Abstract

A device for detecting the damage and aging of a battery plate of a solar photovoltaic battery module matrix is characterized in that a universal coupling base is fixedly connected with the top end of a tripod; a laser light source/LED light source is fixedly connected with a universal head on the top end of a universal coupling; and both poles of a large solar photovoltaic battery module matrix are connected with both poles of a digital voltmeter. The detection method comprises the following steps: aligning the laser light source/LED light source to one solar battery plate at night; measuring the output voltage of the large solar photovoltaic battery module matrix at the moment; comparing the measurement value with the factory preset standard open voltage of the solar battery plate; determining that the solar battery plate is damaged if the output voltage is zero, and recording the position; determining that the solar battery plate has no damages and aging if the output voltage is equal to or larger than 95% of the factory preset standard open voltage of the solar battery plate, determining that the solar battery plate is aged to different degrees if the output voltage is smaller than 95% of the factory preset standard open voltage of the solar battery plate; and detecting the battery plates one by one to obtain the final result. The device has a simple structure and a correct detection result, and is convenient in operation.

Description

technical field [0001] The invention relates to a detection device and detection method for cell damage and aging in a matrix of large-scale solar photovoltaic cell components, and belongs to the technical field of damage measurement of solar photovoltaic cell panels. Background technique [0002] Human society is currently in the process of transitioning from a high-carbon economy to a low-carbon economy. Energy is the primary prerequisite for the development of modern human society, and solar energy is inexhaustible and inexhaustible. It is the first choice for new renewable energy without any pollution to the environment. Making full use of solar energy is an effective way to solve future energy shortages, protect the environment, reduce the release of greenhouse gases, and prevent global warming. The efficient use of solar energy will play an important role in the transformation process. From 2000 to 2008, the average annual compound growth rate of global solar cell pr...
