Use and Benefits of the Combination of PV and Meteorological Networks

Weather forecasts are already used to optimise the use of PV energy in private and industrial applications. Standard methods as numerical weather prediction (NWP) or satellite data have usually reduced update intervals and geographical scale. Especially forecasting in a very short time and scale (e.g. nowcasting) is a complex task why in latest researches all-sky imagers or so called sky cams are used. Additionally a high number of installed PV systems can provide online data of current power or sensor values. The aim of the project PV-go-Smart (10/17 – 09/19) is the combination of multiple data sources in different models to provide accurate and highly resolved solar resource forecasts.
