Extreme hail events pose a serious risk not just for people but also for business and assets. Due to their nature this is particularly true for utility-scale solar parks. Accurately assessing the risk of extreme hail is therefore critical when planning, developing, and operating large-scale solar farms. Yet, the challenge is compounded by limited, noisy historical data and the unpredictable nature of severe weather events. In this talk, I will show how a range of statistical and simulation methods can be used to estimate hail risk—even in situations with limited or noisy data.
