The Planet’s Most Powerful Solar™
SunPower™ solar panels are the most efficient on the market today, thanks to the revolutionary SunPower™ Maxeon™ solar cell technology. SunPower panels generate more electricity than competitors' solar panels, outperforming conventional panels-even on cloudy days or in high temperatures over the lifetime of the solar system.
Highest Efficiency Solar Panels
This patented technology places the metal contacts on the back side of the solar cells, giving us an unobstructed surface area to collect the sunlight. We use only the best, premium, monocrystalline silicon with a patented treatment to optimise energy conversion. The result: Our solar panels capture more sunlight and convert this light into energy more efficiently than any other solar panel on the market. And because SunPower solar panels have proven to be the most efficient solar panels on the planet, our experience tells us they’ll also help you save the most on your utility bills.
More Electricity in Real-World Conditions
- SunPower panels outperform others early in the morning, late in the day, and on cloudy days.
- They effectively absorb different wavelengths of light to generate more electricity.
- 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.
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.
* Arizona State University: 7% more than Poly-Si (Test dates: June – Aug 2008); Loughborough University (CREST): 9% more than Poly-Si (Test dates: 2007-2008); University of Stuttgart (IPE): 7% more than HIT (Sanyo), 16% more than thin film (Test dates: June 2006 – May 2009); University of Cyprus: 7% more than a-Si (Mitsubishi), 16% more than Mono-Si (BP Solar) (Test dates: June 2006 – May 2009).
Highest Reliability
If you're looking for reliable solar, look at the facts. SunPower™ solar energy systems are the most reliable in the world. Why? Because we've taken millions of hours of performance analysis and reengineered it back into the design of our panels. Our proprietary SunPower Maxeon back-contact solar cell design means that our panels hold up under harsh conditions-much better than most of our competitors.
And because the real-world is hard on solar panels, our testing goes above and beyond industry standards. In fact, we test far more rigorously than anyone in the industry. As a result, our Highly Accelerated Lifetime Tests are much more rigorous than anyone in the industry. In a side-by-side comparison, our panels continue to maintain high performance and don't degrade like most competitor panels.
As a result, our panels are rock-solid against hail stones, tough against humid climates, stand up to extremely high temperatures, and can endure hurricane-force winds.
Bottom line: When you're buying solar, reliability is crucial. And SunPower systems are the most rigorously tested and reliable in the world.
