Your inverter should come with a minimum of a five-year warranty, with quality suppliers offering extensions to 10 years free of charge or with minimal additional cost.
Solar panels or modules come with two types of warranties. The first is a performance warranty, which is a minimum guaranteed output from the panels, generally over a 25 year period. The second is a warranty on the manufacture of the module itself, which is for 10-12 years, covering items such as the glazing, framing and wiring.
Also very important is the workmanship or installation warranty – Solargain offers a five-year installation warranty.
Solargain chooses supply chain partners that are large, international, well established manufacturers who support their products locally in Australia with their own staff and offices.
The products that we recommend are not only used for many other commercial systems, but also for large international solar projects, including both rooftop and utility scale projects.
This is important from a quality point of view and also from a financial stability point of view. The warranties provided for the core products extend over many years, which means we need renowned manufacturers who are able to stand behind their warranty obligations for the long term.
Solargain does not supply panels that are not independently assessed by peer reviewed organisations such as Bloomberg Energy Finance US and therefore appearing on their Tier 1 solar panel manufacturer list. Such accolades recognise the manufacturer’s commitment to quality manufacturing processes, independent testing and certification, longevity and stability in the market, and after-sales service.
We also assess the manufacturer’s global reputation – proved track record in markets that they have been operating in for longer than in Australia.
