The Debut Of Maxeon Solar
Maxeon Solar is, at its core, a technology innovation company, said Jeff Waters, future Maxeon Solar CEO. Waters is the current CEO for SunPowers technologies business unit.
Maxeon Solar will be the company responsible for producing the high efficiency solar panels that SunPower is known for. It will be headquartered in Singapore, with factories in France, Malaysia, Mexico, and the Philippines.

Maxeon Solar Cell Technology
Since 2007 when it first began production, SunPower uses a next-generation cell technology, Maxeon, in the manufacture of its panels. Now in its fifth generation launched in 2019 as the Maxeon Gen 5, the Maxeon cell technology is a variant of the IBC cell technology.
Unlike the common monocrystalline and polycrystalline solar cells which has fingers or ribbons mounted on the front of the cell to collect the current generated by the cells, IBC cells has their fingers integrated instead on the rear side of the cell clearing the front of the panels of the thin grid lines found on the surface of panels made using the traditional cell technologies. Removing the front fingers and solder bonds found in conventional cells is a way of increasing efficiency because these fingers and solder bonds can block the cell areas exposed to the sun. Additionally, these fingers can also deteriorate over time and lead to cell failures and power deficits.
In the design of the base IBC cell itself, SunPower uses a grid of N-type and P-type silicon on the rear side. The back-contact IBC cells are built on a base of high purity N-type silicon which also increases performance and has the low degradation rate which justifies SunPower offer of the leading performance warranty of 92% retained capacity after 25 years on two of its third generation panels and on the fourth generation Maxeon Series.
How Much Does It Cost To Install The Sunpower Solar Panels
The SunPower solar panels price depends on various factors like the number of panels, models, other solar components, and installation costs. Below we have added an estimated cost of installing the SunPower solar panels:

Maxeon 2 And Maxeon 3
With the transition from SunPower to Maxeon, the latest generation panels from SunPower named Maxeon 2 and Maxeon 3 has replaced the E and X series. However, they are still available in the market and will be so for a while.
The Maxeon 2 and Maxeon 3 are both made from the Gen 3 IBC cell technology. They both use 104 cells in one module, an upgrade from the 96-cell format used in the A and X Series. This increases their output rating with a 20.4% maximum efficiency. The Maxeon 2 made from the slightly lower IBC cell, have a lower power rating of 340W to 360W, making them also much more affordable but still some of the most powerful residential panels available.
Ibc Solar Cell Technology:
SunPower solar panels use the IBC solar cell technology. IBC stands for Interdigitated Back Contact. IBC is a kind of solar cell that converts energy from the cells through back contact instead of the typical front contact. Unlike regular solar panels, the IBC solar cell technology allows the entire front part of the solar panel to absorb energy from the sun without leaving any space.
Regular solar panels contain metal ribbons on the front part of the solar panels, which convert energy. But the issue with the metals ribbons is that it takes additional space and tends to expand when exposed to sunlight. This causes solar panel shading issues, one of the most common reasons for efficiency loss.

Sunpower And Sma Choose To Manufacture In China
High end manufacturers SunPower And SMA have chosen to manufacture in China. But they arent exactly advertising the fact.
China produces far more solar panels, far more solar inverters, and god knows how many more batteries than any other country in existence. China has been called the workshop of the world1 and has repeatedly shown itself to be capable of producing high quality, reliable goods.
As examples, the majority of solar panels produced in China are tier one, which means major financial organizations trust them for use in large scale solar projects with an expected lifespan of 25 or more years. Some solar inverters manufactured in China are considered among the best in the world, and the lithium battery with the longest warranty I am aware of is made in China.
On the other hand, China also makes some absolute rubbish.
This rubbish includes solar panels that deteriorate in sunlight faster than a sparkly vampire and inverters that are about as reliable as a paper condom.

Sunpower Solar Panels Review:
If youre in the market for solar panels, then Im pretty sure you would have heard of SunPower solar panels. They are one of the oldest solar panel manufacturers and are extremely popular in America, where they are known to be American made and manufactured.
Now, over the past 10 or more years SunPower has become one of the biggest solar suppliers in Australia. The demand is huge, homeowners just cannot get enough of these all black solar panels.
In the past few years, SunPower has become one of our top selling solar panels. This year, I think they will actually become our best seller But its not for the reasons you would expect.
You see, SunPower did something amazing last year that has changed the solar industry forever. Seriously, this has made them become one of Australias most popular solar panels.
But honestly, are these solar panels actually any good?
SunPower seems to have gained the reputation of high-end solar panels, meaning they provide high quality products at a high cost But is this really true?
Well, lets find out. We are going to be taking a dive into this SunPower solar panels review to see if they are really worth your money or if you can get better value elsewhere.

The Photovoltaic Affect Monocrystalline Polycrystalline And Thin
Solar photovoltaics are made with a number of parts, the most important of which are silicon cells. Silicon, atomic number 14 on the periodic table, is a nonmetal with conductive properties that give it the ability to convert sunlight into electricity. When light interacts with a silicon cell, it causes electrons to be set into motion, which initiates a flow of electricity. This is known as the photovoltaic effect.
However, silicon cells alone cant provide electricity for your home. They are paired with a metal casing and wiring, which allow the solar cells electrons to escape and supply useful power. Silicon comes in a number of different cell structures: single cell , polycrystalline or amorphous forms, most commonly associated with thin film solar panels.
What About Sunpower’s Company Ethics
Ethically, SunPower seems to want to make the industry a better place for homeowners. It does look like they are trying to make solar more affordable for consumers and not just focusing on money as their main goal.
Its also worth noting a bit of extra information regarding Dr Richard Swanson. He was the person behind Swansons Law. This suggests that solar panel costs will fall 20% for every time that production capability is doubled. Were certainly on the right track to affordable solar energy every single day

Sunpower Solar Panels Warranty
Unlike most solar panel manufacturers, SunPower stands behind their product with a strong warranty. No matter whether youre buying their residential, commercial or portable solar panel, youre going to get warranty for extra peace of mind.
In case your panel gets failed due to any manufacturing defect or environmental issue, the SunPower team is there to help you out.
Most solar panel companies offer a 10-year material warranty while even SunPowers basic solar panel comes with a 25-year warranty against any defects. Isnt it great?
Bottom Line: Your Choice May Come Down To Price And Installer Choice
If you compare the product offerings of these two companies, youâll see that they stack up very favorably against each other. While there are slight differences in performance between panels in each of these product categories, they arenât large enough to base your product decision on.
Instead, if offered a choice, you can probably safely make your decision based on the best price.
Another consideration is that both SunPower and LG offer certifications for installers who have met certain criteria, such as training requirements and having a good track record with a sufficiently high volume of installations.
SunPower has Authorized Dealers for companies that have met minimum requirements for training and customer satisfaction, and Elite Dealer and Master Dealer designations that meet more stringent standards.
LG, meanwhile, has LG PRO and PRO Platinum designations for their certified installer network.
If your installer has one of these certifications, thatâs a good sign, and it should factor into your decision if youâre choosing between these two manufacturers.
One last consideration: if buying American-made products is important to you, find out from your installer if they can tell you if your LG NeON panels were sourced from the Alabama factory or overseas. Ironically, itâs the South Korean LG and not the US-based SunPower that does any manufacturing in America.

High Performance: Lg Neon R Vs Sunpower X
At the high end of the product lineup for these companies are the LG NeON R series and the SunPower X-Series panels. With these panels, SunPower and LG use their best technology to maximize efficiency and power output. Both the NeON R and X-Series use rear contact solar cells to increase power output.
In a conventional solar cell, there are fine wires called busbars and fingers that form a visible grid on the front of each cell. Having lots of wires reduces power loss because electrons in the silicon cell donât have to travel as far to reach a conductive wire, but at the same time this increases power loss because the metal wires block sunlight from reaching the photovoltaic material underneath.
In the end, both the LG and SunPower panels end up with greater than 21% efficiency, placing them at the high end of performance among all panels on the market.
|Warrantied output after 25 years||90.8%||92%|
You might notice that the LG panels have a higher maximum output. This isnât due to higher efficiency, but because the NeON R panels are slightly larger.
As you can see, the X-Series outperforms the NeON R in all three categories, but only very slightly. The performance is close enough that you can consider these panels to be equal, which means that other considerations – particularly price – should be the deciding factor. On a tight roof, the slight difference in panel size might also be a factor.

How Solar Panels Are Made
Solar panels are made of monocrystalline or polycrystalline silicon solar cells soldered together and sealed under an anti-reflective glass cover. Once light hits the solar cells, the photovoltaic effect starts, and electricity is created. The five key steps in making a solar panel are:
1. Make the solar cells
2. Solder solar cells together to create a panel
3. Install a backsheet, front glass layer, and frame
4. Install a junction box
5. Quality testing
