Biography

Yehia Eissa holds the position of Chargé de recherche within the SciDoSol Sponsorship Chair at the Centre Observation, Impacts, Energy (O.I.E.), Mines Paris – PSL, at the Pierre Laffitte campus in Sophia Antipolis. Within the International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS), he leads Subtask 3 (Focus Topics) of Task 16: Solar Resource for High Penetration and Large-Scale Applications.

His research aims to improve understanding of the downwelling surface solar resource through physical and empirical modelling, satellite imagery, atmospheric monitoring data and advancing in situ measurements. Through advancing knowledge of the solar resource, his work supports the shift toward renewable energy solutions.

Alongside research, he supervises PhD and engineering students, as well as semester-long hands-on student projects. He also organizes and teaches at the Solar Winter School, an annual week-long school. His teaching covers the fundamentals of solar radiation, measurement and modelling techniques, and the solar resource for concentrating collectors and solar cookers. He has also previously taught physics.

Projects

  • 2024-2027 SciDoSol Scientific Director SciDoSol (Data Science applied to Solar Energy) is a research chair hosted at the Centre Observation, Impacts, Energy (O.I.E.) of Mines Paris – PSL, in Sophia Antipolis. Launched in 2023 and planned until 2027, it is funded by five industrial partners: TotalEnergies, RTE, SOMFY, TSE, and CalibSun. Its scientific objective is to improve the accuracy of estimates of downward and reflected solar radiation. It aims for finer spatial and temporal resolutions, with particular attention to spectral and angular domains. Its activities are organized around three pillars: - Open research: estimating irradiance via satellite and deep learning, hemispheric sky imaging, modeling variability, and in situ measurements. - Teaching and training: Solar Winter School, IBE3 project, UNDERSOLAR trimester, and internships. - Transfer to industry and society: - a Tier 1 measurement station with data open according to FAIR principles; - the ABC-Rad dataset; - an open-source, low-cost hemispheric imager (all-sky imager); - participation in IEA PVPS Task 16.
