Warranties On Your Photovoltaic System

Warranties On Your Photovoltaic System

As a PV system is made up of several components usually manufactured by different companies, each component has its own warranty.Auxin has a 5 yr panel warranty


Product Workmanship
Most panel manufacturers offer a 5 year product workmanship warranty.

Power Output
Most panel manufacturers offer a 80% 25 year power output warranty and a 90% 10 year power output warranty. This means that your system is warranted to produce 90% of its rateable output for 10 years after installation and 80% of its rateable output for the next 15 years.

This warranty is only of use if the manufacturer is still around in 25 years time to honour it.

Inverter Sunny Boy inverter 5yr warranty plus option extend

Most inverters come with a 5 or 6 year warranty and good quality inverter manufacturers provide an option to extend the warranty for a further 5 or 10 years.

This warranty extension is built into the price of some of inverters making the initial purchase price more expensive but making the warranty look better even though there is no real difference in the inverter offered.


Your retailer provides this guarantee, even if the system is installed by a subcontractor. The guarantees retailers offer vary greatly from 1 - 5 years.

The installation guarantee covers inappropriate system design as well as faults with the installation. 

Air and Water provides a 5 year installation guarantee.

Service Agents

If there is a problem with your system you need to understand who will come to rectify it given that nearly all manufacturers are outside of Australia. Air and Water's service agents for their Auxin system is Solarflo. Solarflo is located in Perth.
