This report focuses on On-site inspection methods that are helpful tools to identify the drivers for underperforming PV power plants.
Their particular strength is that tests can be performed without dismounting PV modules and shipping them to a test laboratory. It avoids transport risks and long PV systems down time.
On-site inspection allows a targeted failure analysis by selecting suitable test methods from:
- Electrical inspection techniques
- Imaging techniques
- Spectroscopic methods
