SunPower Releases Performance Solar Panel for Australia's Residential Rooftop Market

The 19-Percent Efficient Solar Panel with Proven Shingled Cell Design Delivers Superior Power,Reliability,Value and Savings Compared to Conventional Panels

MELBOURNE,Australia,Nov. 19,2018 --SunPower Corporation (NASDAQ:SPWR) today launched the 19-percent efficient Performance solar panel for homeowners in Australia,available in several designs up to 325-watts. Backed by SunPower's industry-leading 25-year warranty covering both power output and panel construction,the Performance panel delivers long-term reliability with a unique shingled cell architecture that outperforms conventional panel yield in real-world conditions such as partial shading and elevated temperatures.

"With the high-quality Performance panel,SunPower offers unbeatable value to our customers compared to conventional solar technology," said Chris O'Brien,SunPower Managing Director,Australia. "And as with all our solar solutions,we've leveraged SunPower's 33 years of experience to ensure Performance panels deliver superior aesthetics and a sleek appearance for any roof."

This launch follows the successful 2017 introduction of SunPower's commercial Performance solar panel now integrated into more than 350 projects in Australia,including the 349-megawatt Limondale solar power plant that is currently under construction in New South Wales and Australia's largest solar project to date.

With nameplate manufacturing capacity of over 2 gigawatts,SunPower's Performance solar panels are the most deployed shingled solar panels globally,with proven results. DNV GL,a global independent energy expert and certification body,has named SunPower's Performance solar panel a top performer in all five DNV GL reliability tests which included thermal cycling,damp heat,humidity-freeze,dynamic mechanical load and potential induced degradation.

The Performance solar panel is part of a comprehensive high-efficiency product portfolio that includes SunPower's Maxeon-based X- and E-Series solar panels,and,beginning in 2019,will include its newly developed next generation technology.
