Bypass Diodes in Solar Panels
Bypass diodes in solar panels are connected in "parallel" with a photovoltaic cell or panel to shunt the current around it, whereas blocking diodes are connected in "series" with the PV panels to prevent current flowing back into them.
Are blocking diodes really needed for solar panels in …
The rationale behind this seems to be that one of the panels does not drive a current through the other panel in forward direction (hence the name "blocking diode", as opposed to the bypass diodes that are part of modern …
