    Company background

    SunPower Corporation has a rich history in solar manufacturing and has long been regarded as the solar industry technology leader. This is a very big claim, but it’s hard to disagree as they currently produce the most efficient residential solar panel, the Maxeon 3, with the lowest degradation and best performance warranty on the market. Although, like most things, high performance comes at a high price, and SunPower panels are some of the most expensive in the world.

    SunPower started in a lab in the early ’80s and officially became SunPower in 1988. After securing funding from investors, the R D team developed record-breaking PV cells using advanced cell technology, which were later used by the NASA space program along with Honda to win the world solar challenge car race in Australia. These achievements put SunPower on the world stage as one of the leading solar cell manufacturers and laid the foundation for the high-efficiency Maxeon IBC cells used today. SunPower has expanded and built advanced facilities in the US, Mexico, Europe, Malaysia, China and the Philippines to manufacture high-efficiency solar panels. However, it hasn’t always been smooth sailing. Over recent years, the company has run into financial issues. It racked up considerable debt due to high overhead costs and pressure from the highly competitive Chinese and Korean panel manufacturers. The financial troubles forced SunPower to restructure its business and manufacturing operations, and now the financial situation is looking positive. See detailed company analysis in this article from PV-Tech.

    SunPower Splits into two companies.

    In 2019, Sunpower announced it would separate into two independent public companies. SunPower and Maxeon Solar, each focusing on a different market segment.

    • SunPower will FOCUS purely on the North American Solar market with distribution, sales and installation of solar panels, energy storage and associated products.
    • Maxeon Solar or ‘Maxeon Solar Technologies’ will become the global developer, distributor and manufacturer of the SunPower Maxeon cells and Solar panels range.

    Maxeon IBC cells

    SunPower began mass production of the high-performance IBC or Interdigitated Back Contact cells back in 2007 and has led the industry ever since using what is considered the most efficient solar cell technology available today. Unlike the common monocrystalline and polycrystalline solar cells, which use front-mounted busbars and fingers to collect current, IBC cells have a fine grid of conductors integrated into the rear side of the cell. The IBC cell design, which SunPower refers to as ‘Maxeon’, uses a grid of N-type silicon on the rear side, which increases efficiency by eliminating the need for front exposed busbars that partially shade the cell. The SunPower IBC cells are built on a base of high-purity N-type silicon that increases efficiency and performance and offers a very low rate of degradation, this is the basis of SunPower’s leading performance warranty of 88.25% retained capacity after 40 years, on the Maxeon series panels.

    The current generation (3 4) IBC cells from SunPower use the smaller format 5” (125mm x 125mm) size configured in a 96-cell layout with 8 rows of 12 cells. Almost all other manufacturers have moved to the 6” (156mm x 156mm) cell size which makes up a common 60 cell panel. Cell size doesn’t affect performance, but more cells do equate to a higher voltage which can be problematic for domestic installations with a voltage limit of 600V (depending on the country). A higher voltage means fewer panels can be linked together in a string before reaching the upper voltage limit.

    Shingled Cells

    Shingled cells are a proven technology that uses overlapping thin cell strips assembled horizontally or vertically across the panel. The SunPower P series panels, described in more detail below, use the vertical format with 6 long cell strips in parallel. This offers several benefits, including improved shade tolerance when partially shaded, as each long cell works independently. The thin shingled cells are also more flexible and less prone to micro-cracking, a common issue with conventional full-size square cells. These are made by laser cutting a normal full-size cell into 5 or 6 strips and layering them in a shingle configuration using rear-side conductive adhesive. The slight overlap of each cell strip hides a single busbar that interconnects the cell strips. This unique design covers more of the panel surface area and doesn’t require front-side busbar connections, which partially shade the cell, thus increasing the panel efficiency, much like IBC cells.

    The P series uses conventional P-type silicon, which is not as efficient as the high-performance N-type silicon used by the Maxeon IBC cells. However, it is much more cost-effective and still achieves a respectable efficiency of 20.4%. The P series is also backed by the SunPower 25 manufacturer’s warranty.

    The SunPower Range

    While the renowned Maxeon series panels are some of the world’s best-performing panels, SunPower’s more cost-effective Performance series offers a diverse range of panels for residential, commercial and utility-scale solar installations. The Maxeon 2 and 3 series panels replaced the previous E and X series, which used the same high-efficiency IBC cells to compete in the premium end of the market. The latest generation 5 and 6 series (M-series) panels are AC panels with built-in microinverters from Enphase Energy. These next-gen panels feature a new larger cell design making them the most powerful and efficient panels released from the company. The price-competitive performance or P-series panels use the unique overlapping shingle cell design and complete more in the commercial market.

    Maxeon 3

    The Maxeon 3 is the flagship of the SunPower range and is available in sizes from 400 to 440W for residential installations. The Maxeon 3 series is built using the Gen 3 level cells using a larger 112-cell format to increase power and tops the range with an impressive 22.8% maximum efficiency, making it one of the most efficient solar panels available.

    Maxeon 2

    Like the Maxeon 3, the Maxeon 2 panel is based on the Gen 3 high-performance IBC cell technology and uses the same 104-cell format to increase power output further and tops the range with a 20.4% maximum efficiency. However, as it is based on the slightly lower-spec IBC cells, the Maxeon 2 panels have a lower power rating of 340 to 360W, making them more affordable but still some of the most efficient residential solar panels available.

    See the full SunPower Maxeon 2 Specification datasheet here

    Maxeon 5 Series

    SunPower’s next-generation A series AC panels and the new Maxeon 5 series are built on what Sunpower refers to as the Next Generation Technology IBC (Interdigitated Back Contact) ‘Gen 5’ cells. These new larger format 6” IBC cells are fabricated on a new line at its manufacturing plant in Malaysia. The new design is used to produce panels rated from 390W to 415W making them some of the most powerful residential panels currently available. The alternative A series version of the Maxeon 5 panel incorporates a microinverter from Enphase Energy.

    See the full SunPower Maxeon 5 Specification datasheet here

    Maxeon 6 Series

    M-series in North America

    The latest panels from SunPower released in 2022 are the Maxeon 6 range. Known as the M-series in North America, they are built on the same 66-cell format as the five series but use the next generation Maxeon 6 cells to boost efficiency to a record-breaking 22.8%, making this the most efficient solar panel manufactured for residential use. The new 6 series panels are slightly larger than the five series, coming in at 1032mm wide by 1872mm high. Naturally, power output has also boosted with a 6% increase taking the peak power rating from 415W to 440W. Like the 5-series, the A series version of the Maxeon 6 panel incorporates an Enphase Energy microinverter. To cater for the commercial market, the Maxeon 6 will also be available in a larger 72-cell format with increased power ratings from 450W to 475W.

    • Maxeon 6 (AC) series – 66 cell – 420 to 440W. IBC N-type cells (Gen 6)
    • Maxeon 6 Commercial series – 72 cell – 450 to 475W. IBC N-type cells (Gen 6)

    See the full SunPower Maxeon 6 AC Specification datasheet here

    Performance Series

    As described in detail earlier, the Performance series, or P series panels, use a unique shingled cell design with 6 long strings of shingled cells in parallel. This design is more cost-effective and offers additional shade tolerance when partially shaded. The thin single PERC cells, based on standard P-type silicon, are more flexible and less prone to micro-cracking, which is a common issue with conventional full-size square cells. The P series is available in three varieties, with the smaller residential panels rated from 370W up to 390W, the larger format commercial panels available in 405W to 420W power ratings, and the extra-large utility size panels available from 475W to 500W.

    • P Series Residential panels. 330W to 390W. Shinged cells
    • P Series Commercial panels. 405W to 420W. Shingled cells
    • P Series Utility size panels. 475W to 545W. Shingled cells

    Despite being based on standard P-type silicon, SunPower still offers an impressive 25-year performance warranty as well as a 25-year manufacturer’s warranty on all P Series panels.

    Sunpower U Series

    The U series is the entry-level panel from Sunpower, which is currently sourced from Waaree Energies Ltd, one of the leading Indian solar panel manufacturers. The Waaree Arka series are split cell panels rated at 380W to 420W featuring common Mono PERC cells. While a large reputable manufacturer makes them, they do not have the same efficiency or lifespan as the high-performance Maxeon series panels. The Waaree Arka series is backed by a 25-year warranty.

    Warranty and service

    In a surprising announcement, SunPower Maxeon Technologies decided to increase its product and performance warranty on the Maxeon range of panels from 25 years to an incredible 40 years, making it the industry’s most extended solar panel warranty by a decade. The company is confident it can support the extended warranty based on a detailed failure analysis program which reported an extremely low 0.005% return or failure rate based on the warranty claim data from the 15 million panels sold over the last few decades.

    The new 40-year warranty guarantees a minimum power output of 88.3% in year 40, meaning power output will only degrade by around 0.25% per year over the warranty period. Maxeon claims this is attainable due to the proven long-term reliability and performance of Maxeon IBC cells built on a unique patented metal foundation. This durable cell structure can withstand high thermal stresses and dissipate more heat, meaning they are not as suspectable to hot spot formation or micro-cracks, a common problem with the standard cells most competing panel manufacturers use.

    The Sunpower Performance or P series panels are backed by a 25-year product warranty guaranteeing a minimum of 87.2% power output after 25 years.


    SunPower has long been the industry leader in sustainability and is the only manufacturer we know of that uses a full closed-loop sustainability strategy. SunPower’s philosophy is to drive sustainable business practices at every stage of the product life cycle and beyond. This strategy paved the way for SunPower to become the winner of the first annual Sustainability Award from pv magazine.

    Cradle to cradle certified

    The SunPower Maxeon Panels are the world’s first solar panels to be Cradle to Cradle CertifiedTM, which makes SunPower the world’s leading manufacturer when it comes to sustainability.

    SunPower Battery Systems

    SunPower first entered the highly competitive energy storage market in late 2019 with the Equinox storage system, but in 2021, it was rebranded as SunVault Storage. The company recently released the SunPower Reserve battery energy storage system in Australia, which is the first all-in-one solar and battery energy storage system (BESS) developed by SunPower.

    SunVault Storage

    The SunVault Storage battery system is an AC-coupled battery that can be retrofitted to homes with an existing solar installation. However, unfortunately, SunPower has restricted the system so it can only be installed in homes that use SunPower solar panels. This is a strange move, considering all other AC-coupled batteries, such as the Tesla Powerwall, can be used with any brand of solar panels. The SunVault system comprises a 13kWh or 19kWh battery together with the well-regarded Schnider Electric XW Pro off-grid inverter. The Schnider inverter is a high-performance (transformer-based) inverter capable of supplying 6.8kW of continuous power with an impressive 12kW surge rating, making the SunVault one of the most powerful AC-coupled battery systems.

    The smaller Hub module is the brains of the system and houses the load centre and grid isolation equipment to enable off-grid operation in the event of a grid outage. This configuration is very similar to the well-known Tesla Powerwall 2. However, unlike Tesla, the SunVault uses safer lithium Ferro phosphate (LFP) cells which have become the chemistry of choice for stationary battery storage systems.

    Like the Tesla Powerwall 2 and Sonnen ECO battery systems, the SunVault system is AC-coupled, meaning it is connected directly to the main switchboard (load centre) and can be retrofitted to homes with an existing solar system. However, thanks to the Schneider inverter, the SunVault system has a continuous output power rating of 6.8kW and a very high 12kW surge power rating. Two or three SunVault systems can be connected in parallel for additional energy requirements, providing 26kWh, or 39kWh of usable storage capacity. The 13kWh SunVault system costs slightly more than the competition at US16,000 plus installation.

    SunPower Reserve

    The new SunPower Reserve system, released in Australia, is a complete solar and battery solution. This means it contains a hybrid solar inverter, and the solar panels are connected directly to the system, as opposed to AC-coupled battery systems, which require a separate solar inverter. The inverter is rated at 5kW, with a surge power rating of 7.5kW for 30 seconds, higher than most competing 5kW hybrid single-phase inverters. The total battery capacity is 10.1kWh, and up to 6 battery modules can be connected in parallel for up to 60.5kWh of storage.

    The hybrid inverter contains dual solar (MPPT) inputs with a wide operating voltage range from 100V to 550V, a high input current rating of 15A, and an Isc rating of 18.75A, making it compatible with the more powerful, high-current solar panels now available. The inverter and battery are both covered by a 10-year warranty. However, the battery is limited to 2.92MWh of energy throughput, meaning it cannot be discharged below 20% SOC (State of charge) on a daily basis. This is not uncommon for battery manufacturers, as a full discharge below 20% on a regular basis is known to reduce battery life. See the full SunPower Reserve warranty here. Being a very new battery system, we have limited real-world feedback from solar installers and users. However, considering SunPower generally only produces high-performance, reliable products, it can be assumed that the new Reserve battery system will meet these high expectations.

    SunPower is widely regarded as a world-leading solar panel manufacturer, and very few companies can compete at the same level of performance and quality. SunPower may no longer lead the world in terms of outright efficiency. But it should be remembered that the Maxeon panels were the most efficient solar panel with the lowest degradation and best performance warranty for well over a decade. Not surprisingly, the Maxeon panels are also the most expensive on the market. However, like most things, quality comes at a price. Considering that solar is a long-term investment, the higher price equates to better performance, improved reliability, and more energy generation over the system’s life.

    The financial issues faced by SunPower over recent years raised some concerns over the ability of SunPower to honour its long-term warranty commitments. Despite this, SunPower is generally ranked number one in the US and many parts of the world by installers and customers. In other markets like Asia and Australia, SunPower does not have the same presence, and the very high price of the Maxeon series can be difficult to justify when some other manufacturers offer similar performance and quality at a lower price. That being said, there is no other manufacturer that can match the new 40-year SunPower product and performance warranty.

    The Performance series panels have also been very successful in the commercial solar sector, being very cost-effective and backed by one of the best warranties available. With the improving financial outlook and the next-generation Maxeon 5 and Maxeon 6 series (M-series) panels now available, it looks like SunPower may continue to be an industry leader for some time to come.

    SunPower will no longer manufacture solar panels. here’s why

    SunPower Corporation (SunPower) has announced its plan to split into two separate companies.

    SunPower will continue to be a distributed generation energy services company while their new company, Maxeon Solar Technologies (Maxeon Solar), will FOCUS on the manufacturing of solar panels.

    Why the sudden split? How will it affect the solar market? Will it make an impact on the amount customers pay for solar panels? We answer these questions, and more.

    SunPower Corporation’s split from manufacturing

    SunPower and Maxeon Solar are set to separate within the second quarter of 2020.

    The split was made possible by a 298 million investment by Tianjin Zhonghuan Semiconductor Co. (TZS). TZS is a long-time partner of SunPower and one of the world’s leading suppliers of silicon wafers.

    “This transaction will also simplify both organizational structures, lowering costs, while improving efficiency and creating more nimble companies,” said SunPower CEO Tom Werner during a November 11 2019 conference call.

    By dividing into two separate companies, SunPower can FOCUS on expanding the services it offers to consumers.

    The new and improved SunPower

    SunPower provides energy solutions to consumers by helping them design, implement, and monitor their solar projects. Once the companies divide, SunPower will no longer manufacture solar panels. However, it will still continue to supply the same solar services to customers.

    Tom Werner will maintain his role as CEO at the company’s corporate headquarters in Silicon Valley.

    SunPower Corporation has a network comprised of over 500 dealers that it works with. In order to be part of the network, solar installers must complete specialized training courses and meet various installation criteria.

    The company then helps customers get in touch with these dealers in order to facilitate solar projects. SunPower also offers solar leases to assist customers with financing their solar systems.

    The revamped SunPower is aiming to take its services a step further by expanding into the solar battery storage market. Projections indicate that battery storage is slated to become much more common in the coming years, giving SunPower potential to grow significantly in the energy storage sector.

    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 SunPower’s 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.

    The Maxeon 5 solar panel, the highest-efficiency panel on the market. Image source: SunPower

    The new locations will allow Maxeon Solar to take advantage of low-cost manufacturing processes throughout Asia. Plus, the partnership with TZS provides Maxeon Solar with access to TZS’s supply chain ties.

    These factors will cause the cost of Maxeon solar panels to drop.

    What’s on the agenda for Maxeon Solar?

    One of the manufacturer’s first projects includes the development of the new Maxeon 6 solar panel. Early plans suggest that the model will be built through simple, low-cost manufacturing processes.

    The processes would bring down the price of the panel while still maintaining a solar cell efficiency of 26%.

    Comparing solar panel cost and solar cell efficiency for past and future Maxeon solar panels. Image source: SunPower

    SunPower and Maxeon are expected to enter into a multi-year exclusive supply agreement that will guarantee the deployment and distribution of Maxeon solar panels throughout the U.S.

    However, Maxeon Solar is setting its sights beyond the U.S. and Canada, as it looks to enter the global market, as well. By taking advantage of cheap manufacturing, they can produce low-cost, high efficiency panels while becoming a global competitor.

    SunPower likely didn’t take advantage of cheap overseas manufacturing due to the tariffs imposed on imported solar modules by the Trump administration. Maxeon Solar realized that in order to be successful outside of the U.S., they must manufacture cheap solar panels, which is much more feasible when done internationally.

    How does the Sunpower split impact investors?

    SunPower Corporation is a publicly traded company, meaning that its ownership is organized by stocks, which are owned by investors. Current shareholders will receive a 71% stake in Maxeon Solar when the company becomes public.

    SunPower’s stocks have fluctuated quite a bit in the past. After the announcement of Maxeon Solar, SunPower’s stock value increased by about 15%. They eventually fell back down to just about 1% higher than the previous value.

    As of November 20, 2019, its stock is valued around 8.53.

    Changes in SunPower’s stock value from November 2018 through November 2019. Image source: Yahoo Finance

    By splitting in two, each individual company will be able to streamline operations and lower their costs. Lower costs should lead to SunPower seeing higher profits.

    After seeing profits increase in the third quarter of 2019, SunPower’s stocks also increased, which suggests that if the newly structured SunPower has higher profits, it could increase the value of their stocks, as well.

    What does this mean for the solar industry?

    If Maxeon Solar is successful in expanding into the global market, they could seriously shake up the solar industry. The Maxeon 5 panels that are currently available are some of the most efficient solar panels on the market.

    Maxeon Solar could produce high efficiency panels that sell for a competitive price by:

    • Increasing the scale of production;
    • Decreasing the cost of manufacturing; and
    • Deploying solar in international markets.

    This would put pressure on other solar panel manufacturers to bring down their and crank up the efficiency.

    If more manufacturers were creating high efficiency panels at low prices, solar could become much more affordable. This could be the type of change the industry needs, especially with incentives like the federal tax credit expiring in the near future.


    With a climate in crisis, more homeowners are taking control of their energy and embracing a sustainable lifestyle. By prioritizing the customer experience and making solar the most attractive and accessible energy option, we can build a more sustainable future together.

    SunPower designs, sells and installs the most efficient and durable technology on the planet. We’ve spent over 37 years pushing the boundaries of innovation and demanding more of ourselves—never settling on being a conventional solar company.
