Abstract

We report on estimation of the solar energy potential in Greece using satellite- and ground-based observations in conjunction with radiative transfer model (RTM) simulations. Pyranometers of the Hellenic Network for Solar Energy and the National Observatory of Athens provide accurate insolation measurements and are used to verify 1- and 2-day ahead forecasts provided by the mesoscale model MM5. The total energy potential for each ground station is found to range from 1.5 to 1.9 MWh/m2 with cloudiness causing increments in the forecast error of the order of 10 %. We also present a model for generating instantaneous and accurate gridded surface solar radiation spectra and budgets via a synergy of large (2.5 M record) RTM look-up tables and neural networks (NN). We demonstrate that NNs fed with cloud inputs retrieved from the Spinning Enhanced Visible and Infrared Imager onboard the Meteosat Second Generation 3 satellite are able to produce maps of the Earth disk at high resolution (1 nm, 0.05 × 0.05 degrees, 15-min) and we cross-validate them with other models to guarantee the quality and accuracy of the irradiance products. We show that these complimentary approaches are ideal for correct assessments of the solar energy potential and for providing accurate solar energy applications in real-time.
