Abstract
A junction box electronically connected to a solar panel and connected to a plurality of solar cell strings connected in series includes a first bypass diode string and at least one second bypass diode. The first bypass diode string includes a plurality of first bypass diodes forwardly connected in series, and each of the plurality of first bypass diodes is connected to a corresponding one of the plurality of solar cell strings in parallel. The at least one second bypass diode connected to at least two neighboring solar cell strings in parallel, turns on to bypass the at least two neighboring solar cell strings upon the condition that the at least two neighboring solar cell strings are abnormal simultaneously.
