Are there any NZ Standards on solar panels?

All solar products should comply with AS/NZS 5033. Complying with the standard however is not always a guarantee for being a top quality product

Cheap solar panels and quality solar panels differ in:

1. Testing
2. Input materials
3. Warranty condition
4. Output and Efficiency
5. Corrosion protection on frame
6. Quality of Plugs and junction boxes
7. The quality of wafer and solder
8. UV resistance of the backing sheet
9. Chemical stability of seals and sealants
10. Weight and rigidity
