LONGi produce monocrystalline/monosilicon panels. Monosilicon panels are more efficient than polysilicon panels which are commonly seen on the market.

Polysilicon panels are easier to make but are made up of multiple crystals of silicon. This reduces the efficiency of the panels.

Monosilicon on the other hand, is harder to make. They’re also more expensive. But, the benefit is one large crystal of silicon instead of many smaller ones. This means the panels are more efficient with up to 22.5% efficiency.

LONGi’s warranty is solid. Along with a 10 year parts warranty, LONGi promise their panels will still produce 83.1% of their original output in 25 years. This is 3% more than most panels in this price range.
If you need to make a warranty claim, call the team that installed the panels for you. They will need to honour the warranty.
If you’ve had LONGi panels installed by a company that is no longer in business, simply call 02 8484 5806.

Conclusion:

LONGi is a great company with an amazing track record. The panels they create rival the best on the market. Their warranty is strong and the service team can easily be contacted.

With the extra features to help with efficiency in shaded areas and an improved performance warranty, these are panels we feel comfortable installing on customers roofs and our own.
