Certification bodies have to show that they fulfil the requirements for membership and will sign an agreement with the “Global Solar Certification Network” (GSCN) to participate. Signing this agreement means that the certification body will recognize certification done by the other participating certification bodies if they both recognize involved test labs and inspection bodies.

A GSCN manufacturer having already a certificate from a certification body member of GSCN, applies directly to the “new” certification body (also member of GSCN) who issues the certificate he wants next for his product(s).

The manufacturer shows the existing certificate and ask the test lab and inspection body which did the testing and inspection already to provide the “new” certification body with existing test and inspection reports. Test lab and inspection body shall be recognized by the “old” as well as the “new” certification body.

The “new” certification body will then tell the manufacturer if any additional testing/inspection will needed.

If no additional testing is required – or when such additional testing has completed – the manufacturer is granted the license to mark his product with the “new” certificate too.

The web site www.gscn.solar will show lists of certification bodies, test labs and inspection bodies participating in the GSCN – and also show which test labs and inspection bodies are recognized by which certification bodies.

Test labs and inspectors have show that they fulfil the requirements for membership and will sign an agreement with GSCN to participate. Test labs and inspectors need recognition by the certification bodies they work with.
