It can be difficult when purchasing a PV module to understand what makes a quality product. While the modules on the Clean Energy Council Approved Products List meet the relevant Australian and International Standards, this is only a minimum requirement.
To assist purchasers in identifying quality products, the Clean Energy Council’s list of approved PV modules now highlights products that meet a range of higher standards through Enhanced Listings.
An Enhanced Listing means that the manufacturer has undertaken to use only those materials that meet both the base standards and the requirements of the additional standards.
Enhanced Listings give installers and consumers the critical information they need to select modules of the highest possible quality and that are appropriate to their installation environment.
The following provides a description of the Enhanced Listings currently included in the Clean Energy Council's Approved List of PV modules.
Rigorous surveillance and in-line production testing of production modules to existing standards is provided by the VDE Quality Tested program.
This certification program has been developed to provide assurance of increased confidence in the quality of modules. Along with quarterly laboratory testing of a sample of production modules.
This standard is important if you are installing in a coast location, particularly within 500m of the sea to ensure the modules will not degrade prematurely.
This is important in the vicinity of intensive livestock production such as chicken, pig and cattle sheds. The animals give rise to ammonia which can degrade some panels.
This technical standard provides test methods for resistance to potential-induced degradation (PID). PID resistance is an important requirement particularly for larger systems where long-term output must be assured.
Installations in hot humid environments are particularly prone, and the problem is exacerbated with higher system voltages. As a technical standard, there are two alternative test methods and no pass/fail criteria. CEC currently allows certification to Method A with <3% degradation.
Materials will be verified as part of the Clean Energy Council's test program, and non-complying products will be considered to be in breach of the listing Terms and Conditions.
Claims on datasheets of higher standards that are not granted an Enhanced Listing must be marked “optional” or “on request” if the Clean Energy Council has sighted evidence of testing. If no suitable evidence can be supplied, the claim is required to be removed.
When applying to have a PV module listed with an Enhanced Listing, please use the Enhanced Listing checklist to ensure that you include all the required documentation.
