Most Reliable Solar

If you’re looking for reliable solar power technology, 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 them back into the design of our solar cells, solar panels and solar energy systems.
 

Proven, Reliable Solar Technology

As proven by more than a quarter-century of experience, SunPower® solar technology can be relied on to outlast other leading technologies. Our proprietary SunPower® Maxeon® back-contact solar cell design enables our solar panels to hold up under harsh conditions—much better than those of our competitors.

Solar Systems Designed for the Real-World

Because the real-world is hard on solar panels, we test our panels far more rigorously than anyone in the industry.  

As a result, SunPower solar energy systems stand up much better than others to:

  • Temperature swings
  • Moisture and humidity
  • Intense loads
  • Shading

25 Years of Reliable Solar Energy

When you’re buying solar, reliability is crucial. And SunPower solar energy systems are the most rigorously tested, most reliable solar power systems you can buy.  The bottom line? SunPower panels are designed for the real world. And exhaustive testing ensures that SunPower systems perform consistently, hassle-free, for well over 25 years.
