The world’s most powerful solar.

Now with a 25 year industry-leading warranty on production and construction of every module!

Highest Efficiency

Not all solar panels are created equally. In fact, there’s a huge range in efficiency. So, if you’re looking for efficient solar, look at the facts.

SunPower solar cells currently hold the world record in efficiency at 22.4 percent. And that’s why SunPower solar panels deliver up to 50 percent more energy than conventional panels.

How do they do it? With their revolutionary patented, all-back contact, SunPower Maxeon solar cell technology.

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 they’ve taken millions of hours of performance analysis and re-engineered it back into the design of their solar cells, solar panels, and solar energy systems.

SunPower’s proprietary Maxeon back-contact solar cell design means that their panels hold up under harsh condition — better than any competitor.

Guaranteed Performance

From end to end, SunPower guarantees the highest level of solar energy performance. Installation is fast to minimize disruption.

And SunPower panels perform. Ten years of comprehensive data show that their panels deliver 105% of their expected energy production.

Plus, they’re built to withstand real-world conditions, so your long-term maintenance costs are impressively low — with an impressively high 98% uptime.

And your solar panels come with a 25-year warranty. But we don’t think you’ll need it. SunPower solar panels are designed to last longer than that.
