Description

The internal defects of photovoltaic cells seriously affect the service life and long-term power generation efficiency of photovoltaic panels, and even cause on-site fires, and defective photovoltaic cell modules will cause serious economic losses to the owner. In order to meet the needs of power station EL field testing, Suzhou Zisheng Technology Co. LTD has developed portable EL testing equipment, which is convenient to carry and easy to install, and can be tested under various complex field conditions to quickly diagnose EL defects of photovoltaic modules. It provides an important basis for the installation, operation and maintenance of photovoltaic power stations and the quality evaluation of power stations.
