Solar Forecasting for Grid Flexibility During the conference program, Marion Lafuma, Sales Manager at
Reuniwatt is excited to announce its participation in the European Geosciences Union (EGU) General Assembly 2026, where we will present our latest work on photovoltaic soiling losses. Join us for our poster session on 📍Monday, 04 May 2026, from 16:15–18:00 (CEST) at Hall X4, Display time from 14:00–18:00.The session will feature our presentation titled Hybrid physical-machine learning estimation of photovoltaic soiling losses from meteorological reanalysis
A wide range of observation systems, including Earth-orbiting satellites, atmospheric weather balloons, ships, ocean buoys and remote stations, makes the forecasts possible that people use every day and provide the foundation for early-warning systems. But meteorological observation is fundamental not only for public weather forecasts, but also for safety, resilience and decision-making across sectors. Observation is also central to innovation in aviation. Contrail avoidance
Utilities can’t run a solar-heavy grid on optimism alone—they need dependable forecasts from days ahead down to minutes ahead. In pv magazine (12/2025 & 01/2026), Reuniwatt’s Hannah Bergler describes what it takes to deliver that reliability for a mega-scale PV project in the United Arab Emirates, where desert conditions push both O&M and forecasting systems to their limits. Desert solar means forecasting under pressure
Sunology, the French leader in residential solar stations without installation or assembly, has renewed its partnership with Reuniwatt, an international reference in solar irradiance estimation and forecasting. This collaboration has enabled the development of a highly scalable solar forecasting innovation aimed at optimizing residential solar energy storage management. Innovative start-up in residential solar solutions Sunology is a Nantes-based start-up developing a new generation of
On December 10–11, Reuniwatt’s team will be present at the Energaia Forum 2025 in Montpellier, France. You can meet us in Hall B1, Booth D-01. Meet Reuniwatt at Forum EnerGaïa 2025! Forum EnerGaïa brings together regions, cities and industries looking for practical solutions to accelerate their energy transition. Our team will showcase how instruments such as our Sky InSight™ infrared all-sky imager and Sky
[Webinar Series] Harnessing the Power of Destination Earth – Part 2: Digital Twins Driving the Future of Energy Risk Management EO4ER has been selected by ESA to develop a Digital Twin Component prototype for the energy sector. EO4ER’s consortium is composed of IT and cutting-edge software development specialist OHB Digital Services, THU’s application-orientated Smart Grids Research Group and cloud estimation and solar forecasting expert Reuniwatt.
Reuniwatt is excited to announce its participation in the upcoming IEEE International Conference on Space Optical Systems and Applications (ICSOS 2025), taking place from October 28 to 31 in Kyoto, Japan. This event gathers the brightest minds and innovators in space optical communication, providing a perfect platform to present the latest advances in assessing atmospheric impacts on Free Space Optical (FSO) communications. Presenting Cutting-Edge
We’re 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
Unlike traditional radio frequency systems, lasercomm offers dramatically higher bandwidth and enhanced security, making it a key enabler for next-generation satellite missions and data-hungry applications. However, this leap in capability comes with new vulnerabilities—particularly the sensitivity of optical signals to atmospheric conditions. Even minor disruptions, such as cloud cover or atmospheric turbulence, can severely degrade or interrupt the laser link between space assets and ground
