This was a great course! I looks at solar system monitoring all the time, but never often think of how panels function at the cell level. Very cool and interesting webinar. And Free!

This course is very informational even in the obvious aspects of damaging cells. This course definitely piqued my interest in furthering my education of solar cell testing.
