Solar Energy Evolution and Diffusion Studies (SEEDS)

Solar photovoltaic panels are an increasingly competitive player in the energy market as the technology improves and the prices drop. The challenge of widespread diffusion is now behavioral as much as economic. Through large-scale experimentation, SEEDS is testing which strategies and messages are most conducive to solar adoption.

Solar Energy Evolution and Diffusion Studies (SEEDS)

What motivates people to install rooftop solar panels? Which incentives or policies can rapidly boost the adoption of this technology? Which programs are persistently effective, and which are most easily scaled? The answers to these questions are essential for promoting a sustainable energy future.

Supported by the U.S. Department of Energy SunShot Initiative, a multidisciplinary set of partners came together to test these questions by examining the uptake of solar through the Solarize CT program. Out of this collaboration, we have produced a guidebook for community and business leaders, active citizens and policymakers detailing the most effective strategies for accelerating the adoption of residential solar.

About the Partnership

The Yale School of Forestry and Environmental Studies and Duke University, in collaboration with the CT Green Bank and SmartPower, conducted a series of rigorous controlled field trials to better understand the adoption of residential solar.

The Yale Center for Business and the Environment coordi­nated the partnership and worked with a team of students to facilitate the research, assist with the data analysis and create this guidebook.

The Connecticut Green Bank, a state-level institution devoted to expanding the region’s clean energy sources, accelerated consumer financing options by developing risk-reduction mech­anisms in partnership with local lending and capital partners.

SmartPower, a social marketing firm, provided insight and support for Solarize CT, creating high impact on-the-ground community campaigns.
