Sky-camera based forecasting systems for solar PV generation are now a commonly used technology, and the value proposition for this technology in the specific context of small microgrids has been made clear. However, that value remains unproven. We provide results from an off-grid hybrid system in which a sky- camera forecast system is integrated into a solar PV ramp-rate control system. The results and supporting analysis demonstrate that the skycamera was successfully able to predict almost all significant drops in solar resource, and its integration resulted in a significant reduction in the utilisation of co-located battery system used for ramp-rate control.
