What are The Solar Photovoltaic Panel Detection Methods?
Solar photovoltaic panel detection methods include visual inspection, electrical performance test, infrared thermal imaging detection, spectral detection, high-voltage insulation test, etc.
1. Visual inspection
Through manual visual inspection, check whether the surface of the photovoltaic panel has obvious damage, scratches, stains, etc. This method is simple and easy, but may overlook some minor flaws.
2. Electrical performance test
Use photovoltaic test equipment to test the electrical performance of photovoltaic panels, including current, voltage, power, efficiency and other indicators. This method can detect whether the performance of photovoltaic panels meets the standard, but requires specialized equipment and skills.
3. Infrared thermographic detection
The inspection of photovoltaic panels using infrared thermal imaging equipment can detect the temperature distribution on the surface of the photovoltaic panels, so as to detect possible defects. This method is more accurate, but requires specialized equipment and skills.
4. Spectral detection
The use of spectrometer to detect photovoltaic panels can detect the absorption spectrum and emission spectrum of photovoltaic panels, so as to judge the performance and quality of photovoltaic panels. This method requires specialized equipment and skills, but can provide more detailed information.
5. High voltage insulation test
Testing photovoltaic panels using a high-voltage insulation tester is able to detect the insulation performance of photovoltaic panels and thus find possible insulation defects. This method requires specialized equipment and skills, but provides more accurate information on insulation performance.
