Are you tired of paying big electrical energy expenses month after month? Going solar is your best bet for huge savings, and now, thanks to SunPower, it is cheaper and simpler than ever before.
This is what you are about to discover:
- What is SunPower
- The cons and pros of SunPower and going solar
- Where to buy
- Evaluations from actual clients
Let’s begin…





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 business received moneying to begin making solar cells. In 1992 began delivering them to clients.
What Is SunPower?
SunPower is understood to design, manufacture, and deliver a wide variety of high-performance solar electric systems across the USA, for industrial and property functions.
It is also worthwhile to discuss that NASA also has used SunPower’s advanced cell technology 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 actually trusted SunPower products. Solar Impulse 2, a zero-fuel plane, set a world record for becoming the very first solar plane to fly worldwide, likewise utilizes SunPower solar batteries.
There are lots of case studies out there using SunPower items, from markets, homeowners, and schools, saving millions $$ in the process of going solar.
SunPower has just recently decided to convert its manufacturing division into a new company called Maxeon Solar, while SunPower will focus exclusively on the customer and service side, installing photovoltaic panels.
The department 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 goal 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 development, offering SunPower the capability to focus entirely on expanding its market share against its rivals, such as Canadian Solar.
Resolving The Problem Of Solar Energy Consumption

SunPower is engaged in the production and sale of solar panels, and they provide a wide variety of item choices.
Photovoltaic panel are alternative sources of energy. They are made up of solar cells that convert sunlight (and not only light) into electrical power.
A complete set consisting of photovoltaic panels, batteries, controllers, and inverters is called a Solar Power Plant. All this can be bought from the company.
Furthermore, they give a guarantee for 25 years, unlike others who provide only 10 years. Likewise, when buying from them, they will bring and install batteries and whatever you need free of charge.

Products That SunPower Offers
SunPower produces several products, all related to solar energy, like photovoltaic panels, complete systems, solar cells, complete roof-integrated solar systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower offers 4 series of solar panels. They are enhanced for various applications:
A-Series
Do you want to maximize your life time 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 roofing system.
SunPower presented the world’s first 400-watt solar panel, which indicates you can have more power than ever before in a little space with less panels on your roof.
A solar panel is just 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 indicates
X-Series
SunPower X-Series photovoltaic panels deliver 44% more power per panel, resulting more power in smaller sized spaces, with less panels. In this manner you can expand energy production just by utilizing extra roofing system space to include more panels later on if you desire.
They also deliver the highest effectiveness readily available in a domestic photovoltaic panel today, at a record-breaking 22.8%.
That indicates property owners get more electricity, more flexibility, more assurance, and lower electrical energy bills.
E-Series
SunPower E-Series provide 36% more power per panel than traditional panels. Put simply, they transform more sunlight into electrical power
E-Series are developed with Maxeon solar batteries, delivering up to 20% performance and comes in 327W, 320w, or 435w options.
P-Series
SunPower P-Series are built with an innovative shingled style solar cells that gets rid of many of the dependability difficulties of conventional front contact panels.
P-Series panels offer 7% greater panel effectiveness 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 leading performer in all those 5 reliability tests performed 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 benefits of going solar by using SunPower items:
Experience
SunPower has remained in solar power company for more than 35 years. The company was founded in 1985. Since then, SunPower has actually been refining photovoltaic panels for commercial and property market. In this industry and numerous others, there are lots of companies that come and go.
Given that the investment in photovoltaic panels is substantial, you better trust on a company that has shown to be here for many years.
Efficiency
Among the most crucial factors in capturing solar energy is the performance rating of a panel. Not all photovoltaic panels are the same. A greater performance ranking suggests less panels to record the exact same quantity of energy.
SunPower offers an market leading 22.8% effectiveness score, which is around 60-70% higher than the competitors.
Durability
Photovoltaic panel are a significant financial investment for both, property owners and industrial services. So, they need to know that they will last. SunPower panels outshined competitors in reliability, energy production, degradation rates, and shading effect.
SunPower panels are constructed with durable covers to remove UV degradation, copper foundations for added strength, and they offer a single 25-year service warranty that covers the entire panel and all its parts.
Environmentally Safe
SunPower photovoltaic panels are environmentally friendly. Any person who is not indifferent to the health of the world, obviously, will consider his task to purchase harmless energy sources. Lots of people stop at wind turbines, the issue with them is they discharge unique noises; solar panels are quiet.
Other individuals pick any photovoltaic panels that are out there in the market. However, the scenario here resembles that of electric cars: the batteries are eco-friendly, however they use toxic harmful substances while doing so of their production of batteries, power plants, conductors, and so on. As a consequence, they wind up polluting the environment.
Sustainability
SunPower has actually long been the industry leader in sustainability and uses a complete closed loop sustainability technique. Their viewpoint is to drive sustainable business practices at every stage of the product life process and beyond.
This technique led the way for SunPower to become the winner of pv publication’s first annual sustainability award.
Service Warranty

SunPower uses an unprecedented 25 years total confidence guarantee. They cover whatever on your Roof. They will fix, change or repay defective parts, and you get the market’s best power guarantee. Each part goes through weeks of aging, quality, and testing control prior to assembly and final inspection. After all, a much better item indicates a much better service warranty.
Keep in mind: with conventional solar, even a small concern can end up being a big headache, separate warranties for each part (racking, panel, monitoring, inverter), unpredictable service charge (installation of replacement not included, shipping not consisted of), low power output, lots of documents, numerous suppliers. It suffices to make your head spin.
