I heard that most panels have diode fitted.
Then I suppose it has to suit voltage that panel can produce plus margin of safety.

However panels often come with information that they can be in string up to say 700V or even 1000V

Does it mean that another diode is installed at the end of string?

I asked question because I have next to zero practical knowledge with solar systems installation.
