We\u2019re looking forward to meeting experts and stakeholders at the EUMETSAT Meteorological Satellite Conference 2025, taking place from 15 to 19 September in Lyon, France. This event is the perfect opportunity for us to share our latest research and innovations in satellite-based solar irradiance monitoring. Reuniwatt will present new advances in surface solar irradiance (SSI) retrieval using data from the cutting-edge Meteosat Third Generation (MTG) satellite.<\/p>\n
Surface Solar Irradiance (SSI) is a critical parameter for monitoring photovoltaic (PV) power plant performance, enabling detection of drops in electricity production using satellite datat without the need to use and maintain ground-based instruments.<\/span> Since the launch of the first MTG imaging satellite (MTG-I1) in December 2022, equipped with the Flexible Combined Imager (FCI), new opportunities have arisen to improve SSI estimates with higher spatial and temporal resolution imagery. Reuniwatt has developed a real-time SSI retrieval method utilizing raw FCI visible channel data by converting image counts into radiances and reflectances, then deriving a cloud index. This cloud index, combined with EUMETSAT\u2019s cloud mask and a clear sky model, enables accurate calculation of effective solar irradiance and corresponding PV output.<\/p>\n Our preliminary study covers data from October 2024 to July 2025, comparing our model\u2019s output with high-quality solar radiation measurements across Germany, France, Spain, and the Netherlands. The results demonstrate how MTG data can significantly improve solar irradiance monitoring and PV performance assessment in Europe. Our poster\u00a0will be presented in Lyon:<\/p>\n Turpin M., Roussel G., Marchal S., Schmutz N., Preliminary assessment of Surface Solar Irradiance retrieval from Meteosat Third Generation satellite, EUMETSAT Meteorological Satellite Conference 2025, 15-19 September 2025, Lyon, France.<\/span><\/p>\n General viewing will be from Monday to Friday during the coffee and lunch breaks. In addition, we’ll be presenting our study during the dedicated poster session on Tuesday, 16 September from 16:00 \u2013 18:00.Meet Reuniwatt in Lyon<\/h2>\n
\nWe\u2019re excited to present our findings \u2014led by Mathieu Turpin \u2014at the conference. We invite you to join us in Lyon to explore how new satellite technologies are advancing renewable energy monitoring and forecasting.
