PV Soldering Ribbon

Introduction

PV Soldering Ribbon acts as connecting between solar cells and collecting the current from solar cell string .The former is called as junction bar， the later is called as conflux bar . The electricity generating from solar module is conducted into junction box through them that are encapsulated in solar module. Our product is used in module factories, whose parameters are as same quality as foreign relative products, which had been proved by state-authority organization.
