Frequently Asked Questions

Answers to questions we get asked alot:


Q: What does Solar Panel Supplies do to ensure materials really are TUV compliant?

Compliance to TUV Bill of materials is part of contract terms.

  • For each shipment we inspect production with an Australian or European representative of our company.
  • The inspector is present at the start of manufacture to confirm the Bill of materials and follow the production from start to finish.
  • On nearly every inspection we have found and corrected variations to the bill of materials.

This is not, of course, a cheap exercise but we feel it is worthwhile to ensure that we are delivering what we promise and to make sure the system you invest in will last you 25 years.

Q: Why Panels should be built to the bill of materials in the test certificate?

The CEC accredited panels is based on modules having test certificates from test bodies such as TUV which are tested to standards such as EN61215.

The tests are comprehensive and a good guide to the quality of the product. They also form the basis of performance claims.

However, if the materials used in the quality certificate are changed it becomes invalid. The performance claims and the CEC accreditation are equally invalid.

Changing materials has far reaching effects on;

  • Module performance claims
  • Expected long term life and performance expectations
  • Safety and protection from failure. Moisture ingress in to junction boxes has been known to have been the cause of electrical fires which have caused substantial damage and loss to installers.

As a director you have a responsibility to show “Due diligence” to ensure the safety of your product and we believe the only true way to do this is through independent checking to ensure compliance to the bill of materials listed in the quality certificate.
