Let’s get going…





SunPower is an American energy business founded by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the business received funding to begin producing solar cells. In 1992 started delivering them to consumers.
What Is SunPower?
SunPower is understood to design, manufacture, and provide a wide variety of high-performance solar electrical systems throughout the USA, for residential and business purposes.
It is likewise worthwhile to discuss that NASA also has actually used SunPower’s cutting edge cell technology for their space programs.
Solar That’s Tough Enough for NASA is difficult Enough for Your Roof
However NASA is not the only one who has actually trusted SunPower products. Solar Impulse 2, a zero-fuel plane, set a world record for becoming the very first solar plane to fly all over the world, likewise utilizes SunPower solar batteries.
There are plenty of case studies out there utilizing SunPower products, from industries, schools, and property owners, conserving millions $$ in the process of going solar.
SunPower has recently decided to transform its production division into a brand-new company called Maxeon Solar, while SunPower will focus solely on the customer and service side, installing photovoltaic panels.
The department started with a $298 million investment by SunPower’s partner and the world’s leading provider of silicon wafers, Tianjin Zhonghuan Semiconductor Co. (TZS).
Why The Creation Of Maxeon Solar?

The objective is to optimize the core operations of the two companies without mixing them. “This transaction will also simplify both organizational structures, reducing costs, while improving efficiency and creating more agile businesses,” SunPower CEO Tom Werner stated throughout a November 11 conference call.
Maxeon Solar will take on production and technological innovation, giving SunPower the capability to focus solely on broadening its market share versus its rivals, such as Canadian Solar.
Solving The Problem Of Solar Energy Consumption

SunPower is participated in the production and sale of photovoltaic panels, and they use a wide range of item choices.
Photovoltaic panel are alternative sources of energy. They are made up of solar batteries that transform sunshine (and not only light) into electrical energy.
A total set consisting of photovoltaic panels, batteries, controllers, and inverters is called a Solar Power Plant. All this can be bought from the business.
Moreover, they offer a warranty for 25 years, unlike others who provide only 10 years. Also, when purchasing from them, they will bring and install batteries and everything you need totally free.

Products That SunPower Offers
SunPower makes numerous items, all related to solar power, like solar panels, total systems, solar cells, total roof-integrated solar systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower uses four series of photovoltaic panels. They are optimized for different applications:
A-Series
Do you want to optimize your life time savings? Then SunPower A-Series panels is for you. A-Series provides the most powerful cell and highest wattage panels you can place on your roof.
SunPower presented the world’s first 400-watt photovoltaic panel, which means you can have more power than ever before in a little space with less panels on your roofing.
A photovoltaic panel is only as good as the cells inside. The A-Series panels utilize SunPower® Maxeon® Gen 5 solar batteries, which are 65% larger than previous generations. This indicates
X-Series
SunPower X-Series photovoltaic panels provide 44% more power per panel, resulting more power in smaller spaces, with less panels. By doing this you can expand energy production merely by utilizing additional roofing system space to include more panels later if you want.
They also provide the greatest performance readily available in a residential photovoltaic panel today, at a record-breaking 22.8%.
That indicates house owners get more electricity, more flexibility, more assurance, and lower electricity bills.
E-Series
SunPower E-Series deliver 36% more power per panel than conventional panels. Basically, they transform more sunlight into electricity
E-Series are developed with Maxeon solar cells, delivering up to 20% effectiveness and comes in 320W, 435w, or 327w alternatives.
P-Series
SunPower P-Series are developed with an innovative shingled style solar cells that gets rid of a number of the dependability challenges of traditional front contact panels.
P-Series panels provide 7% higher panel efficiency and up to 19 %more energy over the first 25 years of operation.
However that is not all: SunPower Performance Series( P-Series) panels were called as a top performer in all those 5 reliability tests performed by DNV GL, the world’s biggest resource of independent energy professionals and accreditation body. Those tests include:
- Thermal cycling
- Damp heat
- Humidity-freeze
- Dynamic mechanical load
- Potential induced degradation
Advantages Of SunPower Solar Panels
There are lots of benefits of going solar by utilizing SunPower products:
Experience
SunPower has been in solar energy company for more than 35 years. The company was founded in 1985. Ever since, SunPower has been improving solar panels for industrial and residential market. In this industry and numerous others, there are a lot of business that come and go.
Since the financial investment in solar panels is significant, you much better trust on a company that has proved to be here for many years.
Performance
Among the most essential factors in recording solar energy is the efficiency score of a panel. Not all photovoltaic panels are the same. A higher performance score implies fewer panels to record the exact same quantity of energy.
SunPower uses an market leading 22.8% effectiveness ranking, which is approximately 60-70% higher than the competition.
Durability
Solar panels are a significant financial investment for both, house owners and business companies. So, they require to understand that they will last. SunPower panels exceeded rivals in reliability, energy production, degradation rates, and shading impact.
SunPower panels are constructed with durable covers to get rid of UV destruction, copper structures for added strength, and they use a single 25-year warranty that covers the entire panel and all its elements.
Ecologically Safe
SunPower solar panels are eco-friendly. Any person who is not indifferent to the health of the world, naturally, will consider his task to buy harmless energy sources. Many people stop at wind turbines, the issue with them is they discharge special sounds; photovoltaic panels are quiet.
Other people choose any photovoltaic panels that are out there in the market. However, the scenario here resembles that of electrical automobiles: the batteries are eco-friendly, however they use poisonous damaging substances in the process of their production of batteries, power plants, conductors, and so on.
