Infrared inspection of PV (photovoltaic) modules is a non-invasive technique used to detect potential issues and anomalies in the panels. Here are some key points about infrared inspection:

1. Detection of Hot Spots: Infrared cameras can detect hot spots in PV modules, which can indicate issues such as cell damage, bypass diode failure, or shading.

2. Preventive Maintenance: Regular infrared inspections can help identify problems early, allowing for preventive maintenance to avoid more serious issues and downtime.

3. Efficiency Optimization: By identifying and resolving issues, infrared inspections can help optimize the efficiency and performance of PV systems, ensuring maximum energy production.

4. Safety: Infrared inspections are non-contact and non-destructive, making them safe for the panels and the inspectors.

5. Professional Inspection: It is recommended to have infrared inspections conducted by trained professionals who are experienced in analyzing infrared images and interpreting the results.

In summary, infrared inspection of PV modules is a valuable tool for identifying potential issues and ensuring the continued performance and efficiency of solar energy systems.
