Dr. Richard Swanson, Founder, President and Chief Technical Officer, SunPower, shares details about efficiency and system costs in part two of our solar panel efficiency video series

This week’s blog post is the second installment of our three-part series with solar expert Dr. Richard Swanson.

In this installment Dr. Swanson explains why solar panel efficiency is such an important variable when calculating ROI and the total cost of a solar installation.

As Dr. Swanson explains:

"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" of efficiency, and why SunPower continually strives to improve solar panel efficiency.

In the final installment of this series next week, Dr. Swanson will walk you through SunPower’s history of solar cell efficiency and where it is headed in the future. If you crave more solar discussions, but just cannot wait a week, join our Facebook community at www.facebook.com/sunpower.
