Are you tired of paying huge electrical power bills month after month? Going solar is your best option for big cost savings, and now, thanks to SunPower, it is less expensive and easier than ever before.
This is what you are about to learn:
- What is SunPower
- The benefits and drawbacks of SunPower and going solar
- Where to buy
- Reviews from actual customers
Let’s get going…





SunPower is an American energy business established by Richard Swanson & Richard Crane in 1985. It began as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the company received moneying to start producing solar cells. In 1992 began delivering them to clients.
What Is SunPower?
SunPower is known to style, manufacture, and provide a wide variety of high-performance solar electrical systems throughout the USA, for residential and business functions.
It is likewise rewarding to point out that NASA likewise has actually used SunPower’s advanced cell innovation 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 actually trusted SunPower products. Solar Impulse 2, a zero-fuel plane, set a world record for ending up being the very first solar airplane to fly around the globe, also uses SunPower solar cells.
There are a lot of case studies out there using SunPower items, from house owners, schools, and markets, conserving millions $$ in the process of going solar.
SunPower has actually recently decided to transform its production department into a brand-new business called Maxeon Solar, while SunPower will focus specifically on the consumer and service side, installing photovoltaic panels.
The department began with a $298 million 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 enhance 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 said during a November 11 conference call.
Maxeon Solar will handle production and technological development, offering SunPower the capability to focus entirely on broadening its market share against its competitors, such as Canadian Solar.
Resolving The Problem Of Solar Energy Consumption

SunPower is participated in the production and sale of solar panels, and they use a large range of product choices.
Solar panels are alternative sources of energy. They are made up of solar batteries that transform sunshine (and not only light) into electrical energy.
A total set consisting of photovoltaic panels, batteries, inverters, and controllers is called a Solar Power Plant. All this can be purchased from the business.
Moreover, they offer a warranty for 25 years, unlike others who supply just 10 years. Likewise, when purchasing from them, they will bring and install batteries and everything you require for free.

Products That SunPower Offers
SunPower produces several items, all related to solar power, like photovoltaic panels, complete systems, solar cells, complete roof-integrated planetary systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower uses four series of solar panels. They are optimized for various applications:
A-Series
Do you wish to optimize your life time 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 roof.
SunPower introduced the world’s very first 400-watt photovoltaic panel, which means you can have more power than ever before in a little space with fewer panels on your roof.
A photovoltaic 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 indicates
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 broaden energy production merely by utilizing extra roof area to add more panels later on if you desire.
They likewise provide the greatest efficiency offered in a domestic solar panel today, at a record-breaking 22.8%.
That suggests homeowners get more electricity, more versatility, more peace of mind, and lower electrical energy costs.
E-Series
SunPower E-Series provide 36% more power per panel than traditional panels. Simply put, they convert more sunshine into electrical power
E-Series are built with Maxeon solar batteries, delivering up to 20% effectiveness and is available in 320W, 327W, or 435W options.
P-Series
SunPower P-Series are constructed with an innovative shingled style solar cells that gets rid of many of the reliability difficulties of traditional front contact panels.
P-Series panels offer 7% greater 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 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 accreditation body. Those tests include:
- Thermal cycling
- Damp heat
- Humidity-freeze
- Dynamic mechanical load
- Potential induced degradation
Benefits Of SunPower Solar Panels
There are lots of benefits of going solar by utilizing SunPower items:
Experience
SunPower has been in solar energy company for more than 35 years. The company was founded in 1985. Since then, SunPower has actually been perfecting photovoltaic panels for business and domestic market. In this industry and lots of others, there are lots of companies that reoccur.
Given that the financial investment in photovoltaic panels is significant, you better trust on a business that has actually shown to be here for many years.
Effectiveness
Among the most essential consider capturing solar energy is the efficiency ranking of a panel. Not all photovoltaic panels are the same. A higher effectiveness rating means less panels to record the very same quantity of energy.
SunPower uses an market leading 22.8% effectiveness rating, which is roughly 60-70% higher than the competition.
Toughness
Photovoltaic panel are a considerable investment for both, house owners and business companies. So, they require to know that they will last. SunPower panels surpassed competitors in dependability, energy production, deterioration rates, and shading impact.
SunPower panels are constructed with durable covers to eliminate 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 photovoltaic panels are eco-friendly. Any person who is not indifferent to the health of the world, of course, will consider his task to buy safe energy sources. Many individuals stop at wind turbines, the issue with them is they give off unique noises; photovoltaic panels are quiet.
Other individuals choose any photovoltaic panels that are out there in the market. However, the scenario here is similar to that of electric vehicles: the batteries are environmentally friendly, but they utilize poisonous hazardous compounds in the process 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 complete closed loop sustainability strategy. Their approach is to drive sustainable organization practices at every phase of the product life process and beyond.
