JET certifications

What are JET solar PV certifications?

The Japan Electrical Safety & Environment Technology Laboratories (JET) assume the testing and certification services for assessing the reliability and safety of PV modules produced in or exported to Japan. Manufacturers, trading companies or importes may requst certification of their PV modules to ascertain its compliance with Japanese laws. The solar testing services of JET comprise both crystalline silicon and thin-film PV modules which are designed for application in terrestrial PV power generation systems. During the quality assessment process, JET tests both the products as well as it inspects the factory to analyze its quality assurance system. If passed, the manufacturer receives official JET certification for each tested model. The certifications are then valid for 3 years and registered companies are regularly inspected by JET.
