What’s so good about the Longi 370 watt?
There are quite a few 370-watt 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.
One of the most asked questions is whether a maker has an office here in Aussie. Yes, there is Longi Australia office in Sydney. At this time, we don’t know of any issues with any of their products.
The Longi LR4-60HPH-370M has a very high efficiency rate of 20.3%. This is as good as many more costly panels, so the value can be seen.
The Longi LR4-60HPH-370M has half-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.
So How Did LONGi 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 LR4-60HPH-370M that we offer. They make every item for their panels in house. LONGi has a grown fast, more so than any other maker in the world. Which you'll find out why also in our Longi Solar Panels Review. Also one thing not said yet is that they only make mono panels too.
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, no longer the new kid on the Aussie block.
The turning point was in 2014. Longi 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 370 watt - Solar Panel Review
The LONGi 370 watt mono PERC 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 370 Watt mono PERC comes 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.
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.
