Increasing the temporal resolution of direct normal solar irradiance forecasted series [PDF]
AIP Conference Proceedings, 2017 A detailed knowledge of the solar resource is a critical point in the design and control of Concentrating Solar Power (CSP) plants. In particular, accurate forecasting of solar irradiance is essential for the efficient operation of solar thermal power plants, the management of energy markets, and the widespread implementation of this technology ...

Prediction of Circumsolar Irradiance and Its Impact on CSP Systems under Clear Skies
Energies, 2023 In this work, a model to estimate circumsolar normal irradiance (CSNI) for several half-opening angles under clear skies was developed. This approach used a look-up table to determine the model parameters and estimate CSNI for half-opening angles between

Intercomparison of 51 radiometers for determining global horizontal irradiance and direct normal irradiance measurements [PDF]
Solar Energy, 2016 Abstract Accurate solar radiation measurements require properly installed and maintained radiometers with calibrations traceable to the World Radiometric Reference (WRR). This study analyzes the performance of 51 commercially available and prototype radiometers used for measuring global horizontal irradiances (GHI) or direct normal irradiances (DNI).
