The solar panel tester that checks if light is coming out is really important when making solar panels for a couple of reasons: 1. Quality Assurance: The inspector looks at how the light comes out of the solar cells on the panel to see if there are any issues like defects or hotspots. This helps make sure the panel works properly and lasts a long time.
