What length of warranty do my solar panels have?
This is a very important question as you need to know how long you can guarantee energy production from your investment.
Solar Power NZ only sell quality tested Tier 1 solar panels such as Canadian Solar and Jinko Solar. These panels both have a 10 year limited product warranty against defects. They also have a 25 year performance warranty that guarantees that the power output of a panel will be no less than 80% of the labeled output after 25 years.
The actual power output of the module shall be determined for verification using Standard Testing Conditions only. The actual power output measurement is either carried out by a Canadian Solar facility or by a Canadian Solar recognised third-party testing institute.
