Are you tired of paying substantial electrical energy costs month after month? Going solar is your best bet for huge cost savings, and now, thanks to SunPower, it is more affordable and much easier than ever before.
This is what you will discover:
- What is SunPower
- The cons and pros of SunPower and going solar
- Where to purchase
- Evaluations from actual clients
Let’s get started…





SunPower is an American energy company founded by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the business got moneying to start producing solar batteries. In 1992 began shipping them to customers.
What Is SunPower?
SunPower is understood to design, manufacture, and provide a large range of high-performance solar electric systems across the USA, for domestic and business functions.
It is also worthwhile to discuss that NASA also has used SunPower’s cutting edge cell technology for their area programs.
Solar That’s Tough Enough for NASA is difficult Enough for Your Roof
But NASA is not the only one who has actually relied on SunPower items. Solar Impulse 2, a zero-fuel aircraft, set a world record for becoming the very first solar plane to fly all over the world, also utilizes SunPower solar cells.
There are lots of case studies out there using SunPower products, from schools, industries, and house owners, saving millions $$ in the process of going solar.
SunPower has recently decided to transform its manufacturing division into a brand-new company called Maxeon Solar, while SunPower will focus solely on the consumer and service side, installing photovoltaic panels.
The department began 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 enhance 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 during a November 11 teleconference.
Maxeon Solar will handle production and technological innovation, giving SunPower the capability to focus entirely on broadening its market share versus its competitors, such as Canadian Solar.
Resolving The Problem Of Solar Energy Consumption

SunPower is participated in the production and sale of solar panels, and they use a vast array of product choices.
Solar panels are alternative sources of energy. They are comprised of solar batteries that transform sunlight (and not only light) into electricity.
A total set consisting of solar panels, controllers, inverters, and batteries is called a Solar Power Plant. All this can be purchased from the company.
Moreover, they provide a guarantee for 25 years, unlike others who supply only 10 years. Also, when buying from them, they will bring and install batteries and everything you require totally free.

Products That SunPower Offers
SunPower makes a number of products, all related to solar power, like solar panels, complete systems, solar cells, total roof-integrated planetary systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower offers four series of solar panels. They are enhanced for different applications:
A-Series
Do you want to maximize your lifetime savings? Then SunPower A-Series panels is for you. A-Series delivers the most effective cell and greatest wattage panels you can put on your roofing system.
SunPower presented the world’s first 400-watt solar panel, which suggests you can have more power than ever before in a small space with fewer panels on your roofing system.
A photovoltaic panel is just 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 sized areas, with fewer panels. In this manner you can expand energy production simply by utilizing additional roofing space to include more panels later if you want.
They likewise deliver the greatest efficiency available in a property photovoltaic panel today, at a record-breaking 22.8%.
That indicates property owners get more electrical energy, more flexibility, more assurance, and lower electrical energy expenses.
E-Series
SunPower E-Series provide 36% more power per panel than conventional panels. Simply put, they transform more sunlight into electricity
E-Series are constructed with Maxeon solar batteries, delivering up to 20% efficiency and can be found in 320W, 327W, or 435W options.
P-Series
SunPower P-Series are built with an ingenious shingled design solar batteries that removes a number of the dependability difficulties of standard front contact panels.
P-Series panels offer 7% greater panel effectiveness and as much as 19 %more energy over the very first 25 years of operation.
However that is not all: SunPower Performance Series( P-Series) panels were named as a top entertainer in all those 5 dependability tests conducted by DNV GL, the world’s largest resource of independent energy professionals 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 been in solar power company for more than 35 years. The business was founded in 1985. Ever since, SunPower has actually been improving photovoltaic panels for domestic and business market. In this industry and numerous others, there are a lot of business that go and come.
Given that the financial investment in solar panels is significant, you better trust on a company that has actually proved to be here for several years.
Effectiveness
One of the most crucial factors in recording solar power is the effectiveness ranking of a panel. Not all photovoltaic panels are the same. A greater effectiveness score implies less panels to capture the exact same quantity of energy.
SunPower uses an market leading 22.8% efficiency score, which is around 60-70% higher than the competition.
Durability
Solar panels are a considerable financial investment for both, property owners and business services. So, they require to understand that they will last. SunPower panels exceeded competitors in reliability, energy production, deterioration rates, and shading effect.
SunPower panels are developed with resilient covers to remove UV degradation, copper foundations for additional strength, and they provide a single 25-year service warranty that covers the whole panel and all its elements.
Environmentally Safe
SunPower photovoltaic panels are eco-friendly. Anyone who is not indifferent to the health of the world, of course, will consider his duty to buy safe energy sources. Many individuals stop at wind turbines, the problem with them is they discharge special noises; photovoltaic panels are quiet.
Other individuals select any solar panels that are out there in the market. However, the scenario here resembles that of electrical cars: the batteries are eco-friendly, but they utilize toxic hazardous substances in the process of their production of batteries, power plants, conductors, etc. As a consequence, they end up contaminating the environment.
Sustainability
SunPower has actually long been the industry leader in sustainability and uses a complete closed loop sustainability method. Their philosophy is to drive sustainable service practices at every stage of the product life process and beyond.
