"Because the development time for new products has been considerably reduced, we no longer need to send prototypes to European test institutes, which has reduced our development costs."
- Paul McEntee, Kingspan Renewables UK
At the manufacturing stage, solar panels are inspected and tested to ensure the quality of the panels. Machine vision inspection identifies small manufacturing defects, and compliance testing ensures the solar panels conform to international quality standards and will survive in an outdoor environment for their expected long lifetimes. Solar validation and verification tests involve mechanical and electrical measurements such as stress, temperature, voltage, current, and moisture. Test applications include thermal cycle, accelerated life cycle, electrical connector, mechanical impact, fatigue, and nondestructive test techniques such as ultrasonic testing.
