Sunpower 400W Modules
Are you tired of paying huge electrical energy costs month after month? Going solar is your best bet for huge savings, and now, thanks to SunPower, it is less expensive and simpler than ever before.
This is what you are about to find out:
- What is SunPower
- The benefits and drawbacks of SunPower and going solar
- Where to buy
- Evaluations from actual consumers
Let’s start…





SunPower is an American energy company founded by Richard Swanson & Richard Crane in 1985. It started as EOS Electric Power. In 1988 it was renamed SunPower. In 1990 the business got funding to begin manufacturing solar batteries. In 1992 began shipping them to clients.
What Is SunPower?
SunPower is known to design, manufacture, and provide a large range of high-performance solar electric systems throughout the USA, for residential and industrial purposes.
It is likewise rewarding to mention that NASA also has used SunPower’s cutting edge cell technology for their space 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 ending up being the first solar aircraft to fly worldwide, likewise uses SunPower solar batteries.
There are plenty of case studies out there using SunPower items, from property owners, industries, and schools, conserving millions $$ in the process of going solar.
SunPower has just recently decided to transform its manufacturing department into a brand-new business called Maxeon Solar, while SunPower will focus solely on the consumer and service side, installing photovoltaic panels.
The department started 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 objective 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 stated throughout a November 11 teleconference.
Maxeon Solar will take on production and technological development, offering SunPower the capability to focus exclusively on broadening its market share against its competitors, such as Canadian Solar.
Solving The Problem Of Solar Energy Consumption

SunPower is participated in the production and sale of solar panels, and they provide a wide variety of item choices.
Solar panels are alternative sources of energy. They are comprised of solar batteries that convert sunlight (and not just light) into electrical power.
A total set consisting of photovoltaic panels, inverters, batteries, and controllers is called a Solar Power Plant. All this can be purchased from the business.
Furthermore, they provide a warranty for 25 years, unlike others who supply just 10 years. Likewise, when purchasing from them, they will bring and install batteries and whatever you require free of charge.

Products That SunPower Offers
SunPower makes a number of items, all related to solar power, like photovoltaic panels, total systems, solar cells, complete roof-integrated planetary systems, and solar battery storage.
Let’s dig in …
SunPower Solar Panels
SunPower offers four series of photovoltaic panels. They are optimized for different applications:
A-Series
Do you wish to maximize your life time cost savings? Then SunPower A-Series panels is for you. A-Series delivers the most powerful cell and highest wattage panels you can put on your roofing system.
SunPower presented the world’s first 400-watt photovoltaic panel, which indicates you can have more power than ever before in a small space with less 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 indicates
X-Series
SunPower X-Series photovoltaic panels deliver 44% more power per panel, resulting more power in smaller sized areas, with fewer panels. By doing this you can expand energy production just by utilizing additional roofing system space to include more panels later if you desire.
They likewise deliver the highest efficiency readily available in a property solar panel today, at a record-breaking 22.8%.
That implies property owners get more electricity, more versatility, more assurance, and lower electrical power bills.
E-Series
SunPower E-Series deliver 36% more power per panel than traditional panels. Basically, they convert more sunlight into electrical energy
E-Series are constructed with Maxeon solar cells, delivering up to 20% effectiveness and can be found in 435W, 327w, or 320w choices.
P-Series
SunPower P-Series are constructed with an ingenious shingled design solar cells that removes many of the dependability difficulties of conventional front contact panels.
P-Series panels offer 7% higher panel performance and approximately 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 performer in all those five dependability tests conducted 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 many advantages of going solar by utilizing SunPower products:
Experience
SunPower has actually remained in solar energy company for more than 35 years. The business was founded in 1985. Ever since, SunPower has been improving solar panels for property and industrial market. In this industry and many others, there are a lot of business that reoccur.
Given that the investment in solar panels is substantial, you better trust on a company that has actually shown to be here for several years.
Effectiveness
Among the most essential consider recording solar power is the performance rating of a panel. Not all photovoltaic panels are the same. A greater performance rating means less panels to capture the same amount of energy.
SunPower provides an market leading 22.8% efficiency rating, which is approximately 60-70% higher than the competition.
Sturdiness
Solar panels are a considerable investment for both, house owners and business services. So, they need to understand that they will last. SunPower panels outperformed competitors in reliability, energy production, deterioration rates, and shading impact.
SunPower panels are constructed with resilient covers to remove UV degradation, copper foundations for extra strength, and they provide a single 25-year service warranty that covers the entire panel and all its components.
Environmentally Safe
SunPower solar panels are environmentally friendly. Anyone who is not indifferent to the health of the planet, naturally, will consider his responsibility to purchase harmless energy sources. Lots of people stop at wind turbines, the problem with them is they emit unique noises; solar panels are quiet.
Other people select any photovoltaic panels that are out there in the market. However, the scenario here resembles that of electric lorries: the batteries are environmentally friendly, however they utilize poisonous hazardous substances while doing so 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 uses a full closed loop sustainability strategy. Their approach is to drive sustainable service practices at every phase of the product life cycle and beyond.
This strategy led the way for SunPower to end up being the winner of pv magazine’s very first yearly sustainability award.
Service Warranty

SunPower uses an unprecedented 25 years total self-confidence service warranty. They cover whatever on your Roof. They will fix, replace or compensate faulty parts, and you get the market’s finest power warranty. Each part goes through weeks of screening, quality, and aging control before assembly and final assessment. After all, a much better product suggests a better warranty.
Keep in mind: with conventional solar, even a small issue can end up being a big headache, different warranties for each part (racking, panel, tracking, inverter), unpredictable service charge (installation of replacement not consisted of, delivering not consisted of), low power output, tons of documents, several suppliers. It suffices to make your head spin.
