''Long-term'' forecasting usually refers to forecasting techniques applied to time horizons on the order of weeks to years. These time horizons can be relevant for energy producers to negotiate contracts with financial entities or [[Public utility|utilities]] that distribute the generated energy.

In general, these long-term forecasting horizons usually rely on [[Numerical weather prediction|NWP]] and [[Climatology|climatological]] models. Additionally, most of the forecasting methods are based on [[Mesoscale meteorology|mesoscale]] models fed with reanalysis data as input. Output can also be postprocessed with [[Statistics|statistical]] approaches based on measured data. Due to the fact that this time horizon is less relevant from aan operational perspective and much harder to model and validate, only about 5% of solar forecasting publications consider this horizon.
