Good morning fellow members,

 

If we add pv panels in series, then the voltage gets "added" en the total current stays the same.

When we add them in parallel, the current gets "added", and the voltage stays the same.

When does the bypass diode's current limit come into play? To me, it seems never, from the above, but I just want to sense check myself.

 

Regards,

Herman

Hi Herman. Bypass diode brings current when the cells that protects is in shadow and the other cells aren't.

... and hence the most current they ever conduct is the Isc of that individual string/panel, and therefore...

Thank you. I appreciate your responses.
