PV module testing and certification

The purpose of these tests is to assess the electrical properties of the module and demonstrate, as feasibly as possible within reasonable cost and time constraints, that the module can endure extended outdoor exposure. These tests are designed for all terrestrial flat plate module materials, including crystalline silicon and thin-film modules.

This section of IEC 61730 outlines the essential construction requirements for photovoltaic (PV) modules to ensure safe electrical and mechanical operation. It addresses specific areas to evaluate the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. IEC 61730-1 covers construction requirements, while IEC 61730-2 details testing requirements. Modules with modified construction are qualified according to IEC TS 62915. This standard applies to all terrestrial flat plate module materials, including crystalline silicon and thin-film modules.

Photovoltaic (PV) modules are electrical devices typically designed for continuous outdoor use throughout their lifespan. However, highly corrosive wet environments, such as marine areas or locations near oceans and large saltwater bodies, can eventually degrade some components of PV modules. This includes corrosion of metallic parts and deterioration of non-metallic materials, such as protective coatings and plastics, due to salt assimilation. Such degradation can impair the modules' functionality. Temporary corrosive environments can also occur in areas where salt is used during winter to melt ice on roads and streets.

Tests are available to assess the resistance of various PV modules to corrosion from salt mist containing chloride compounds (e.g., NaCl, MgCl2). These tests can be applied to both flat plate and concentrator PV modules and assemblies.

Photovoltaic (PV) modules are electrical devices designed for continuous outdoor exposure throughout their lifespan. Highly corrosive wet environments, such as those found in agricultural stables, can eventually degrade some components of PV modules. This degradation includes corrosion of metallic parts and deterioration of non-metallic materials, such as protective coatings and plastics, due to ammonia assimilation. Such damage can impair their functionality and safe operation.

This standard outlines test sequences that are useful for determining the resistance of PV modules to ammonia (NH3).

This test measures how well a solar panel works under different light levels (irradiance) and temperatures. It helps determine how much power (in watts) the panel can produce in various real-world conditions. The goal is to create a standard way to test and rate the performance of solar panels.

This test checks how well solar panels handle stress from high voltage in hot and humid environments. It looks for a specific type of power loss, called potential-induced degradation (PID), and uses special methods to predict how much this might happen in real-life outdoor conditions.

This test simulates the physical stresses a solar panel experiences, like wind, snow, or handling during installation. By applying alternating forces to the panel, it checks if parts like solar cells, electrical connections, or seals might break or fail over time.

This test evaluates the materials used in solar panels, such as adhesives and encapsulants. It measures things like strength, flexibility, and how well the materials conduct electricity or handle heat. The results help manufacturers ensure quality and reliability during production and over the module's lifespan.

This test is for solar panels used in very hot environments. It checks their performance and durability when exposed to temperatures higher than typical standards. Two levels of high-temperature conditions are tested, depending on how hot the panels are expected to get during their use.

This test goes beyond the basic certification tests to see how solar panels hold up over a longer time. It evaluates the materials and designs used to make the panels and checks for potential issues that might show up after years of operation. It’s especially useful for comparing different panel designs or materials.

This test is designed to assess the effect of light induced degradation at elevated temperatures (LETID) by application of electrical current at higher temperatures.
