The Sunpower E18 & E19 AC solar panels offer residential customers increased flexibility, as panels with microinverters can be easily installed on most homes, including those with complex rooftops or shading from trees, chimneys and other obstructions. Power generated by the rooftop solar system is optimized at the individual solar panel level, delivering a greater overall energy yield, and is easily monitored to ensure maximum power is being produced. The attractive design of the AC solar panels, combined with the most efficient and reliable solar technology, are backed by SunPower’s industry-leading 25 year warranty. Microinverters are integrated with SunPower’s solar panels at the factory level, reducing installation time, complexity and overall cost of the system.

SunPower AC solar panels are integrated with the industry-leading SolarBridge Pantheon™ microinverter. The all-black, aesthetically pleasing E18/225 watt AC solar panel and the maximum-efficiency E19/240 watt AC solar panel will be available in the U.S. in early 2012. The AC panels feature SunPower’s 22.4 percent efficient patented Maxeon™ cell technology. The all-back contact Maxeon solar cell captures significantly more sunlight and conducts more electrical current than conventional solar cells, and holds the world record for efficiency among commercially available, mass-produced solar cells.
