SunPower X21-335-Blk Review
Are you tired of paying substantial electricity bills month after month? Going solar is your best option for big savings, and now, thanks to SunPower, it is cheaper and much easier than ever before.
This is what you will find out:
- What is SunPower
- The cons and pros of SunPower and going solar
- Where to buy
- Reviews from real consumers
Let’s get started…





SunPower is an American energy company established by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the company received funding to begin producing solar batteries. In 1992 started delivering them to consumers.
What Is SunPower?
SunPower is understood to design, manufacture, and deliver a vast array of high-performance solar electric systems across the USA, for business and property functions.
It is also rewarding to point out that NASA also has used SunPower’s modern 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 relied on SunPower items. Solar Impulse 2, a zero-fuel plane, set a world record for becoming the very first solar aircraft to fly all over the world, also utilizes SunPower solar batteries.
There are a lot of case studies out there utilizing SunPower products, from schools, house owners, and markets, saving millions $$ in the process of going solar.
SunPower has recently chosen to transform its production division into a new business called Maxeon Solar, while SunPower will focus exclusively on the consumer 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 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 said during a November 11 teleconference.
Maxeon Solar will handle production and technological development, offering SunPower the ability to focus exclusively on broadening its market share against its competitors, such as Canadian Solar.
Solving The Problem Of Solar Energy Consumption

SunPower is engaged in the production and sale of solar panels, and they use a wide variety of item selections.
Photovoltaic panel are alternative sources of energy. They are comprised of solar batteries that convert sunlight (and not only light) into electricity.
A total set consisting of photovoltaic panels, controllers, inverters, and batteries is called a Solar Power Plant. All this can be bought from the business.
Additionally, they give a guarantee for 25 years, unlike others who supply just 10 years. Also, when purchasing from them, they will bring and install batteries and everything you need totally free.

Products That SunPower Offers
SunPower manufactures numerous items, 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 4 series of solar panels. They are enhanced for different applications:
A-Series
Do you wish to optimize your life time cost savings? Then SunPower A-Series panels is for you. A-Series delivers the most effective cell and greatest wattage panels you can place on your roofing system.
SunPower presented the world’s very first 400-watt solar panel, which indicates you can have more power than ever before in a little space with fewer panels on your roofing system.
A photovoltaic panel is only as good as the cells inside. The A-Series panels use SunPower® Maxeon® Gen 5 solar cells, which are 65% larger than previous generations. This implies
X-Series
SunPower X-Series photovoltaic panels deliver 44% more power per panel, resulting more power in smaller spaces, with fewer panels. By doing this you can expand energy production merely by using extra roofing system area to include more panels later on if you desire.
They likewise provide the greatest performance readily available in a residential solar panel today, at a record-breaking 22.8%.
That implies property owners get more electricity, more versatility, more assurance, and lower electrical power costs.
E-Series
SunPower E-Series provide 36% more power per panel than traditional panels. Simply put, they transform more sunshine into electrical power
E-Series are developed with Maxeon solar cells, delivering up to 20% performance and is available in 320W, 435w, or 327w alternatives.
P-Series
SunPower P-Series are built with an innovative shingled design solar cells that eliminates much of the dependability difficulties of standard front contact panels.
P-Series panels offer 7% greater panel efficiency 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 leading entertainer in all those five reliability tests carried out by DNV GL, the world’s largest resource of independent energy specialists 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 lots of advantages of going solar by utilizing SunPower products:
Experience
SunPower has actually remained in solar energy service for more than 35 years. The business was founded in 1985. Since then, SunPower has actually been improving photovoltaic panels for commercial and domestic market. In this market and many others, there are lots of companies that reoccur.
Considering that the investment in solar panels is significant, you much better trust on a business that has shown to be here for many years.
Effectiveness
Among the most important consider recording solar energy is the effectiveness ranking of a panel. Not all photovoltaic panels are the same. A higher effectiveness score means less panels to record the same quantity of energy.
SunPower uses an market leading 22.8% effectiveness score, which is roughly 60-70% higher than the competition.
Resilience
Solar panels are a considerable financial investment for both, property owners and business organizations. So, they need to know that they will last. SunPower panels exceeded rivals in dependability, energy production, degradation rates, and shading impact.
SunPower panels are built with long lasting covers to remove UV destruction, copper foundations for added strength, and they use a single 25-year guarantee that covers the whole panel and all its elements.
Environmentally Safe
SunPower solar panels are environmentally friendly. Anybody who is not indifferent to the health of the world, of course, will consider his task to purchase safe energy sources. Lots of people stop at wind turbines, the issue with them is they emit special noises; solar panels are quiet.
Other people select any solar panels that are out there in the market. However, the situation here is similar to that of electrical vehicles: the batteries are eco-friendly, but they utilize toxic damaging compounds 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 market leader in sustainability and utilizes a full closed loop sustainability method. Their viewpoint is to drive sustainable company practices at every stage of the item life process and beyond.
