How Solar Works – Understanding The Differences

SunPower® Equinox™ is the only all-in-one, complete home solar system. With a conventional solar system, it’s hard to know what you’re getting. And while an installer may tout that variety is a strength, it’s more likely a warning sign. Inconsistent product strategies and standards are no guarantee that you’ll be happy with the end result.

Unmatched Performance, Reliability And Aesthetics

Our top-of-the-line solar panels provide homeowners with more energy. They deliver the highest efficiency available in a residential solar panel today, at a record-breaking 22.8%. That means homeowners get more electricity, more flexibility, more peace of mind, and lower electricity bills.

X-21 335 Watt Signature Black
Aka, The Hottest Panel On The Block!

Maxeon® AC modules, which include a factory-integrated Maxeon microinverter, provide a revolutionary combination of high efficiency, high reliability, and module-level DC-to-AC power conversion. Designed specifically for use with Maxeon InvisiMount™ and the Maxeon Monitoring System, SunPower AC modules enable rapid installation, best-in-class system aesthetics, and intuitive visibility into system performance. All this comes with the best Combined Power and Product Warranty in the industry. 

Maxeon’s new Type D AC module is UL-tested and certified to UL 1741 SA and provides advanced smart inverter functions. Maxeon Type D AC modules are fully compliant with the California Rule 21 Phase 1 requirements, and the Rule 21 grid profile is easily set during commissioning with Maxeon PVS5x monitoring hardware.

X-21 345 Watt Panel
More Efficiency, Lower Electric Bills

Because X-21 345 Watt residential solar panels generate more electricity from a smaller area, you can expand energy production simply by using additional roof space to add more panels at a later date.

Our panels guarantee more power and more peace of mind. We also offer the best-combined power and product warranty for 25 years. And because our panels are built on a solid copper foundation, Maxeon ® solar cells deliver unmatched reliability over the lifetime of your solar energy system.

The X-21 345 Watt - The most efficient X-Series Solar Panel
X-22 360 Watt Panel
Most Power, Less Space

Our X-22 360-watt panels produce the most energy and take up much less space. They boast the highest efficiency available on the market by any manufacturer and deliver 44% more power per panel, which means you can generate more power in smaller spaces with fewer panels. Simply put, these panels convert more sunlight into electricity, producing 75% more energy per square foot over the first 25 years. X-22 panels are designed for durability using the Maxeon Solar Cell, the only cell built on a solid copper foundation. These cells make the panels virtually impervious to the corrosion and cracking that degrade conventional panels. X-22 panels rank #1 in the Fraunhofer durability test and have 100% power maintained in the Atlas 25+ comprehensive durability test.
