Embodiment 1

[0037]The method for EL detection (also known as electroluminescence detection) of crystalline silicon photovoltaic modules in a photovoltaic power station is characterized in that it includes the following steps: assembling EL detection equipment, copying the serial number of the component to be tested, and powering on the component on the bracket after installation or Power on the delivered components, parameter setting steps, adjust the position of the infrared camera, retrieve the test components, take images, and record defects. Copying the serial number of the component to be tested includes the following steps: assigning a positioning number to the component, any component adopts the frame number in the field plus the positioning number, and the positioning number is from the upper row on the front of the frame component from left to right 1→n, and then by The lower row of the frame is numbered sequentially from right to left n+1→2n. The assembling of the EL detection e...

Abstract

The invention relates to an EL detection method for a crystalline silicon photovoltaic module of a photovoltaic power station. The EL detection method comprises the following steps: assembling EL detection equipment, electrifying a module on an installed bracket or electrifying a delivery module, adjusting the position of an infrared camera, calling a test module, shooting an image and recording defects. Due to the adoption of the EL detection method, whether abnormal phenomena such as subfissure, fragments, grid breakage and bright and dark sheets exist in the assembly can be detected.

Description

technical field [0001] The invention belongs to a crystalline silicon photovoltaic component of a photovoltaic power station, in particular to a detection method for a crystalline silicon photovoltaic component. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Photovoltaic modules need to be inspected on the surface. At present, there is no certain process standard and systematic inspection method for surface inspection. It is usually done by human eyes. During the inspection process, certain process parameters cannot be obtained, the quality of the product cannot be monitored, and the inspection efficiency is low. . In addition, as one of the core components of photovoltaic power plants, the quality of photovoltaic modules directly affects the power generation efficiency of the power plant. During the construction of photovo...
