At: EUPVSEC - European PV Solar Energy Conference and Exhibition ; Amsterdam ; 25.9.2017 - 29.9.2017 ; This paper presents a methodology to infer the frequency distribution of the Performance Loss Rate (PLR) of a specific technology from a fleet of PV plants in a region. It is particularly useful in a context of lowinformation, especially when irradiance data is not available for the sites, and it only requires the knowledge of produced energy, location and nominal power of each system of the fleet. This methodology is useful for many actors in the PV market because it allows to calculate representative and accurate values of PLR for a specific region and technology to be used in the planning phase of PV energy projects to predict the exceedance probability of the energy yield.
