What is the difference between bypass diode and blocking diode?
I think I am just confused with this diode issue. I would appreciate if somebody can just clarify the topic about bypass diodes and blocking diodes. I am not an electrician or a designer, but I'd like to understand. Thank you.

Diodes in a module perform two different functions- depending on where they are installed.
Diodes use their internal field to allow electric current to flow one way in a circuit and prevent it from flowing back.
Bypass diodes are installed in parallel with modules, they and they perform a bypass function allowing current to pass around a shaded area of a module.
Blocking diodes are installed in series with a string of modules, and they perform a blocking function, preventing backflow down the module string.
