Longi lr4 60hph 370m Solar Panels Review
There are quite a few 370w panels on the Australian market these days. However, they may be great panels too, but the Longi lr4 60hph 370m with its Hi-MO4 tech is a strong favourite.
The firm for many years, was a major supplier of silicon wafers to many other big brands, such as QCELLS. So, there is a strong following for the brand helped by some good marketing too.
The lr4 60hph 370m that Longi Panels Australia offers, has a very high efficiency rate of 20.3%. This is as good as many more costly panels, so the value can be seen.
These panels have half-cut solar cell technology, which works to lower power loss in the panel. This helps lower the heat in the panel too, so to reduce “hot spots”. These can cause lower output as well as panel failure.
longi 370w solar panels Review Mono Perc
The LONGi 370w mono PERC panel is the specific panel we have experience with, so we will focus on it. This panel has "PERC", which is in fact, just a fancy name for Passivated Emitter Rear Contact. So far we can report that this panel has met expectations, it’s a ‘game changer’ too. It's the first great, “standard size” mono 300 watt panel also at a price like similar poly panels.
So what is PERC? For most people, it’s hard to imagine what it's all about, but we’ll try anyway. What PERC does then is improve a panel’s ability to trap more light near the back surface, extracting more power. PERC was first developed in fact by the University of New South Wales in 1983. So there is something to crow about! Their approach also proved to be the best way to get high efficiency. As a result, the UNSW employed it to achieve multiple world records close to 25%.
The LONGi 370w panels come straight off the pallet very much so, looking the goods. A good, strong 40mm black frame also holding it all together. However, you would expect a top Tier 1 panel to be like this.
Why to choose Longi 370W?
The Longi 370W panels are a good choice for solar energy due to several compelling reasons. Firstly, these panels offer a high power output of 370 watts, making them an excellent option for both residential and commercial applications. Additionally, the Longi 370W panels feature high-efficiency monocrystalline silicon cells, which can convert sunlight into electricity with maximum efficiency.
Moreover, Longi 370W panels use innovative technology, such as PERC and half-cut cell technology, to improve performance and energy production even in low-light conditions. They are also designed to be durable and reliable, with a corrosion-resistant aluminum frame and tempered glass to withstand harsh environmental conditions.
Furthermore, Longi 370W panels come with a 12-year product warranty and a 25-year performance warranty, ensuring customers long-term protection and peace of mind. Overall, if you're seeking a top-performing, efficient, and reliable solar panel, the Longi 370W panels are an excellent choice for your solar energy needs.
Longi 415w Datasheet & Info
The Hi-MO5 415w is the latest from Longi Solar This panel ss rated at 415w, with 21.25% efficiency level.
The Longi 415w is a P Type silicon with half-cut solar cell and gallium doped to give very low LID. It's also supported by a 25-year performance guarantee. Longi won the 2021 Intersolar Award with their Hi-MO 5 for its advanced technology and innovation.
So How Did LONGi Solar Panels Start?
LONGi, founded in 2000, then at that time only making silicon ingots. Other panel makers used these to make their own panels, and were so good, the business took off. They grew fast, and now in fact make their own Longi Panels like the longi lr4 60hph 370m that we review. They make every item for their panels in house. LONGi has a grown fast, more so than any other maker in the world.
longi Going from Strength to Strength
We mentioned here a couple of years ago, that Longi Solar was the fastest growing solar maker. This was for 2016 and also 2017. The firm has kept the pace and now is at the top of the tree, with 20GW of panel capacity. That’s up from 5GW in 2017 – so its a massive increase. Bloomberg reports that Longi is the most bankable of all PV makers, and there’s some big fish in that pond. As such, they are also firmly within the “Silicon Module Super League”, group of manufacturers.
Longi solar panels review Australia
They are no longer the new kid on the Aussie block.
The turning point was in 2014. LONGi Green Energy Technology moved from just being a supplier of silicon for others and started selling their own panels. In fact, Lerri, a panel maker since 2007, became part of Longi Solar. They kept that brand alive until 2017 when they launched under their own name, Longi. Since then, they have been on the move very fast and are now in many markets around the world. With this growth in sales came the massive increase in capacity. Many firms experience problems with rapid growth, but Longi have been able to do it and not suffer.
LONGi Australia Warranty & Service
One of the most asked questions is whether a maker has an office here in Aussie. Yes, there is Longi Australia office in Sydney. And when we review Longi solar panels, we can confirm that at this time, we don’t know of any issues with any of their products, but if you still wish to phone Longi Australia you can get in touch on 02 8484 5806.
The panels have a 12 year product and also a twenty five year performance warranty.
LONGi Green Energy Technology - The World’s Largest Producer of Silicon Ingots
As part of the expansion, they took on a plant in Malaysia and also built one in India. Both have a 500MW capacity. In fact, the plant in Malaysia makes silicon ingots, and creates wafers from these for Longi Solar panels. All Longi panels are mono crystal, they do not make poly panels at all. They use the "Czochralski process" to create their silicon ingots, and are also now the world’s biggest maker of these. The ingots take form in very hot kilns at about 1420°C. As like many other solar PV panel makers, Longi invests very heavily into R&D. It does appear then, that they have been putting their money into the right places.
In 2021, LONGi Green Energy Technology total R&D investments was 1.614 billion yuan and set of new world records with its latest cell technologies.
