Are you tired of paying big electricity bills month after month? Going solar is your best choice for huge savings, and now, thanks to SunPower, it is cheaper and simpler than ever before.
This is what you will discover:
- What is SunPower
- The benefits and drawbacks of SunPower and going solar
- Where to buy
- Reviews from real consumers
Let’s start…





SunPower is an American energy company founded by Richard Swanson & Richard Crane in 1985. It began as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the business received funding to begin producing solar cells. In 1992 began delivering them to consumers.
What Is SunPower?
SunPower is understood to design, manufacture, and provide a wide range of high-performance solar electrical systems across the USA, for residential and commercial purposes.
It is also rewarding to point out that NASA also has actually utilized SunPower’s cutting edge cell innovation for their area programs.
Solar That’s Tough Enough for NASA is difficult Enough for Your Roof
However NASA is not the only one who has relied on SunPower products. Solar Impulse 2, a zero-fuel plane, set a world record for becoming the very first solar airplane to fly all over the world, likewise utilizes SunPower solar cells.
There are lots of case studies out there using SunPower products, from house owners, markets, and schools, conserving millions $$ in the process of going solar.
SunPower has recently chosen to convert its manufacturing division into a brand-new company called Maxeon Solar, while SunPower will focus solely on the consumer and service side, installing solar panels.
The department started with a $298 million financial investment by SunPower’s partner and the world’s leading supplier 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 business without blending 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 teleconference.
Maxeon Solar will take on production and technological innovation, offering SunPower the capability to focus entirely on expanding its market share versus its rivals, 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 provide a vast array of item selections.
Photovoltaic panel are alternative sources of energy. They are made up of solar cells that convert sunshine (and not just light) into electricity.
A complete set consisting of solar panels, inverters, batteries, and controllers is called a Solar Power Plant. All this can be bought from the company.
Moreover, they provide a guarantee for 25 years, unlike others who supply just 10 years. Likewise, when buying from them, they will bring and set up batteries and whatever you require totally free.

Products That SunPower Offers
SunPower manufactures a number of products, all related to solar energy, like photovoltaic 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 enhanced for different applications:
A-Series
Do you want to maximize your lifetime cost savings? Then SunPower A-Series panels is for you. A-Series delivers the most powerful cell and greatest wattage panels you can put on your roof.
SunPower introduced the world’s very first 400-watt photovoltaic panel, which implies you can have more power than ever before in a small area with fewer panels on your roofing.
A solar 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 suggests
X-Series
SunPower X-Series solar panels provide 44% more power per panel, resulting more power in smaller areas, with fewer panels. In this manner you can broaden energy production simply by using extra roofing area to add more panels later on if you desire.
They likewise provide the highest efficiency offered in a residential photovoltaic panel today, at a record-breaking 22.8%.
That indicates house owners get more electrical energy, more flexibility, more peace of mind, and lower electrical power expenses.
E-Series
SunPower E-Series provide 36% more power per panel than conventional panels. Put simply, they convert more sunlight into electrical energy
E-Series are constructed with Maxeon solar cells, delivering up to 20% effectiveness and comes in 327W, 320w, or 435w alternatives.
P-Series
SunPower P-Series are developed with an innovative shingled design solar cells that gets rid of a lot of the reliability obstacles of conventional front contact panels.
P-Series panels provide 7% higher panel performance 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 called as a leading performer in all those 5 dependability tests carried out by DNV GL, the world’s largest resource of independent energy professionals and accreditation body. Those tests consist of:
- Thermal cycling
- Damp heat
- Humidity-freeze
- Dynamic mechanical load
- Potential induced degradation
Benefits Of SunPower Solar Panels
There are many benefits of going solar by utilizing SunPower items:
Experience
SunPower has actually 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 property and industrial market. In this industry and many others, there are plenty of business that go and come.
Considering that the investment in photovoltaic panels is considerable, you better trust on a company that has actually proved to be here for many years.
Efficiency
Among the most essential factors in recording solar energy is the effectiveness rating of a panel. Not all photovoltaic panels are the same. A greater performance ranking implies less panels to catch the same quantity of energy.
SunPower provides an market leading 22.8% effectiveness score, which is roughly 60-70% higher than the competition.
Resilience
Solar panels are a significant investment for both, property owners and commercial services. So, they need to know that they will last. SunPower panels surpassed rivals in reliability, energy production, destruction rates, and shading effect.
SunPower panels are developed with durable covers to eliminate UV destruction, copper foundations for additional strength, and they provide a single 25-year guarantee that covers the whole panel and all its components.
Environmentally Safe
SunPower photovoltaic panels are eco-friendly. Any person who is not indifferent to the health of the planet, obviously, will consider his responsibility to purchase harmless energy sources. Many individuals stop at wind turbines, the issue with them is they give off unique noises; solar panels are quiet.
Other people choose any photovoltaic panels that are out there in the market. However, the scenario here is similar to that of electrical cars: the batteries are environmentally friendly, however they use poisonous damaging substances at the same time of their production of batteries, power plants, conductors, etc. As a consequence, they end up polluting the environment.
Sustainability
SunPower has actually long been the industry leader in sustainability and utilizes a full closed loop sustainability method. Their philosophy is to drive sustainable company practices at every phase of the product life process and beyond.
