[Episode #229] – US Distributed Solar Potential

What is the full potential for distributed solar power in the US?

Many models have been developed to explore how a decarbonized US energy system could look, consistently finding that solar power would be the dominant source of electricity. Yet, we don’t really know the full potential for distributed solar. Even the term “distributed solar” isn’t very well-defined, potentially referring to many different kinds of solar power installations.

In today’s conversation, we review the available estimates for small rooftop and ground-mounted systems typically found on buildings, solar panels on canopies over parking lots, and innovative floating solar arrays over bodies of freshwater. Additionally, we explore emerging options such as installations on brownfield sites, agricultural lands, and alongside roadways.

Then we add it all up to see how big of a role distributed solar could actually play in a fully decarbonized US electricity system—with a surprisingly large result! But you’ll have to be a premium member and listen to the end to find out what it is.

In this episode, we are joined by Robert Margolis, a Senior Energy Analyst with the Strategic Energy Analysis Center at the National Renewable Energy Laboratory (or NREL), which is part of the US Department of Energy. With more than 20 years of focused research on solar in the US, and his deep familiarity with energy technology and policy and energy-economic-environmental modeling, he is one of the top experts on the potential for distributed solar in the US.

Guest:

Robert Margolis is a Senior Energy Analyst in NREL’s Strategic Energy Analysis Center. Since joining NREL in 2003, he has served as key advisor to the U.S. DOE’s Solar Energy Technologies Office. In this role he has helped to define and carry out a broad analytical agenda focused on examining the potential for and challenges related to wide-spread adoption of solar energy. He led the Solar Futures Study (2021), the On the Path to SunShot Study (2016), and the SunShot Vision Study (2021). His main research interests include energy technology and policy; research, development, and demonstration policy; and energy-economic-environmental modeling.
