The invention discloses a photovoltaic module detection method and device and a photovoltaic module detection circuit. The method comprises the following steps: in a detection period of a photovoltaic module, controlling an input voltage input to an output power adjusting circuit through a voltage control module, so an input end and an output end of the output power adjusting circuit are in short circuit, and the photovoltaic module is directly connected with a detector; enabling the output end of the photovoltaic assembly to be connected with the input end of the voltage control module and the input end of the output power adjusting circuit, enabling the output end of the voltage control module to be connected with the input end of the output power adjusting circuit, and enabling the output end of the output power adjusting circuit to be connected with the input end of the detector. According to the invention, the technical problem that the current-voltage characteristic detection of the photovoltaic module is affected due to the fact that the output power adjusting circuit cannot be started within a short illumination time and the photovoltaic module cannot be directly connected to the detector is solved.
Description
technical field [0001] The present invention relates to the technical field of photovoltaic module detection, in particular to a photovoltaic module detection method and device, and a photovoltaic module detection circuit. Background technique [0002] Photovoltaic modules need to be tested for current-voltage characteristics before leaving the factory. During the test, the photovoltaic module has been in the dark room without power output; only when the photovoltaic module receives high-brightness light for a few milliseconds (the light time can be adjusted within the range of 2 to 10 milliseconds), it will output power. While the photovoltaic module is receiving light, the detector connected to the output terminal of the photovoltaic module starts to draw current step by step from small to large, and at the same time record the corresponding voltage values at different load currents, thus completing the test of the current-voltage characteristics. However, when a smart ...
