ie a 50% illuminated panel when optimally LOADED will make ABOUT 50% output.
But, as V_50%_optimal <>Vmp , when connected to a stiff bus at Vmp some
reduction in power is expected.

​Somewhat like std understanding and somewhat like my prior - although
panels draw far less back current than may be expected in most cases. ​
