What is worse for a solar panel .  A bad angle or shading?

I have always wondered this and I think its shading.  As a bad angle still gets the sunlight.  Can someone please answer this?

    Shade is worse.   I don't even bother changing the vertical angle any more. It's set for winter optimum and summer has so much sun it seems to make little if any difference.  YMMV.  Being a little over paneled can also help with reducing the concern about exact angles. Panels are cheap enough to do that these days.

    Partial shading of a panel in bright sunlight is probably the worst because that is the circumstance that burns out the bypass diodes.
