In the U.S., solar PV market continuous growing in both utility-scale and small-scale projects, whereas residential segment seems to boost. SunPower recently launched a new solar panel series with its highest power efficiency for supplying its customers across the U.S.

SunPower’s X-Series solar panels has been tested and verified by the NREL that the panels have efficiency up to 22.8%, a new world’s record. X22, the newest product of SunPower’s X-Series lineup, offers efficiencies of more than 22%, generating 70% more energy in the same space compared to conventional panels with 15~18% efficiencies.

“Solar technology differs widely from brand to brand, so it’s important for consumers to consider that not all panels deliver the same amount of energy, look elegant on a roof, or are guaranteed to last as long as promised,” said Howard Wenger, SunPower president, business units.


SunPower has been focusing on delivering high efficient solar technologies to its customers – including 500,000 home projects worldwide. SunPower has also involved in several world-class innovations and bold projects. For example, Tûranor PlanetSolar is the world’s largest solar boat and is powered exclusively by SunPower solar cells. Solar Impulse 2, an experimental airplane with 17,000 SunPower solar cells covering its wings, made the longest piloted and solar-only flight traveling 5,000 miles from Japan to Hawaii just last year.

Over the past five years, SunPower has broken the industry’s efficiency record by four times:

  • 19.5% efficiency in May 2010 with E19 solar panel
  • 20% efficiency in July 2011 with E20 solar panel
  • 21% efficiency in April 2013 with X21 solar panel
  • 22% efficiency in November 2015 with X22 solar panel

The E-Series and X-Series panels are currently available in the U.S., while the E-Series and X21 solar panels are available in Europe, Japan and Australia.

Throughout its history, SunPower now launches “Demand Better Solar” Campaign to further prompt solar power to the world.
