What Is Pv Evolution Labs Top Performer
PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panels performance.
LONGi are named as a top performer in all 6 tests in the last report.
Where Are Longi Solar Panels Made
The majority of the manufacturing takes place in China, and it is later shipped around the world. Longi, on the other hand, has manufacturing facilities in India, Vietnam, and Malaysia. This is understandable because labor is much cheaper in these countries. And this is a significant reason why longi solar panels are so inexpensive. This does not imply that they sacrifice quality. Based on their history, customer reviews, and overall dedication to their craft, it is clear that they are committed to delivering high-quality green energy solutions to the general public.
They have offices in many countries, including longi solar panels Australia, Japan, the US, and South Korea, and so on. Their headquarters are in Sydney, Australia.
What Mounting Is Suitable For Longi Solar Panels
When attaching LONGi solar panels, the installation location must be taken into account, and in the case of roof installation, the roofing material.
First, the most convenient and correct place needs to be chosen for the installation of solar panels. If the ground type of installation suits you, then there are two types of ground mounting: standard ground mount and pole mount. Standard ground mount uses a metal frame that is screwed into the ground to hold solar modules. Pole mounting is considered the most reliable type of mounting and can hold multiple panels.
If you plan to use the roof to place the panels, then you should think not only about the method of attachment but also about the roofing material. Most roofing materials are suitable for LONGi solar panels with the metal roofs being the best choice and slate roofs being not ideal.

Longi Solar Have Certainly Been Moving Ahead In Leaps And Bounds Over The Last Few Years
After previously being the worlds largest Mono silicon module producer opening 20 years ago in 2000.
Longi have taken technology with their own brands to new heights and are quickly becoming known as one of the best solar panel manufacturers in the world.
In the last couple of years they have.
- Broken the world record for cell efficiency. 3 times.
- Taken the number one spot in the world for Bloomberg Tier one list.
- Have developed a significant reputation for providing well priced but highly efficient solar panels.
- Scored very highly in independent DNV testing.
- Passed MAST testing for backsheet durability.
The new Longi Hi-Mo X seems to be no exception to this.
It boasts a huge 350 watts of power in the size of a normal solar panel. This brings it up in line with the most expensive brands such as LG and Sunpower for high efficiency at around half the cost of their competing power class brands.
The Solar panel itself also has a sleek design that is aesthetically pleasing. Its mono Tile all-black design with black frames is definitely of the best looking solar panels on the market today.
Longi have also been given accreditation with the CEC MAST program
This is given to solar panels that have passed additional testing such as DNV PVEL, James cook university Cyclone testing and a host of durability tests.
Very few panels boast this accolade.
Longi 370w Solar Panels Review Mono Perc
The LONGi 370w mono PERC panels 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, its 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, its hard to imagine what it’s all about, but well try anyway. What PERC does then is improve a panels 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 panel 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.

Why Is It So Important To Use The Best Solar Panel Brands
A recurring point we make on SolarReviewsis that solar panels last a long, long time 25-30 years to be exact. This makes it importantto buy solar panels with the following qualities:
They are the least likely to fail.
- The manufacturer will honor their warranty if there is a fault.
- Installed by a local solar company who will still be in business if there is a fault and will do thetesting necessary to lodge a successful warranty claim with the manufacturer.
This third point is very important in practical terms, and a good reason why it is not always wise to buy solar from the cheapest company.
How Long Is The Warranty On The Longi Solar Panels
All LONGi solar panels come with a 10-year product warranty on materials and processing and a 25-year extra linear power output warranty. If you are in need to contact LONGi solar, the USA representative office is always at your service.
To see the warranty information, please refer to the datasheet available on product pages.

What About When You Compare Longi & Jinko To High End Panels Like Lg Or Sunpower
We also offer many high end products like LG, Sunpower and Hanwha Qcell.
If you consider your Average 6.6kw system in Melbourne, Brisbane or Adelaide, Sunpower or LG panels can cost $2000 to $4000 more than Longi or Jinko solar panels. For many Australians this may not be within their budget even after the solar rebates.
Even for those who have the budget, the ROI will not be fast enough from these solar panels.
Also Longi and Jinko are now producing much more efficient solar panels. As new technology develops, they are catching the wind and improving their solar panels. Here is a list of the most efficient solar panels in 2020.
For example we have many customers looking for a 2 year turnaround on ROI as they might move house after 5 years so why worry about LG or Sunpowers 25 year warranty??
Longi or Jinko can offer extremely fast ROI without compromising too much on quality. This is similiar to Canadian solar vs Jinko as well

What Cell Types Of Longi Solar Panels Are The Best
Monocrystalline solar cells are considered the best type of solar cells. They are made from a single silicon crystal and thus have much higher efficiency and sleeker aesthetics compared to polycrystalline cells. It is known that monocrystalline solar panels are the most efficient panels on the solar market with an efficiency of more than 22%. Thanks to their efficiency, monocrystalline panels are the most space-efficient panels and take up less space than any other solar panels. Also, monocrystalline panels are more durable and have a longer lifespan than polycrystalline panels. The single silicon crystal in the monocrystalline panel does not age and has stable characteristics over the entire service life, only elements that surround the silicon deteriorate with time. And finally, monocrystalline solar panels tend to work better in low light and perform better in warm weather compared to polycrystalline panels. Monocrystalline LONGi solar panels cost a little more than polycrystalline modules, but this gap has decreased lately which makes monocrystalline modules a better choice all around.
Longi Himo4 Key Selling Points
- Sizes 350W-380W
- 25 Year Performance Warranty
Overall, the HiMO4 is larger than the HiMO3 and can produce more power. It also comes with an extra 2 years in product warranty which can go a long way. I would definitely be willing to pay a little bit extra for this solar panel.
I think it would be worth the money, not forgetting the extra solar panel efficiency which can help you pay off your system quicker.

What Solar Panel Modules Does Longi Offer
LONGi offers two main monocrystalline module series, the Hi-MO 4 Monofacial Series and the Hi-MO 5 Bifacial Series, but only the Hi-MO 4 Series offers panels for residential use.
Bifacial solar panels are not practical for residential installations but have gained popularity in commercial applications over the past few years.
There are three models to choose from in the Hi-MO 4 Series, with varying wattage and other features.
A few things to keep in mind when reviewing solar modules: a high efficiency for a solar panel is anything above 21%, with 20% still being excellent. Additionally, the wattage of solar panels generally ranges from 275 W to as high as 400 W per panel.
Jinko And Longi Are The Kings At Fast Roi/payback Periods
When it comes to paying off your system quickly, you have to give Jinko and Longi the credit. Both panels are the kings of fast pay back periods.
Now, if this is something you are looking for then Id highly recommend either of these solar panels because they are extremely affordable and come with good performance. If you compare the Cheetah vs HiMO4 you will see that you might have a slight edge with Longis panel.
Its slightly more efficient, meaning you will get a small amount of extra energy over a 15 year period compared to the Jinko Cheetah panel. However, this is so minor that it wouldnt make much of a difference. But, you know what they say More energy is more savings .
Either way, both of these solar panels will provide you with a really fast return on investment. They are perfect for homeowners who are looking to maximise on solar and take advantage of the solar panel rebate that is available across Australia.

How Does Longi Solars Warranty Stack Up To The Competition
LONGi Solar offers a 12-year limited product warranty for workmanship and defects and a 25-year performance warranty. The product warranty does not cover normal wear and tear or changes caused by normal use of the system: the modules must be installed and used as they are designed to be.
As for the performance warranty, also known as the power output warranty, LONGi warranties the panels for 25 years. At the end of 25 years, LONGi guarantees that the annual output of the solar panels will be at least 84.8% of their original solar energy output at the time of installation. With most solar panel companies, the range is about 80%-90% of the original output, so this number falls in line with the industry average.
Most high-end solar panel manufacturers offer a 25-year warranty for performance and product, LONGi only offers a 12-year product warranty.
You Can Also Future Proof Your Home
Now, heres where it gets really interesting. Not only are you going to be generating more energy which will lead to higher savings. You will also be future proofing your home. One thing homeowners are not considering right now is the amount of energy they will be using in the future. Think about it 10 years ago we barely had smartphones, laptops, air fryers, smart TVs and all of these extra appliances.Fast forward to 2021, everyone in the family has a smartphone AND laptop. Dont forget playstations, VR, microwaves. All of this is plugged in at the same time and consuming energy. The devices batteries are getting bigger and stronger every year meaning they need to consume more energy to be fully charged. Homeowners are using 10 times the amount of energy they were 10 years ago. Dont believe me? We have customers who are ripping off systems that are only 7-8 years old to install a much bigger system that is scalable and can be extended in the future. There is only one way the world is going That is digital. In 10 years time we will be consuming the most amount of energy ever, therefore its best to invest in a system that is large enough to cope with this expansion and will still generate savings in years to come. I cant stress it enough. Future-proof your home. Future-proof your solar system.

Pros And Cons Of Longi Solar Panels
Value for money: 9
Overall Rating: 8.7/10
While the vast majority of manufacturers produce either polycrystalline or monocrystalline solar panels, Longi uses only mono-silicon solar cells to make their solar systems.
Monosilicon panels have a single crystal of silicon that provides more room for electricity flow. Therefore, these solar panels have a higher sunlight conversion rate unlike polycrystalline cells that have multiple crystals.
Longi offers high-quality, reliable and affordable solar panels compared to other solar panels in the same price range. Brands like LG and SunPower are almost double the price of Longi and offer 1-2% more module efficiency than Longi. This means Longi offers a better price and high efficiency modules for homeowners on a budget.
Power Degradation Of Longi Solar Panels
With most of their solar panel models, power degeneration for the first year is less than 2%. LONGi solar panels are meant to provide you quality products at a humble price point, and while achieving that goal, a power degeneration of 2% is nothing.
From the second year up until their lifetime, the solar panels will lose a maximum of 0.55% power. There are models which have a power degeneration rate of 0.45% per annum.
