Credibility to the certified products will increase, as those products bearing JETPVm certification mark prove compliance with relevant international standards through a series of tests carried out by JET as the third party testing body.

The mark is put on those products which have passed various performance and safety tests (conformity tests) based on the relevant international standards and have been manufactured under the strict quality control.

Those products currently covered by the JET PVm Certification Scheme are crystalline silicon and thin-film PV modules which are designed and intended to be installed in terrestrial PV power generation systems other than concentrator types and are manufactured for sales purpose.

Certification is granted to each model of modules after the successful completion of a set of conformity tests in accordance with the requirements of relevant international standards and the management of the initial factory inspection of the manufacturing and quality control system.
The certification granted is valid for the period of 5 years.
Once registered, the factories are then subjected to the regular factory inspection once every year in order to retain the certification during the 5 year period.

Clients are required to fill out the application form prepared by JET. JET accepts the application after confirming the entries of forms and test samples required for the test.

Conformity tests are carried out on the samples of each model submitted which are considered to represent the mass production.
For similar modules which have similar specifications to those previously certified JET may carry out only those tests that are necessary to evaluate the acceptability depending upon the differences between the similar models and those already certified.

Factory inspections are consisting of the Initial factory inspection (carried out simultaneously with the conformity tests) and the regular factory inspections.
The initial factory inspection is carried out to ensure the manufacturing system is suitable to keep manufacturing the products to be certified in a stable.
The regular factory inspection is performed for the purpose of follow up once every year.

Fees required for certification are expected to basically consist of test fee, factory inspection fee, registration fee and certification mark fee.

When a client (certification holder) wants to withdraw the certification, an application is required to be submitted to JET using the “Notice for cancellation” form.
Certification may be cancelled or revoked even during the valid period of the certification, if the requirements set forth in the rules for JETPVm certification are neglected.
