Dr. Richard Swanson, Founder, President and Chief Technical Officer, SunPower explains that "Efficiency is probably the single most important number in determining the cost of the electricity you get from the solar system."
So, please take a minute and learn about the "very dramatic effects" efficiency has, and why SunPower continually strives to increase efficiency.
Uh, so why are your products outrageously expensive?

SunPower now provides "adjusted efficiency" numbers. However SunPower provides different adjusted efficiency numbers for comparing against 11% efficiency panels and 14% efficiency panels. How can this be? How can SunPower's efficiency depend on the characteristics of a competitor's panels?
