So I did a 7K solar system in 2009. A year or two later I was reading about a new converter that removed the penalty for partially obstructed panels. In other words, if one of the 4 panels in a row is in shade, you still get some power generated.
Has anyone done a retrofit on an existing system to add one of these or does it not make any sense? If you have to replace the inverter, probably is not worth it.
