Solar Module IV Tester Technical Specification
Applicable Equipment: High precision solar module IV tester
1. Purpose of the Equipment
The High precision solar module IV tester is designed for the
automatic testing and result recording of the electrical
performance parameters of monocrystalline and polycrystalline solar
modules. This IV tester integrates a Solar simulator light source
and advanced data acquisition for precise IV curve measurement. It
is ideal for integration into a modern Solar panel production line,
providing reliable performance and seamless connection to
downstream processes.
2. Main Technical Indicators and Principles
