Verification method and device for vertical installation reliability of double-sided assembly

Abstract

The invention discloses a verification method and device for the vertical installation reliability of a double-sided assembly. The verification method comprises the steps that a verification device isarranged on the double-sided assembly, a thermocouple temperature measuring line, a photosensitive sensor, a light source and a strain gauge of the device are respectively arranged on the double-sided assembly, and then temperature change data, surface deformation data and wind pressure data on the double-sided assembly are respectively measured by utilizing the thermocouple temperature measuringline, the photosensitive sensor and the strain gauge and are transmitted to an industrial personal computer through a data collector; and an alternating-current distribution box and a photovoltaic inverter respectively transmit the generated energy data of a photovoltaic power supply generated by a photovoltaic module to the industrial personal computer. According to the verification method, thethermocouple temperature measuring line is adopted to directly collect real-time temperature changes of the surface of the assembly, the verification operation is simplified, the strain gauge, the photosensitive sensor, the photovoltaic inverter and the alternating-current distribution box are utilized to monitor wind pressure borne by the double-sided assembly outdoors, assembly surface deformation and generating capacity data in real time, and the accuracy of reliability verification is improved.

Description

technical field [0001] The invention relates to the technical field of installation and detection of photovoltaic modules, in particular to a method and device for verifying the reliability of vertical installation of double-sided modules. Background technique [0002] Bifacial modules are photovoltaic modules composed of crystalline silicon solar cells that receive light on both sides and generate electricity. Bifacial modules generate more electricity than conventional single-sided modules. The installation methods are diverse, and can be vertical or inclined, resulting in many new utilization methods, such as greenhouses, highway fences, sun rooms, curtain walls, etc. In the actual use of photovoltaic modules, reliability testing of the modules is required, but the current reliability testing technology and equipment are based on the conventional application direction of modules, and there are few tests for vertical installation methods and applications. [0003] In the ...
