Abstract

This invention discloses a photovoltaic module. The photovoltaic module includes a first battery string connected to a first end busbar and a first middle busbar; a second battery string connected to the first middle busbar and a second end busbar; a third end busbar extending in the direction of the first end busbar; a second middle busbar extending in the direction of the first middle busbar; a third battery string connected to the third end busbar and the second middle busbar; and a fourth battery string connected to the second middle busbar and the second end busbar. The third end busbar and the second end busbar extend beyond the backplane and are connected via a second cable. The second middle busbar extends beyond the backplane as the first polarity output terminal of the photovoltaic module, and the first middle busbar extends beyond the backplane as the second polarity output terminal of the photovoltaic module, with the first and second polarities being opposite. This embodiment can improve the reliability of the photovoltaic module and increase the light-receiving area.
