Longi Solar was formed in 2000 in Xi’an Xinmeng, China, and is named after Jiang Longji, the former president of Lauhou University. They are one of the world’s largest solar manufacturers, with $8 billion in revenue and over 60,000 people worldwide. This places them in the top tier of solar panel manufacturers.
Longi’s primary product is monosilicon solar wafers, which are widely used in solar panels. Their 2017 expansion into Australia saw them capture the majority of the Australian solar market, making them the #1 solar panel for Australians in Q1 of 2021, with a 25% total market share.
Longi is the only solar panel manufacturer to be named AAA rated in the PV ModuleTech bankability Ratings in Q3 2020, and it also has headquarters in Sydney, Australia, led by Stephen Zhang.
How Good Are Longi Solar Panels?
Longi provides a superb solar panel that is both reliable and cost effective, and suits most homes in Australia, with one of the greatest solar PV module efficiency at 21.3 percent (Hi-module 5).
While their primary production focus has been on monosilicon wafers since 2000, this has allowed them to develop greater efficiency solar panels than their competitors at a comparable price. Longi Solar Panels come with a 12 year product guarantee and a 30 year performance warranty.
Longi outperforms other solar panels in terms of degradation rate, which is the pace at which the solar panel’s efficiency in converting light into electricity degrades over time.
Over the duration of the solar system, their average degration rate is 0.55 percent. This is the purpose of the performance warranty guarantee. The traditional degradation rate of other solar panels is 0.7 percent, which means the Hi-M03, Hi-M04, and Hi-M05 will produce 1.85 percent more after 10 years and 3.35 percent more after 20 years.
Different Types Of Longi Panels
Most solar panel manufacturers offer a wide range of solar panel modules with different kw per panel. Longi is no exception.
The list in Australia as follows..
- LONGi LR4-72HPH (420W – 455W) Mono
- LONGi LR4-72HBD (415W – 455W) Bifacial
- LONGi LR4-60HPH (350W – 375W) Mono
- LONGi LR4-60HBD (345W – 375W) Mono
- LONGi LR4-60HPB (340W – 365W) Mono, All Black
Longi Solar Panel Cost
Being a mid tier high quality solar panel longi is quite competetive when it comes to its pricing. When compared to other solar panels such as canadian solar Longi generally comes out ahead.
Below are the costs of both longi and canadian solar. This includes full installation with a Approved Solar Retailer and includes the solar rebates.

Why Longi Solar Only Makes MonoSilicon Solar panels
When it comes to the manufacture of solar cells, there are two basic types: monosilicon and polysilicon.
Polysilicon solar cells are relatively simple to manufacture, however they yield less energy. This is due to the fact that the solar cell is composed of numerous silicon crystals, which impacts total efficiency.
Monosilicon cells are produced from a single big crystal created by the czochralsji technique. This technique is more difficult and costly, but it results in higher solar cell efficiency.
Where Are Longi Solar Panels Made?
Longi manufactures solar panels in China, Vietnam, India, and Malaysia. Longi produced around 24GW of solar panels in 2020, thanks to its ever-expanding output.
Its solar wafer production capacity is 85GW, and future projects at its Kinchan and Tenchong facilities will increase that.
Longi Panels Warranty Procedure
Long has an Australian presence in Sydney, which makes it considerably easier to file warranty claims. This is critical for previously installed longi solar systems installed by a solar firm that is no longer in business to honour warranty claims.
Longi, the manufacturer, is responsible for that warranty. You may reach them at 02 8484 5806.
Conclusion
Longi Solar Panels are an excellent, dependable mid-tier solution for homes. Their Tier 1 position indicates that they are well-funded and will most likely be around for the long haul. So, if your solar installer goes out of business, you can be certain that you will always be able to access your warranties.
