Blind photovoltaic modeling intercomparison: A multidimensional data analysis and lessons learned

The Photovoltaic (PV) Performance Modeling Collaborative (PVPMC) organized a blind PV performance modeling intercomparison to allow modelers blindly test their models and ability against real system data. Measured weather irradiance data were provided along with detailed descriptions of systems from two locations (Albuquerque, New Mexico, USA, Roskilde, Denmark). Participants asked simulate the plane-of-array irradiance, module temperature, DC power output six submit results Sandia for processing. showed overall median mean bias (i.e., average error per participant) 0.6% in annual irradiation −3.3% energy yield. While most seem exhibit higher precision accuracy as compared an earlier study 2010, human errors, skills, derates found still cause significant errors estimates.
