Ground-measured solar data is often treated as the ground truth. It is used to evaluate PV plant performance, validate models, adapt satellite-based datasets to local conditions, calculate expected production, and assess whether an asset is performing as it should. But measured data is never perfect. Instrument faults, installation issues, environmental effects, soiling, shading, calibration drift, and sensor misalignment can all introduce errors.
The Solargis team recently joined the Photovoltaic Performance Modeling Collaborative (PVPMC) 2025 Workshop, held on 29–30 October in Ayia Napa, Cyprus. This year’s event brought together leading experts in PV performance modeling, system analytics, and solar energy integration, with a special focus on the challenges and solutions of island grids.
We spoke with Jozef Dudzak, Data Scientist, and Marketa Jansova PhD, Data Applications Team Leader, about the role of a Solar Data Specialist – and how the Solargis Analyst software transforms complex resource analysis in the solar sector.
