Electroluminescence and visual inspection system for PV module
EL & VI Tester
An EL & VI tester is an electroluminescence and visual inspection system for PV modules. The tester can detect and shoot a range of defects and automatically name and save the images. Adopting Sony camera chip and the 55-inch 4K monitor, the testing equipment is an ideal machine for increasing testing efficiency and improving testing processes for solar panel manufacturers and quality assurance departments.
