Highest-wattage home solar panels available, period
First 400 Watt Solar Panel For Home Installations
SunPower has officially released its A-Series of solar panels, including 400, 415, and 420 watt panels, with efficiencies of 22% +. This makes this series of solar panels the most efficient on the market, meaning you can create more power with less panels on your roof.
In this video, SunPower by Stellar Solar Co-Founder Michael Powers explains why you should install the A-Series panels, and goes over the benefits of having the most efficient solar panels available on your roof.
Introducing the next big step in solar
Record-breaking power
Set a record of your own with the world’s first 400-watt solar panels, providing more power than ever before from fewer panels on your roof.
A solar panel is only as good as the cells inside. The SunPower® Maxeon® Gen 5 solar cell is 65% larger than prior generations, converting more sunlight into electricity.
Maximum production
Factory-integrated microinverters boost production at the source, helping A-Series panels deliver more power per square foot than any other commercially available solar.*
Elegant styling
Designed to blend harmoniously into your roof, delivering a sleek, premium aesthetic that can accommodate a variety of architectural styles.
Peace of mind
The Equinox™ system is backed by the only home solar warranty to cover your whole system (not just the panels). That means you never have to wonder which company you can depend on. We’ve got you covered for 25 years—including performance, labor and parts.*
A complete system, designed to work together
Gone are the days of clunky, piecemeal solar systems. The Equinox™ system is the only complete home solar system that is designed and engineered by one company. From the highest efficiency panels available* to energy monitoring software, every component is designed to work together perfectly—from sun to switch.
