SunPower Launches Industry First 400+ Watt Home Solar Panels

Delivering up to 415 watts of electricity, A-Series is the most powerful solar panel that customers in America can buy for their home today.

US-based SunPower has introduced the highest-power solar panels available today for the residential market.

In the United States, the company has launched its Next Generation Technology home solar panel called A-Series, delivering 400 and 415 watts of power. In Europe and Australia, homeowners can also now order a 400-watt solar panel from SunPower called Maxeon 3.

Both the A-series and the Maxeon 3 are the first home solar panel to deliver more than 400 watts in its region and is designed to deliver 60 percent more energy in the same amount of roof space over the first 25 years compared to conventional solar. 

“SunPower is introducing the world’s first 400-watt residential solar panels as most in the industry are just crossing the 300-watt threshold for home solar,” said Jeff Waters, CEO of the SunPower Technologies business unit. “Our record-breaking cell technology and innovative research and development efforts have enabled us to fit more power capacity on rooftops than we ever have before. Our growing panel portfolio is delivering unprecedented value across global markets that go unmatched by any other residential solar technology currently available.”

The Maxeon solar cells are built on a solid copper foundation for high reliability and performance. Making the panels virtually impervious to the corrosion and cracking that typically cause conventional panels to break down. In fact, SunPower claims that its solar panels are shown to have the lowest degradation rate in the industry.

The A-Series panels are built with SunPower’s fifth-generation Maxeon solar cells, called Gen 5, which were perfected at the company’s Silicon Valley Research Facility. This breakthrough Next Generation Technology required new materials, tools, and processes, and resulted in a 65 percent larger cell than previous generations that absorbs more sunlight and ultimately offers more savings to homeowners.

Delivering up to 415 watts of electricity, A-Series is the most powerful solar panel that customers in America can buy for their home today. While the Maxeon 3 is the most powerful home solar panel in Europe and Australia crossing the 400-watt mark.
