Apparently, panels use to have blocking diodes installed, but not anymore?

i think only low power trickle panels ever had reverse diodes

solar makes use of "bypass diodes" for shaded cells or panels
and "blocking diodes" in special applications

there is no reason for blocking diodes on a panel that is to high voltage to be directly connected to a battery bank and has to use a controller
the controller performs that function
