The importance of reliability to the SunShot Initiative (Presentation Recording)

The U.S. Department of Energy’s SunShot Initiative was launched in 2011 to make subsidy-free solar electricity cost competitive with conventional energy sources by the end of the decade. Research in reliability can play a major role in realizing the SunShot goal of $0.06/kWh. By improving photovoltaic module lifetime and reducing degradation rates, a system’s lifetime energy output is increased. Increasing confidence in photovoltaic performance prediction can lower perceived investment risk and thus the cost of capital. Accordingly, in 2015, SunShot expects to award more than $40 million through its SunShot National Laboratory Multiyear Partnership (SuNLaMP) and Physics of Reliability: Evaluating Design Insights for Component Technologies in Solar (PREDICTS) 2 funding programs, for research into reliability topics such as determining acceleration factors, modeling degradation rates and failure mechanisms, improving predictive performance models, and developing new test methods and instrumentation.
