SunPower Solar Panels – USA

SunPower solar panels consistently deliver more energy than conventional panels and offer long-term peace of mind. These high energy producing, most efficient and reliable solar panels, are fully guaranteed by a 25-year combined product and performance warranty.

The expression ‘you get what you pay for‘ rings very true in the solar industry, and with SunPower you are getting the very best solar system money can buy.

Sunpower Solar Panels – An industry benchmark

It’s a fact: solar panels from SunPower produce the most energy of all solar panels on the market per meter square installed. Since SunPower solar panels are so efficient, you can make the most of your roof space to produce significantly more electricity.

What does this mean for you? Highly efficient SunPower solar panels generate more energy over the lifetime of your system than other panels. Compared to other technologies, SunPower converts the greatest percentage of sunlight into electricity. This means that over the lifetime of your system, you’ll generate more electricity and save more money on your electricity bills.

Not only are SunPower solar panels the most powerful and efficient on the market, they’re also the best-looking. Thanks to the exclusive SunPower® Maxeon Cell Technology , SunPower panels have no grid lines and blend harmoniously into the roof of your home. Backed by the industry’s best warranty, Sunpower solar panels combine brains, brawn and beauty to provide the most efficient, renewable solar energy.

SunPower® E20 Series

Maximum efficiency solar panels

SunPower has introduced a new series of panels that takes the advantages of high efficiency solar technology to another level. The new SunPower E20 series sets a new standard for solar, achieving record panel efficiencies of over 20%.


  • Highest efficiency panels available on the market today, including the world’s first 20% efficiency panel.
  • Maximum performance: The panels that make up the new E20 Series are compatible withtransformer-less (TL) Inverters. This means that SunPower superior panel performance can now be matched with the highest performing inverters, maximising system output.
  • New Positive power tolerance rating: with the SunPower E20 Series you can be assured that you will always get the power you have paid for… or more.
  • The patented SunPower® Maxeon™ cell technology sets the standard for solar performance and reliability, enabling up to 50% more power than conventional solar panels and up to a 3 times more reliable performance. Maxeon solar cells hold the world efficiency record of up to 24%.
  • Guaranteed Performance: The new line of SunPower solar panels is backed by the same industry-leading warranty as the rest of our product offering.

Up to 50% more efficient than conventional solar panels and up to 3 times better reliability. Maxeon cells hold the world efficiency record of 24 percent.

Superior solar panel electricity production

Solar systems are often described in terms of the amount of power they are capable of producing in a given instant (measured in watts or kilowatts). The most important factor to take into account when comparing residential solar systems, however, is the amount of actual electricity the system is expected to generate during its lifetime (measured in kilowatt-hours). When compared to other brands, SunPower® high efficiency solar panels produce the most electricity in a wide range of conditions over the lifetime of the solar system.

More power means fewer panels

With SunPower solar panels you can install more power in the same amount of space than with other panels—up to 50% more than conventional designs and up to four times more than thin-film solar. Since sunpower solar systems require significantly less roof space, you can use fewer panels to produce the same amount of clean, renewable solar power. With fewer solar panels you can also maximise your roof space to choose the best, unobstructed location for electricity production.

More electricity in real-world conditions

  • SunPower panels outperform others early in the morning, late in the day, and on cloudy days.
  • They perform better at high temperatures than others. Because they’re more efficient at converting light into electricity (and not heat), the hotter it gets outside, the better they perform compared to the competition.
  • They maintain efficiency during initial break-in. Most panels lose 3% efficiency when first exposed to sunlight. Not SunPower.

Reliability and quality

The unique design of the Maxeon cell makes SunPower panels almost impervious to corrosion and extreme hot or cold temperature cycles. For every million SunPower panels installed only 27 have been returned under warranty.

Independent tests confirm SunPower produces the most electricity

Universities and independent research laboratories around the world compared the performance of solar panels from SunPower against other technologies. In each case, SunPower solar panels were the clear leader.

Highest efficiency – more watts per square metre ( less panels required for your home )

Highest power production – more energy produced per rated watt ( more savings for you )
