Introduction
This document details the specifications and performance of the
Automated Solar Panel EL Tester—an essential module in any Solar
Panel Production Line—designed for precise EL Defect Testing.
Our system is engineered as an advanced EL Tester specifically
optimized for Large panel size EL Tester applications, delivering
thorough inspection of solar modules across all production stages.
This EL Tester effectively detects hidden cracks, fragments, faulty
soldering, grid breaks, and other efficiency-critical anomalies -
capabilities that make it indispensable for Electroluminescence
test sale implementations.This comprehensive detection process is
crucial for quality control in an Electroluminescence test sale
environment on a busy Solar Panel Production Line.

4. Dedicated Control Software
Industry-specific interface for intuitive operation
Photo-query functionality
Automatic barcode scanning and file naming; Chinese-language
interface; constant-current control; one-click scanning,
categorization, and saving; double-click to zoom images for
detailed EL Tester analysis
Flexible defect criteria: black spots, broken gridlines, fragments,
etc.; automatic defect-type statistics and text-report generation
for streamlined EL Defect Testing records
5. Wide Applicability
Suitable for monocrystalline and polycrystalline silicon modules in
all EL Defect Testing scenarios.
6. Defect Detection Principle
Electroluminescence (EL) brightness is proportional to
minority-carrier diffusion length. When voltage is applied, the
cell emits infrared light captured by the imager. Defective regions
with lower diffusion lengths emit less light, appearing darker,
thus pinpointing silicon wafer, diffusion, etching, printing,
sintering, or other process defects.
