logo SHCIEA SHC Task 46: Solar Resource Assessment and Forecasting

International Energy Agency (IEA), Collaborative Agreement on Solar Heating and Cooling (SHC) Task 46 Solar Resource Assessment and Forecasting.

  • Task 46 addresses four basic objectives in improving our understanding of solar resources:
  • Evaluation of solar resource variability that impacts large penetrations of solar technologies;
  • standardization and integrating procedures for data bankability;
  • improving procedures for short-term solar resource forecasting;
  • advanced solar resource modeling procedures based on physical principles.


IEA SHC Task 36

logo SHCInternational Energy Agency (IEA), Collaborative Agreement on Solar Heating and Cooling (SHC) Task 36 "Solar Resource Knowledge Management". Task 36 develops benchmarking and quality assessment procedures of solar resource information derived from surface-based and satellite-based platforms; it improves access by the users through various web-based hosting schemes, and improves input data sets and algorithms from which satellite-derived products are produced, including short term forecasting and climatic variability of the solar resource.


logo MESORManagement and Exploitation of Solar Resource Knowledge (MESoR) is a Collaborative Action within 6th Framework Programme of the European Union. The activities focus on: guiding the users of solar radiation data, unifying access to the existing databases by the advance information infrastructure, connecting to the other relevant activities, and the dissemination of knowledge. Experts from GeoModel Solar have participated on the project during their stay at the European Commission, Joint Research Centre in Ispra (Italy).
