Claim 4:
5. The power switch circuit according to claim 1, wherein the switch circuit comprises a second switch module and a third switch module;
a first terminal of the second switch module is connected with the solar photovoltaic panel, a second terminal of the second switch module is connected with the detection circuit, a third terminal of the second switch module is connected with a second terminal of the third switch module and the load respectively, wherein the second terminal of the second switch module is a control terminal, and the second terminal of the third switch module is a control terminal; a first terminal of the third switch module is connected with the detection circuit, a third terminal of the third switch module is used for grounding;
the detection circuit is configured to detect the electrical signal output by the solar photovoltaic panel, and in response to the power in the electrical signal greater than the preset threshold, the detection circuit outputs a first control signal to the second terminal of the second switch module to turn on the second switch module, the electrical signal flows into the second terminal of the third switch module while flowing into the load through the second switch module so as to turn on the third switch module, and a second control signal is fed back to the first terminal of the first switch module to turn off the first switch module so that the detection circuit stops working.
