The PV Module Dust Resistance Chamber is a specialized equipment for evaluating the resistance, protection and long-term reliability of photovoltaic (PV) modules (e.g. solar panels) in dusty environments. Since PV modules are usually installed outdoors, such as in deserts, farmlands, industrial areas, etc., they are susceptible to dust, so it is crucial to ensure their long-term stability and high performance in dusty environments. Below are the detailed information about PV Module Dust Resistance Tester:
1. Functions and Uses
Simulation of dust environment: Through the dust generating device, dust is generated and circulated to simulate the dust environment that PV modules may encounter in actual use, such as sandstorms, industrial dust, agricultural dust and so on.
Dust Resistance Test: Evaluates the tolerance of the PV module in dusty environments to ensure that the photovoltaic conversion efficiency will not be affected by the accumulation of dust on the surface, and at the same time, tests the sealing performance to prevent dust from entering the interior and affecting the electrical performance of the module.
Comprehensive test: In addition to dust resistance, the performance of PV modules under different temperature, humidity and light conditions, as well as their mechanical and electrical properties, can also be tested.
2. Test standards and methods
IEC 61215: The International Electrotechnical Commission's design qualification and finalization standard for crystalline silicon PV modules for terrestrial use contains requirements for environmental testing.
IEC 61730: International Electrotechnical Commission standard on safety qualification of photovoltaic modules, including the requirements of environmental testing.
ASTM D1003: ASTM test method for haze and transmittance of transparent plastics, which can be used to evaluate the effect of dust on the transmittance of photovoltaic modules.
GB/T 2423.37: Chinese national standard that specifies the method of sand and dust test in the environmental test of electrical and electronic products.
ISO 12103-1: International Organization for Standardization (ISO) standard on Road Vehicles - Environmental Conditions and Tests, which specifies the method of sand and dust test.
3. Test procedure
1.
Initial test: under standard environmental conditions, the PV module is subjected to an initial test of appearance, basic function and photoelectric conversion efficiency.
2.
Sample placement: place the PV module in the test chamber to ensure that it is in normal working condition.
3.
Setting parameters: set the parameters such as dust concentration, airflow speed, temperature, humidity, light intensity, test time, etc. according to the test standards or customer requirements.
4.
Start test: Start the test chamber and begin the dust resistance test.
5.
Continuous monitoring: During the testing process, regularly monitor the performance and status of the PV module and record the relevant data.
6.
End of test: After the test, take out the samples, check the appearance, photoelectric conversion efficiency, sealing performance, etc., and evaluate the test results.
4. Assessment Criteria
Appearance inspection: Check whether there is dust accumulation on the surface of the PV module and whether there is dust entry in the sealing part.
Photoelectric conversion efficiency: Test the photoelectric conversion efficiency of the PV module under different dust concentrations and wind speeds, and evaluate its dust resistance performance.
Sealing test: Evaluate the sealing performance of the PV module to ensure that dust will not enter the interior and affect its electrical performance.
Electrical performance: Test whether the electrical performance of the PV module is affected, such as insulation resistance and contact resistance.
Transmittance test: Evaluate the effect of dust on the transmittance of the PV module to ensure that its photoelectric conversion efficiency is not affected.
5. Application Areas
Solar photovoltaic power plants: Test the tolerance and long-term reliability of PV modules in dusty environments such as deserts, agricultural fields, industrial areas, etc.
Building-integrated photovoltaic (BIPV): testing the tolerance and safety of building-integrated PV modules in dusty environments.
Portable Photovoltaic (PV): to test the endurance and reliability of portable PV devices in dusty environments.
6. Precautions
Safe operation: Operators should wear protective equipment, such as dust masks and protective glasses.
Equipment Maintenance: Regularly check and maintain the equipment to ensure its normal operation, especially the dust generating device and airflow control system.
Dust Recovery: Dust should be recovered in time after use to avoid environmental pollution.
Temperature and humidity control: Ensure the uniformity of temperature and humidity in the test chamber to avoid localized overheating or overhumidity.
Light simulation: If equipped with a light simulation system, ensure its stability and consistency to obtain accurate test results.
7. Advantages
Precise control: The ability to accurately control dust concentration, airflow rate, temperature, humidity and light conditions ensures the stability and consistency of the test environment.
Simulation of real environment: Through the composite test of dust and airflow, it simulates the dust conditions in the real environment and improves the realism of the test.
Versatility: Not only dust resistance test, but also simulation test of temperature, humidity, light and other environmental factors.
Programmable control: Users can set different test parameters as needed to improve the flexibility and adaptability of the test.
Comprehensive assessment: Comprehensively assess the tolerance and long-term reliability of PV modules in dusty environments to ensure their high performance and stability in practical applications.
