TL;DR: An approach to predict regional PV power output based on forecasts up to three days ahead provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) and an approach to derive weather specific prediction intervals for irradiance forecasts are presented.

TL;DR: In this article, the HELIOSAT method applied to derive surface solar irradiance from satellite images is described and shown examples of applications: the use of daylight in buildings, the generation of correlated time series of solar irradiances and temperature as input data for simulations of solar energy systems and a short-term forecast of sun irradiance which can be used in intelligent building control techniques.

TL;DR: In this article, three independent validations of global horizontal irradiance (GHI) multi-day forecast models were conducted in the US, Canada and Europe, and two models are common to the three validation efforts: the ECMWF global model and the GFS-driven WRF mesoscale model.

TL;DR: In this article, a new type of solar irradiance scheme is developed based on radiative transfer models (RTM) using atmospheric parameter information retrieved from the Meteosat Second Generation (MSG) satellite (clouds, ozone, water vapour) and the ERS-2/ENVISAT satellites (aerosols, ozone).

TL;DR: The Heliosat method is a widely applied procedure for estimating solar irradiance fluxes at the earth's surface as discussed by the authors, which is based on the empirical correlation between a satellite derived cloud index and the irradiance at the ground.
