Diode fault analysis device and method of solar module using solar simulator

摘要

The present invention is a solar simulator using a solar simulator that detects a faulty diode among a plurality of bypass diodes by irradiating different light intensities to a series structure consisting of three or four solar modules with an LED solar simulator to prevent accidents in advance. A diode failure analysis apparatus and method for an optical module, wherein a plurality of solar cells are connected in series and are divided into first to third zones, respectively, corresponding to the first to third zones of the solar module 1st to 3rd bypass diodes configured to be, and an LED solar simulator for selectively irradiating the same light source and different light sources to the first to third zones of the solar module according to set conditions, and the LED solar simulator An IV curve measuring unit measuring the IV curve of the first to third sections of the solar module through the light source irradiated through the It is characterized in that it is configured to include a determining unit for determining the faulty bypass diode among the first to third bypass diodes by calculating the IV curve of .
