.

What Solar Certification & Testing Are Important in the Solar Industry

With solar energy getting more popular, some governments and utility companies have introduced new regulations that require any grid-tied solar equipment to hold specific solar certifications. Below, you may get familiar with the most common solar certifications that prove solar panel reliability and quality.

The Most Common Solar Panel Testing and Solar Certifications

When checking a solar panel spec sheet, you’ll spot acronyms and numbers under safety and rating certifications. Wondering what these mean? Here are some common solar panel testing norms and certifications for comparing panels. If you’re eyeing a career in solar energy, understanding these standards is key. Let’s decode these terms together.

IEC: International Electrotechnical Commission

It is the foremost global organization dedicated to developing and disseminating international standards encompassing all electrical, electronic, and related technologies, including photovoltaic (PV) panels. This organization neither carries out solar testing nor module testing but only sets the requirements and standards for other testers.

IEC 61215: Standards for crystalline silicon terrestrial PV modules

IEC 61215 is a key and widely embraced standard for testing residential solar panels. This standard indicates that the solar panel module has undergone rigorous stress tests, ensuring high-quality, optimal performance, and safety.

IEC 61215 solar standard requirements apply to monocrystalline and polycrystalline PV modules, the most common solar panel types.

Solar panels conforming to IEC 61215 standards undergo testing in the following areas:

  • Mechanical load test (wind and snow)
  • Electrical characteristics (wet leakage current, insulation resistance)
  • Climate tests (hot spots, UV exposure, humidity-freeze, damp heat, hail impact, outdoor exposure) and others

IEC 62716: Ammonia corrosion testing of photovoltaic (PV) modules ammonia corrosion

Do you live close to a farm or a place where livestock graze? If so, ask for IEC 62716 when choosing the panels with the right solar certification.

These solar panel tests determine a module’s resistance to ammonia (a poisonous gas primarily produced by the decay of plant and animal matter). Installing a solar panel system close to farms and livestock can be a concern, as ammonia corrosion can accelerate degradation in a panel. Then, it leads to lower overall electricity production over the lifetime of the system.

IEC 61730: Standard for PV module safety

Like with any electronic device, there is a potential for electrical shock in improperly constructed solar panels. This is where IEC 61730 comes into play. These solar regulations focus on the safety aspects of solar panels. It includes an evaluation of the module’s construction and testing requirements to assess the following:

  • Electrical safety
  • Mechanical safety
  • Thermal safety
  • Fire safety

Photovoltaic (PV) modules that pass the solar panel tests outlined in IEC 61730 prove a reduced risk of facing these types of hazards.

IEC 61701: Salt mist corrosion testing

The name gives you a hint. When planning to install solar panels on a beach house, it’s advisable to discover if the solar panels have successfully passed IEC 61701 module testing. Solar panels undergo a series of salt sprays in a controlled environment during testing.

Post-spraying, testers check modules for physical damage (corrosion or delamination) and evaluate their electrical output and overall performance. Solar panels that successfully pass IEC 61701 tests can be set up near roads with elevated winter salt levels.

IEC 60068-2-68: Blowing sand resistance testing

Some solar panels endure IEC 60068-2-68 testing to detect how well they hold up in sandy desert environments. Continuous exposure to abrasive sand can cause wear and result in physical or mechanical defects in a solar panel over time. If you are installing solar panels in an area prone to frequent sand or dust storms, consider selecting panels that have successfully passed these tests to enhance the durability of your system.

What Solar Certification & Testing Are Important in the Solar Industry

Underwriters Laboratories

This is another solar energy certification company based in the US. They conduct testing services and certifications for various products such as electrical appliances, industrial equipment, and plastic materials. For solar panel testing, they have two standards: UL 1703 and UL 61730. Let’s take a closer look.

UL 1703: Standard for flat-plate PV modules and panels

UL 1703 is an industry-standard solar panel module testing to check safety and performance indicators. Like IEC 61215 or 61703 tests, panels with this certification experience simulated climatic and aging tests. This solar certification means that panels have been proven safe regarding mechanical loads, fire, and electrical hazards.

You may notice that a solar panel spec sheet includes both UL 1703 and IEC 61730 under safety solar certifications; this is typical for any quality solar panel sold worldwide. UL 1703 is necessary for solar panels sold and installed in North America, while IEC 61730 is internationally recognized and widely applicable to the global solar market.

UL 61730: Photovoltaic module safety qualification

UL 61730, a newer inclusion to solar panel testing and certifications, contains the module testing procedures and standards of UL 1703 with IEC 61730. This particular solar certification means international approval regarding a panel module’s safety and performance.

Shortly, It will become common to see this certification — as opposed to both UL and IEC — because it is often the most cost-effective option for manufacturers. To complete solar panel testing, developers must provide multiple samples.

Completing UL 61730 module testing reduces the number of panel samples needed as well as testing time and costs for companies that are planning to sell in both North American and international markets.

Shaping a Brighter Future: The Power of Solar Certification

The solar panel industry is a relatively new field of work that faces a shortage of certified solar installers and professional electricians. You have a chance to earn a good spot under the sun if you decide to acquire industry-recognized solar certification.

Employers highly regard workers with proper solar panel technician training and relevant expertise to handle intricate design projects. Moreover, knowing various solar certifications of standard helps to select the most appropriate solar panel system for individual clients. Simply put, if you know the industry inside out, you are deemed to succeed.
