Detecting Calibration Drift at Ground Truth Stations A Demonstration of Satellite Irradiance Models' Accuracy

In this article we show how a state-of-the-art satellite irradiance model - Solar Anywhere - is capable of undetected calibration issues at a trusted reference ground truth irradiance measurement station. This evidence suggests that the best satellite models have now achieved a degree of accuracy and versatility that makes them an acceptable, if not a preferred choice, for solar energy engineering applications ranging from long-term site characterization and system monitoring.
