The photovoltaic module mechanical load testing machine is used to verify the ability of the module to withstand static and dynamic loads such as wind pressure, snow pressure, or icing at different installation angles. Widely used for testing the compressive strength of photovoltaic modules, dynamic holding pressure technology is used to simulate load tests to understand the compressive capacity of modules under wind pressure, snow pressure, static pressure, and ice load.

The photovoltaic module mechanical load testing machine is suitable for the following standards:High precision simulation testing equipment developed and produced for testing standards such as IEC62782, IEEE1262, IEC61215, UL1703, etc. Static mechanical load testing of photovoltaic modules is a very important test in international standards for verifying the ability of modules to withstand static loads.

Nowadays, market experience suggests that various testing methods are used to verify the uniform mechanical load bearing capacity of photovoltaic modules in a horizontal state. However, in practical outdoor applicationsdressdresstimeComponents all have a certain inclination angle and require a specific testing method to measureitsResistance to load.

IEC 62938 is the response of the IEC Photovoltaic Working Group to this market demand and was recently released. This new standard provides a method for measuring the load-bearing capacity of frame type photovoltaic modules under non-uniform snow loads.

Static mechanical load is usually applied by first applying pressure of 2400Pa on the front of the component for one hour, then flipping the component over and applying pressure of 2400Pa for another hour. This process is repeated three times, and the front pressure of the component increases to 5400Pa in the last cycle. After the experiment is completed, test the appearance, IV and wet leakage performance of the components.

The dynamic mechanical load is usually applied to the front of the component with a positive and negative pressure cycle of 1000Pa, 3 cycles per minute, for a total of 1000 times.

In order to simulate the pressure on both sides of the component to the maximum extent and ensure the uniformity of pressure, the most uniform way is to use liquid pressure. Considering the safety of on-site use and cost control, liquid water is the most cost-effective choice. However, due to the density of water1000kg/m3, currently the area of large-sized photovoltaic modules is about 2.6m (which may be even larger), and the maximum pressure applied is generally 5400pa. Simply using water to apply pressure, with a height exceeding 50cm, is very unstable and difficult to operate.
The three standards IEC 61215-1, IEC 61215-1-1, and IEC 61215-2 play an extremely important role in the field of photovoltaic testing and certification
