Longi solar panels: expert review 2021

PV Evolution Laboratorieswith the support ofDNV GLindependently test the reliability of the solar panel. The tests are voluntary, and solar panel manufacturers pay to participate in the tests. This testing procedure is internationally recognized and is an accurate reflection of solar panel performance.

LONGi is considered the best in all 6 tests in the latest report.

Where Longi solar panels are manufactured

Most of the manufacturing takes place in China and is then shipped around the world. Longi, on the other hand, has factories in India, Vietnam and Malaysia. This is understandable because the labor force in these countries is much cheaper. And this is a significant reason why longi solar panels are so cheap. That doesn't mean they sacrifice quality. Based on their history, customer reviews and overall dedication to their craft, it is clear that they are committed to providing high quality green energy solutions to the general public.

They have offices in many countries, including Longi Solar Panels in Australia, Japan, USA and South Korea, and so on. Its headquarters are in Sydney, Australia.

Which mount is suitable for Longi solar panels

When installing LONGi solar panels, you should pay attention to the place of installation and, in the case of roof installation, the roof material.

First, it is necessary to choose the most suitable and correct place for installing solar panels. If the type of grounding suits you, there are two types of grounding: standard grounding and pole mounting. Standard ground mounting uses a metal frame that is bolted into the ground to hold the solar modules. Pole mounting is considered the most reliable mounting type and can contain multiple panels.

If you plan to use the roof for laying panels, then you should think not only about the method of fastening, but also about the material of the roof. Most roofing materials are suitable for LONGi solar panels, with metal roofs being the best choice and slate roofs not being ideal.

Longi Solar has certainly made great strides in recent years.

After being the world's largest producer of monosilicon modules, opened 20 years ago, in 2000.

Longi has taken the technology under its own brands to new heights and is quickly becoming known as one of the best solar panel manufacturers in the world.

For the past two years, they have.

• It broke the world record for cellular efficiency. 3 times.
• Number 1 in the world for Bloomberg list one.
• They have gained a considerable reputation for providing inexpensive yet highly efficient solar panels.
• Received a very high rating in independent DNV tests.
• Passed the MAST test for the durability of the back panel.

The new Longi Hi-Mo X seems to be no exception to that.

It has an incredible 350 watts of power in the size of a regular solar panel. This puts it in line with more expensive brands like LG and Sunpower for high efficiency at about half the price of their competing power-class brands.

The solar panel itself also has an elegant design that is aesthetically pleasing. Its all black monochrome Tile design withblack framesit is definitely one of the most beautiful solar panels on the market today.

Longi also received CEC accreditationMASTER; MASTERprogram

This is given to solar panels that have passed additional tests such as DNV PVEL, the James Cook University cyclone test and a series of durability tests.

Very few panels have this distinction.

Longi 370w Mono Perc Solar Panel Review

The LONGi 370w mono PERC panels are the specific panels we have experience with, so we will focus on them. This board has "PERC", which is really just a fancy name for passivated emitter return contact. For now, we can report that this board lives up to expectations, but it's also a game changer. It is the first large 300W standard size monochrome panel also at a price similar to polyethylene panels.

So what is PERC?It's hard for most people to imagine what it's all about, but let's try anyway. PERC improves the board's ability to capture more light near the back surface, extracting more energy. PERC was first developed by the University of New South Wales in 1983, so it has a lot to brag about! His approach has also proven to be the best way to achieve high efficiency. As a result, UNSW has used it to achieve several world records of close to 25%.

The LONGi 370w panel comes straight off the pallet and looks like the goods. A nice solid black 40mm bezel also holds everything together. However, you would expect the first level board to look like this.

Why it is so important to use the best solar panel brands

What we keep repeating at SolarReviews is that solar panels last a very, very long time, 25 to 30 years to be exact. This is why it is important to buy solar panels of the following qualities:

• Least likely to fail.

• The manufacturer will honor its warranty if a malfunction occurs.
• It was installed by a local solar company who will continue to operate if a failure occurs and perform the necessary tests to successfully submit a warranty claim to the manufacturer.

This third point is very important in practical terms and a good reason why it is not always wise to buy solar energy from the cheapest company.

How long is the warranty for Longi solar panels?

All LONGi solar panels come with a 10-year product warranty on materials and workmanship and an additional 25-year linear power output warranty. If you need to get in touch with LONGi solar, the representative office in the USA is always at your service.

What types of cells for Longi solar panels are best

Monocrystalline solar cells are considered the best type of solar cells. They are made from a single crystal of silicon and therefore have a much higher efficiency and more elegant aesthetics compared to polycrystalline cells. Monocrystalline solar panels are known to be the most efficient solar panels on the market with an efficiency of over 22%. Thanks to their efficiency, monocrystalline panels are the most space-efficient panels and take up less space than any other solar panel. Also, monocrystalline panels are more durable and have a longer service life than polycrystalline panels. Monocrystalline silicon in a monocrystalline panel does not age and has stable characteristics throughout its working life, only elements that include silicon deteriorate over time. And finally, monocrystalline solar panels perform better in low light and perform better in hot climates compared to polycrystalline panels. Monocrystalline LONGi solar panels cost a little more than polycrystalline modules, but that gap has decreased recently, which makes monocrystalline modules a better choice.

Longi Himo4 Main sales points

• Sizes 350W-380W
• 25-year performance guarantee

Overall, HiMO4 is larger than HiMO3 and can produce more energy. It also comes with an additional 2 years of product warranty, which can go a long way. I would definitely be willing to pay a bit more for this solar panel.

I think it would be worth the money, not forgettingadditional efficiency of solar panelswhich can help you pay off your system faster.

Which solar modules does Longi offer?

LONGi offers two main series of monocrystalline modules, the Hi-MO 4 Monofacial series and the Hi-MO 5 Bifacial series, butonly the Hi-MO Series 4 offers panels for residential use.

Bifacial solar panels are not practical for residential installations, but have gained popularity in recent years in commercial applications.

In the Hi-MO 4 series, you can choose between three models, with variable power and other features.

Some things to keep in mindwhen inspecting solar modules: ahigh efficiency for solar panelis anything above 21%, with 20% still excellent. In addition, the power of solar panels usually varies from275W to 400W after panel.

Jinko and Longi are the kings of fast ROI/payback time

When it comes to paying off your system quickly, you have to give credit to Jinko and Longi. Both boards are kingsquick payback periods.

Now, if that is something you are looking for, I would recommend any of these solar panels as they are extremely affordable and perform well. If you compare the Cheetah and the HiMO4, you'll see that it might have a slight edge with the Longis panel.

It's a bit more efficient, meaning you'll get a small amount of extra power over a 15-year period compared to a Jinko Cheetah board. However, it is so small that it would not make a big difference. But you know what they sayMore energy means more savings.

In any case, these two solar panels will give you a very quick return on investment. They are perfect for homeowners looking to maximize their solar energy and take advantage of the solar panel discount available across Australia.

How the Longi Solars warranty compares to the competition

LONGi Solar offers a 12-year limited product warranty for labor and defects and a 25-year performance warranty. The product warranty does not cover normal wear and tear or changes caused by normal system use: the modules must be installed and used as designed.

Regarding the performance guarantee, also known as the power output guarantee, LONGi guarantees the panels for 25 years. At the end of 25 years, LONGi guarantees that the annual production of the solar panels will be at least 84.8% of their original solar energy at the time of installation. For most solar panel companies, the range is around 80% to 90% of original output, so this number is in line with the industry average.

Most top solar panel manufacturers offer a 25-year product and performance warranty, LONGi only offers a 12-year product warranty.

You too can prepare your home for the future.

Now, this is where it gets really interesting. Not only will you generate more energy, which will lead to greater savings. You will also be preparing your home for the future. One thing that homeowners don't consider right now is how much energy they will use in the future. Think about it10 years agowe hardly had smartphones, laptops, deep fryers, smart TVs and all those extra gadgets. Fast forward to 2021, everyone in the family has a smartphoneElaptop. Don't forget playstation, VR, microwave ovens. All of this is connected at the same time and consumes energy. Device batteries are getting bigger and stronger year by year, which means they have to consume more energy to be fully charged. Homeowners use 10 times more energy than 10 years ago. Don't believe me? We have customers who aretheft systemswho are only 7-8 years old to install verya larger system that is scalableand may be extended in the future. There is only one way the world goes. It's digital. In 10 years we will be consuming the most energy ever, so it is best to invest in a system that is large enough to handle this expansion and still deliver savings in the coming years. I cannot stress this enough.Prepare your home for the future. Prepare your solar system for the future.

Pros and cons of Longi solar panels

professionals

Value for money: 9

Overall rating: 8.7/10

While the vast majority of manufacturers produce polycrystalline or monocrystalline solar panels, Longi uses only mono-silicon solar cells to produce its solar systems.

Monosilicon boards have a single silicon crystal that provides more space for electricity to flow. So these solar panels have a higher conversion rate of sunlight unlike polycrystalline cells which have more 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 cost almost twice as much as Longi and offer 1-2% more module efficiency than Longi. This means Longi offers better value and high efficiency modules for homeowners on a budget.

Energy degradation of Longi solar panels

fronus 3.6kw with longi 540 watt solar panels

With most of their solar panel models, the energy degeneration in the first year is less than 2%. LONGi solar panels are intended to provide quality products at a modest price, and to achieve that goal, a power degeneration of 2% is nothing.

From the second year to the useful life of the solar panels will lose a maximum of 0.55% of energy. There are models that have an energy degeneration rate of 0.45% per year.
