Are you tired of paying big electrical power costs month after month? Going solar is your best option for huge savings, and now, thanks to SunPower, it is cheaper and simpler than ever before.
This is what you will find out:
- What is SunPower
- The advantages and disadvantages of SunPower and going solar
- Where to buy
- Evaluations from real consumers
Let’s begin…





SunPower is an American energy business founded by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was relabelled SunPower. In 1990 the business received funding to start manufacturing solar batteries. In 1992 began delivering them to clients.
What Is SunPower?
SunPower is understood to design, manufacture, and deliver a wide range of high-performance solar electrical systems throughout the USA, for industrial and domestic functions.
It is likewise rewarding to point out that NASA also has actually utilized SunPower’s modern cell innovation 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 airplane, set a world record for becoming the first solar aircraft to fly worldwide, likewise utilizes SunPower solar cells.
There are a lot of case studies out there using SunPower products, from industries, house owners, and schools, saving millions $$ in the process of going solar.
SunPower has recently chosen to convert its manufacturing department into a brand-new company called Maxeon Solar, while SunPower will focus solely on the customer and service side, setting up photovoltaic 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 business 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 development, offering SunPower the capability to focus solely on expanding its market share against its rivals, such as Canadian Solar.
Solving The Problem Of Solar Energy Consumption

SunPower is taken part in the production and sale of solar panels, and they use a wide range 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 bought from the company.
Additionally, they offer an assurance for 25 years, unlike others who supply just 10 years. Likewise, when buying from them, they will bring and set up batteries and everything you require totally free.

Products That SunPower Offers
SunPower produces a number of items, all related to solar power, like photovoltaic panels, total systems, solar cells, complete roof-integrated planetary systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower uses 4 series of solar panels. They are enhanced for various applications:
A-Series
Do you wish to maximize your lifetime cost savings? Then SunPower A-Series panels is for you. A-Series provides the most effective cell and greatest wattage panels you can put on your roof.
SunPower presented the world’s very first 400-watt photovoltaic panel, which suggests you can have more power than ever before in a small space with less 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 cells, 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 sized areas, with less panels. This way you can expand energy production merely by utilizing extra roofing system space to add more panels later on if you want.
They also deliver the greatest performance available in a domestic photovoltaic panel today, at a record-breaking 22.8%.
That suggests property owners get more electrical power, more versatility, more comfort, and lower electricity bills.
E-Series
SunPower E-Series provide 36% more power per panel than conventional panels. Basically, they convert more sunlight into electrical energy
E-Series are constructed with Maxeon solar cells, delivering up to 20% performance and comes in 435W, 327w, or 320w choices.
P-Series
SunPower P-Series are constructed with an ingenious shingled design solar batteries that removes much of the reliability obstacles of conventional front contact panels.
P-Series panels provide 7% greater panel efficiency and approximately 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 top entertainer in all those 5 reliability tests carried out by DNV GL, the world’s largest 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 many advantages of going solar by utilizing SunPower products:
Experience
SunPower has remained in solar power company for more than 35 years. The company was founded in 1985. Ever since, SunPower has actually been improving solar panels for residential and industrial market. In this industry and lots of others, there are a lot of business that go and come.
Given that the investment in photovoltaic panels is significant, you much better trust on a business that has shown to be here for several years.
Efficiency
One of the most essential factors in recording solar energy is the efficiency score of a panel. Not all photovoltaic panels are the same. A greater effectiveness ranking implies fewer panels to record the very same amount of energy.
SunPower provides an market leading 22.8% efficiency score, which is around 60-70% higher than the competition.
Resilience
Solar panels are a considerable financial investment for both, homeowners and business organizations. So, they require to know that they will last. SunPower panels outshined rivals in dependability, energy production, deterioration rates, and shading impact.
SunPower panels are constructed with long lasting covers to get rid of UV deterioration, copper structures for extra strength, and they use a single 25-year service warranty that covers the whole panel and all its parts.
Environmentally Safe
SunPower solar panels are environmentally friendly. Anybody who is not indifferent to the health of the planet, naturally, will consider his duty to purchase harmless energy sources. Many people stop at wind turbines, the problem with them is they produce special sounds; solar panels are quiet.
Other individuals choose any photovoltaic panels that are out there in the market. However, the circumstance here is similar to that of electric lorries: the batteries are eco-friendly, however they utilize toxic hazardous compounds while doing so of their production of batteries, power plants, conductors, and so on. As a consequence, they end up contaminating the environment.
