This certification service is a voluntary scheme operated by JET.
The objectives of this scheme are to ascertain the reliability and the safety of Photovoltaic
(PV) modules and to promote wide application and usage of PV systems in the field
and thus to serve to end users.
Certificates are granted to each model of products after the successful completion
of applicable tests based on the IEC/IEC harmonized JIS standards and the factory
inspection of the quality management system at the manufacturing location.
