Solar panel battery (internal, electrode)
This is the example of internal defect in panel and gluing condition of electrode, these factors affect solar power generation and degradation over time.
We introduce Non contact Air coupled Ultrasonic Testing system "NAUT21". This is the transmission method that places two air probes like sandwiches of solar panel.
You can find out the internal defect and delamination condition, gluing condition by NAUT.
