ASTM G173 Solar Radiation Reference Testing for Certification
The ASTM G173 standard defines the procedure for characterizing and certifying materials used in photovoltaic (PV) systems to ensure they meet specified solar radiation exposure conditions. This service is critical for quality managers, compliance officers, R&D engineers, and procurement teams looking to verify that their materials will perform reliably under real-world solar exposure.
The ASTM G173 procedure involves exposing specimens to a controlled environment that simulates the spectral distribution of direct sunlight. The goal is to characterize the material's response over time under these specific conditions. This service ensures that PV system components are consistent with the reference spectrum provided in the standard, which helps manufacturers and installers meet regulatory requirements and improve product performance.
The testing process typically involves:
- Specimen preparation: Ensuring the material is cut to the specified dimensions for accurate testing.
- Spectral irradiance measurement: Using spectroradiometers to measure the spectral distribution of the reference solar radiation.
- Thermal and photovoltaic performance monitoring: Recording changes in electrical output as the specimen is exposed to varying solar conditions.
The data collected during this testing process provides critical insights into how materials will perform under real-world conditions, thus facilitating compliance with international standards such as ISO, ASTM, EN, IEC, and others. This ensures that the certified materials are reliable and can be used in high-performance PV systems.
| Parameter | Description |
|---|---|
| Test Specimen Size | The size of the specimen must be appropriate for the testing apparatus and should follow ASTM G173 guidelines. |
| Spectral Irradiance Range | The range of spectral irradiance to be simulated is specified in the standard, ensuring accurate representation of solar radiation. |
| Testing Duration | The duration can vary based on the application and desired exposure level, but it typically aligns with real-world conditions for durability testing. |
| Data Collection | Data is collected continuously during the test to monitor changes in performance over time. |
The ASTM G173 certification process ensures that materials used in PV systems are consistent with the reference spectrum defined by the standard. This helps manufacturers and installers meet regulatory requirements, improve product performance, and ensure long-term reliability of their products.
By following this rigorous testing procedure, laboratories can provide accurate and reliable data to support the development and certification of high-performance materials for photovoltaic systems.
