Are you tired of paying huge electrical energy expenses month after month? Going solar is your best option for big savings, and now, thanks to SunPower, it is more affordable 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 purchase
- Evaluations from real clients
Let’s get going…





SunPower is an American energy company established by Richard Swanson & Richard Crane in 1985. It began as EOS Electric Power. In 1988 it was relabelled SunPower. In 1990 the business got funding to begin producing solar batteries. In 1992 started shipping them to customers.
What Is SunPower?
SunPower is understood to design, manufacture, and deliver a wide variety of high-performance solar electric systems across the USA, for business and residential purposes.
It is likewise worthwhile to point out that NASA also has actually used SunPower’s advanced cell technology for their space programs.
Solar That’s Tough Enough for NASA is Tough 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 first solar aircraft to fly all over the world, likewise utilizes SunPower solar batteries.
There are a lot of case studies out there utilizing SunPower products, from house owners, schools, and industries, conserving millions $$ in the process of going solar.
SunPower has actually just recently decided to transform its production department into a new company called Maxeon Solar, while SunPower will focus specifically on the customer and service side, setting up photovoltaic panels.
The division started 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 blending 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 conference call.
Maxeon Solar will handle production and technological innovation, giving SunPower the ability to focus solely on expanding its market share versus its competitors, 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 provide a large range of product choices.
Photovoltaic panel are alternative sources of energy. They are made up of solar cells that convert sunshine (and not only light) into electrical power.
A complete set consisting of solar panels, inverters, controllers, and batteries is called a Solar Power Plant. All this can be purchased from the business.
Moreover, they offer an assurance for 25 years, unlike others who provide only 10 years. Likewise, when buying from them, they will bring and set up batteries and whatever you require free of charge.

Products That SunPower Offers
SunPower manufactures several items, all related to solar energy, like photovoltaic panels, total systems, solar cells, complete 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 optimize your life time savings? Then SunPower A-Series panels is for you. A-Series provides the most effective cell and highest 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 less panels on your roof.
A solar panel is just as good as the cells inside. The A-Series panels use SunPower® Maxeon® Gen 5 solar batteries, which are 65% larger than previous generations. This implies
X-Series
SunPower X-Series solar panels deliver 44% more power per panel, resulting more power in smaller spaces, with fewer panels. In this manner you can expand energy production just by utilizing extra roof space to add more panels later on if you want.
They likewise provide the highest performance offered in a domestic solar panel today, at a record-breaking 22.8%.
That means property owners get more electricity, more flexibility, more assurance, and lower electrical power costs.
E-Series
SunPower E-Series deliver 36% more power per panel than conventional panels. Put simply, they transform more sunlight into electrical power
E-Series are built with Maxeon solar cells, delivering up to 20% performance and is available in 327W, 320w, or 435w choices.
P-Series
SunPower P-Series are constructed with an innovative shingled style solar batteries that removes much of the reliability difficulties of conventional front contact panels.
P-Series panels provide 7% higher panel effectiveness and as much as 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 carried out by DNV GL, the world’s largest resource of independent energy experts 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 numerous benefits of going solar by using SunPower items:
Experience
SunPower has actually remained in solar power company for more than 35 years. The company was founded in 1985. Ever since, SunPower has actually been perfecting photovoltaic panels for commercial and residential market. In this market and lots of others, there are a lot of business that reoccur.
Since the financial investment in photovoltaic panels is considerable, you much better trust on a business that has shown to be here for many years.
Efficiency
Among the most important factors in capturing solar power is the performance rating of a panel. Not all photovoltaic panels are the same. A higher efficiency score means less panels to record the very same quantity of energy.
SunPower uses an market leading 22.8% performance ranking, which is around 60-70% higher than the competitors.
Toughness
Photovoltaic panel are a substantial investment for both, property owners and industrial companies. So, they need to know that they will last. SunPower panels exceeded competitors in reliability, energy production, destruction rates, and shading effect.
SunPower panels are built with durable covers to remove UV degradation, copper foundations for additional 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 eco-friendly. Any person who is not indifferent to the health of the planet, naturally, will consider his duty to buy harmless energy sources. Many people stop at wind turbines, the issue with them is they discharge unique sounds; photovoltaic panels are quiet.
Other individuals pick any solar panels that are out there in the market. However, the situation here resembles that of electric vehicles: the batteries are environmentally friendly, but they utilize toxic hazardous compounds in the process of their production of batteries, power plants, conductors, etc. As a consequence, they end up contaminating the environment.
