Sunpower E-Series 327
Are you tired of paying huge electrical power bills month after month? Going solar is your best choice for huge cost savings, and now, thanks to SunPower, it is cheaper and easier than ever before.
This is what you will find out:
- What is SunPower
- The pros and cons of SunPower and going solar
- Where to buy
- Reviews from real consumers
Let’s begin…





SunPower is an American energy company 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 start manufacturing solar batteries. In 1992 began shipping them to customers.
What Is SunPower?
SunPower is understood to style, manufacture, and provide a vast array of high-performance solar electrical systems throughout the USA, for property and commercial functions.
It is also rewarding to discuss that NASA also has actually used SunPower’s state-of-the-art cell innovation for their area programs.
Solar That’s Tough Enough for NASA is Tough Enough for Your Roof
But NASA is not the only one who has actually relied on SunPower products. Solar Impulse 2, a zero-fuel aircraft, set a world record for ending up being the first solar aircraft to fly around the world, likewise uses SunPower solar cells.
There are lots of case studies out there utilizing SunPower items, from house owners, markets, and schools, conserving millions $$ in the process of going solar.
SunPower has just recently decided to convert its manufacturing division into a new business called Maxeon Solar, while SunPower will focus solely on the customer and service side, setting up photovoltaic panels.
The department began 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 goal is to optimize the core operations of the two companies 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 ability to focus solely on expanding its market share versus its competitors, such as Canadian Solar.
Fixing The Problem Of Solar Energy Consumption

SunPower is engaged in the production and sale of photovoltaic panels, and they offer a wide variety of item selections.
Photovoltaic panel are alternative sources of energy. They are comprised of solar cells that convert sunlight (and not only light) into electrical power.
A complete set consisting of photovoltaic panels, inverters, batteries, and controllers is called a Solar Power Plant. All this can be bought from the business.
Furthermore, they offer a warranty for 25 years, unlike others who offer only 10 years. Also, 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 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 optimized for different applications:
A-Series
Do you want to maximize 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 put on your roofing system.
SunPower introduced the world’s first 400-watt photovoltaic panel, which means you can have more power than ever before in a little space with fewer panels on your roofing.
A photovoltaic panel is just 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 suggests
X-Series
SunPower X-Series solar panels deliver 44% more power per panel, resulting more power in smaller sized spaces, with fewer panels. This way you can expand energy production simply by utilizing extra roofing area to add more panels later on if you desire.
These state of the art panels convert more sunlight into electrical energy, producing 75% more energy per square foot over the very first 25 years.
They also deliver the highest efficiency available in a domestic photovoltaic panel today, at a record-breaking 22.8%.
That indicates property owners get more electrical power, more flexibility, more peace of mind, and lower electrical energy costs.
E-Series
SunPower E-Series deliver 36% more power per panel than conventional panels. Simply put, they transform more sunlight into electrical energy
E-Series are built with Maxeon solar batteries, delivering up to 20% effectiveness and comes in 327W, 435w, or 320w options.
P-Series
SunPower P-Series are built with an innovative shingled style solar cells that gets rid of much of the dependability challenges of standard front contact panels.
P-Series panels provide 7% higher 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 named as a leading performer in all those five reliability tests performed by DNV GL, the world’s largest resource of independent energy specialists and certification body. Those tests consist of:
- Thermal cycling
- Damp heat
- Humidity-freeze
- Dynamic mechanical load
- Potential induced degradation
Benefits Of SunPower Solar Panels
There are lots of advantages of going solar by utilizing SunPower items:
Experience
SunPower has been in solar energy business for more than 35 years. The business was founded in 1985. Ever since, SunPower has actually been perfecting solar panels for domestic and industrial market. In this market and numerous others, there are a lot of companies that go and come.
Considering that the investment in solar panels is considerable, you much better trust on a business that has proved to be here for several years.
Effectiveness
Among the most important factors in capturing solar power is the effectiveness rating of a panel. Not all photovoltaic panels are the same. A greater effectiveness score implies less panels to record the exact same quantity of energy.
SunPower uses an industry leading 22.8% efficiency rating, which is roughly 60-70% higher than the competitors.
Durability
Photovoltaic panel are a significant investment for both, homeowners and business organizations. So, they need to know that they will last. SunPower panels surpassed competitors in dependability, energy production, degradation rates, and shading impact.
SunPower panels are developed with long lasting covers to get rid of UV deterioration, copper structures for added strength, and they use a single 25-year service warranty that covers the entire panel and all its components.
Ecologically Safe
SunPower solar panels are eco-friendly. Anyone who is not indifferent to the health of the planet, of course, will consider his task to purchase safe energy sources. Many people stop at wind turbines, the problem with them is they discharge special sounds; solar panels are quiet.
Other individuals select any photovoltaic panels that are out there in the market. Nevertheless, the scenario here resembles that of electrical cars: the batteries are environmentally friendly, but they utilize toxic harmful compounds while doing so of their production of batteries, power plants, conductors, etc. As a consequence, they wind up contaminating the environment.
Sustainability
SunPower has actually long been the market leader in sustainability and utilizes a full closed loop sustainability method. Their philosophy is to drive sustainable service practices at every stage of the item life process and beyond.

They will fix, replace or reimburse defective parts, and you get the industry’s finest power guarantee. Each part goes through weeks of aging, quality, and testing control prior to assembly and final examination. After all, a much better item indicates a better warranty.
Keep in mind:
With conventional solar, even a little concern can end up being a huge headache, separate guarantees for each part (racking, panel, monitoring, inverter), unforeseeable service charge (installation of replacement not included, delivering not included), low power output, lots of documentation, numerous providers. It is enough to make your head spin.
