The development of solar energy projects requires accurate estimates of solar irradiance. These data are typically obtained over arbitrary locations using geo-stationary satellite imagery, satellite-to-irradiance models, and other input sources of modeled atmospheric data. This article presents the first uncertainty assessment of this type of modeled solar radiation data for the southeastern Sonoran Desert. The assessment is performed at a single site of high-quality ground measurements for three satellite-based models at the hourly scale over the period 2019-2022 (4 years of data). Model typical uncertainties are presented, providing insights for local solar resource assessment and information for solar industry practitioners. |
