Let’s get going…





SunPower is an American energy business established by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was relabelled SunPower. In 1990 the company got funding to begin manufacturing solar batteries. In 1992 began shipping them to customers.
What Is SunPower?
SunPower is known to design, manufacture, and provide a vast array of high-performance solar electric systems across the USA, for commercial and residential purposes.
It is likewise beneficial to mention that NASA likewise has used SunPower’s modern cell technology for their area programs.
Solar That’s Tough Enough for NASA is Tough Enough for Your Roof
However NASA is not the only one who has actually relied on SunPower items. Solar Impulse 2, a zero-fuel airplane, set a world record for ending up being the very first solar aircraft to fly around the globe, likewise utilizes SunPower solar batteries.
There are a lot of case studies out there using SunPower items, from markets, schools, and homeowners, saving millions $$ in the process of going solar.
SunPower has actually just recently decided to convert its manufacturing division into a brand-new company called Maxeon Solar, while SunPower will focus solely on the consumer and service side, setting up solar panels.
The division began with a $298 million financial 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 said throughout a November 11 conference call.
Maxeon Solar will take on production and technological innovation, giving SunPower the ability to focus entirely on expanding its market share versus its competitors, such as Canadian Solar.
Fixing The Problem Of Solar Energy Consumption

SunPower is taken part in the production and sale of photovoltaic panels, and they use a vast array of product selections.
Photovoltaic panel are alternative sources of energy. They are made up of solar batteries that convert sunlight (and not only light) into electricity.
A complete set consisting of photovoltaic panels, inverters, batteries, and controllers is called a Solar Power Plant. All this can be bought from the company.
Additionally, they give an assurance for 25 years, unlike others who provide just 10 years. Likewise, when buying from them, they will bring and set up batteries and everything you need for free.

Products That SunPower Offers
SunPower makes several 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 solar panels. They are optimized for various applications:
A-Series
Do you want to optimize your life time savings? Then SunPower A-Series panels is for you. A-Series delivers the most powerful cell and highest wattage panels you can put 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 small space with fewer panels on your roof.
A solar 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

SunPower X-Series solar panels deliver 44% more power per panel, resulting more power in smaller areas, with less panels. In this manner you can broaden energy production just by using extra roof area to add more panels later on if you desire.
These cutting-edge panels convert more sunlight into electrical energy, producing 75% more energy per square foot over the very first 25 years.
They likewise provide the highest performance available in a residential photovoltaic panel today, at a record-breaking 22.8%.
That suggests property owners get more electrical energy, more versatility, more peace of mind, and lower electricity bills.
E-Series
SunPower E-Series provide 36% more power per panel than conventional panels. Put simply, they convert more sunlight into electrical power
E-Series are constructed with Maxeon solar batteries, delivering up to 20% efficiency and comes in 435W, 320w, or 327w choices.
P-Series
SunPower P-Series are constructed with an ingenious shingled design solar cells that gets rid of a lot of the dependability challenges of traditional front contact panels.
P-Series panels provide 7% higher panel effectiveness and up to 19 %more energy over the very first 25 years of operation.
But that is not all: SunPower Performance Series( P-Series) panels were called as a leading entertainer in all those five dependability tests conducted by DNV GL, the world’s biggest resource of independent energy specialists and certification body. Those tests consist of:
- Thermal cycling
- Damp heat
- Humidity-freeze
- Dynamic mechanical load
- Potential induced degradation
Advantages Of SunPower Solar Panels
There are numerous advantages of going solar by using SunPower items:
Experience
SunPower has remained in solar energy company for more than 35 years. The business was founded in 1985. Since then, SunPower has been perfecting solar panels for industrial and domestic market. In this industry and numerous others, there are a lot of business that go and come.
Because the financial investment in solar panels is substantial, you much better trust on a company that has proved to be here for many years.
Efficiency
Among the most essential consider catching solar energy is the performance rating of a panel. Not all photovoltaic panels are the same. A greater performance rating implies less panels to catch the same amount of energy.
SunPower uses an industry leading 22.8% performance rating, which is roughly 60-70% higher than the competition.
Sturdiness
Solar panels are a significant investment for both, house owners and industrial businesses. So, they need to understand that they will last. SunPower panels surpassed rivals in dependability, energy production, degradation rates, and shading impact.
SunPower panels are built with long lasting covers to eliminate UV degradation, copper structures for additional strength, and they use a single 25-year service warranty that covers the entire panel and all its parts.
Ecologically Safe
SunPower solar panels are environmentally friendly. Any person who is not indifferent to the health of the planet, naturally, will consider his duty to buy safe energy sources. Many people stop at wind turbines, the problem with them is they give off special noises; photovoltaic panels are quiet.
Other people pick any photovoltaic panels that are out there in the market. Nevertheless, the situation here resembles that of electrical lorries: the batteries are eco-friendly, but they use toxic harmful compounds in the process of their production of batteries, power plants, conductors, and so on. As a consequence, they end up polluting the environment.
Sustainability
SunPower has actually long been the industry leader in sustainability and uses a complete closed loop sustainability technique. Their approach is to drive sustainable organization practices at every stage of the product life cycle and beyond.
