Planting the “SEEDS” of Solar Technology in the Home

Data-rich predictive models help determine which consumers buy solar equipment and why.

In an effort to better understand what persuades people to buy photovoltaic (PV) systems for their homes, researchers at Sandia National Laboratories are gathering data on consumer motivations that can feed sophisticated computer models and thus lead to greater use of solar energy.



A primary goal of the project is to help increase the nation’s share of solar energy in the electricity market from its current share of less than .05 percent to at least 14 percent by 2030. This is the second year of a three-year effort.

“If we can develop effective and accurate predictive models, we can help identify policy variables that could increase purchases of residential PV systems and ultimately help advance the mission of the SunShot Initiative,” said Kiran Lakkaraju, Sandia’s project lead. Specifically, he said, an effective model of solar purchase dynamics can be used to predict and even influence consumer purchasing decisions.

The modeling project, part of the Solar Energy Evolution and Diffusion Studies(SEEDS) program, is one of many activities in the Energy Department’s SunShot Initiative, which seeks to make solar energy cost-competitive with other forms of electricity. SEEDS projects are designed to investigate methods for transforming the operations of solar researchers, manufacturers, developers, installers and policymakers.

The projects will be discussed at a May 22 workshop at the Department of Energy’s SunShot Grand Challenge Summit. The event takes place May 19-22 in Anaheim, Calif.

Sandia’s solar energy program includes deep research and development in areas such as PV systems, concentrating solar power, grid integration and solar codes and standards.

Computer Models Predict Homeowners’ Likelihood to Buy, Invest in PV Systems  ::)

Sandia’s approach is to collect and analyze large amounts of data, said Jerry McNeish, manager of the labs’ quantitative modeling and analysis group. The information has led to two different models, one that predicts how likely an individual is to buy a PV system and one that predicts how long that individual will take to make the investment.

Working with project partners at the National Renewable Energy Laboratory (NREL) and the California Center for Sustainable Energy (CCSE), project researchers are conducting surveys of consumers in San Diego County, including 1,000 respondents who have bought PV systems and another 1,000 who have not. Data from the surveys will be studied by Sandia and Vanderbilt University quantitative modeling experts and fed into modeling tools.

CCSE leads the market characterization of the San Diego regional solar market, including focus groups, pilot programs and field testing of messages.

Experiments Analyze Effectiveness of Incentives, Framing of Messages  ::)

Additional data is being collected for the Sandia project via a field experiment conducted by collaborator The Vote Solar Initiative, which will analyze how consumers respond to economic incentives, discounts and even peer effects when friends, family or co-workers purchase PV systems.

The questions on the surveys were influenced by the results from the initial predictive models and touch on issues such as environmental awareness, energy independence and information about life events.

Another experiment, conducted online by The Wharton School at the University of Pennsylvania, is exploring how the framing of messages can influence whether consumers will invest the time to learn more about installing PV systems. Researchers will examine how different demographic segments are influenced by messages and will study the influence of such issues as environmental awareness, energy independence, information about life events and how messages are received.

Other predictive variables, including the square footage of homes, the national unemployment rate and even seemingly inconsequential factors, such as whether consumers own a swimming pool, are also part of the models.

Consumer Data Models Will Help Identify Likely Solar Buyers  ::)

“We’re essentially creating a model that predicts household solar energy system purchases based on such variables as price, energy savings, environmental concerns and other factors,” said Lakkaraju. “But then we’re also running experiments that feed results back into the model. We have a cycle where we use the model to test and generate hypotheses about solar panel purchases, but then we test these hypotheses through experiments to improve the model.”

The Sandia-developed models, Lakkaraju said, have already predicted purchasing behavior 200-500 percent better than current models.  ::)

The team also is investigating novel financing structures that go beyond straightforward “purchases,” such as third-party ownership through leasing or power purchasing agreements. These aren’t strictly purchases yet are seen as key to the industry’s growth, Lakkaraju said.

The research team will test their modeling tools, recommendations and draft guidance on using the models in additional field experiments. 

“The significance of this work is that it will help identify those likely to purchase PV systems and help forecast future market trends,” said Lakkaraju. “Ultimately, it will help those in the solar industry to more effectively bring solar energy to consumers.”  ::)

All well and good. But let us never forget that the Federal Reserve can facilitate the transition to solar energy simply by providing the same (or a percentage point lower as an incentive) financing capital for carbon neutral home refits and new homes with solar and other renewable energy technologies. This is a problem that CAN OBVIOUSLY and SUSTAINABLY be fixed by throwing money at it. 

Of course, we know why the Federal Reserve will CONTINUE to throw money at the pernicious habits of Wall Street that are ruining our economy and defending the fossil fuel criminal syndicate both inside an outside of our government, don't we? It's what predatory, conscience free, pollute and don't give hoot Capitalism is all about.  >:(

The newly released book, "Let it Shine", brings to light newly discovered documents suppressed by the Nixon, Carter and Reagan Administrations, that if known at the time by the public and the Congress, solar energy would have definitely played a larger role in the American energy scene during the last forty years.
