With the widespread application of solar power generation, the quality and reliability of photovoltaic modules have become the focus of the industry. In actual operation, photovoltaic modules may face various challenges from the natural environment, including the impact of hail. In order to ensure the reliability and durability of photovoltaic modules under hail weather conditions, the International Electrotechnical Commission (IEC) formulated the IEC 61215 standard, which requires a hail impact test. The Hail Impact Tester developed by Millennial Soalr plays an important role as a key equipment for evaluating the impact resistance of photovoltaic modules.

How Hail Impact Tester works

The Hail Impact Tester is a device specifically designed to simulate hail impacts. Its working principle is based on high-speed impact experiment technology, by launching hail-simulating samples to impact the photovoltaic module to be tested at certain speed and energy. The testing machine simulates the impact effects under different hail weather conditions by controlling parameters such as impact speed and impact energy. Hail Impact Tester plays an important quality control role in the photovoltaic module production process. Through the hail impact test, products with unqualified quality can be screened out to ensure the reliability and safety of factory products.

Steps for hail impact test of photovoltaic modules

1. Preparation

2. Install photovoltaic modules: Install the photovoltaic modules to be tested and ensure that their position and fixation method meet the test requirements.

3. Set test parameters: set parameters such as impact speed, angle and energy.

4. Run the experiment:

    a. Launch hail samples: Start the launch system and launch simulated hail samples.

b. Data collection: Record the data during the test through data collection equipment for subsequent analysis and evaluation.

5. Data analysis:

    a. Analysis of damage: Evaluate the damage of photovoltaic modules under hail impact, including appearance deformation, cracking, changes in electrical properties, etc.

    b. Result evaluation: Compare the test results with the IEC 61215 standard to evaluate the impact resistance and durability of the photovoltaic modules.

6. Conclusion and report

It should be noted that the hail impact test of photovoltaic modules should be conducted in a professional laboratory to ensure the safety and accuracy of the test process. At the same time, relevant safety operating procedures should be followed during the test to ensure the safety of personnel and equipment.

Hail Impact Tester

Hail Impact Tester is equipped with a variety of clamps, which can be adapted to photovoltaic modules of different structures; the speed of the ice puck can be monitored with a speedometer to ensure that the speed is accurate and intuitive; the ice puck is launched by compressed air, and the compressed air pressure is adjustable;

The ice ball launch point can be positioned by infrared rays to ensure accurate results; a waste ice ball treatment tank is designed to protect personnel safety.
