PHOTOVOLTAIC SOLAR ASSEMBLY AND SWITCHING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/165010

Kind Code:

A1

Abstract:

A photovoltaic solar assembly and a switching method therefor. The photovoltaic solar assembly comprises an execution junction box, a single master control junction box, and a plurality of solar cell strings that are connected in series; the execution junction box comprises a corresponding bypass diode; the master control junction box comprises a corresponding bypass diode and a control assembly, and the control assembly is merely arranged in the master control junction box; the solar cell strings are connected in series with each other by means of the corresponding bypass diode of the execution junction box or the corresponding bypass diode of the master control junction box; and the control assembly is used for controlling connection and disconnection between the solar cell strings and a main power circuit. According to the present invention, the control assembly is integrated into a single junction box, so that the size of the execution junction box is reduced; and only the master control junction box having a large size is remained, wiring is separately performed on the master control junction box, and the master control junction box is placed in a region where the solar cell strings are not shielded, so that the projection area of each junction box on the light facing surface of a solar cell is also reduced, and the photoelectric conversion rate of a photovoltaic assembly is improved.
