Instrument >> Instrument for Solar Cell >> Solar Cells and Modules online measurement system:PV-LIT
                

 

Product Introduction:

       The fully automatic PV-LIT testing system offers individual and serial testing options for solar cells and complete solar modules. The modular testing system allows easy integration into existing production lines and can be used in automated serial testing for quality assurance.

       PV-LIT inline guarantees 100 % quality inspection during the manufacturing process. Cycle times of less than 1 second and a continuous operation allows reliable tests in serial production.

 

Product Feature:

Use of either cooled or uncooled camera systems depending

On problem definition and customer requirements

Testing possible at very early stage of production

Cycle times of less than 1 second

Inspection for different defect types Various testing options

For different kinds of defects

Definition of user-defined test parameters (threshold,

Temerature level, number and size of defects)

Fully automated testing with classification

Flexible data interfaces (e.g. Ethernet, Profibus)

Long-term stability and continuous duty capability
